4:10 gears, what to expect??

[CodeMan]

15047 Purchased my 03 Marauder in August 2008. (36k miles) Shortly after purchase I joined MM.net. Thanks to this website, I was able to read several opinions on different upgrades other owners have purchased. After careful review, I bought a tuner from Reinhart & very happy with how the Marauder performs!! But now...I am ready to shop for the next item on my wish list. I could use everyone’s assistance on the 4:10 gears. In conjunction with the current Reinhart tune (4:10 tune included), what can I expect in the overall performance when adding 4:10 gears & switching the tune to match?? (long distance trips and street light to street light)

Thanks for your help. :bows:

[Hotrauder]

Measurable performance increase off the line. Minimal decrease in fuel mileage and speedo error of a mph or two low at 75 depending on tires. You will be able to smoke em off the line if your tune is any good at all. :2thumbs:Dennis...go for it, NOW.

[CKMustangCobra]

4.10s are on my short list of mods.

[Vortech347]

Can't beat em with a stick.

[CodeMan]

Terrific!!! Thanks for the advice. I will be ordering them immediately!!!

[lincolnpimp]

Make sure they are installed by a VERY experienced person, otherwise order 2.

[oldekid]

You shouldn't notice anything for 200 miles. There is a breakin period.

After that, just have fun.
:beer:

[BAD MERC]

The only, I mean ONLY reason there are not 4:10's in mine yet - the installation cost will kill me.

[CodeMan]

I know it may be a little on the $$$$ side, but would a Ford, Lincoln, Mercury dealership be a wise choice??

Where I currently live, there is not to many quality choices of mechanics / technicians to do quality work, unless its at the dealership….wouldn’t dream of talking the Marauder to a “back yard” mechanic.

[babbage]

It's not that much. $260 is what I pay - out the door, make sure dealer has a pinon depth tool OR make sure the garage you take it to has done a lot of Ford 8.8's - you'll be fine.

(I supplied all the parts etc)

I'm putting 3.73's in mine. I want a little bit more but don't want the revs TOO high at 80mph. Stock is around 2400 RPM @ 80

[CodeMan]

Do you have any idea what the RPM will be @ 80mph with 4:10 gears????


This may be an issue for me, I travel long distances quite often. Towns are very spread out here in South East New Mexico. Its not uncommon to travel up to 85mph on the Hwy for 50+ miles just to get anywhere enjoyable.


Traveling back to Washington State within the next 6 months. Hope changing to 4:10 gears won’t “wind it up too tight” to enjoy on long journeys.

[SC Cheesehead]

Do you have any idea what the RPM will be @ 80mph with 4:10 gears????

You're looking at around 2,700 rpm at 80 vs around 2,400 - 2,500 with the 3:55's, not even an issue, IMO.

I've seen minimal impact on mileage as well, maybe 1/2 to 1 1/2 mpg at the most at highway speeds.

Do you have any speed shops that work on Mustangs in your area? They'd do a good job for you on the gear installation.

[Vortech347]

I cruise at 80 all day with 4.10's. The RPM difference is minimal and my MPG is BETTER with 4.10's than it was 3.73's.

Don't fear the gear, 4.10's or don't do it at all. The gain isn't worth the payment for the install. I did 3.73's but they were free.

seems the amount of time you spend on the highway 4:10's are not suitable for you. You say you would be driving on the highway ALOT in Mexico, I wouldn't advise it.

3:55 stockers are great for a nice conservative daily driver all around setup.

edit::3:73's is slightly more aggressive than the 3:55's and is very suitable for the strip and still suitable on the highways.

4:10s is Very aggressive gears MEANT for a track car (1/8 or 1/4mile) and NOT for a daily driver marauder that is MAINLY highway miles. ALthough many people here have 4:10's on a DAily Driver, it's most likely not suitable for your situation. It would be overkill for you to be driving 4:10's ESPECIALLY because you say you drive long highway distances to get ANYWHERE. Your'e engine would be constantly on high rev's and that wouldn't be good in the long run. You would be killing your car on 4:10's driving 85mph going 50mile+ distances constantly. I would even think for your situation specifically you should get a deeper trans pan from DR to give you 2 extra quarts of Trans fluid to make up for all that extra heat and rigorous running conditions.

This is all coming from my personal gearhead american muscle m.mechanic.

I was very interested in 4:10's and I still am. I'm iffy its either 3:73's or 4:10s.

Also he charged me 250 for the 4:10 install, but of course thats a "side job" and I know him because he said he would charge someone else 4-500. Also another mechanic friend of mine said he'll charge me anywhere from 350-400 and hes a general mechanic not specializing in american muscle like the other.

[CodeMan]

Thanks to everyone who gave their input!! Terrific points were put on the do’s & do not’s. I know for sure that more thought is going into this purchase before making a commitment. Thanks again!!!!
:woohoo:

[GetMeMyStogie]

The engine will rev about 15% higher with 4.10's compared to 3.55's

[Jolly Roger]

I think that if you're thinking 373's,
you might as well keep the 355's.

[Vortech347]

What are you smoking? We have 4.30's in our Cobra and have driven it cross country TWICE. Crusing at 85mph was around 3200ish rpm. We knocked down 26mph, that included the occational downshift to pass slower cars and a few 140mph romps. As for Engine life it put down 270rwhp on a loaded mustang dyno (most likely around 300ish on a dynojet) and it has 105k on the clock. Runs great!

The 4.10's Are just fine. I take frequent trips to following states for trips. The other thing you guys need to realize when dogging 4.10's is that Its no different than having 3.73's in a mustang. The tires on an MM are 27.5-28" freakin tall. There are SUV's that have that tire size and come from the factory with 4.10's!!!!!! Most mustangs/cars have 25-26. Infact the 4.10's in my car were out of a Ranger.

Don't spend the money on 3.73's. Get a tune instead, or Mufflers. I did 3.73's in an MM, the change was barely worth doing the work myself!

[babbage]

My issue Is I already have (in garage) the FRPP 3.73 "N" which use the nice new single pass face hob process. So I wanted to use them too.

Does anyone have a timeslip of an MM with 3.73 gears, CAI and tune?

Did you get a timeslip with your 3.73's? To see what the difference really is?

The odometer will be off too. Less miles and more revs does accelerate engine wear. I want my MM to be able to hit 14.4 14.5 ish in the 1/4

Is this possible with tune, CAI, and 3.73's?

[guccijayda]

Are you a cop? If no I was smoking a doobie. No j/k. Our argument is a very controversial topic. It's all a matter on how long you plan on keeping the car, driving conditions, reliability vs efficiency, daily driver vs track car, etc.

Of course it's not surprising that your car took a country trip TWICE, but lets just realize how much more stress there is on the drivetrain on his extreme conditions is very much a fact. This guy said lives he in a very isolated area in MEXICO and +85mph cruised 50+miles at a timeconstantly just to get anywhere would be considered EXTREME driving conditions with 4:10 gears.

Not really as extreme as you think. An MM with 18" wheels and 4:10's is like a Crown Victoria with 3:73's - Make sure to use a good fully synthetic rear gear oil. 75W-140 for the new mexico guy at 90mph...


An MM with 3:73's is like a Crown Vic with 3:55's - what I was thinking of doing. Worse case I can always swap in the 4.10's later.

[CodeMan]

Doing my research, and no matter how many times I look a the "pros & cons" of switching out from 3:55 to 4:10...:banghead:
I have my mind set on getting the 4:10's. If that means that I have to start taking it easy and keeping it at 65-70 mph on long trips....at least I can have a little fun when I get there :burnout:

[Dragcity]

I have been running with 4.10 for almost two years now. I drive my Marauder everyewhere, every day. I drive 100 miles to work, each way, often.

As you know, our engines like the higher RPM anyway. I only see over 3000 RPM when I stand on the go pedal.

If you are never going to supercharge, do the 4.10 and don't give it a second thought. I have over 40,000 miles on mine and have no regrets, other than I wish I did it before my warrenty ran out. It's been a better ride since.

[guccijayda]

I am also planning on getting the 4:10 gears although my driving situation is no where like new mexico, lol. I drive it as a weekend driver, not too much highway, rarely more than 65mph(speed limits here) granny style, but I'll push it once its warmed up occasionally :D.

It's not that I'm saying "4:10 gears are not meant for daily driving but just the track." I know 4:10 gears are suitable for daily driving as many of us do, but their are so many circumstances. Codeman, with your driving conditions, it's not surprising if your car performs flawlessly for a long time, but it's also not surprising if that weren't the case. Think about it, you can have two exactly identical brand new marauders, use the scientific method to obtain control, both cars have 4:10's one car has transmission problems at 40k miles, the other lasts 200k. I still believe running mainly long distance highway miles going 85+mph(ideal in New Mexico) daily is considered to be hard on your drivetrain with 4:10's. I had two panther p71's since I was 16. They can drive longer then you can stay awake on highways, they can idle forever, they can top out max speed for hours on end with no problems(what car you know that can tolerate that? Thats why police and state troopers use them for rigorous conditions and long endured high speed pursuits. Just if that was the case...


Codeman, Most of these people replying to you have very good knowledge and personal experience with 4:10's more than me. If you want your car to run 'forever', I guess you'll be fine with 4:10's as long as your not driving will ferrell style "your first or your last" all the time on the highway. Lol. 4:10s benefit the 1/4 and 1/8 mile, you'll loose more power after 70mph anyway. save it for the track! lol:banana2:

You may be surprised to know that in personal conversation with Steve Babcock, he stated that the MM was supposed to come with 3.73s or 4.10s from the factory, but was nixed by the bean-counters to avoid the gas-guzzler tax.

The ONLY downside to CodeMan running 4.10s in his situation will be a small decrease in fuel economy.

WHAT ARE YOU TALKIN ABOUT? I NEVER ONCE SAID " 4:10's are for the track, not daily drivers." READ THIS WHOLE THREAD, I even emphasized the fact that I never said that for people like you that misinterpret things. I'm fine with arguments and disagreements, I'm just not to fond of you putting words into my mouth.

This is EXACTLY what I said before.

"...NOT for a daily driver marauder that is MAINLY highway miles. ALthough many people here have 4:10's on a DAily Driver, it's most likely not suitable for your situation."

Codeman lives in New Mexico and said he drives constant long distance 85+mph which is not legal in most all states, it's actually considered very high speeds where we live, thats why i emphasized it.

[Dragcity]

What's 85 with 4.10 ? Must be somewhere around 2600 R's. I don't think that is "exessive" for these engines.

Whatever...

I agree that 3.73 would be a waste of time and $$$, even if the gears are free, the set-up will cost and there will be no benefit. 3.55 to 4.10 is not too steep a change.

Remember years ago, cars came with 2.73's. That would be a climb, but not with ours.

Dragcity, Out....

Yes I also realized that 3:73's are a waste after some experienced members chimed in. Well this argument was beneficial and controversial. Many seasoned mechanics will also state a mixed bag. Just like how some mechanics recommend transmission flushes and some highly advise not to use it.

I know there are much more experienced professionals with this car and I'm not one of them. I work in the tech shop of Darcars(mainly american), and I work as an apprentice for the head mechanic, and I learn alot from him. I do simple tasks such as oil changes, tires, helping hand, stuff of that nature. He deals with american muscle and many tuners come to him for serious tasks(countless stang's), although I would admit never with a Marauder. He has a borderline 5sec 1/8mile old school 5.0 mustang fully built with wheelie bars...I've seen pictures of the car almost vertical. I try to share some knowledge I recieved from him without jacking it up. Thumbs up to MM. members for having alot of experience with our cars which is a great advantage.

Please don't look down upon me and last of all don't put words in my mouth, I'm very open-minded to disagreements, but what your doing is just nonsense. I never went over the line, NEVER had an attitude, never looked down upon anyone for anything, my sole interest is me and my MM community. I just don't generate my self that way.

wow you take what i say and really jack stuff up:mad2: . Your really just trying to pick fights over your monitor?

Your really going to be this ignorant and put words in my mouth?

YOU TAKE a PIECE of my sentence and totally ignore everything else and tell me "THATS WHAT YOU SAID" It's either You have the knowledge of a 5 year old or your just so mad you have to make someone else look stupid by saying STRAIGHT BS and ignorance in english literature.

This is a Perfect example of how you take a piece of my sentence and try to make me sound like I said something else, when I clearly didn't.

"I like to kill police but only in the game counterstrike"

From that sentence you would tell me ,"You like to kill police? CAll the cops everyone now we have a cop killer!!!"

Your pathetic for trying to offend me and look down upon me when I was perfectly polite and never rude to anyone on these forums.

If your here to pick a fight, pick a fight with someone not behind the monitor please, or elsewhere atleast not here.



Everyone knows when they read all my posts that I never said it's not meant for daily driving period. There is such things called "conditions". Your'e getting real technical and putting things the wrong way...I stated on the same posts literally a sentence after that MANY members have 4:10's as a daily driver which is fine with no problems, and that I EVEN plan on running 4:10's and I made it clear that I "think" Codemans situation may be a little different however.

It's the people like you who mess up threads by starting fights on them for no reason. What do you call them "e-thug"? Please it's not necesary. If you think I'm saying something inaccurately then argue about it and say I'm wrong, don't purposefully look down upon me and put words in my mouth end ofs tory.

moderator or not doesn't have squat to do with how I react. He is the same as me. I don't need to look at him as a "god" just because he has the ability to ban me.

Read all my posts, I never gave anyone an attitude and was obsessively polite because I see how many posts get jacked and immature members START FIGHTS LIKE PIRANHAS. Many disrespectful things, but for the most part everyone is very helpful and nice.

I started the post of condition vs mileage thread. That is not solely for my benefit but for the whole community. I think of us as a 'family' or a "a teaparty for a special interest group" not as just a internet commerce. If he wants to ban me be my guest. I was always respectful to forum members and showed great appreciation and I deserve the same. I don't deserve that sarcasm and attitude, regardless of his status and power.

[Pops]

I read what RF saw and took it the same way. If any one is out of line it is you and your poor attitude. You are doing nothing but trying to pick a fight here. GROW UP and use some common sense. You deserve what you will get. You owe an apology and I am sure you are not enough of a man to give one!

[guccijayda]

yea everyone is biased. great. just because hes a mod. nice.I'm not surprised at all. And your a vendor?Great deal of sense. End of story I'm not even reading this post no more, send me a pm, ban me for all I care, as long as I'll know why you did it I won't look back. I was always considerate and respectful, I don't deserve that type of sarcasm and ignorance and arrogance, and putting words in my mouth, maybe a TAD bit unclear. This mod has "technical" a part of his name, I'm sure my english literary was off.

[Pops]

Make an apology and redeem yourself instead of coming on this site and picking fights.

Your insane. Why don't you do it for me, and suck his toes while your down there.

BTW: its not called picking fights, it's just that I'm not putting up with "being looked down upon" and a little something called pride. Sarcasm and arrogance towards me doesn't float my boat, oh on top of that ignorance. No reason to get all technical on me. I was always respectful. Maybe you should just mod the technical forums with him to attack people for using incorrect grammar and you'll sell some merchandise.

[imorb1994]

Its not due to the fact hes a moderator. Its due to the fact that he has helped a large portion of the members on this site in some way. With his knowledge, and generosity. Just sit back in the chair and relax. You keep talking about picking fights and thats exactly what your are doing right now.

Your talking about age?Well I put my age on there for a reason, I'm not scared to reveal it. I don't have to stoop down to your level to call you a "old bag" that just passed your mid-life crisis. I have more respect the nthat. Actually, my parents divorced when I was young, I'm sure some people here can relate to that and it's not something to be mentioned or joked about. I grew up working very hard, made all my own money, paid rent in my "father's" house, moved out with my friends, started my own ebay business, sold cars, sold anything I could, and look at me now a powerseller on ebay, I have a marauder and two other cars living decently enough.. I'm not rich, I just don't own my own property. Thanks. Ban me now moderator, oh excuse me "boss".

I'm sorry to most everyone other then this "tech-whore mod". I appreciated the rest of your help, it has been a pleasure. And you ask me to apologize when i was completely respectful and he was not? I feel like I'm at a office job getting bit**ed around by my boss.

Point simple and clear, I deserve the respect I give other people. I've been raised through hardship and independence. Sorry if I wont budge.

Thats nice. I see you still are not man enough to make the apology. You want respect then start giving some.

Well call me pigheaded. I'll probably install the 3.73's I have - along with a nice 28 spline Trak-lok that has been rebuilt by Dennis Reinhart with carbon fiber clutches, trick flow girdle, rolled spline dorman axles new bearings and seals all around -- and AMSOIL 75-110 (it's 'new') Gear oil.


$260 labor - I have the parts, except for the axles. Really I just want to replace it all before there is a problem (03 axle fail etc)

If I can go up a step with a gear set I have I'm doing it - unless someone sends me the 4:10's :D


I can probably leave the 3.73's in there if i get a trilogy kit later on correct??

seems like some work babbage.

guccijayda, I'm sorry if I came across as a sarcastic arrogant "tech-whore mod". I was just trying to inform you that many people on this board have installed 4.10s in their daily drivers and travel at highway speeds frequently, with no ill effects.

Truce?

Truce. I, by all means take back those harsh words as I wrote it out of a spur of the moment. I understand now your point and logic and I apologize as I know I over-reacted, especially being a newcomer on this site. Thanks

The wear and tear is not a factor. My wife spins our 01' with 4.30's at 3200rpm 20 miles each way to-from work and it has over 100k on it. Compression is great, RWHP and TQ are great. The gears were installed when the car had 12k on it.

4.10's are awesome in an MM. The RPM's might be a little higher but the other factor you're getting closer to peak torque so you'll be working the engine LESS actually.

I do have timeslips from my 3.73's in my old car. 16.2 stock gears and superchips tune. 15.9 with 3.73 gears and DR tune. It wasn't a very good gain which is why when it came time to do it again I did 4.10's. And next time? 4.30's for sure.

One of the key points of 4.10's working so well is the fact that we're driving heavy cars. More mechanical advantage = less load on the motor. The extra RPM is negligible to these motors, they were built to rev high.

Kieth you too have 4.10's installed?

[Bradley G]

Expect to be a little quicker off the line than your Non 4:10 equipped Marauder Brotheren.
If you raced them to their non governed top speed , you W/ 4:10s' would get passed @116.329 mph :D

WOW...Nice to see this thread get back to the subject,We are all her to help each other...right?

Yeah thanks for de-railing again. :banana2:

I'm going to install my 3.73's

Yes, I've had them in for over 2 years now. Been daily driving it on the highway 50km a day, summer and winter and haven't had a problem. Fuel mileage may have dropped a bit on the highway <1mpg, but it picked up in the city as it doesn't take much effort now to accelerate with the flow of traffic. I also installed a Trilogy supercharger a couple of weeks ago, so we'll see where the mileage ends up.

What is everyones opinion of BFG Tires?

JK.....

Man that was a painful thread to read......It was like watching (reading) a chick flick!

I bought 4:10's and a tuner and am looking forward to joining the crew in experiencing how a Marauder is supposed to feel/respond .... All based on what I have read on the MM site...I would be "lost" without you guys!

Going with the ZACK Tune :banana: and it's my daily driver!

Many of us with Trilogy's don't really see the need for anything other than stock. I may or may not upgrade down the road but all is GREAT for now.:cool:

[PonyUP]

I don't know much about cars, some would even question I know how to drive them. But everything I have been told says a tune and gears are the most affordable mod's and make a big difference. If shedding the green is a concern and you can't go for the super charger but you want to haul a$$, it's the way to go

^^^^^very smart choice if wanting instant gain over stock.^^^^^
