4:10 rear end

[johnanthony]

Can anyone suggest a St. Louis area shop that can upgrade
my Marauder from 3:55 to a 4:10? About what is a fair price?

PM 1stMerc, Bodyman, or Buckwheat, they may be able to help you out.

Check with the local Mustang clubs. The 8.8 rear is the same.

I also live in the st louis area. Let me know. I hear Craven Automotive is one of the best around. Google it.

ok will do in the morning

[kingace]

just bought a marauder.. how would i go about finding out wich i have a 3.55 or 4.10

[bolsen]

You'd know if you had 410s. I believe jack up the rear end and 1 full spin of your tire should turn the drive shaft 4 times. Easiest way to know for sure.

[JoeBoomz]

If you're at 2500RPM doing 75MPH you have 4:10's.

[kingace]

ok pretty sure i just have the 3:55, how can i convert it to the 4:10?

[jstevens]

You can just hook up with Alternative Auto. I think in Chesterfield.

You'll have to purchase the gear set and have it installed by a professional.

[MOTOWN]

Dont forget drive train specialties on groobeck in warren they get $300 for the install plus any parts

[kingace]

awsome thanks guys...

He's going to need a tuner as well to fix the shift points and speedo. Lido at Alternative can hook him up here as well.

[kingace]

How much do tuners run...for a good one

[Mr. Man]

Get in touch with Alternative and let Lido know what you want or are going for. SCT 3 are like 380 if memory serves. Believe this includes the tune but would double check on that.

[RF Overlord]

Lidio......

[kingace]

Ok ill do that...I also her with the 4:10s if kills your engine and transmission life..is this true

[jstevens]

Not true at all. 4.10's are a blast. They were on my DD that had nitrous.

[Mr. Man]

Generally no, but the 4.10's will make your car more zippy so if your prone to a heavy foot maybe but that would also kill a 3.55 rear too.:burnout:

[RF Overlord]

I also hear with the 4:10s it kills your engine and transmission life..is this trueYes...if you're talking about a 1970 Torino with 14" wheels. You need to talk to people who's knowledge has been updated in the last 40 years. ;)

haha alright awsome thanks guys!!
