AC and master cylinder

[sflrainmaker01]

So, next week I am getting the car supercharged. The deal we made included him installing a new AC compressor (the ac works, but when the compressor is on, it sounds like a Mack truck) and master cylinder (leaking). My question is does anyone have any recommendations as to what brand to use for either part? I saw the Motorcraft brand compressor at Rock Auto for $369, which was double the no name remanufactured ones. Although it said "new".

OEM.......

You should go oem like MuscleMerc says also the aluminum accumulator and orifice tube.

Do you still have the 4:30s in that car?

Actually, they are 4:10's. The P/O wasn't for sure. I thought they were 4:30's
until I checked it out myself. I just forgot to update the sig.

Motorcraft on both counts.

I agree with above and use OEM. Those parts aren't replaced that often so whats an extra couple hundred bucks.

Hmmm...I was looking at replacing the 4WD transfer case motor on my Ranger a few years back when it stopped working. The Dorman part is identical to the Motorcraft part at about a third of the price and Dorman is a supplier to Motorcraft (and others). Mechanic/Shop Owner (ex Ford Tech) ended up rebuilding it for $50.

For what it's worth.

I’ve had 4.30’s when mine was an auto w/Trilogy. Both them and 4.10’s are good street gears to keep out of boost and still pull hard, but not too much on launch with decent tires or highway RPMs. Not much of a difference really between them.

I have heard of Dorman. When I was redoing the motor on my 86 GT a few years back, I went through two "rebuilt or remanufactured" distributors only to have both fail and the last one left me stranded on the road. So, I opted for the more expensive but more reliable MSD NEW distributor and it has been awesome since. So, I don't want to have to spend more than I need to on these parts for the Marauder, but, I don't want to have to mess with them again! At Rock Auto, there is no "Dorman" or the like that I have heard of for the replacement parts, However, they do have a replacement AC compressor that is Motorcraft for about $50 dollars less than the Ford dealers I have checked with, including White Lake Autonation etc.

Dorman is OEM - I won't insult your reading comprehension.

[fastblackmerc]

I won't use Dorman parts for anything that is related to safety or drive-ability.

Too many horror stories and my own experience.

Anyone remember the "thermal" events with Dorman radiator fan assemblies?

Dorman is OEM - I won't insult your reading comprehension.Do you have any proof Dorman is OEM for Ford, or any examples of which parts?

[Grimrepairman]

90% sure dorman is strictly aftermarket.
Some of their stuff is great, some either doesn't fit or fails in record time.
I reccomend oem unless you absolutely cannot afford it. Or unavailable.

Nothing other than what my tech stated. Are they not?

From their website:

A play on words? If I'm wrong I certainly apologize. All this time I thought Dorman was an OEM supplier.

Dorman Products is a leading supplier of original equipment dealer "exclusive" automotive and heavy duty replacement parts, automotive hardware, brake parts, and fasteners to the Automotive and Heavy Vehicle Aftermarkets. I'm not saying you're wrong, but that statement is somewhat ambiguous. What exactly is an "original equipment dealer exclusive replacement part"? Does that mean some parts in Motorcraft boxes are actually supplied by Dorman? At this point I agree with Grimrepairman: Some of their stuff is great, some either doesn't fit or fails in record time.

I’m wondering if the stuff that passes inspection goes out the door in Motorcraft packaging while everything else (including surplus) goes out the door in Dorman packaging?!?! Scary thought LOL!!! I suspect Dorman supplies multiple manufacturers besides Ford. When I had the instrument cluster in the Mustang rebuilt years ago I was told the same vendor built clusters for multiple manufacturers and they all experienced identical failure rates back during the mid 2000s (stepper motors?).
