rear end which one

[mercmatt]

im going to get 4.10s over the winter and i know dennis sells the fms ones but what about auburn and eaton diffs? just looking for a little info from people who have experience with the different types of diffs. (price, reliability, where to get them)

There ok but they can be more prone to noise that is why I use FMS

Are you aksing for what brand of gears or differentials?

 

[CRUZTAKER]

Indeed...

Why replace the LSD if it ain't broke?

If you have a big wallet and just don't g-a-s.....

Get an EATON LSD with your new FMS gears and...


BOOYA! :up:

 

[mercmatt]

i thought gears and diferentials were the same thing

'Gears' (ring gear...3.73, 4.10, 4.30, etc.) get bolted onto the differential (FMS, Eaton, Auburn, etc.) which mounts inside the rear axle housing.
The matching pinion gear gets bolted into the front snout of the axle housing.

I recently checked with a local speed shop about gear upgrades, they had a strong preference for the FMS gears. In addition to mentioning noise issues with other brands, they even called some of the other brands "crap". Since I intend to keep the MM indefinitely, and the wife drives it a good bit, I will gowith the Ford gears when I am able to get them done. The MM is our "everything" car, so I need something rock solid for the long haul. If it was used only for fun then I could entertain other gear options.
