Well suspensions comin.. now im onto the drivetrain..

Is there anything i should order other than the "Ford Racing 3.73:1 Ring and Pinion Set - For 8.8 inch rear end"? or when i get it installed wil the shop have everything?

do you think im wasting money going for the 373s.
i felt i would get them because
i am probably s/c in 3-5 months. i like driving at a high top speed.. freeways, and streets + car is a 3-5 day driver.. during the week.

on top of this i have been told to get my clutch installed before installing lt's. why? idk it makes it easier? is this true or not.

Master Bearing Kit + Gears + Hope you have something to tune the computer for gear changes.

The gears will actually make you clutch last longer... It takes alot less effort to turn 3.73's then it will stock gears...

I keep seeing people saying you "HAVE" to have a tuner for gears... My speedo was only off by a little bit, it's not a muct, but it will add mileage...

My kit did not come with a crush sleeve. FYI. When you get it make sure it is there.

can someone explain to me the eaton posi? and do i need to get the motive bearing kit?

master bearing kit is cheap insurance. i HIGHLY recommend it.

Eaton posi is a limited slip differential it eliminates the 1 wheel burnouts. It forces both wheels to spin at the same rate with limited slippage.

as for the clutch some may need 500 miles or so to break in properly. My Spec stage 3 was that way. I had the sme thought s on the gears 3.73 or 4.10. I went with the 4.10 and ave no regrets. 70 mph is about 2400 rpms.
