What does everyone recommend for a differential and axles. I plan on going with 31 spline. I use the car primarly for street driving and hit the 1/4 mile almost every weekend.

I've seen Eaton posi, auburn, etc. What does everyone recommend. Also, when everyone upgraded their axles, did you do the c-clip eliminators or remove the traction control??

Thanks;
Mike

I posted a thread a couple days ago asking what was required to the the rear end upgrade. If you chech the last couple pages of this forum, you might find it under "rear end questions". Some replied with their suggestions...It's always good to hear other opinions, though!

If you do C clip eliminators, you loose your ABS. As for what brand, Auburn makes a good unit as well at Eaton. 31 Spines are in my future plans so Im anxious to hear some info as well .

If you're going to the strip every weekend a spool or mini spool might be best for less money. Just can't get as nuts around the corners.

the Auburn is garbage, you'd grenade it on DRs before you know what happened.

the Eaton/Superior package from DTD is a good deal. its like $559 for the diff, axles, axle bearings, axle seals, and (useless with Welds) stock length wheelstuds.

a spool is over kill unless you launch at 6k+ and your willing to lose the ABS. if you launch at 6k+ and you want to keep the ABS get a Detroit 'C' Locker.

I asked them about this a month or so ago, and they said they do not offer any such package deal. Here are the prices that I got from them over the phone(http://www.drivetraindirect.com/)
Eaton $389
Superior Axles $279
Superior Install Kit $80
==>Total $748

I found a price of $360 on National Drivetrain's website(http://www.nationaldrivetrain.com/) for the Eaton.

Summit Racing seems to have the best price on the Superior Axles and Install kit, $250 and $70 respectively.

Gene Evans Ford (http://www.gefracing.com) has the best price on FMS gears at $140 and the FMS aluminum driveshaft $148.

Here are the manufacture product numbers in cases you guys want to cross reference them.

Superior Axle Kit (31spline): EV84
Superior Master Overhaul Kit: 35-2013
Eaton Differential (31 spline): 19588-010

They may /must not offer it any more. At the time they said you could have Eaton or that other hunk of junk with you package...
agree with GEF...
also another source for eaton at $360 is

http://www.macromotive.com/shopping/goShopping.cfm?tag=3.5.410801.0.4433.0
Mustang 35...you can rrebuild the Eaton...making it popular...its strong too.
the auburn breaks and goes in the trash can. I'd run a FMS 31 spline truck diff before the Auburn. They are much stronger than stock, are rebuildable, and are cheap...at GEF too. I know several cars running 9's on that FMS piece with double clutch packs..

Dave, at the ETs and Speeds you car is capable of you need the long studs and open lugs to be legal (front and rear). if you track is lax in tech then you may get through... if you want to run FFW or NMRA, you'll flunk and go back on the trailer until you fix it.

Slider, tell them you saw the ad in Fastest Street Car magazine.

hehehe I guess I better get it fixed then...going to Atlanta in Mar and I dont want that. I knew about the rear but I thought the front they just wanted to see the stud so I could knock the cap off. I guess I need to go to school on this ASAP.
I'm trying to find a way to be able to still run my stock wheels but that would take deep stock lug nuts???
Thanks Mike

I just checked with drivetrain direct again, and they qouted me $738 this time.

Eaton $342
Axle $308
Inst Kit $88

Well, that means they have the best price on the Eaton by far, but Summit Racing still has the best price on axles.

I'm probably going to go with the Eaton Posi unit with 31 splines. That should take a good beating at the track and on the road.

Thanks for all the help.

GI Joe;

Why do you say not to go with c-clip eliminators? I know you lose ABS, but what else is the problem?? Also, once the ABS is gone, is there any way to clear the dash ABS light???

Sorry, Read "don't go" instead of "did not go". I guess the proper question is why not then?
