Default my beefy 10 bolt build...(W/pix)

If you cant call it a beefy ten bolt, I'm sure you can classify it as some kind of meat product....

Parts list:

precision 3.73's
factory auburn with ARP ring hardware (ebay $275 w/30k)
USA alloy axles (net $160 shipped)
MAC rear cover (WS6 store $138)
Raytec solid crush sleeve ($22)
ARP cap stude kit (thunder racing $28)
ARP 3 1/2 wheel studs (net $65)
oil, additives, new pinion bearings, paint $130 est

these are all est prices i don't know exactly what I paid in shipping. Honestly I like to forget about how much I pay for performance parts...

First i pulled the whole POS. it was getting a little too noisy, and the diff sounded like I had a bag of rocks in the posi.


I always thought it lame that the factory didn't coat their rear ends with some kinda paint. mine had 80k on it and looked like ****.


It's a pretty good pattern for a set of used gears, I reused the new/used carrier bearing but switch to a new set of koyo on the pinion. The original timken front pinion bearing was toasted.9making my noise) set backlash to .008


set up with all the ARP goodies


when it came to installing the rear cover i ran into clearance problems between the cap studs and inside lip of the cover. Only toke a couple of minute to fix though.


As posted before the hardware that MAC provides is a 1/4in too short.(lame)
I used my drill press to fix this. using a 3/8 bit to center each bolt hole i lock down the cover in place. Then I would then switch to a 1/2 bit to to deepen the counter sinked bolt hole.


All done after hours of cleaning and building




I think wheel studs on a car just look sexy


All in all a great mod. going from a 3.23 to these 3.73's isn't a huge jump but enough to justify it. The car feels great and doest dog in forth anymore. the gears are dead silent until about 75mph. I can hear a slight howl but only if the windows are up, the cut out is closed, and the radio is off. but who drives like that anyway??

est total spent: $820ish not bad!

Looks really good. That must have taken a long time to clean all that grime off before you painted it.

Nice build and cleanup. To give it a little bit more strength you should have welded the axle tubes to the housing. It may not have helped any but couldn't hurt.

a little simple green soak, a wire brush, and a lot of quarters at the car wash is all it toke....

Not really on a torque arm set up. Only if the rotational load is outside the center section.

i agree.. if it was a leaf spring car I would have...

I like to think of it as a calculated risk. At this point the weakest part of the setup is going to be case distortion witch would lead to pinion bearing failure. if this happens I wont hesitate to slap a new front bearing in it and call it a day. still cheaper then a $2500 9in. i know not as strong but still strong enough..

i run a 6in DOT slick, with 70% of the weight of the car in the rear it hooks well. best 60ft is 1.47, hanging the wheels for most of that
