Hey guys, a while back I had a call responding to an ad I placed looking for a 3.23 or above rear axle for my IROC. Cutting a long story short, went to pick it up and found the calipers on the axle are finned, also I'm sure I counted 9 bolts..... Have I unearthed Gold here, or amI just getting over excited?

1LE's have the same rear axle as every other 89-92 TPI car... What year is it from?

Difficult to tell as the car itself wasn't around. He told me an '85????

 

They didn't even have 1LE's back in 85. That rearend is probably just a 9 bolt Borg Warner with PBR brakes off an 89-92 car.

 

So just how good is a Borg Warner unit? Bullet proof??

It's better than an F-body 10-bolt, but not as bulletproof as a 12-bolt or 9".
