8.5 rear out of an S10

[mebe007]

ok i am an owner of a 2003 s10 zr2. just to let you know the ZR2 is the only s10 to come with the 8.5 rear. it also came factory with 3.73 rear gears. in addition to this the zr2 has a wider trac width than the standard 4x4 and 2wd s10's. also since it is 4x4 it has beefier axles and of course since the year it is 30 spline axles i think and also comes with the g80 locker unit. the zr2 s10 is also a little rare, and is extremely hard to find in a junkyard.

but the S10 axles already have the same bolt pattern then us ...5 x 4.75

the ford axles have to be modified cause originaly they are 5 x 4.5

I may be wrong but one of the guys at our shop has a 4x4 s10 and he said the bolt pattern is the 5x5 not 5x4.75 like the 2 wheel drive.

I'll have to measure his next time I'm at the shop. His is the previous generation s10.
We were talking wheel swaps tonight and thats how it came up.

Nice looking truck by the way

94-2003 are all the same, check out www.zr2usa.com. also i believe the 80s models to be 5x4.75 as my friend had corvette rally wheels on his.

Pretty sure like every rear wheel drive GM vehicle has the same wheel stud dimensions when it comes to the bolt pattern 8)
