Chevrolet GM 8.6" Free Parts Illustration

8.6 gm rear end parts

Whats the difference between gears with and without ABS?

ABS rings gears have a back cut/clearance that the "without" gears don't have as the ABS reluctor wheel requires additional space, where the reluctor goes right behind the ring gear.

Customer recommends American Axle ring and pinions and setup advice: "You will not regret this choice...gears are not a good place to cheap out and the GM gears really are made and finished a lot better. Note that these run extremely tight backlash .004"-.007", shoot for .004"." See image below for what the pattern looked like during trial settings and the final pattern.
