The 8.5-inch is often referred to as the "GM corporate 10-bolt" because of its multiple uses, and the 8.5-inch is a semi-float axle, meaning it has only one axle bearing per side, mounted inside the axle tube. The reliability of the axle tube and bearing are really the only problem spots you are likely to encounter with the 8.5-inch rear end. The axle tube is thinner (.3125-inch thick) than that in the 12-bolt, and the axle bearing is probably the weakest link of this rearend assembly.

Ten Factory have a 10 Year warranty on all thier shafts.

Nitro Gear has a Lifetime warranty on all thier shafts.
