Description

The AAM 40070463 is an OE ring and pinion gear set designed for GM 10.5-inch, 14-bolt rear ends. This set features a 4.10 gear ratio and utilizes AAM's innovative "Two-Cut" manufacturing process. This process ensures low tolerances for quiet operation and easier setup in aftermarket applications.

The combination of materials, heat treating, and cut geometry in this gear set provides a lifespan ten times longer than non-OEM ring and pinion sets.
