Product Description

AAM Gear

American Axle & Manufacturing (OEM) ring and pinion sets are uniquely designed to match the requirements the OEM Ring & Pinion designated for your specific vehicle. All performance factors for the size and weight of the specific vehicle must be taken into account. Only original equipment quality components are guaranteed to meet the same specifications as the parts they replace. AAM components mean performance to the vehicle manufacturer's standards. The combination of materials, heat treating, and cut geometry allow for a gear set that has ten times the life of a non-OEM ring and pinion gear set.
