AAM ring and pinion gear 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. Our innovative "Two-Cut" manufacturing process ensures the lowest tolerances possible for the quiet operation required by our OEM Ring & Pinion customers. This "Two-Cut" design also allows for easier set up in the aftermarket replacement business. The combination of materials, heat treating and cut geometry allows for a gear set that has ten-times the life of a non-OEM Ring & Pinion gear set.
