Product Description

AAM (OEM) 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.

Eaton Posi LSD

The Eaton Posi limited-slip differential prevents wheel slip before it can get started. To do that, carbon disc clutch packs, preloaded by a central spring assembly, are located behind each differential side gear. When torque input increases the clamping load on the clutch packs increases. That causes the chatter-free clutch packs to grab and transfer power to the other wheel. Muscle cars, hot rods and mild off-road vehicles should look to Eaton's limited-slip differential for their traction answers. And the fact is, Eaton's Posi units are virtually bullet proof.​

Recommended oil is standard 80/90 weight (non-synthetic) (with posi additive).

Master Install Kit

Premium master install kit uses only the highest quality components including Koyo brand bearings. Included are carrier bearings and races, pinion bearings and races, pinion seal, complete shim kit, ring gear bolts, pinion nut, crush collar, threadlock, marking compound, brush, and gasket or RTV silicone.
