Spicer Trac-Lok Limited Slip Differential Clutch Pack Kit for AMC Model 20 Jeep Rear Axle

Restore factory-certified traction, eliminate aggressive drivetrain chatter, and rebuild your classic limited-slip differential with this genuine Spicer Trac-Lok Clutch Pack Kit. Specifically engineered for Jeep vehicles utilizing the AMC Model 20 round-bottom rear axle, this premium factory service bundle contains all the internal friction plates and steel discs required to fully overhaul your original Trac-Lok carrier.

The AMC Model 20 rear end was a staple of vintage Jeep performance, but decades of hard trail driving, oversized tires, and highway commuting wear down the internal differential clutches. When these plates wear down or lose their mechanical preload, your Jeep will suffer from single-wheel slippage ("one-legged" power delivery) or develop harsh binding and metallic popping sounds during tight turns. Rebuilding the carrier with this genuine Spicer package restores the progressive power transfer needed to safely conquer loose dirt, rocks, mud, and snow.

Kit Highlights:

• Complete Internal Overhaul: Includes a full sequence of premium inner friction plates and Tabbed steel separator discs to completely rebuild a single factory AMC 20 Trac-Lok carrier.

• Genuine Spicer OEM Quality: Precision-stamped from premium-grade steel alloys and layered with specialized friction materials to withstand severe off-road heat cycling.

• Eliminates Axle Chatter: Corrects internal stack-up clearance tolerances to stop low-speed tire skipping and drivetrain binding during tight turns.
