Spicer Trac-Lok Limited-Slip Differential Clutch Pack Kit for Chrysler 8.25" Rear Axle (Dodge 29 Spline)

Eliminate frustrating rear-end tire slipping, correct aggressive differential chatter, and restore factory-spec dual-wheel traction with this genuine Spicer Trac-Lok Clutch Kit. Specifically packaged as a comprehensive internal rebuild solution for Chrysler 8.25-inch 29-spline rear axles, this premium package replaces the worn friction discs and steel plates inside your factory limited-slip differential (LSD).

On high-mileage Dodge Dakota pickups, Durango SUVs, and Jeep Cherokee XJ models running the popular Chrysler 8.25" rear end, the factory Trac-Lok differential relies on a stacked sequence of alternating friction discs and steel plates to distribute engine torque evenly to both rear tires. Over time, continuous heavy towing, high thermal cycles, or aggressive off-road use naturally wears away the specialized friction material. When these internal clutches wear down or smooth out, your differential reverts back to operating like a standard open unit—leaving you stranded with a "one-wheel peel" when accelerating on wet pavement, ice, or loose trail dirt. Conversely, degraded or broken clutch tabs can cause the rear end to bind, chatter, or groan loudly during tight cornering.

This original equipment manufacturer (OEM) restoration package includes a complete, factory-sequenced array of premium multi-lip friction discs and precision-ground steel plates to fully rebuild your Trac-Lok carrier. Sourcing a genuine Spicer component ensures exact original equipment stack thickness, correct splined tab engagement depths, and highly durable friction scoring engineered to work flawlessly with your vehicle’s factory axle shafts and gear oil chemistry.

Installation Note: For optimal performance and quiet operation, always pre-soak the new friction discs in premium limited-slip gear oil additive (friction modifier) for at least 20–30 minutes prior to internal carrier assembly.

Kit Contents:

• Complete Stack of Premium Trac-Lok Friction Discs (Inner Splined)

• Complete Stack of High-Tensile Steel Plates (Outer Tabbed)

Kit Highlights:

• Restores Positraction Power: Re-establishes correct spring-loaded preload friction limits inside the carrier, ensuring power transfers seamlessly to both tires instead of spinning a single wheel.

• Genuine Spicer OEM Engineering: Formulated by the premier original equipment drivetrain supplier to match exact factory thickness tolerances and structural steel tempering limits.

• Cures Turning Chatter: Replaces warped plates or stripped friction discs to eliminate binding, popping, and groaning noises during low-speed cornering maneuvers.

• Heavy-Duty Friction Compounds: Utilizes advanced, high-coefficient wear materials designed to withstand immense torsional heat build-up from commercial hauling and large tire leverage.
