Spicer Trac-Lok Differential Clutch Pack Kit for Dana 44 & Chrysler 9.25" Limited-Slip Carriers

Restore factory traction capabilities, eliminate rear-end chatter, and rebuild your limited-slip assembly with this genuine Spicer Trac-Lok Differential Clutch Pack Kit. Over years of service, the friction materials within a positraction carrier naturally wear down, causing the internal spring preload to drop. When this happens, your vehicle loses its limited-slip capability and reverts to a standard open differential—leaving you stranded with single-wheel spin in mud, snow, or loose trail dirt.

Failing or worn differential clutches will often present themselves through a noticeable "chatter," binding sensation, or mechanical groaning when making tight turns at low speeds, or a complete loss of power distribution to the tire with traction. Replacing worn plates with this genuine original equipment manufacturer (OEM) kit restores the precise stacking tolerance and friction coefficients required for smooth engagement.

This complete master rebuild bundle includes 8 premium steel clutch discs and 10 structural plates crafted to handle high torsional loads. Because Dana and Chrysler corporate engineering cross-pollinated extensively across classic trucks and SUVs, this exact kit serves as the factory-correct service solution for both Dana 44 Trac-Lok assemblies and Chrysler 9.25-inch corporate limited-slip rear ends.

Kit Highlights:

• Complete Overhaul Contents: Contains 8 premium steel clutch discs and 10 structural matching plates to completely refresh both internal sides of the limited-slip carrier.

• Genuine Spicer OEM Quality: Manufactured by the original equipment supplier to guarantee matching steel hardness, friction tolerances, and exact stacking height metrics.

• Restores Positraction Power: Restores proper internal spring preload, forcing the side gears to distribute torque evenly across both wheels under low-traction situations.

• Eliminates Low-Speed Chatter: Engineered with high-grade steel to deliver smooth, quiet slip characteristics during cornering when combined with quality gear oil and friction modifier.
