Powertrax Spring and Pin Kit for Differential Lockers

Powertrax Spring and Pin Kits are genuine OEM-specification replacement components engineered to restore and maintain the performance of Powertrax automatic locking differential systems. Springs and pins are the mechanical heart of every Powertrax locker — the components responsible for consistent engagement, reliable torque transfer, and smooth disengagement during cornering. Whether you're performing routine preventive maintenance or a full differential rebuild, these kits supply the critical internal hardware your locker depends on.

Understanding why these parts matter is straightforward: springs ensure the driver re-engages with the coupler after exiting a turn, while pins couple the two drivers together to transmit torque during locked operation. Over time and under demanding use, springs can lose tensile strength and pins can fatigue — and when they do, locking performance suffers before visible damage ever appears. Proactive replacement is the most cost-effective way to keep your Powertrax locker performing as designed.
