This spool is designed for use in 2015+ Dodge Challenger ZF rear differentials, providing a fully locked differential for maximum power transfer to both rear tires.

Unlike a limited-slip differential, a spool permanently locks both axles together, eliminating differential action and ensuring equal torque distribution under acceleration. This makes it an ideal solution for drag racing and other applications where maximum traction and consistency are required.

Manufactured from high-strength materials and precision machined for proper fitment, this Challenger spool is designed to withstand the demands of high-horsepower Mopar applications. Installation is straightforward using standard differential setup procedures.

Built for racers and performance enthusiasts seeking the ultimate in traction and drivetrain consistency.

This item is proudly designed, engineered, and manufactured in house at IMS.
