Detroit Truetrac - Chrysler 8.25 29-Spline

The Detroit Truetrac for Chrysler 8.25 29-Spline is a high-performance limited-slip differential engineered for drivers and mechanics seeking reliable traction without the complexity of electronic controls or aggressive locking behavior. This differential excels in street and light off-road applications where consistent power delivery and cornering stability matter equally. Whether you're upgrading a Dodge Dakota, Jeep, or other Chrysler 8.25-equipped platform, the Truetrac delivers torque biasing that keeps both wheels working together under acceleration while allowing natural wheel speed differentiation during turns.

The Truetrac uses Detroit Locker's proven clutch-pack design and helical gear geometry to eliminate the dead-hook harshness of full lockers while maintaining superior traction over open differentials. The 29-spline count matches OEM Chrysler 8.25 applications, ensuring perfect compatibility and eliminating the need for custom axle modifications. Internal components are precision-hardened and finished to withstand daily driving stress and repeated power cycles. At 22.7 lbs, this unit integrates seamlessly into existing housings, and the compact 8.2 x 8.1 x 8.9-inch footprint confirms original fitment without adapter rings or modifications.

Technicians and enthusiasts favor the Detroit Truetrac for Chrysler 8.25 29-Spline when factory open differentials prove inadequate for towing, hauling, or spirited driving. Installation requires standard differential service procedures—no special tools beyond basic axle work are necessary. This differential is compatible with OEM ring-and-pinion gears already in the housing, making it an ideal bolt-in upgrade for Dana 35–based Chrysler rear axle assemblies. If you're rebuilding a 1990s–2000s Dodge pickup or Jeep platform and want tangible traction gains without full electronic locking, the Truetrac delivers proven durability and balanced performance.
