Info

Speedway Motors offers these clutch operated posi-traction differentials as a welcome alternative to locker & spool differentials which are often overkill and more expensive than the common street car requires.

Based off of the original limited slip designs of the OEMs, these differential units provide the added benefits of millions of miles and decades of proven reliability.  Speedway has taken this engineering to the next step in performance with increased clutch pressure and holding power, suiting it well for heavy duty street car applications.

  • 28 spline
  • Clutch style, spider gear differential = proven reliability
  • Forged steel case
  • Heat treated spider gears
  • Quiet operation, no clicking when disengaging for corners
  • Spring loaded clutch pack with improved grip over OEM designs
  • Proven reliability and Economical design
  • Works with factory 9” ford differential case, gear, axles and bearings
  • Ideal for Street tires and medium horsepower applications

This differential has performed well in our Week to Wicked 1952 Chevy Truck, handling the job of transferring a 430 HP GM Performance LS3 to the ground. Speedway Motors continues to bring quality products at an affordable price to keep your project on the road and the race track.

*Racing applications with 10.5” tires, drag radials or slicks are better suited for the more expensive locker and Powertrax style carrier designs.
