Traction-LOK Limited slip differential (posi)


This kit is a direct replacement for the OEM clutch set. It doesn't require any modification. It provides 3x more grip than the factory set due to much higher friction coefficient! With superior longevity, you won't have to worry about changing this set ever again!

Fits Ford 8.8 inch Traction-Lok Limited slip differential (Posi) unit found in Mustang (1985-2014).

Why to buy RacingDiffs Clutch stack? 

  • 1. Improved friction coefficient
  • 2. More grip
  • 3. Increased diff lock
  • 4. Better durability
  • 5. Less wear
  • 6. Enhanced heat resistance


The solid plate construction will prevent the lift-off of the friction layer, which is the most common problem with the OEM plates. The Molybdenum-Ceramics friction layer is the most advanced friction coating that provides the optimal friction coefficient and wear resistance ratio. 

*All parts fits OEM Mustang LSD unit without any modifications.

RacingDiffs Recommends Motul Gear Competition 75w140 oil for all products.
