Eaton Posi Differential 26 Spline 1.16in Axle Shaft Diameter 3.23 & Up Ratio Rear 7.5in

Take control of your vehicle's traction with the Eaton Posi limited-slip differential. This unit is designed to prevent wheel slip before it starts, using carbon disc clutch packs preloaded by a central spring assembly. As torque input increases, the clamping load on the clutch packs increases, transferring power to the other wheel.

  • Tunable via various spring packs (pre-loads)
  • Pyrolytic Carbon Clutch Disc Technology for smooth engagement
  • Clutch Type Limited Slip Differential for automatic operation
  • Precision-Forged Gears for added strength
  • Rebuildable design for long-lasting performance

This product fits more vehicles than loaded. Please select your vehicle to see all fits.
