Eaton 31 Spline Posi Limited Slip Differential for 8.8" Ford Rear End

The Eaton Posi LSD is the perfect way to control traction in street rods, light duty pickups and all types of tarmac running race cars. The Eaton Posi LSD prevents wheel slip before it can get started. To do that, carbon disc clutch packs, preloaded by a central spring assembly, are located behind each differential side gear. When torque input increases the clamping load on the clutch packs increases. That causes the chatter-free clutch packs to grab and transfer power to the other wheel. Muscle cars, hot rods and mild off-road vehicles should look to Eaton's limited-slip differential for their traction answers. And the fact is, Eaton's Posi units are virtually bullet proof. Note: Requires 31 spline axles. Application: 1986-1998 8.8" rear ends
