Eaton Posi Differential 28 Spline 1.20in Axle Shaft Diameter Rear 8.8in

The Eaton Posi limited-slip differential 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 Eatonss limited-slip differential for their traction answers. And the fact is, Eatons Posi units are virtually bullet proof.This Part Fits: Year Make Model Submodel 1986-1997 Ford Aerostar Base 1988-1994 Ford Aerostar Eddie Bauer 1986-1994 Ford Aerostar XL 1989-1994 Ford Aerostar XL Plus 1991-1994 Ford Aerostar XL Sport 1986-1997 Ford Aerostar XLT 1989-1997 Ford Aerostar XLT Plus 1991-1997 Ford Aerostar XLT Sport 1994-1997 Ford Aspire Base 1994-1995 Ford Aspire SE 1983-1993 Ford Bronco Custom 1985-1996 Ford Bronco Eddie Bauer
