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

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 1975 Buick Apollo Base 1975 Buick Apollo SR 1975-1977,1980-1981 Buick Century Base 1975-1979,1982-1989 Buick Century Custom 1980-1981,1984 Buick Century Estate 1985-1989 Buick Century Estate Wagon 1976 Buick Century Indianapolis 500 Pace Car 1978-1989 Buick Century Limited 1975 Buick Century Luxus 1984 Buick Century Olympia Limited 1975-1979 Buick Century Special
