Eaton Posi Differential 33 Spline 1.37in Axle Shaft Diameter Front 9.25in Rear 9.5in

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 1988-2005 Chevrolet Astro Base 1988-1995 Chevrolet Astro CL 1988-1995 Chevrolet Astro CS
