Eaton Posi Differential 30 Spline 1.50in Axle Shaft Diameter 4.56 & Up Ratio Rear 10.5in

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 1985-2005 Chevrolet Astro Base 1985-1995 Chevrolet Astro CL 1985-1995 Chevrolet Astro CS 1996-2005 Chevrolet Astro LS 1987-2005 Chevrolet Astro LT 1996-2012 Chevrolet Express 1500 Base 1996-2012 Chevrolet Express 1500 LS 2001-2002,2006-2012 Chevrolet Express 1500 LT 1996-2012 Chevrolet Express 2500 Base 1996-2012 Chevrolet Express 2500 LS 2006-2012 Chevrolet Express
