Description
Eaton Model : 19556-010

Application: 1964-1981 GM Truck w/ 12 bolt rear cover

Axle Shafts: 30 Spline

Gear Ratios: 4 Series (3.73 +)

The Eaton Posi limited-slip differential prevents wheel slip before it can get started. A central spring assembly pre-loads a carbon disc clutch pack that is located behind each side gear. As torque input increases, the clamping load on the clutch packs also  increases. This causes the clutch packs to grab and transfer power to the other wheel.

Muscle cars, hot rods and mild off-road vehicles will benefit from Eaton's limited-slip differential when traction is a concern.
