Eaton Posi - GM 10 Bolt 63-79 Corvette

The Eaton Posi - GM 10 Bolt 63-79 Corvette is a locking differential designed for classic Corvette enthusiasts looking to enhance traction during acceleration and cornering. This product is ideal for restorers and performance seekers who want to maintain the authentic performance characteristics of their vehicles from 1963 to 1979.

This limited-slip differential utilizes a clutch-pack design that engages under increased torque demand, effectively locking the axles together to prevent differential action. Engineered to meet original GM 10-bolt specifications, it ensures compatibility with existing 10-bolt housings without requiring modifications. The design allows for progressive lockup, providing some slip during low-speed turns while maximizing traction during hard acceleration.

Corvette owners restoring C1 and C2 models, especially those upgrading their power plants or participating in autocross events, will find this differential essential for converting horsepower into reliable traction. The Eaton Posi is a direct replacement for open differentials in 10-bolt rear ends, making installation straightforward and efficient.
