Eaton Posi - GM 10-Bolt 64-82 8.2in 19603-010

If you're running a classic Chevy with a 10-bolt and need predictable, straight-line traction without the chatter and slip of an open diff, the Eaton Posi is your answer. This limited-slip carrier locks both wheels under load, giving you the grip you need at the strip or on the street while maintaining drivability on corner exit. It's the go-to upgrade for anyone serious about eliminating wheel spin.

The Eaton Posi uses a clutch-pack design that automatically biases torque to the wheel with traction, keeping power delivery smooth and controllable across a wide range of driving conditions. Built on proven engineering, it's a direct bolt-in replacement that requires no exotic fabrication—just install and go.
