1963-1979 Corvette (IRS)

Suits 2.73-3.90 Ratio
3 Series Carrier

Superior re-buildable design
Race-bred carbon friction discs
Limited-slip operation
Smooth and automatic engagement - no driver action needed
Tuneable via various spring packs (a.k.a. pre-loads)

The Eaton Posi limited-slip differential is the perfect way to control traction in muscle cars, street rods, light duty pickups and all types of tarmac running race cars.

The Eaton Posi is smooth and automatic, requiring no driver input. Featuring pyrolytic carbon clutches and a rebuildable design, the Posi can be custom tuned for your desired performance. The Posi prevents wheel slip before it can get started. Race-bred carbon disc clutch packs, preloaded by a central spring assembly, are located behind each differential side gear. When torque input changes (one wheel slips), the clamping load on the clutch packs increases, causing them to smoothly transfer power to the other wheel as needed.
