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.
Operation
The Posi prevents wheel slip before it can get started. Racebred 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.
Performance
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.
Lubrication
A quality GL5 petroleum (mineral) based or synthetic oil with sufficient friction modifier must be used.
Features
- Superior rebuildable design
- Race-bred carbon friction discs
- Limited-slip operation
- Smooth and automatic engagement - no driver action needed
- Tunable via various spring packs (a.k.a. pre-loads)
