The Eaton Posi is the perfect way to control traction in street rods, light duty pickups and everyday drivers.
The Eaton Posi prevents wheel slip before it can get started. To do that, carbon disc clutch packs, preloaded by a central spring assembly, are located behind each differential side gear. When torque input increases the clamping load on the clutch packs increases. That causes the chatter-free clutch packs to grab and transfer power to the other wheel. The Eaton Posi is fully rebuildable with one of our specially formulated clutch kits.
Muscle cars, hot rods and mild offroad vehicles should look to Eaton’s limited-slip differential for their traction answers. And the fact is, Eaton’s Posi units are virtually bulletproof.
Features:
• Carbon Friction Technology
• Precision-Forged Gears
• Automatic
•Rebuildable
