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, petroleum-mineral based, GL5 rated 80w-90 gear oil should be used. It is necessary to add a four-ounce bottle of friction modifier for optimum performance (if friction modifier has not already been added to the petroleum-mineral based gear oil).

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)
