  • Tunable via various spring packs (a.k.a. pre-loads)
  • Rebuildable design

  • Smooth, automatic engagement

Prevent wheel slip before it starts

The Eaton Posi limited-slip differential 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.
