Limits wheel-slip for improved traction, handling, and stability. Seamless installation, no wiring/pneumatic connections, retrofittable with existing S110, S111, S130, and S140 axles. Longer lifespan due to superior lifetime torque bias performance (~3:1 in slip event). No special lubricants or friction modifiers required.
