Auburn Gear - 546034 - Compatible with/Replacement for GM 12BLT 3 SER TRUCK 2.76-3.42 30T

Grip-n-loc ™ utilizes exclusive cone-clutch technology to impart a bias across the axle when one wheel experiences low traction. when a wheel begins to lose traction and spins, the differential shifts torque away from the low traction wheel to the wheel with the most traction. as wheel slippage increases so do the gripping force within the differential so the cone clutches distribute power across the entire axle. the wheel experiencing the most traction receives more power and the wheel with less traction gets less power, helping the driver maintain forward motion. by multiplying torque to one wheel, greater forces come into play within the differential. to retain integrity under high-stress grip-n-loc ™ is engineered with higher-grade materials than used in oe type differentials.
