Upgrade Your Vehicle To A Safe Transfer Of Increased Power & Torque Across The Axle

Case is up to 50% stronger than OE

Welcome to Auburn Gear’s most advanced limited slip differential, the Grip-N-Loc™. It builds upon exclusive technologies previously found in their limited slip line, but is even more robust to satisfy the extreme demands of serious drivers. If you push the limits of performance and traction, perhaps through competition, or simply through extreme weather driving, Grip-N-Loc® is your best choice. A Grip-N-Loc® will upgrade your vehicle for safe transfer of increased power/torque across the axle. Case material is up to 50% stronger than OE cases. Advanced cone clutch technology provides 25% increase in bias ratio/increased traction. Heat-treated, hardened-steel gear materials for confidence in extreme conditions.
