GRIP LS - Gm 10 Bolt 8.5 in 30 Spline

The GRIP LS – GM 10 Bolt 8.5 in 30 Spline is a limited-slip differential upgrade designed for serious enthusiasts and mechanics looking to improve traction and handling in GM light-duty trucks and performance vehicles. If you're running factory open differentials that spin one wheel under acceleration, this unit transforms off-road capability, launch feel, and mid-corner stability without requiring full locker aggression. Whether you're building a track-focused Camaro, upgrading a work truck, or enhancing a weekend warrior, the GRIP LS strikes the balance between daily drivability and hard-use performance that OEM equipment simply cannot match.

POWERTRAX's GRIP series uses a clutch-style limited-slip design that progressively locks as torque increases, eliminating wheel slip during acceleration while still allowing the inside wheel to rotate slightly during cornering. The 30-spline design meshes perfectly with GM 10-bolt carrier assemblies found in most third-gen Camaros, Firebirds, and S-series trucks, providing bolt-in compatibility with minimal modification. Internal friction plates and springs work together to bias power to the wheel with traction, dramatically reducing torque steer and improving launch characteristics. The compact 8.5-inch diameter footprint fits within OEM housing dimensions, and the 20.53-pound assembly integrates seamlessly into existing axle packages without requiring custom fabrication.

Installation suits DIY mechanics and professional shops alike, requiring only basic differential service knowledge and standard hand tools. The GRIP LS performs best in street and moderate off-road use where smooth, progressive locking outperforms full spools on pavement; it reduces tire wear compared to lockers while delivering noticeable improvement over open differentials. Verify your 10-bolt carrier's spline count and 8.5-inch diameter before ordering to ensure fitment. Proper fluid selection and break-in procedures maximize clutch plate longevity and performance, making this upgrade an intelligent choice for builders prioritizing reliability alongside traction gains.
