Note: This kit is designed specifically for solid-rear-axle leaf-spring configurations.

Tame the massive torque of your L5P Duramax with the S&B Traction Bar Kit, specifically engineered to eliminate axle wrap and wheel hop on late-model GM heavy-duty trucks. These bars use a patented, adjustable-length design and specialized bushings to deliver rock-solid rear-end stability without limiting your suspension’s natural travel or articulation. Whether you're towing heavy or hitting the track, these bars ensure your power is delivered directly to the pavement for maximum performance and durability.
