Designed for 2001–2010 Chevrolet and GMC Duramax trucks with a 3.5" axle, these 77" HSP traction bars eliminate violent wheel hop and axle wrap by planting your suspension firmly to the ground. This versatile 77" length is the ideal solution for both 75" and 80" applications, providing a perfect fit for configurations ranging from Crew Cab Short Beds to Long Beds. By tying the axle directly to the frame, you protect critical components like driveshafts and u-joints from the high-torque stress common in LB7, LLY, LBZ, and LMM engines. Whether you are towing, sled pulling, or daily driving, this bolt-on kit ensures maximum power-to-ground efficiency and long-term drivetrain reliability.
