2011-2019 Duramax LML/L5P HSP Diesel 70" Bolt-On Traction Bars 4" Axle Diameter (535-2-HSP)

The HSP 70" Bolt-On Traction Bars are designed for 2011-2019 Chevrolet and GMC Duramax trucks with 4" axle diameters. These are the first true bolt-on traction bar kits made specifically for LML and L5P trucks and are ideal for stock trucks, drag builds, and street monsters alike.

Why You Need This Kit
Diesel trucks are notoriously front-heavy due to large engine bays, plow mounts, and other accessories. This imbalance, paired with rear-wheel drive and high torque output, often leads to wheel hop. Wheel hop can cause serious damage to driveline components including driveshafts, u-joints, axles, and yokes. Installing traction bars mitigates this problem and allows your truck to reliably transfer power to the ground.

What Makes the HSP Kit Different?
The HSP 70" Traction Bars effectively stabilize the rear axle by tying key points on the axle directly to the frame, reducing axle wrap and enhancing traction. These bars include high-quality joints and bushings, engineered for both strength and longevity. This kit offers precise fitment, proven durability under extreme use, and powder coating options for custom styling. Installation is straightforward with no special tools required.
