HSP 58" Bolt-On Traction Bars 3.5in Axle Diameter for 2001-2010 Chevrolet / GMC Duramax LB7 / LLY / LBZ / LMM The 035-1-HSP, or HSP 58" Bolt-On Traction Bars for 3.5" axle diameters, are designed for the 2001-2010 Chevrolet and GMC Duramax trucks. These traction bars arent just for modified builds—stock trucks, drag applications, and daily drivers will all benefit. Why You Need the HSP 58" Traction Bar Kit Diesel trucks carry significant weight up front, especially with aftermarket accessories like plows or winches. Combined with limited rear traction and massive torque output, this often causes wheel hop—a violent up-down motion of the rear wheels under load. While it might seem like a minor issue, wheel hop can destroy driveshafts, axles, u-joints, and yokes. Installing traction bars significantly reduces this risk while improving traction and power transfer. What Makes HSP Traction Bars Different Our 58" traction bars anchor your rear axle to the frame, minimizing flex and movement. This ensures more power gets to the ground efficiently. Each kit includes premium hardware and bushings—no cheap parts or sloppy fitment here. Our bars are trusted by street trucks, race setups, and tow rigs across the country. Theyre simple to install, reliable, and powder coated to suit any build.
