2001-2010 Duramax HSP Diesel 70" Bolt-On Traction Bars 3.5" Axle Diameter (035-2-HSP)
The 035-2-HSP, or HSP 70" Bolt-On Traction Bars for 3.5" axle diameters, are built for the 2001-2010 Chevrolet and GMC Duramax trucks. These bars arent just for modified rigs”this kit performs exceptionally well on stock trucks, daily drivers, drag builds, and everything in between.
Why You Need the HSP 70" Traction Bar Kit
Diesel trucks tend to be front-heavy due to their large engines, plow equipment, and other accessories. With less weight over the rear tires and the high torque output of Duramax engines, this often results in wheel hop”a violent up-down motion of the wheels while trying to gain traction. Though it may seem harmless, wheel hop can damage driveshafts, axles, u-joints, and more. If you're spinning, you're not winning”and traction bars are the solution.
What Makes HSP Traction Bars Different
The HSP 70" bars anchor the axle to the frame, eliminating unwanted movement under load. This ensures smoother power delivery to the ground. Our traction bar kits are engineered to last”no clunky fitment or inferior parts here. Whether you're launching hard at the track or pulling a trailer, HSP traction bars have been proven over millions of miles. They're easy to install and built for long-term performance.
