Product Details

HSP Diesel has come out with the first true bolt-on traction bars for the LML! Trucks in most cases carry more weight on the front half of the truck than the rear because of the large engines, and turbo systems that provide the necessary horsepower, and torque, that we love in today's trucks. Wheel hop issues come directly from the factory. Even at factory power levels wheel hopping can cause major repairs to your driveshafts, axle's, yokes, u-joint, and suspension components. While no one wants to deal with these issues, HSP Diesel has a solution to the dreaded wheel hop. There are many knock off built traction bar kits available, and many do not include quality components, that over time become very loud and clunky. These cheap kits can also do damage from poor design and inadequate components. If your tires are not touching the ground, you're not getting traction! HSP Diesel has worked with our customers, and our own trucks to create a simple, well-engineered, affordable solution to wheel hop, and increased traction. Quality, strength, and longevity are the three things you can expect from your new HSP traction bars. Proven from drag racers, sled pullers, and street monsters this kit is an all-around affordable kit for everyone. We pay attention to what our valuable customers say, and this kit is the easiest, best-fitting, and best-looking setup you will find. Fits 2011-2016 Regular Cab 8ft. Box Trucks.
