This imbalance paired with rear-wheel torque leads to \u003cstrong\u003ewheel hop \u003c\/strong\u003ea violent up-and-down bounce of the rear wheels when traction is lost. Wheel hop can cause catastrophic damage to driveshafts, axles, yokes, and u-joints. HSPs 58\" traction bars are a preventative measure that ensures power reaches the pavement smoothly and safely.\u003c\/p\u003e\n\u003ch3\u003eWhat Makes the HSP Kit Different?\u003c\/h3\u003e\n\u003cp\u003eThe HSP 58\" Bolt-On Traction Bars connect the rear axle to the truck frame using precision-engineered brackets and bushings. This eliminates unwanted axle wrap, stabilizes suspension under load, and ensures optimal traction and power delivery. These bars are built with top-tier materials and are tested across drag strips, work sites, and everyday driving. They install easily and fit perfectly the first time, with no clunky parts or guesswork.\u003c\/p\u003e\n\u003ch3\u003eWhats Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x 58\" Bolt On Traction Bar (HSP-IN-678-1)\u003c\/li\u003e\n\u003cli\u003e1x 58\" Bolt On Traction Bar (HSP-IN-678-1)\u003c\/li\u003e\n\u003cli\u003e1x Front Traction Bar Bracket Left (HSP-IN-657-D)\u003c\/li\u003e\n\u003cli\u003e1x Front Traction Bar Bracket Right (HSP-IN-657-P)\u003c\/li\u003e\n\u003cli\u003e1x Rear Traction Bar Bracket (11-19) (HSP-IN-663-2)\u003c\/li\u003e\n\u003cli\u003e1x Rear Traction Bar Bracket (11-19) (HSP-IN-663-2)\u003c\/li\u003e\n\u003cli\u003e4x 1\/8\" Aluminum Rivet (RFB-098-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x Small HSP Logo (Flat) (RFB-752-F-RFAB)\u003c\/li\u003e\n\u003cli\u003e4x Polyurethane Bushings (RFB-835-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x Bushing Inserts (DOM Tubing) (RFB-836-RFAB)\u003c\/li\u003e\n\u003cli\u003e8x 1\/2\" x 1.062\" OD Low Carbon Flat Washer (RFB-774-RFAB)\u003c\/li\u003e\n\u003cli\u003e8x 1\/2\"-13 x 1-1\/2\" Grade 8 Hex Flange Bolt - Machined (RFB-775-1-RFAB)\u003c\/li\u003e\n\u003cli\u003e8x 1\/2\"-13 Eco Finish Steel Top Lock Nut (RFB-776-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x 1\/2\" Pull Wire (RFB-777-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x 5\/8\"-11x3-1\/4\" Grade 8 Bolt (RFB-848-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x 5\/8\"-11x3-3\/4\" Grade 8 Bolt (RFB-849-RFAB)\u003c\/li\u003e\n\u003cli\u003e4x 5\/8\"-11 Nylon Lock Nut (RFB-850-RFAB)\u003c\/li\u003e\n\u003cli\u003e8x 5\/8\" Washer (RFB-851-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x Flex Joint (3\/4\"-16 Thread, Bolt Dia. .625\") (RFB-721-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x Jam Nut (3\/4\"-16) (RFB-722-RFAB)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLML: VIN Code 8\u003c\/li\u003e\n\u003cli\u003eL5P: VIN Code Y\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eHow to Confirm Fitment:\u003c\/strong\u003e The 8th character of your VIN indicates the engine code; the 10th character indicates the model year.\u003c\/p\u003e\n\u003ch3\u003eSpecial Note\u003c\/h3\u003e\n\u003cp\u003eThe 58-inch traction bars are designed to fit Regular Cab trucks with 8-foot beds.
