It’s not just about durability, this kit also gives you dialed-in alignment control with Kryptonite’s exclusive Hex Caster Eccentric, letting you make quick and precise adjustments that actually stay put. Whether you’re blasting down trails, hauling heavy loads, or daily driving on a lift, this arm kit is ready for it all. The design even clears up to a 37x13.5 tire on a stock 20-inch rim with 5.5 inches of backspacing, no problem. Plus, it comes with everything needed for installation, so you're not left hunting for extra parts. And with Kryptonite’s legendary lifetime warranty backing it all, you can hit the road, or the dirt, knowing your front end is locked in tight.

Built To Handle Bigger Tires And More Travel

The Death Grip Radius Arm Kit from Kryptonite is a precision-engineered solution for lifted Super Duty trucks that demand more than stock arms can offer. Each arm is fully boxed and hand welded from high-strength steel, ensuring maximum rigidity under heavy loads and rough terrain. A built-in tire clearance pocket allows for the use of 37x13.5 tires with a 5.5-inch backspaced 20-inch wheel, giving you more flex and space at full steering lock. The core of the system lies in its alignment capability, Kryptonite’s patented Hex Caster Eccentric allows for 2-degree caster corrections across five preset positions, making alignment easy to dial in whether your truck sits at stock height or up to 6 inches of lift. Unlike slotted cam systems that can slip over time, this hex design locks into place for reliable long-term alignment. Each kit includes all necessary hardware for install and is sold as a direct bolt-on pair. Built for serious off-roaders and hard-use work trucks, this arm kit offers the alignment control, durability, and tire clearance needed to get the most from your suspension upgrades.
