Will Not Fit vehicles equipped with Air Bag Rear Suspension Systems.Developed and rigorously tested by in-house engineers, our MAX-Torsion Keys and High-Density Delrin Coil Spring Spacers are precision CNC machined from optimal, corrosion-resistant material blends, ensuring a lifetime of dependability under even the most extreme riding conditions. If you’re looking to level the stance of your Hummer, fit larger wheels and tires or pick up some ground clearance out on the trails, we have a kit tailored specifically to your truck and your needs.We are proud to offer you our Caster/Camber Adjusting Kit, a simple but very effective solution for regaining proper wheel alignment after altering the geometry and suspension angles. Incorrect camber adjustment, as well as sudden and extreme changes in alignment cam position, can negatively affect the performance of your vehicle and cause damage to ball joints, control arms, spindles, axles, hubs, wheels, and tires. Precision CNC Laser Cut from 3/16" Steel and designed with seven alignment holes to keep the alignment locked in place, our adjusting kit allows for +/-1.5 degrees of Camber and Caster adjustment, in 0.5 degrees increments, helping you to regain proper alignment on your lifted pickup truck, prevent damage to steering and suspension parts, and improve your vehicle safety.Note: *An alignment is always recommended after altering the height of your vehicle.*Our re-indexed torsion keys are adjustable anywhere from 1" to 3" of lift and offer TWICE the strength of the factory keys.
