The Kryptonite Stage 3 leveling kits are the easiest, safest, least expensive way to bring the front of your truck 2" closer to the rear. The forged torsion keys are fully adjustable, designed to grab the “FLAT” of the torsion bar for a tighter, sturdier fit, effectively increasing strength by 25% over OEM. Engineered to keep the factory ride quality, increase articulation, maintain geometry, and never add pressure on other suspension components.
There's an old saying in the automotive world: "Buy once, cry once." You'll never have to worry about replacing control arms again; even if you plan on running your truck into the ground, Kryptonite UCAs will never fail you. They are the heaviest-duty suspension components on the market. They are stiffer at low-speed articulation, however, you get unparalleled control and travel over any terrain, which is extremely beneficial for those who have larger wheels and tires.
