Description

(This Package is designed to level the front of GM trucks a maximum of 2 inches! Any adjustment beyond 2 inches over stock height will most likely result in complete front shock failure!) Kryptonite leveling kits are the fastest, safest, least expensive way to bring the front of your GM Truck 2 inches closer to the rear. Our torsion keys are designed to grab the “FLAT” of the torsion bar for a tighter, sturdier fit. Kryptonite torsion keys are forged, making them 25% stronger than factory and primed to last the life of your vehicle. The adjustable torsion key provides 1” to 2” of lift and gives clearance to add up to 34" wheels and tires to your GM Truck. Designed to keep the factory ride and will not add more pressure on the stock suspension components. Through our innovative engineering, these kits cost thousands less than a traditional lift kit. Kit Includes everything needed for installation; 1 x Kryptonite Upper Control Arm Pair 4 x Control arm sleeves 8 x Control arm Bushings 2 x Upper Bump Stops 2 x Kryptonite Bolt on Upper Ball Joints 1 x Hardware package 2 x Leveling Keys 1 x Shock Extension Kit The leveling torsion key provides up to 2”of lift and gives clearance to add up to 34" tire. Shock extensions allow you to use your stock shocks. (Kryptonite No Fine Print Lifetime warranty)-Kryptonite steering and suspension components are warrantied for life to their original purchaser. This warranty is against any manufacturer defects, premature wear or breakage. Race it, jump it, off road it, wreck it, lift it, I think you get it? We don't care. If you can break it we will replace it.

  • Service sells!!
I never right reviews on here! RD parts shipped this around a holiday, got it to me quickly, and got back to my message right away. Stuff like this is what brings customers back. This kit is obviously awesome, but if I need parts in the future I will be looking to RD parts! Plus, I can’t believe how much better the ride is up front. ... show more
