ReadyLIFT leveling kits are the fastest, safest, least expensive way to bring the front of a Silverado or Sierra level with the rear. ReadyLIFT's torsion keys are designed to grab the FLAT of the torsion bar for a tighter, sturdier fit. CNC-machined adjuster bolt pockets and 10.9 grade metric hardware allow for proper bolt seating, ensuring an accurate and safe adjustment. Only ReadyLIFT torsion keys are forged, making them 25% stronger than OEM and primed to last the life of your vehicle. The adjustable 66-3050 torsion key provides 2”-2.5" of lift and gives clearance to add up to 33" wheels and tires to the Silverado.
