ReadyLIFT leveling kits are the fastest, safest, least expensive way to bring the front of your vehicle level with the rear. Our 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 66-1080 torsion key provides 1.5 to 2.25 inches of adjustable lift which gives clearance to use up to 33 inch tires on the Dodge Durango.
