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” of adjustable lift which gives clearance to add up to 33" wheels and tires to the Dodge Durango. For information about tire and wheel sizes please visit the ReadyLift Tire Sizing and Calculator Page. ReadyLift® keys are guaranteed never to affect the OEM ride and will not add more pressure on the stock suspension components. Through our innovative engineering, ReadyLIFT® kits cost thousands less than a traditional lift kit and install in about 1-2 hours. Fits 2004-2010 Durango 2wd & 4wd.
