ReadyLift® leveling kits are the fastest, safest, least expensive way to bring the front of your vehicle level with the rear. Our innovative Smart Strut Technology mounts on top of the strut assembly, eliminating the hassle, time and danger of compressing springs. ReadyLift® steel strut extension will maintain a smooth OEM ride without adding pressure to stock suspension components, guaranteed. The strut extension provides 3 Inch of lift which gives clearance to add up to 33 Inch wheels and tires to the Toyota Tundra 2WD and 4WD. Installation is simple and requires no strut preloading, cutting, or modification of factory installed parts.
