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 66-4000 strut extension provides 2" of lift which gives clearance to add up to 33" wheels and tires to the 2004-2007 Nissan Titan, Nissan Armada, and Infiniti QX56.  For information about tire and wheel sizes please visit the ReadyLIFT.
