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 Infiniti QX56, 2004-2007 Nissan Armada, and 2004-2007 Nissan Titan. For information about tire and wheel sizes please visit the ReadyLift Tire Sizing and Calculator Page.
Installation is simple and requires no strut preloading, cutting, or modification of factory installed parts. While other kits cost thousands to buy and hours to install, ReadyLIFT® can be installed one to two hours and costs less than the price of a single custom wheel.
ReadyLift® Lifetime Warranty Included! All ReadyLift® products are backed by a lifetime warranty for as long as you own your vehicle and includes all necessary parts, hardware, detailed installation instructions, and two color decals.
