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 (SST) mounts on top of the strut assembly eliminating the hassle time and danger of compressing springs. ReadyLIFT strut extensions will maintain a smooth OEM ride without adding pressure to stock suspension components guaranteed! The 66-4010 strut extensions for the 2004-2015 Nissan Titan trucks provide 1.5" of leveling lift which gives clearance to add up to 33" tires to the Nissan Titan. NOTE: Not for use on Pro 4X models.
