Generic leveling kits weren't engineered for the ZR2\/AT4X's limited factory UCA dynamic range at additional lift heights. The ReadyLIFT 66-32150 is purpose-built for these platforms with an interlocking puzzle-type pre-load spacer for easy installation and DOM steel UCAs with corrected ball joint angles to restore proper suspension geometry.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe Result\u003c\/strong\u003e\u003cbr\u003e1.5\" of front leveling lift via front strut spacers and interlocking puzzle-type shock assembly pre-load spacers that install without compromising factory strut geometry or clearances. DOM tube steel upper control arms (LH and RH) with corrected ball joint cup angles, heavy-duty replaceable ball joints, and ReadyLIFT TCT (Terrain Control Technology) maintenance-free pivot bushings with side-biter washers restore proper suspension geometry and improve alignment retention at the new ride height — while fully retaining the factory turning radius. Laser cut washers and a full hardware pack complete the kit. The result clears a 33x11.50 on a 20x9 0-offset wheel with no trimming, and up to a 295\/60R20 on 20x9 0-offset with minor trimming.

ReadyLIFT wheel and tire fitment recommendations are based on Wheel Pros wheels and Nitto tires. Actual dimensions vary meaningfully by manufacturer — overall diameter, tread width, aspect ratio, and sidewall construction will differ. Every tire and wheel combination must be test fit prior to final installation. Upgrading to heavier 10-ply (Load Range E) all-terrain or mud-terrain tires will noticeably increase suspension stiffness and alter ride harshness compared to factory 6-ply (Load Range C) tires. Consult your local installer for application-specific guidance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation \u0026amp; Engineering Notes\u003c\/strong\u003e\u003cbr\u003eThis is a bolt-on leveling kit requiring no cutting or welding. UCA hardware must be torqued to specification at ride height. A professional 4-wheel alignment is mandatory post-installation to verify torque specs and lock in corrected geometry. Do not use Auto 4 Hi (4Auto) feature with this kit installed. Lifting your vehicle raises its center of gravity; exercise appropriate caution on- and off-road. All Advanced Driver Assistance Systems (ADAS) including GM Safety Alert Seat, Lane Keep Assist, Forward Collision Alert, and automatic headlight leveling must be checked and recalibrated after installation.\u003c\/p\u003e\u003cblockquote\u003e\n\u003cstrong\u003eEngineering Question:\u003c\/strong\u003e Is your truck a Silverado 1500 ZR2 or GMC Sierra 1500 AT4X, and what is your model year?
