Because the factory upper control arms run out of range when these trucks are lifted further, the kit includes tubular upper control arms along with billet strut spacers to level the truck without conflicting with factory strut geometry.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePart number:\u003c\/strong\u003e ReadyLIFT 66-3921\u003c\/p\u003e\n\u003ch2\u003eKey features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e1.75\" of front lift for factory-lifted AT4 and Trail Boss trucks\u003c\/li\u003e\n  \u003cli\u003eDOM tube steel upper control arms with corrected ball joint cup angles and heavy-duty replaceable 1-ton ball joints\u003c\/li\u003e\n  \u003cli\u003eTerrain Control Technology (TCT) maintenance-free pivot bushings with side-biter washers to help hold alignment\u003c\/li\u003e\n  \u003cli\u003eCNC-machined billet aluminum top and bottom strut spacers\u003c\/li\u003e\n  \u003cli\u003eAvoids ball joint binding and strut\/CV axle contact issues of traditional leveling kits on these trucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhat's included\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo tubular steel upper control arms with TCT pivot bushings and 1-ton ball joints\u003c\/li\u003e\n  \u003cli\u003eCNC-machined billet aluminum top and bottom strut spacers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e2019-2026 GMC Sierra 1500 AT4\u003c\/li\u003e\n  \u003cli\u003e2019-2026 Chevy Silverado 1500 Trail Boss\u003c\/li\u003e\n  \u003cli\u003eNot compatible with Sierra AT4X or Silverado ZR2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTire fitment\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eAT4 and Trail Boss do not fit the same tire size because of different front fender openings\u003c\/li\u003e\n  \u003cli\u003eAT4: 275\/60-20 maximum on a 20x9 wheel with 0 offset\u003c\/li\u003e\n  \u003cli\u003eTrail Boss: 295\/65-20 maximum on a 20x9 wheel with 0 offset\u003c\/li\u003e\n  \u003cli\u003eTrail Boss on factory wheels: up to 285\/75R18 with wheel spacers\u003c\/li\u003e\n  \u003cli\u003eReadyLIFT bases its wheel and tire recommendations on specific wheel and tire brands, and sizes vary by manufacturer, so test-fit every wheel and tire combination before installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eInstall notes\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eEstimated installation time: 3.5 hours +\/- 0.5 hours (excludes alignment and wheel\/tire assembly).\u003c\/li\u003e\n  \u003cli\u003eRead the instructions completely before starting.
