You need solid billet aluminum construction, not spot-welded stamped steel. The ReadyLIFT 66-3085 is the best quality, best design leveling kit for the new body style GM 1500 platform, delivering 2.25\" of front lift with zero compromise to factory ride quality.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe Result\u003c\/strong\u003e\u003cbr\u003eTwo CNC-machined 6061-T6 solid billet aluminum top mount strut extensions and two 6061-T6 billet aluminum lower strut mount spacers, with all necessary new strut hardware, deliver 2.25\" of front lift without compressing the factory springs or requiring any permanent modification. Factory OEM ride quality and comfort are fully preserved. The result is a level stance that clears a 33x11.50 on a 9\" wide +12 offset wheel with no rubbing, or up to a 295\/65R18, 285\/60R20, or 285\/50R22 depending on wheel size. Note: 1\/2\" front wheel spacers (ReadyLIFT 15-3485) may be required to run 285 or larger tires on factory wheels due to backspacing variation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eVerified Fitment (OFAS Standard)\u003c\/strong\u003e\u003cbr\u003e✅ Fits: 2007–2020 Chevrolet Silverado 1500 6-lug (new body style)\u003cbr\u003e✅ Fits: 2007–2020 GMC Sierra 1500 6-lug (new body style)\u003cbr\u003e✅ Fits: 2015–2018 Silverado\/Sierra 1500\u003cbr\u003e❌ Does NOT fit: Vehicles equipped with factory Air-Ride suspension\u003cbr\u003e❌ Note: Vehicles equipped with Magnetic Ride Control will require MRC system re-calibration after installation\u003cbr\u003e❌ Note: 2017 models with stamped steel upper control arms require either aftermarket UCAs or factory aluminum UCAs before installing this kit — stamped steel UCAs on 2017 models are known to have ball joint issues when leveled or lifted\u003cbr\u003e❌ Note: Trucks with a wheel hub-to-fender measurement greater than 22\" already have factory or aftermarket front lift — install WITHOUT the lower horseshoe spacer to avoid component interference and excessive wear\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLift Height\u003c\/td\u003e\n\u003ctd\u003e2.25\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Tire Diameter\u003c\/td\u003e\n\u003ctd\u003e33\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eCNC-machined 6061-T6 solid billet aluminum (top mount strut extensions x2, lower strut mount spacers x2)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHardware\u003c\/td\u003e\n\u003ctd\u003eNew strut hardware included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFactory Spring Compression\u003c\/td\u003e\n\u003ctd\u003eNone — factory springs not compressed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePermanent Modifications\u003c\/td\u003e\n\u003ctd\u003eNone required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e66-3085\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eReadyLIFT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eWheel \u0026amp; Tire Fitment\u003c\/strong\u003e\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eWheel Size\u003c\/th\u003e\n\u003cth\u003eMax Tire\u003c\/th\u003e\n\u003cth\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e9\" wide, +12 offset\u003c\/td\u003e\n\u003ctd\u003e33x11.50\u003c\/td\u003e\n\u003ctd\u003eNo rub\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e18\"\u003c\/td\u003e\n\u003ctd\u003e295\/65R18\u003c\/td\u003e\n\u003ctd\u003eNo rub\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e20\"\u003c\/td\u003e\n\u003ctd\u003e285\/60R20\u003c\/td\u003e\n\u003ctd\u003eNo rub\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e22\"\u003c\/td\u003e\n\u003ctd\u003e285\/50R22\u003c\/td\u003e\n\u003ctd\u003eNo rub\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003e1\/2\" front wheel spacers (ReadyLIFT 15-3485) may be required to run 285 or larger tires on factory wheels due to backspacing variation between factory wheel options. 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 of strut studs and no permanent modification to factory parts. Before installing, measure from the center of the wheel hub to the bottom edge of the fender at the 12 o'clock position (wheels pointing straight forward, using a plumb bob for a clean vertical). If this measurement exceeds 22\", your truck already has factory or aftermarket front lift — install WITHOUT the lower horseshoe spacer to prevent component interference and excessive wear. 2017 models with stamped steel UCAs must upgrade to aftermarket or factory aluminum UCAs before installation. Vehicles with Magnetic Ride Control require MRC re-calibration post-install. A professional 4-wheel alignment is mandatory post-installation. All Advanced Driver Assistance Systems (ADAS) including GM Safety Alert Seat, Lane Keep Assist, and Forward Collision Alert must be checked and recalibrated after installation.\u003c\/p\u003e\u003cblockquote\u003e\n\u003cstrong\u003eEngineering Question:\u003c\/strong\u003e What is your exact model year, and does your truck have factory Air-Ride, Magnetic Ride Control, or stamped steel upper control arms? If your 2017 Silverado or Sierra has stamped steel UCAs, UCA upgrade is required before installing this kit. Measure your wheel hub-to-fender distance before ordering to confirm lower spacer configuration.\u003c\/blockquote\u003e","brand":"ReadyLIFT Suspension","offers":[{"title":"Default Title","offer_id":51631846097217,"sku":"66-3085","price":249.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/66-3085.jpg?v=1776291286","url":"https:\/\/obsidianforgedautosupply.com\/products\/readylift-2-25-billet-leveling-kit-silverado-sierra-1500-2007-66-3085","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
