ReadyLIFT is the leader in suspension leveling systems, and the 66-5251 SST kit is the proven solution for the first and second generation Tundra platform — fabricated steel top mount strut extensions with all the geometry correction hardware included, no spring compression required.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe Result\u003c\/strong\u003e\u003cbr\u003eThree inches of front lift via one pair of fabricated steel top mount strut extensions, paired with differential drop spacers to maintain proper CV joint operating angles, sway bar mount spacers to correct sway bar geometry, and skid plate spacers to maintain factory skid plate clearance. The result is a level, aggressive stance that clears a 33x12.50 on a 9\" wide +25 offset wheel with no rubbing, or up to a 35\" tire on a positive offset wheel with minor trimming. Factory ride quality is fully preserved.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eVerified Fitment (OFAS Standard)\u003c\/strong\u003e\u003cbr\u003e✅ Fits: 2007–2021 Toyota Tundra (2WD and 4WD — all trims including TRD, SR5, Rock Warrior)\u003cbr\u003e❌ Does NOT fit: Toyota Tundra TRD Pro\u003cbr\u003e❌ Does NOT fit: 2022 and newer Tundra (new generation — see 66-52201 for 2022–2025 applications)\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\u003e3.0\" Front\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Tire Diameter\u003c\/td\u003e\n\u003ctd\u003e33\" (35\" on positive offset wheel with trimming)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFront Components\u003c\/td\u003e\n\u003ctd\u003eFabricated steel top mount strut extensions (x1 pair), differential drop spacers, sway bar mount spacers, skid plate spacers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDesign\u003c\/td\u003e\n\u003ctd\u003eBolt-on, no spring compression required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e66-5251\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\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, +25 offset\u003c\/td\u003e\n\u003ctd\u003e33x12.50\u003c\/td\u003e\n\u003ctd\u003eNo rub\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e17\"\u003c\/td\u003e\n\u003ctd\u003e33x12.5R17\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\u003e305\/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\u003e305\/55R20 or 33x12.5R20\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\u003e33x12.5R22\u003c\/td\u003e\n\u003ctd\u003eNo rub\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePositive offset wheel\u003c\/td\u003e\n\u003ctd\u003e35\"\u003c\/td\u003e\n\u003ctd\u003eMinor trimming required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003eReadyLIFT 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 spring compression, no cutting, and no welding. Differential drop spacers, sway bar mount spacers, and skid plate spacers must all be installed to maintain proper geometry and factory component clearances. A professional 4-wheel alignment is mandatory post-installation. Lifting your vehicle raises its center of gravity; exercise appropriate caution on- and off-road. All Advanced Driver Assistance Systems (ADAS) including Toyota Safety Sense (TSS), Pre-Collision System, Lane Departure 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 Tundra a TRD Pro, and what is your model year — 2007–2021 or 2022 and newer? TRD Pro models are not compatible with this kit, and the 2022+ Tundra is a new generation requiring a different leveling solution (see 66-52201).\u003c\/blockquote\u003e","brand":"ReadyLIFT Suspension","offers":[{"title":"Default Title","offer_id":51631849537857,"sku":"66-5251","price":269.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/66-5251.jpg?v=1776292993","url":"https:\/\/obsidianforgedautosupply.com\/products\/readylift-3-0-sst-leveling-kit-toyota-tundra-2007-66-5251","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
