The kit is engineered around a triple-rate coil design that separates droop, ride, and overload spring rates to improve both daily comfort and off-road capability.\u003c\/p\u003e\n\u003cp class=\"product-shipping-note\"\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time.

For Tundra owners, this means the rear suspension stays compliant on paved roads and light trails, then resists bottoming out under heavy cargo, towing tongue weight, or hard off-road impacts. No separate helper spring or air bag is required to achieve that range of response.\u003c\/p\u003e\n\n\u003ch2\u003eDual-Stage Powder Coating\u003c\/h2\u003e\n\u003cp\u003eEach spring receives a two-stage powder coat finish for corrosion resistance, relevant for Tundras driven in wet climates, salted roads, or muddy off-road conditions where bare steel coils degrade quickly. The finish is applied before the springs leave the factory, so there is no field prep required at installation.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVehicle-specific lift:\u003c\/strong\u003e 0.75\" rear lift on TRD Off-Road, TRD Sport, TRD Rally, and TRD Pro models; 1.25\" rear lift on non-TRD Tundra\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTriple-rate coil design:\u003c\/strong\u003e Separate ICON-engineered droop, ride, and overload rates in a single spring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-stage powder coat:\u003c\/strong\u003e Two-layer finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLifetime guarantee:\u003c\/strong\u003e Against sagging and breakage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eImproved on- and off-road performance:\u003c\/strong\u003e Over stock coil springs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBrand\u003c\/td\u003e\n      \u003ctd\u003eICON Vehicle Dynamics\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003e51211\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2022–2026 Toyota Tundra\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePosition\u003c\/td\u003e\n      \u003ctd\u003eRear\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift Height (TRD Off-Road \/ Sport \/ Rally \/ Pro)\u003c\/td\u003e\n      \u003ctd\u003e0.75 in over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift Height (Non-TRD)\u003c\/td\u003e\n      \u003ctd\u003e1.25 in over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpring Design\u003c\/td\u003e\n      \u003ctd\u003eTriple-rate (droop, ride, overload)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFinish\u003c\/td\u003e\n      \u003ctd\u003eDual-stage powder coat\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e55 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThis kit suits 2022–2026 Toyota Tundra owners seeking a modest rear lift with improved ride quality on and off road, particularly those running or planning to run ICON shocks and suspension components. It is compatible with OEM wheels and tires, and ICON notes fitment with 17x8.5-inch wheels at 5.75-inch backspace or 18x9-inch wheels at 6-inch backspace; 35x12.50-inch tires may fit with minor fender trimming.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThese springs are not compatible with Tundra models equipped with the factory Load-Leveling Rear Height Control Air Suspension system. Advertised lift heights are based on a stock-weight vehicle and will vary with added accessories or cargo. ADAS recalibration is required after installation. Tundra owners wanting less rear lift should consider ICON part number 51210 instead.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eHow much rear lift do these springs provide on a TRD Tundra versus a standard Tundra?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe ICON Triple Rate Rear Coil Spring Kit (SKU 51211) delivers 0.75 inches of rear lift on 2022–2026 Tundra models equipped with TRD Off-Road, TRD Sport, TRD Rally, or TRD Pro suspension packages.
