In a push to provide unparalleled ride quality and vehicle dynamics for everything from high-speed desert running to off the grid expedition, the RXT Rear Suspension System was born. The RXT Rear Suspension System is a combination of an all new ICON multi-rate leaf spring, a hydraulic rear bump stop kit, and three RXT-specific 2.5 Aluminum Series rear shock options. Installation of this system replaces the aforementioned “limiting factors” and completely redefines the potential of the 2007-2021 Toyota Tundra with a 20% increase in wheel travel and the ability to adjust the leaf spring rate to compensate for varying vehicle setups.\n2007-2021 TUNDRA RXT STAGE 2 SYSTEM\nRecommended Aftermarket Tires: 35\" x 12.50\" (Larger tires may fit but fender trimming and modifications will be required.)\n\u003cul\u003e\n  \u003cli\u003eICON RXT Multi-Rate Leaf Spring: Potential for increased wheel travel when used with RXT shock without sacrificing up-travel (up to 20% over stock)\u003c\/li\u003e\n  \u003cli\u003eICON Hydraulic Rear Bump Stop Kit: “ICON 1K” tested under rigorous off-road conditions to validate tune, performance, strength, and durability\u003c\/li\u003e\n  \u003cli\u003eICON RXT Multi-Rate Leaf Spring: “ICON 1K” tested under rigorous off-road conditions to validate tune, performance, strength, and durability\u003c\/li\u003e\n  \u003cli\u003eICON RXT Rear Shock: 10” aluminum reservoirs provide generous oil and nitrogen volume for consistent damping as shock temperature increases\u003c\/li\u003e\n  \u003cli\u003eICON RXT Rear Shock: “ICON 1K” tested under rigorous off-road conditions to validate tune, performance, strength, and durability\u003c\/li\u003e\n  \u003cli\u003eICON RXT Rear Shock: Unique side-mounted lower eyelet allows for increased travel while utilizing factory mounting location\u003c\/li\u003e\n  \u003cli\u003eICON Hydraulic Rear Bump Stop Kit: Direct bolt-in to OEM bump stop location makes for an easy and straightforward install\u003c\/li\u003e\n  \u003cli\u003eICON Hydraulic Rear Bump Stop Kit: 2.5” travel bump stop reduces rear end ‘kick’ and improves overall performance\u003c\/li\u003e\n  \u003cli\u003eICON Hydraulic Rear Bump Stop Kit: Vehicle specific bump stop tune to provide smooth engagement and best ride quality\u003c\/li\u003e\n  \u003cli\u003eICON RXT Rear Shock: CDC Valve technology allows for 10 settings of quick and easy compression damping adjustment\u003c\/li\u003e\n  \u003cli\u003eICON Hydraulic Rear Bump Stop Kit: Position sensitive technology exponentially increases bottom-out resistance\u003c\/li\u003e\n  \u003cli\u003eICON RXT Multi-Rate Leaf Spring: Galvanized leaf separators reduce friction and aid in corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eICON RXT Rear Shock: Corrosion resistant, one-piece impact extruded aluminum shock bodies with 7\/8\" shafts\u003c\/li\u003e\n  \u003cli\u003eICON RXT Multi-Rate Leaf Spring: 3 user-adjustable spring rates for unique vehicle configurations\u003c\/li\u003e\n  \u003cli\u003eICON RXT Multi-Rate Leaf Spring: Direct bolt-in to OEM spring location makes for an easy install\u003c\/li\u003e\n  \u003cli\u003eICON RXT Rear Shock: Vehicle-specific tuned shocks provide increased damping and oil volume\u003c\/li\u003e\n  \u003cli\u003eICON RXT Multi-Rate Leaf Spring: Leaf tip inserts reduce noise and increase ride comfort\u003c\/li\u003e\n  \u003cli\u003eICON RXT Multi-Rate Leaf Spring: Military wrap front eyelet for increased durability\u003c\/li\u003e\n  \u003cli\u003eICON Hydraulic Rear Bump Stop Kit: Heavy duty 1.25” CNC machined nitro steel shaft\u003c\/li\u003e\n  \u003cli\u003eICON Hydraulic Rear Bump Stop Kit: CAD plated body for maximum corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eICON Hydraulic Rear Bump Stop Kit: Double sealed high pressure Schrader valve\u003c\/li\u003e\n  \u003cli\u003eICON Hydraulic Rear Bump Stop Kit: Replaceable noise-reducing striker pad\u003c\/li\u003e\n  \u003cli\u003eICON RXT Rear Shock: Shocks are fully rebuildable and revalveable\u003c\/li\u003e\n  \u003cli\u003eICON Hydraulic Rear Bump Stop Kit: Operating range of 50-250 PSI\u003c\/li\u003e\n  \u003cli\u003eICON RXT Rear Shock: Simple and straightforward installation\u003c\/li\u003e\n  \u003cli\u003eICON Hydraulic Rear Bump Stop Kit: Fully serviceable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe ICON K53156 RXT Stage 2 Rear Suspension System is engineered for 2007-2021 Toyota Tundra trucks seeking improved ride quality, suspension travel, and off-road performance. Developed through ICON’s “ICON1K” accelerated research and development program, this system was tested under demanding desert and expedition conditions to identify and address the limitations of original equipment components. The complete package combines ICON RXT multi-rate leaf springs, hydraulic rear bump stops, and vehicle-specific RXT 2.5 Aluminum Series rear shocks for a balanced suspension upgrade.\u003cbr\u003eThe RXT multi-rate leaf springs provide three user-adjustable spring rates to accommodate different vehicle configurations, cargo loads, and aftermarket equipment. When paired with the RXT shocks, the system can increase wheel travel by up to 20 percent without sacrificing available up-travel. Galvanized leaf separators help reduce friction and corrosion, while leaf tip inserts improve ride comfort and reduce operating noise. Military-wrap front eyelets add durability, and the leaf springs install directly in the original equipment mounting locations.\u003cbr\u003eThe hydraulic rear bump stop kit bolts directly into the factory bump stop locations for a straightforward installation. Its position-sensitive design improves bottom-out resistance and reduces rear-end kick, while vehicle-specific tuning promotes smooth engagement and controlled performance. The fully serviceable bump stops feature a heavy-duty 1.25-inch CNC-machined nitro steel shaft, corrosion-resistant plated body, replaceable noise-reducing striker pad, and an operating range of 50-250 PSI.\u003cbr\u003eThe RXT rear shocks use 10-inch aluminum reservoirs to increase oil and nitrogen volume for consistent damping as temperatures rise. CDC Valve technology provides 10 compression damping settings for quick adjustment, and the unique side-mounted lower eyelet increases travel while retaining the factory mounting location. Corrosion-resistant aluminum bodies, 7\/8-inch shafts, and fully rebuildable, revalveable construction support long-term serviceability. This system is recommended for use with 35-inch by 12.50-inch tires; larger tires may require fender trimming or additional modifications.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eICON RXT multi-rate leaf springs with three user-adjustable spring rates\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eUp to 20 percent more wheel travel when used with RXT shocks\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHydraulic rear bump stops with position-sensitive bottom-out resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDirect bolt-in installation using original equipment mounting locations\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVehicle-specific RXT 2.5 Aluminum Series rear shocks\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e10-inch aluminum shock reservoirs for consistent damping performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCDC Valve technology with 10 compression damping settings\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSide-mounted lower shock eyelets for increased suspension travel\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eGalvanized leaf separators for reduced friction and improved corrosion resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLeaf tip inserts for reduced noise and improved ride comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMilitary-wrap front leaf spring eyelets for added durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty 1.25-inch CNC-machined nitro steel bump stop shafts\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCorrosion-resistant plated bump stop bodies\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eReplaceable noise-reducing striker pads\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBump stop operating range of 50-250 PSI\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFully serviceable hydraulic bump stops\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFully rebuildable and revalveable rear shocks\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRecommended for 35-inch by 12.50-inch tires\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\nCompatible With\u003cbr\u003e\n2007 Toyota Tundra\u003cbr\u003e\n2008 Toyota Tundra\u003cbr\u003e\n2009 Toyota Tundra\u003cbr\u003e\n2010 Toyota Tundra\u003cbr\u003e\n2011 Toyota Tundra\u003cbr\u003e\n2012 Toyota Tundra\u003cbr\u003e\n2013 Toyota Tundra\u003cbr\u003e\n2014 Toyota Tundra\u003cbr\u003e\n2015 Toyota Tundra\u003cbr\u003e\n2016 Toyota Tundra\u003cbr\u003e\n2017 Toyota Tundra\u003cbr\u003e\n2018 Toyota Tundra\u003cbr\u003e\n2019 Toyota Tundra\u003cbr\u003e\n2020 Toyota Tundra\u003cbr\u003e\n2021 Toyota Tundra","brand":"ICON","offers":[{"title":"Default Title","offer_id":50543835185392,"sku":"K53156","price":3706.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/6242\/3792\/files\/ae2de14f6d12496b405d52acf43a3505.jpg?v=1790467147","url":"https:\/\/overlandgear.co\/products\/icon-k53156-rxt-stage-2-rear-suspension-system-for-2007-2021-toyota-tundra","provider":"Overland Gear Co","version":"1.0","type":"link"}
