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 TOYOTA TUNDRA RXT STAGE 1 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 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 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 K53155 RXT Stage 1 Rear Suspension System is engineered for 2007-2021 Toyota Tundra models seeking improved ride quality, suspension control, and off-road capability. Developed through ICON’s ICON1K accelerated testing program, this system was evaluated in demanding desert and expedition environments to address limitations in factory rear suspension 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 setup designed to handle high-speed off-road driving and varying vehicle configurations.\u003cbr\u003eThe RXT multi-rate leaf springs can provide up to 20% more wheel travel than stock when paired with the RXT shocks, while preserving useful up-travel. Three user-adjustable spring rates allow the suspension to be tailored for different vehicle builds, cargo loads, and equipment. Galvanized leaf separators help reduce friction and resist corrosion, while leaf tip inserts improve ride comfort and reduce operating noise. Military-wrap front eyelets enhance durability, and the direct bolt-in design uses the factory spring locations for a straightforward installation.\u003cbr\u003eICON’s hydraulic rear bump stop kit adds position-sensitive bottom-out resistance and is tuned specifically for the Toyota Tundra. The 2.5-inch travel bump stops help reduce rear-end kick and improve suspension control during harsh compression events. A heavy-duty 1.25-inch CNC-machined nitro steel shaft, corrosion-resistant CAD-plated body, replaceable striker pad, and double-sealed high-pressure Schrader valve support long-term serviceability. The bump stops operate from 50 to 250 PSI and bolt directly into the factory bump stop locations.\u003cbr\u003eThe included RXT rear shocks use 10-inch aluminum reservoirs to provide increased oil and nitrogen volume for consistent damping as temperatures rise. Their side-mounted lower eyelets help maximize suspension travel while retaining the factory mounting location, and the fully rebuildable, revalveable design supports future tuning and servicing. The system is recommended for use with 35-inch by 12.50-inch tires; larger tires may require fender trimming or additional vehicle modifications.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned for 2007-2021 Toyota Tundra applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProvides up to 20% increased wheel travel when used with RXT shocks\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes ICON RXT multi-rate leaf springs with three user-adjustable spring rates\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes vehicle-specific hydraulic rear bump stops with 2.5 inches of travel\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes RXT 2.5 Aluminum Series rear shocks with 10-inch aluminum reservoirs\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eICON1K tested for off-road performance, strength, durability, and tuning\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDirect bolt-in installation at factory spring and bump stop locations\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSide-mounted shock lower eyelets increase travel while using factory mounting locations\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePosition-sensitive bump stops improve bottom-out resistance and reduce rear-end kick\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eGalvanized leaf separators reduce friction and help resist corrosion\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLeaf tip inserts reduce noise and improve ride comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMilitary-wrap front eyelets improve leaf spring 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\u003eCAD-plated bump stop bodies provide corrosion resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDouble-sealed high-pressure Schrader valves\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eReplaceable noise-reducing striker pads\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFully serviceable hydraulic bump stops\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 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":50543831744752,"sku":"K53155","price":3401.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/6242\/3792\/files\/fc553b52a06488d9d87633b87499fb70.jpg?v=1790467068","url":"https:\/\/overlandgear.co\/products\/icon-k53155-rxt-stage-1-rear-suspension-system-for-2007-2021-toyota-tundra","provider":"Overland Gear Co","version":"1.0","type":"link"}
