07-21 TUNDRA RXT STAGE 1 SYSTEM
2007-2021 TOYOTA TUNDRA RXT STAGE 1 SYSTEM
The 2007-2021 Toyota Tundra is a very capable and versatile truck with features that make it suitable for use as everything from daily driver, to tow rig, to adventure vehicle and everything in between.
From the brutal deserts of the Southwest to the wooded trails of the East coast ICON suspension systems have been put to the test and performed flawlessly for this popular Toyota.
Over the span of hundreds of hours in the shop and over a thousand miles in the dirt, ICON Vehicle Dynamics’ engineers have pushed this vehicle to extremes in order to develop the most sophisticated suspension components on the market.
Unable to leave “well-enough” alone, ICON is aiming to raise the bar in Tundra performance with the introduction of the RXT Rear Suspension System.
Through an accelerated testing process dubbed the “ICON1K” RandD program, ICON has spent over a year pushing the Tundra to off-road extremes to identify limiting factors in OE components and further extrapolate performance out of this vehicle.
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.
ICON RXT Multi-Rate Leaf Spring: 3 user-adjustable spring rates for unique vehicle configurations
ICON RXT Multi-Rate Leaf Spring: Military wrap front eyelet for increased durability
ICON RXT Multi-Rate Leaf Spring: Galvanized leaf separators reduce friction and aid in corrosion resistance
ICON RXT Multi-Rate Leaf Spring: Leaf tip inserts reduce noise and increase ride comfort
ICON RXT Multi-Rate Leaf Spring: Potential for increased wheel travel when used with RXT shock without sacrificing up-travel (up to 20% over stock)
ICON RXT Multi-Rate Leaf Spring: “ICON 1K” tested under rigorous off-road conditions to validate tune, performance, strength, and durability
ICON RXT Multi-Rate Leaf Spring: Direct bolt-in to OEM spring location makes for an easy install
ICON RXT Rear Shock: Unique side-mounted lower eyelet allows for increased travel while utilizing factory mounting location
ICON RXT Rear Shock: Vehicle-specific tuned shocks provide increased damping and oil volume
