Overview
The 2007-2017 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'gineers 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" R&D 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 Series rear shock options. Installation of this system replaces the aforementioned "limiting factors" and completely redefines the potential of the 2007-2017 Toyota Tundra with a 20% increase in wheel travel and the ability to adjust the leaf spring rate to compensate for varying vehicle setups.
