RXT Rear Suspension Systems
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’ 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” 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.

ICON RXT Multi-Rate Leaf Spring
The backbone of the Tundra RXT Rear Suspension System is a user-adjustable multi-rate leaf pack that offers a major performance gain for almost every accessory & gear setup imaginable. Features like tip inserts and leaf separators reduce friction and increase ride comfort, while a military wrapped front eyelet improves the durability and strength of the leaf spring. To increase the ride quality of the truck and gain additional droop travel, the spring rate has been lowered slightly. While many Tundra owners will embrace this, there are those who have outfitted their trucks with a significant amount of weight in the form of a bed rack, roof top tent, spare tires, parts, or other additions. Taking this into consideration, the leaf pack was designed with an additional leaf (included with kit) that can be exchanged or added to the pack yielding an additional 15% or 25% in spring rate that will handle more "outfitted" vehicles.
ICON RXT Rear Shocks
To compliment the RXT Multi-Rate Leaf Spring, three new ICON shock options have been developed to control the suspension throughout this new range of travel. These include a 2.5 Series remote reservoir shock, a 2.5 Series CDC Valve shock, and a two-tube Omega bypass option – each of which provides unique levels of performance to the rear end of the Tundra. The increase in wheel travel was answered with a unique side-mount eyelet approach that allowed ICON engineers to develop a shock that is shorter in collapsed length, longer at extension, and still fits in the factory mounting location. A large ten inch remote reservoir was added to aid in heat dissipation and resist shock fade during spirited driving.

I have a 6" Procomp lift with icon big lift coilovers. Will the new RXT leaf pack take care of the rear block and be lever it high enough for the set-up?

I have seen customers use the RXT Leaf system to replace a 4" lift block. It will be difficult to gauge exactly the outcome of each configuration but if the goal is to replace a 4" the RXT system can be a good option.
