Icon Vehicle Dynamics | '07-21 Toyota Tundra RXT Rear Suspension Systems
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 the limits 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.
ICON RXT 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.
ICON Hydraulic Rear Bumpstop Kit:
The job of the bump stop is to control and limit the final position of the suspension during up-travel. The factory rubber bump stops have a limited energy absorption capacity and an uncontrolled release of this energy upon rebound – translating into a harsh ride and poor handling during more aggressive driving in rough terrain. ICON’s Tundra Rear Bump Stop Kit absorbs and releases this energy in a much more controlled manner resulting in predictable handling and vehicle dynamics. Like all ICON hydraulic bump stops, these feature velocity sensitive technology which means that as the shaft speed increases the damping ability ramps up to provide excellent bottoming resistance that won’t negatively affect articulation.
ICON 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.
