🧾 Overview
The ICON Stage 1 RTX Suspension System is a complete high-performance upgrade for 2007–2021 Toyota Tundra, designed to dramatically improve ride quality, control, and off-road capability—especially for heavier builds and more aggressive use.
This system pairs ICON’s 2.5" front coilover shocks with the advanced RTX rear suspension system, featuring multi-rate leaf springs and upgraded rear shock performance. The result is a major increase in wheel travel, improved load handling, and significantly better ride characteristics both on and off-road.
Engineered through extensive real-world testing, the RTX system addresses the limitations of the factory rear suspension—making this a serious upgrade for towing, overlanding, and high-speed off-road driving.
✔ Complete front and rear suspension upgrade
✔ Adjustable front coilovers for leveling and lift
✔ RTX rear system improves load handling and ride quality
✔ Increases wheel travel and overall suspension performance
✔ Ideal for overland, towing, and aggressive off-road use
