What is the ICON1K R&D program?

The ICON1K R&D program is an accelerated testing process where ICON pushes vehicles to extreme off-road conditions for over a year. This helps them identify limiting factors in stock components and refine the performance of their own suspension systems.

What does 'multi-rate leaf spring' mean for my Tundra?

A multi-rate leaf spring uses different spring rates within the same spring pack. This allows the suspension to react differently to various impacts, providing a more compliant ride over small bumps and firmer support during larger compressions or when carrying loads.

Product Details

ICON's RXT Rear Suspension System starts with a unique multi-rate leaf spring design, developed through over a year of rigorous testing in their ICON1K R&D program. This program pushed Tundras to their off-road limits to pinpoint weaknesses in stock components and unlock more performance. The goal was to create a system that offers a better ride for everything from fast desert runs to remote expeditions.

This Stage 2 system includes the multi-rate leaf springs, a hydraulic rear bump stop kit, and your choice of three specific 2.5 Aluminum Series rear shocks. By replacing the factory limitations, this setup completely changes what your 2007-2021 Toyota Tundra can do off-road. You'll see a 20% increase in wheel travel, and the adjustable leaf spring rates let you fine-tune the suspension to match different vehicle loads and setups.

This is a comprehensive upgrade designed to significantly enhance your Tundra's off-road capability and on-road comfort. It's a well-built system that addresses the core components limiting your truck's potential, offering a substantial improvement for serious off-road use.
