ICON Vehicle Dynamics K53155 Stage 1 RTX Rear Suspension System for Toyota Tundra

The ICON Vehicle Dynamics Stage 1 RTX Rear Suspension System represents a complete reimagining of Toyota Tundra rear suspension performance.

Complete System Components:

• ICON RXT Multi-Rate Leaf Springs with 3 user-adjustable spring rates

• Three RXT-specific 2.5 Aluminum Series rear shock options

RXT Multi-Rate Leaf Spring Features:

• Three adjustable spring rates accommodate varying vehicle configurations from unloaded to fully equipped
• Military wrap front eyelet design provides exceptional durability under extreme loads
• Galvanized leaf separators reduce interleaf friction and enhance corrosion resistance
• Optimized spring rate progression allows increased wheel travel without sacrificing up-travel
• Validated through hundreds of hours of testing in desert, trail, and expedition conditions

Application: 2007-2021 Toyota Tundra

This system replaces limiting factory components and transforms the Tundra's capabilities for high-speed desert running, technical trail navigation, and overland expedition use. The adjustable spring rate system allows tuning for different payload conditions, making it ideal for vehicles that transition between daily driving, heavy towing, and off-road adventure.
