🧾 Overview
The ICON Rear Triple Rate Coil Spring Kit is a performance-focused rear spring upgrade for 2022–2025 Toyota Tundra, designed to improve ride quality, load handling, and overall suspension control without significantly increasing ride height.
Using ICON’s triple-rate spring design, this kit provides a softer initial rate for comfort, a balanced mid-rate for daily driving, and a firmer overload rate to handle added weight or aggressive off-road use. This results in better ride quality on-road and improved bottom-out resistance off-road.
With approximately 0–0.5" of rear lift (application dependent), this setup is ideal for maintaining near-stock stance while improving performance—especially for trucks carrying gear like bed racks, tents, or recovery equipment.
✔ Triple-rate spring design for balanced comfort and performance
✔ Maintains near-stock ride height (0–0.5" lift)
✔ Improves load handling and rear-end support
✔ Reduces sag from added overland weight
✔ Designed to pair with ICON rear shocks
🛠 Installation
- Direct replacement for factory rear coil springs.
