ICON triple‑rate rear coil springs for 2022–2025 Toyota Tundra deliver a vehicle‑specific lift: about 1.25" rear lift on non‑TRD models or 0.75" on TRD‑equipped trucks, while improving ride and off‑road performance. The triple‑rate design balances softer droop and ride rates with a firm overload rate for bottoming resistance, and the springs carry a lifetime guarantee against sag and breakage.
