1.25-Inch Triple Rate Rear Coil Spring Kit for Toyota Tundra

About this part

1.25-Inch Triple Rate Rear Coil Spring Kit, fitment-checked

Triple rate rather than dual — three stages of spring rate rather than two, which is an unusual specification and the whole reason to choose this over a simpler coil.

Coverage is the Toyota Tundra from 2022-2025 across 1794 Edition, Capstone, Limited and the rest of the range, giving 1.25 in. of rear lift. A dual rate spring is soft then firm; a triple rate adds a third stage, which gives a wider useful range between empty and fully loaded. On a truck that does both that is worth having. Lifetime warranty recorded — unusual on a spring kit, where ICON often splits the terms. 55 lb boxed.
