ICON Triple Rate Overland rear coil springs are made for 2021–2025 Ford F-150 Raptor Gen3 applications and are tuned to net roughly 1" of rear lift when the rear carries about 300 lbs of additional weight. The triple-rate design blends a comfort-focused ride rate, an overload rate for load resistance and bottoming control, and an extra-soft initial rate for expanded droop travel, with long free height and a lifetime guarantee.
