ICON Triple Rate rear coil springs for 2021-2024 Ford F-150 Raptor provides a modest increase in ground clearance while greatly enhancing on- and off-road performance, especially when used with ICON shocks and suspension components. The triple-rate coil design combines a performance ride rate for compliance and comfort, with an overload rate for load and bottom out resistance, and an extra soft initial rate for maximum droop travel. A unique tapered wire design helps achieve maximum travel and efficiency and an extra-long free height ensures the coils stay seated in their coil buckets for up to 17” of droop travel. In addition, these springs are also designed to net 1" of rear lift on a stock weight Gen3 Raptor for a more aggressive stance and increased fender clearance for larger wheels and tires. Like all ICON coil springs, these feature a lifetime guarantee against sagging/breakage to provide confidence in knowing that you have the best suspension products available for the 2021-2024 Ford F-150 Raptor.
