2.5-Inch Front Component Box with Coil Springs, Ford Super Duty

2.5-Inch Front Component Box with Coil Springs, Ford Super Duty, fitment-checked

Coil springs and a track bar bracket rather than spacers: the more thorough route to 2.5 in. on a Super Duty front end. The only exclusion recorded is the Tremor trim package.

Raising a solid front axle pulls it sideways on the arc of its track bar, which is why this box includes a relocation bracket alongside the coil springs. Replacing the spring rather than spacing it also changes the rate, which suits a truck that carries weight over the front. Coverage is the 2017-2025 F-250 and F-350 Super Duty in 4WD: a nine-year window. The Tremor trim package is excluded. This is the component box; the same range offers versions with shocks bundled.
