These front coil springs give the 4WD diesel F-450 and F-550 about 2.5 in of lift. That is enough to fit larger tires, and when paired with ICON shocks it also allows more wheel travel. The springs are dual rate, designed with the weight of a diesel engine in mind.
A dual rate spring starts soft, which keeps the truck comfortable on the road, then firms up as it compresses. That second rate is what resists bottoming out and helps off-road. Caster correction cams are included so the alignment can be brought back in line at the new ride height.
Fitment
2005-2026 Ford F-450 and F-550 Super Duty, 4WD, diesel. The rate is tuned for diesel trucks, so it is not listed for gas engines.
What's included
Front coil springs and caster correction cams. ICON backs its coil springs with a lifetime guarantee against sagging and breakage.
Install notes
Lifting a Super Duty changes caster, so plan on an alignment after the install.
Questions before you order?
Fitment questions are easier to settle before the box ships. Call or text Carl & Anton at (920) 249-7744 or use the chat — real humans in Sheboygan, Wisconsin, not a call center.
