Superlift 23-24 Ford F-250 4in King Radius Arm Kit

Superlift's 4-inch radius arm lift kit pairs their suspension engineering with King shocks for the 2023-2025 Ford F-250 and F-350 Super Duty. This kit is built for 4WD diesel trucks and includes King front coilovers along with rear reservoir shocks, which is a combination that balances on-road comfort with off-road capability.

At the core of the lift are HD radius arms made from quarter-inch wall DOM tubing. These arms allow caster adjustment, which is important because lifting a truck changes the front suspension geometry and can create steering wander if the caster is not corrected. The engine-specific coil springs are tuned to account for the weight of the diesel powerplant, so you get a level stance rather than nose-heavy sag. Superlift states this kit clears 37-inch tall tires, which opens up a meaningful jump in tire size from the factory fitment.

One important compatibility note: this kit will not work with the auto-leveling headlight function found on some F-250 and F-350 trim levels. If your truck has that feature, it will need to be disabled or may not function correctly after the lift is installed. Superlift has been building lift kits since 1975, and this kit reflects their focus on ride quality both on pavement and off it.
