These new 3.5" lift kits allow for wheel and tire combinations up to 37" while keeping the smooth OEM ride and drivability. This is a complete lift kit includes 4" OEM-equivalent rear blocks with integrated bump stop landings, 3.5" coil spring extensions with sound isolators, an OEM-style panhard drop bracket, front bump stops OEM shock extension brackets, a pair of radius arm drop brackets, and all needed hardware. When used with the maximum size tires, the F250 truck body is raised over 6". ReadyLIFT Smart Suspension Technology is used to make this kit very user-friendly to install, requiring no cutting or drilling. Like all other ReadyLIFT kits, the F250/F350 3.5" SST Lift Kit is guaranteed for life against manufacturing defects.

  • When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality
  • When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 8-ply (or more) E tires compared to typical OEM 6-ply C tires
  • This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness
  • The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant
  • Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience

  • Use of this type of air bag system will void all block warranties and can cause failure of the block bump stop tang
