About this kit
6-Inch Lift Kit with Vertex Coilovers for F-250 4WD (2015–2016), fitment-checked
Rough Country 54259 is a 6-inch lift kit for the 2015–2016 Ford F-250 Super Duty 4WD in XL, XLT, Lariat, King Ranch, and Platinum trims. The kit pairs adjustable Vertex 2.5 front coilovers with Vertex 2.5 rear shocks, upgraded radius arms, and fabricated rear blocks with U-bolts. It does not fit F-350, dually, or gas-engine trucks.
This 6-inch lift kit for the 2015–2016 Ford F-250 Super Duty 4WD converts the front to adjustable Vertex 2.5 coilovers, left and right, and adds matched Vertex 2.5 rear shocks. Two radius arm boxes supply heavy-duty arms with rubber bushings that hold factory angles, and an axle-end alignment cam lets you set caster after the lift. Out back, fabricated anti-axle-wrap blocks and a U-bolt kit handle the rear height. Assembly is bolt-on. Confirm your truck is not an F-350, dually, or gas-engine model, then work through the downloadable Rough Country installation guide before you start.
