About this kit
6-Inch Lift Kit, fitment-checked
Wheel diameter is a hard requirement here: the supplied knuckle needs wheels of 20 inches or larger to clear. Vertex 2.5 adjustable coilovers and aluminum knuckles come with the kit.
Before anything else, check the wheels — the knuckle supplied with this kit requires a diameter of 20 inches or more for clearance, so a truck on smaller wheels needs new ones as part of the job. The kit itself carries Vertex 2.5 adjustable coilovers and aluminum knuckles. The exclusions are broad: single cab trucks, two-piece driveshafts, continuous control damping, Tremor models on their 1-inch factory lift, and the 3.0L Power Stroke Turbo Diesel V6 on motor weight. Cutting and drilling required. Shipping weight: 247.75 lb.
