The Dirt King Fabrication Long Travel Kit is engineered to drastically improve off-road handling without sacrificing daily drivability. Built for performance and durability, this suspension system increases wheel travel, enhances articulation, and delivers superior control in demanding terrain.With 13.5” of wheel travel and clearance for up to 35” tires, this kit significantly upgrades your vehicle’s off-road capability. The upper and lower control arms feature 1” stainless steel uniballs at the outer pivots, replacing traditional ball joints for increased strength and articulation.Unlike many competitors, this kit retains the factory lower arm mounting location—resulting in improved ground clearance and optimized suspension geometry. CAD designed, thoroughly tested, and 100% made in the USA, this is a system built for serious off-road enthusiasts.
