The Dirt King Long Travel Suspension System is engineered to dramatically enhance off-road handling while maintaining excellent day-to-day drivability. Up front the system delivers 12” of travel and supports up to a 37” tire offering substantial improvements in articulation and clearance. Designed for both 2WD and 4WD models when paired with extended axle shafts. Compared to the competition we’ve gained several inches of ground clearance by mounting the lower arms in the factory location instead of below it. The system is fully CAD-designed, rigorously tested, and proudly manufactured in the USA.

In the rear the setup provides up to 17” of usable travel when combined with the Dirt King bedcage and Dirt King Long Travel Leaf Springs. Together the front and rear kits create a balanced, high-performance suspension package that transforms the vehicle’s capability without compromising reliability or everyday usability.

Options

This suspension system allows for several different options to suit your needs. The 2.5” x 8” coil over can be installed with one of the following options, sway bar, bump stops, or bypass shocks. We offer a sway bar kit that adapts our long travel kit to work with the factory sway bar. This will give the vehicle similar on road driving characteristics to stock with minimal sacrifice to the suspension systems performance. The next option is installing bump stops. They will help dampen hard impacts and are cost effective but on the other hand are often noisy. The last option is most commonly used. Adding bypass shocks will fine tune the damping throughout the suspension cycle. They are also completely adjustable to perfect the ride quality.

Shocks

For the best performance and to achieve the full amount of travel you must purchase our spec built coil over shocks or have them custom built based on our shock spec sheet. In addition, our long travel kit is tabbed to accommodate bypass shocks. The bypass shocks will allow for superior suspension dampening and tunability. To mount the bypasses we offer a weld on bypass shock hoop kit (DK-631910) that can be purchased separately. The bypass shock hoop kit requires welding and modifications to the frame. You have the option of installing 2.5” diameter by 8” stroke bypass shocks or 3.0” diameter by 8” stroke bypass shocks.

Wheel Travel

When shopping long travel kits many consumers tend to focus just on travel numbers. This is the reason many companies claim inaccurate numbers or don’t disclose the amount of work involved to achieve these numbers. Our goal is to build a suspension system with the highest amount of wheel travel without requiring major modifications to the vehicle or compromising its overall drivability.

Tire Info

When installing 37” tires with this kit you must modify the wheel wells to avoid contact at full bump. We have solved this problem by developing complete bolt on front wheel wells for proper tire clearance. The firewall pinch weld will also need to be folded over to clear the 37” tires.
