Description 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 13” 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 16” of usable travel when combined with the Dirt King bedcage and Deaver R81 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. Specifications Front Wheel Travel: Up to 13" Rear Wheel Travel: Up to 16" Amount of Lift: 0-4” Track Width: 3.5” wider per side Maximum Tire Size: 37” Maximum Backspacing: 4.75” Minimum Rim Size: 17” Coilover Shock Size: Fox Spec Spec Coilovers ShocksFor the best performance and to achieve the full amount of travel you must purchase our spec built shocks or have them custom built based on our coil over spec sheet. Our long travel kit is also 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-636710) that can be purchased separately. The bypass shock hoop kit requires welding and modifications to the frame. For extreme off-roading the kit has the ability to accept bump stops along with the coil overs and bypasses. The use of bump stops will alsorequire welding and modifications to the frame.
