      The Dirt King long travel kit was developed to drastically improve the vehicles off-road handling without compromising its day to day driving characteristics. This suspension system allows for 13” of travel and accepts up to a 37” tire. The kit is compatible with 2WD models and 4WD models along with the purchase of extended axle shafts. Dirt King’s upper and lower arms are designed with 1” stainless steel uniballs for the outer pivots instead of ball joints for strength and increased articulation. The lower arms have recessed shock mounting allowing 8" coil overs to fit without any modifications. This kit is CAD designed, thoroughly tested, and sure to exceed expectations!

      This suspension system is for models that came stock with cast steel upper and lower control arms. If your vehicle has cast aluminum or stamped steel upper and lower control arms you must purchase DK-635908-B.

      *Please contact us if you plan on installing this kit with lift spindles or a bracket lift.

      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. 

      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.

      1. Installing a long travel kit can be very time consuming and require specialty tools and minor fabrication. Since the kit will likely be used under harsh conditions Truck Brigade recommends having an expert do the installation. Each kit comes packaged with easy to read instructions and illustrations to ensure a hassle-free installation.
