To develop this kit we worked closely with the people that matter the most, you guys! This was the first kit on the market to offer a complete bolt on RSK (reverse shackle kit) to use the Superduty springs on the OBS (old body style) trucks that required no frame or bumper modifications.
With this kit, you can bolt on our conversion hangers using existing holes in your frame and clear all factory bumper mounts and components. For trucks that are wanting to install an intercooler, we have designed the kit with optional bolt locations to allow proper clearance for most intercoolers. For this installation configuration, you will need to drill two additional holes per side.
The installation of this RSK kit will provide a noticeable improvement in ride quality. This is accomplished through the use of a longer Superduty spring and the relocation of the shackle to the rear of the spring. With that change, the truck is no longer fighting against itself when it hits bumps on the road. Instead, you will have a truck the drives and handles like a 1999-2004 F-250/350.
The kit is available in 3 different lift heights. This is the lift amount of the kit itself. Please keep in mind that depending on what code of Superduty springs are used, you may have additional lift amount. The kit comes complete with the front hangers and rear shackles and all needed assembly hardware. Superduty springs and spring eyelet bolts are not included.
The kit comes standard with a smooth square crossbar. This ties the two front hangers together and adds rigidity to the frame itself. The standard kits' crossbar is 1/8" wall thickness. If you choose to upgrade to tow hooks or a receiver hitch, we also upgrade the crossbar to 1/4" wall.
