2013-2018 Cummins 4" 4 Link Lift Kit (BDS697H)
Convert your Cummins away from the problematic factory radius arm suspension setup to the custom BDS Suspension 4-Link system. The design starts with 2 massive frame brackets that provide the mounting points for the new upper and lower control arms. These brackets locate off of the factory radius arm brackets, no factory bracket removal is required. The new 4-Link brackets mount is similar to the current radius arm relocation brackets, wrapping the frame and nesting in the factory radius arms mounts. As with the radius arm brackets, there is a minor amount of welding required to install the threaded frame insert (1 per side). This insert is necessary to provide the strongest possible mount.

BDS is now offering an HD adjustable front track bar for the RAM 2500 and 3500 trucks. These new track bars are a massive upgrade to the factory unit, constructed from 1-3/8 solid steel stock reinforced with gusseted ends to handle whatever on-road and off-road abuse you can through at it. Adjustments are made on the 1-3/8-12 fine threaded center turnbuckle with pinch bolt ends to allow easy tuning to properly recenter the front axle for a range of lift heights. The track bar is formed for proper clearance around critical front-end components and is designed to easy installation without the need to clear the factory frame and axle mounts. Both ends use high-durometer polyurethane bushings with thick-walled steel sleeves for strength and reliability. Parts come with a high-quality textured black powder coat finish for a great look and excellent corrosion resistance. They are designed for use on 0-3" of lift and can be used in combination with most aftermarket track bar brackets to be used on taller lift heights.
