4" 2014-2018 Dodge Ram 2500 4WD 4-Link Lift Kit by BDS Suspension

This BDS Suspension 1602H / BDS1602FS 4-inch 4-link lift kit for the 2014 through 2018 Ram 2500 replaces the factory radius arm setup with a 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 are located off of the factory radius arm brackets; no factory bracket removal is required.

The new 4-Link brackets mount similarly to the current radius arm relocation brackets, wrapping the frame and nesting in the factory radius arm mounts. As with our 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. The new control arm positions at the frame create better suspension geometry and reduce caster change through wheel travel compared to the radius arm setup. This creates better handling and more controlled steering "feel", especially in rough terrain when the suspension is allowed to travel and articulate. The large diameter, heavy-wall tubular control arms are formed for tire clearance when turning and position the axle slightly forward from stock to create more clearance to the rear portion of the front fenders.

Also included are new front coil springs that are progressive rate in order to provide excellent on-road ride and off-road performance. Track bar relocation, a dropped pitman arm, and brake line relocation round out the front portion of the system.

The rear is lifted via coil springs.  A rear track bar relocation bracket keeps the axle centered, and sway bar endlinks keep the proper operating sway bar angles.
