6" 2013-2018 Dodge Ram 3500 4WD (w/diesel engine) 4-Link Lift Kit by BDS Suspension

The BDS Suspension BDS1603H / BDS1603FS 6-inch 4-link lift kit for the 2013 through 2018 Dodge Ram 3500 is an excellent way to upgrade your suspension and fit up to 37-inch tires. The design for these kits 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, a minor amount of welding is required to install the threaded frame insert (1 per side). This insert is necessary to provide the most robust 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 can 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.

The new front coil springs are progressive rate 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 a 4-inch, 5-inch block or Glideride rear leaf springs. 

Choose from Fox 2.0 Performance IFP Shocks (2-inch diameter aluminum body monotube gas), BDS NX2 Shocks (Nitro Gas), or Fox 2.5 Performance Elite Adjustable Shocks (2.5-inch diameter aluminum body with ride adjustment knobs), which are included for the front and rear.
