Quick Ship SKU #: BDS-1604-main BDS Suspension 6" 4-Link Lift Kit 14-18 Ram 6.7L Cummins 2500 4WD

Really need some heavy lift? The experts at BDS designed this kit to not only lift your Ram truck 6 inches but also get a better stance,  performance, and stability out of it. How do they do this? BDS replaced the factory radius arm setup for a 4-link system which optimizes suspension geometry for better handling. Plus, their distinctive look will make you stand above, both actually and figuratively, the competition.  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 preventing removal of the factory brackets.

The new 4-Link brackets mount similar to the current radius arm relocation brackets by wrapping the frame and nesting in the factory radius arms mounts.  As with 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 a 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. They also position the axle slightly forward from stock to create more clearance to the rear portion of the front fenders.

With this kit, BDS designed massive Pro-Ride Coil Springs that can handle a smooth predictable ride no matter the road conditions and how much you are hauling. Just choose a brand of shocks and necessary accessories before you kick yourself for not buying this kit earlier.

Shock Options:

• NX2 Nitro Series Shocks - BDS NX2 series gas shocks offer impressive performance on and offroad. They use a nitrogen-charged, twin-tube design with 10-stage velocity-sensitive valving for lightning-fast dampening and superior control.
• FOX 2.0 Performance Series Shocks - Fox 2.0 performance series shocks have been tuned and tested by both FOX and BDS Suspension to maximize performance specific to each application and every BDS Suspension system. The Internal Floating Piston (IFP) shock design is based on proven Fox Racing Shocks race products but re-designed to maximize the ride quality, handling, and control of your BDS-equipped truck, whether on or off the road.
• FOX 2.5 Performance Elite Shocks - For next-level performance, FOX has developed the 2.5 Performance Elite Series. These shocks are ready straight out of the box as they are tuned specifically for the BDS suspension systems. These 2.5" diameter shocks are ready to run through a wall for you with race-proven technology. Equipped with a remote reservoir for additional fluid capacity, it keeps heat down through the system. DSC Adjuster is controlled with a twist of either two knobs giving you 10 low-speed and 12 high-speed compression levels so you can be ready every time.

Steering Stabilizer Options:

• Single NX2 Nitro:Are you worried about your steering control? NX2 Nitro Steering Stabilizer is designed to be a high-end performance shock at an affordable price. Built with a durable metallic finish, a large fluon-banded piston, and self-lubricating seals this stabilizer is tough enough to last but tuned with vehicle-specific valving to give you amazing control. Built with both the morning commute and some light off-roading in mind, keep stress out of your steer and install one of these today!
• Single FOX 2.0 IFP Performance Series: The FOX 2.0 IPF Performance Series Steering Stabilizer is made from the same base components as the 2.0 performance series shocks and is properly valved and pressurized to be the ultimate stabilizer. Internal IFP mono-tube reservoir gives superior handling on top of increased durability.
• Dual NX2 Nitro Series: Is one not enough? Then upgrade to a dual steering stabilizer setup which gives further enhanced vehicle control and lessens side-to-side motion to a greater effect. Heavy off-roading requires a heavy suspension that can handle it but can still be smooth on asphalt.
  
• Dual FOX 2.0 Performance Series: Taking things even further is the dual FOX 2.0 setup. Built to last from the top up this performance setup will enhance control, reduce shimmy and bump steer, and improve tire wear and front-end component life. Protect your investment and smooth out your rough spots before they leave you figuratively hanging.

Carrier Bearing Drop Kit Option:

A 2-piece rear drive shaft will require some extra work as the geometry of your drive system will now have some added stress. We recommend adding this carrier bearing drop to avoid any potential driveline vibration with the added lift height.

Adjustable Track Bar Option:

When installing a lift kit, it's important to keep the correct geometry for your axle and the rest of the suspension system. If you don't, you will be adding extra stress where you don't want it and it can start to wear down your bushing, ball joints, and control arms. Use an adjustable track bar to keep proper alignment by centering the axle and giving you better handling on top. Choose a front, rear, or both trackbars as needed.
