8″ BDS 4-Link Systems for RAM 3500 Trucks

BDS adds to its suspension lineup with new lift kits for the 2013-2015 RAM 3500 4WD Diesel Trucks. Adding to the current lineup of 2″ leveling, 3″ radius arm, 4-6″ standard, and 4-6″ 4-link systems are new 8″ 4-link systems. While the 8″ 4-link with full spring replacement has been available, BDS now offers a block and dual add-a-leaf option giving RAM 3500 owners a more affordable option to get clearance to fit up to 40″ tires. This new kit utilizes the tried and true 4-link front suspension engineered to improve the trucks handling in any terrain while limiting caster change through wheel travel. As with all BDS kits, this new 8″ 4-link system is backed by Factory Protection Plus (FPP) giving you the piece of mind to use it and abuse it wherever your next adventure may be. FPP combines BDS’s No Fine Print Lifetime Warranty and a 5-year 100,000-mile drivetrain warranty.

Factory Protection Plus
  • 5-year, 100,000 mile drivetrain warranty
  • BDS’s exclusive No Fine Print Warranty

BDS Suspension continues to lead the industry with new and innovative products for the late model RAM 2500/3500 4WD trucks. In addition to the 2″, 3″, 4″, 6″ and 8″ full spring kits BDS now offers the 8″ with a 5″ block and dual add-a-leaf option giving truck owners a more affordable option lift and level the stance with room for up to 40″ tires.

This 8″ 4-link system offers premium on-road comfort and superior offroad capability for the best all around performance out of your new 1-ton RAM. As with the widely popular BDS 4″, 6″, and 8″ 4-link conversion systems for late model RAM, this new 8″ system converts the factory radius arm suspension to a true 4-link for improved stability, wheel travel, and handling across all terrains. The 4-link design limits caster change to less than 1-degree of change throughout wheel travel for better handling, steering control, and overall driveability. The heart of the system are a pair of massive frame-mounted brackets precision welded and engineered to position the new upper and lower control arms for optimal suspension geometry for late model RAM trucks. The 4-link brackets are fabricated from 1/4″ thick steel and wrap around the frame as well as the factory radius arm brackets to create an extremely sturdy mount for the new arms. Removal of the factory radius arm brackets is not required allowing the brackets to stay intact to speed up the installation time. The upper and lower control arms are built from 2″ OD x 3/16″ wall DOM tubing for the strength to take any abuse you can throw at them. They utilize large 2.5″ OD polyurethane bushings to isolate road vibrations and are formed inward to allow for extra tire clearance. These arms are finished in a durable textured black powder coating and use grease fittings for easy servicing.

The additional height comes from a pair of specially designed dual rate ProRide coil springs. These 8″ coils have been engineered and tested to improve the ride quality and performance across all terrains while holding up to the rigors that 1-ton truck owners demand without bowing or sagging over time. A heavy duty track bar relocation bracket is supplied to recenter the front axle once lifted and a forged drop pitman arm is used to correct steering angles to keep them in phase for proper handling. New extended sway bar links are included to correct the front sway bar operating angle. These new links are greasable via pre-installed grease fittings and feature a unique poly-flex ball design to provide bind-free operation. Extended front bump stops are included to limit suspension compression and braided stainless steel kevlar-lined extended front brake lines allow full droop of the suspension. Rounding out the front are your choice of specially valved BDS-5500 or Fox 2.0 performance gas shocks for a smooth ride across any terrain.

At 8″ of lift, transmission/transfer case relocation is required to allow front driveshaft functionality. BDS includes a new laser cut transmission crossmember and adjustable transmission mounting plate to increase clearance front driveline clearance. The transfer case is repositioned by way of a supplied indexing ring kit to correct the operating angle and a billet aluminum driveshaft spacer is supplied to allow the use of the factory driveshafts. Indexing rings are available for both 6-bolt and 8-bolt transmission equipped trucks, confirm transmission before ordering. In the rear, BDS offers to options to lift the truck and level the stance. First is a new leaf spring + 2″ block combo and the other is a 5″ block + dual add-a-leaf kit.  The leaf spring option is designed to optimize ride quality and maximize wheel travel with a triple-stage leaf spring. The block and dual add-a-leaf is designed increase towing capacity by adding a pair of leafs to the factory spring pack. New rear u-bolts are supplied with both kits to convert the factory 14mm over to the larger 5/8″ diameter u-bolts and your choice of BDS-5500 or Fox 2.0 performance gas shocks complete the rear of this truck.

Available Accessories

BDS has a number of accessories available to fit the new 2013-2015 RAM 3500 trucks. Both single and dual steering stabilizer kit are available to meet your on-road and off-road performance needs. Available with 5500-series (white body), 9500-series (brushed stainless body), and Fox 2.0 (50/50-valved aluminum body) BDS steering stabilizers improve drivability by reducing front end shimmy caused by oversized tires and mount above the tie-rod for extra protection when offroad. The dual stabilizer kits mount end-to-end with an attractive BDS branded center bracket. In addition to steering stabilizers, BDS offers a heavy duty adjustable front track bar to allow you to dial in the front axle lateral positioning. Constructed from 1-3/8″ solid steel stock this new adjustable track bar is built to handle on and off-road abuse and uses a 1-3/8″-12 fine threaded pinch bolt design turnbuckle 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 features gusseted ends for additional rigidity. The ends utilize high-durometer polyurethane bushings with thick-walled steel sleeves for strength and reliability. To improve dampening capabilities BDS offers front dual shock mounting brackets. The upper hoop ties into the factory coil bucket and frame rail for added rigidity and allows you run a pair of BDS-5500 or Fox 2.0 shocks at each front corner. Lastly, BDS offers rear traction bar kits to fit the new Ram 3500 trucks. Designed to eliminate axle wrap and keep the rear axle planted during hard acceleration, BDS traction bars are constructed from 1-1/4″ OD tubing and are 100% bolt-on. As with all BDS products these are backed by the comprehensive Factory Protection Plus Plan.
