Description
If you're looking for a suspension upgrade for your 2019+ Ram 2500, this system from BDS Suspension is built not only to give you additional lift but also additional performance. These kits have been engineered for improved on-road comfort and offroad capability. Kits include high strength tubular 4-link longarms, front and rear progressive rate coil springs, your choice of shocks, and steering correction, allowing clearance for up to 37" tires. As with all BDS Suspension systems these new 6" 4-link long arm systems are backed by Factory Protection Plus for peace of mind wherever you choose to explore. Up front these systems use a pair of 6" diesel specific progressive rate coil springs to provide the extra height and smooth controlled performance in the harshest of terrains. A forged drop pitman arm is supplied to correct steering angles along with a HD bar drop bracket to re-center the front axle. A pair of sway bar drop brackets reposition the OE sway bar for optimal performance along with extended polyurethane bump stops to limit up travel and brake line brackets to allow full droop. To correct the front suspension geometry at the new height the factory stamped steel radius arms are converted over to 4-link using a pair of 1/4" steel brackets and high strength upper and lower control arms designed to limit caster control throughout suspension travel for more predictable handling characteristics. Also supplied are your choice of BDS NX2 gas shocks or FOX 2.0 performance series IFP gas shocks for improved ride and performance. At 6" of lift it is critical to correct the front driveline angle to maintain use of the 4WD. To do this BDS Suspension provides a heavy duty replacement transmission crossmember as well as a transfer case indexing ring to reposition the front driveline output to allow use of the factory drivelines. In the rear of the RAM 2500 kits 4.5" progressive rate coil springs provides a level-to-slightly tail high stance while maintaining load capacity. Extended rear sway bar end links and new bump stops are included to compensate for the lift along with a track bar bracket to re-center the rear axle. Finishing out the rear are a matching set of BDS NX2 gas shocks or FOX 2.0 performance series IFP gas shocks. As with all BDS Suspension kits these include Factory Protection Plus for a limited lifetime warranty, ESC System compatibility, and 5-year, 100,000-mile drivetrain warranty. Get the look and the ride you are after with these new 4" radius arm systems from BDS Suspension. 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 Series - Need to kick your suspension up another notch? The FOX 2.5 Performance Elite Series greatly expands your off-road capabilities and how much punishment your shocks can take. Made with external reservoirs to keep your shock oil away from high stress and higher temperatures, the elite series shocks are part of a suspension that will handle whatever you throw at it. Comes with easy adjustments to switch between different terrains, load and speed. Dual Speed Compression Adjuster comes standard. 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! 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. Front Adjustable HD Track Bar 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 at the 1-3/8?-12 fine threaded center turnbuckle with pinchbolt 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 clearance 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 powdercoat finish for a great look and excellent corrosion resistance. The 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. Adjustable Rear Track Bar This new track bar allows for fine adjustment of the rear axle position. It also provides better control of the rear axle by replacing the soft factory rubber bushings with high durometer polyurethane at the frame and a forged COM bearing joint at the axle. Both ends are rebuildable and the poly bushings are greaseable. Can be used with or without track bar relocation when needed for heights of 0-8". Carrier Bearing Drop Kit 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. The kit comes with multiple shim plates for full adjustability from 1/8" to 1-1/2" of drop. Includes necessary hardware. For all 3"+ Lift Kits.

About BDS Suspension

BDS Suspension was started in 1996 by a business group who felt it was past time to create a suspension company that truly had the best interest of the off road consumer as its' foundation. With over 45 combined years experience with other major suspension companies, both buying and selling, the individuals that would make up the BDS name were frustrated by the lack of quality and the unwillingness to make things right by these 4x4 companies. So, they set out to create a suspension company that would be the best and made a list of the things they felt were not right and made it their mission to correct them.

One of the most important of these wrongs they were looking to right were that of other companies warranties. Too often, the standard protocol was that a broken or damaged part from another manufacturer was denied warranty because of abuse or neglect. For BDS, its simple, if it breaks, they'll replace it, and that is the motto in which they have based their entire warranty off of. So, they welcome you, try and break it, if you do, they'll replace it and probably try to determine a way to increase the rigidity of the product to ensure it never happens again.

BDS LIFT KITS

While most people whom have heard of BDS Suspension automatically think of "lift kits," that ony touches on the wide variety of suspension and steering related products that BDS offers. BDS understands that not everyone is after a complete lift kit, but still after the quality BDS products bring to the table. Some of our most popular products from BDS are replacement adjustable track bars and dual steering stabilizer kits that in many instances can be installed on a completely stock truck, or one that's leveled or lifted. Other popular "non lift kit" parts are leveling kits that include upgraded shocks, progressive rate coil springs, heavy duty control or radius arms, and even leaf springs.
