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 either high strength tubular 4-link longarms or heavy duty tubular radius arms, front and rear progressive rate coil springs/ar bag spacers, your choice of shocks, and steering correction, allowing clearance for up to 37" tires. As with all BDS Suspension systems these new 4" systems are backed by Factory Protection Plus for peace of mind wherever you choose to explore. Up front these systems use a pair of diesel specific progressive rate 4" 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 4" of lift it is critical to correct the front driveline angle to maintain use of the 4WD. To do this BDS Suspension povides 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 2.5" progressive rate coil springs (if equipped)  or air bag spacers are supplied to level out the stance and improve capability across all terrains without affecting 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 Choose between custom valved BDS NX2 series or Fox 2.0 series gas charged monotube shocks to outfit the front and rear of your Ram. BDS NX2 Series - 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. This results in: increased stability for improved handling, longer front end and tire life, less nose dive on severe braking, less squat on hard acceleration, smoother ride control without harshness. Fox 2.0 Series - 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 to every BDS Suspension system. The basic shock design is based on proven Fox Racing Shox race products, but re-designed to maximize the ride quality, handling, and control of your BDS equipped truck or jeep, whether on or off the road. 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. Carrier Bearing Drop Kit 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.
