Coldwater, MI: BDS Suspension expands its listings for the late model 2019+ RAM 2500 4WD trucks with new 4-6” 4-link conversion systems that are on the shelf ready to ship. Designed to improve the looks and performance of your new RAM, these new kits join existing radius arm variants to offer improved strength and handling on/off-road. Kits include everything necessary to correctly lift them for improved offroad capability with room for larger tires while improving overall vehicle handling.

Up front these systems use a pair of progressive rate coil springs (4"/5.5" gas) or (4"/6" diesel) 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 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 progressive rate coil springs 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 4-6” 4-link systems from BDS Suspension.
