Coldwater, MI: BDS Suspension expands its listings for the late model 2019+ RAM 3500 4WD Diesel trucks with new 3” radius arm systems that are on the shelf ready to ship. Designed to improve the looks and performance of your new RAM, these kits include everything necessary to correctly lift them for improved offroad capability with room for larger tires while maintaining on-road handling.

Up front these systems use a pair of (diesel specific) progressive rate 3" coil springs to provide the extra height and offer controlled performance in the harshest of terrains. A high strength adjustable track bar with center pinch-bolt turnbuckle is supplied to re-center the front axle. A pair of extended length sway bar links correct the OE sway bar operating angle 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 a pair of heavy duty replacement radius arms that bolt directly into the factory location. These new radius arms are massive upgrade to the factory stamped units, using tubular construction and a lower cam adjustment to dial in front end caster. Also supplied are your choice of BDS NX2 gas shocks or FOX 2.0 performance series IFP gas shocks for improved ride and performance.

In the rear of the RAM 3500 kits a pair of 2" steel fabricated lift blocks and extended u-bolts are used to provide a level to slightly tail high stance while maintaining load capacity. 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 3" radius arm systems from BDS Suspension.
