BDS 4" Air Ride RAM 2500 Lift Systems: The latest addition to BDS Suspension's lineup for RAM trucks are new 4" lift options for the rear air ride equipped RAM 2500 4wd trucks.
Up front BDS Suspension offers (2) configurations of this lift kit; the standard radius arm drop bracket and the 4-link conversion. Both kits use a pair of diesel or gas specific progressive rate ProRide front coil springs for optimal performance across any terrain, heavy-duty fabricated track bar bracket and forged drop pitman arm to correct steering geometry, extended bump stops and sway bar relocation and brake line relocation brackets to keep the suspension functioning properly. The standard 4" system retains the factory front radius arms and corrects the suspension geometry by adding a pair of 1/4" steel frame-mounted drop brackets. The 4-link converts the factory radius arms over to a much stronger 4-link design for improved stability, handling and articulation. The 4-link limits caster change throughout wheel travel for much more predictable driving habits. It uses 1/4" steel brackets that key off the factory radius arm mounts for increased strength and use 2" OD x 3/16"-wall DOM control arms with large 2-1/2" OD polyurethane bushings for smooth, quiet operation. Rounding out the front is your choice of BDS-NX2 series or FOX 2.0 IFP gas shocks for improved performance.
In the rear both lift kits are designed to work with the factory rear air ride system. One-quarter inch steel, 3.5" tall gusseted air bag spacers are used along with a rear track bar bracket to correct axle positioning, extended length sway bar links, and bump stop extensions. BDS supplies new air ride leveling sensor brackets to position the ride height sensors at the stock angle. This allows the rear suspension to perform just like it does at factory ride height and maintain full air bag range of motion. The rear suspension is rounded out with your choice of BDS NX2 Nitro or FOX 2.0 performance gas shocks.
Along with these new systems, BDS offers several accessories including shocks and steering stabilizer kits, adjustable track bars, stainless steel brake lines and more. The 4" suspension systems allow for up to 37" tires to be installed. Upgrade your rear air ride equipped RAM 2500 with BDS Suspension.
