BDS 6″ Performance Coilover Conversion Long Arm System

2003-2013 Dodge RAM 2500/2003-2012 Dodge RAM 3500 4wd trucks

Coldwater, MI— November 25, 2014— The engineers at BDS Suspension and Fox have teamed up once again with an exciting to release for the 2003-2013 Dodge Ram 2500 trucks. With the popularity of Fox coilover options on many 1/2-ton applications BDS has been developing and testing new coilover options for the 3/4-ton & 1-ton RAM diesel trucks. After more than a year in development we are excited to announce BDS is now shipping complete 6″ coilover conversion long arm systems and 6” coilover upgrade kits designed to take your RAM to the next level. These new kits are designed to improve vehicle performance across all terrains, allow you to soak up the bumps and out flex the competition all the while offering plush on-road comfort and predictable handling characteristics.

These new systems are designed around the tried and true BDS long arm system, feature a pair of massive subframe 4-link control arm brackets and oversized upper and lower formed long arms for improved stability, handling and overall performance. The arms are formed for maximum tire clearance and allow the stock control arm tabs to remain on the vehicle. The upper arms are solid stock while the heavy wall tubular lower arms utilize oversized greaseable polyurethane bushings for superior road vibration isolation.

The extra altitude comes from a pair of specially designed Fox 2.5 remote reservoir coil overs designed for the ultimate performance right out of the box. These Fox coilovers feature:

  • Smooth-bore and honed seamless alloy body
  • Black anodized 6061-T6 billet aluminum mounting components
  • 7/8″ heat treated steel carbon shaft
  • High flow piston design with specially formulated race oil
  • 3″ Eibach primary coil and tender coil allowing for 10” of coilover travel
  • 2.5″ smooth bore and honed seamless reservoir
  • Easy bolt-on installation, coil spring preload set for proper ride height right out of the box.

These coilovers are built to perform on the front of Cummins-powered RAMs and to install in place of the coil springs with the use of BDS’s new heavy duty upper and lower mounting brackets. These brackets not only create a sturdy top mount at the frame with room for the reservoir, but also include weld-in reinforcements at the axle able to continually perform under whatever abuse your RAM HD is subjected to.

These new coilover systems also address the steering with a heavy duty front track bar bracket and forged drop pitman arm to keep the steering in phase, extended sway bar links, brake line brackets, extended bump stops, billet aluminum machined front driveline spacer, your choice of rear block kit or replacement GlideRide leaf springs, brake line bracket, and Fox 2.0 rear performance gas shocks. As with all BDS lifts, these include Factory Protection Plus, combining BDS’s No Fine Print Warranty and 5-year 100,000-mile drivetrain protection plan for your RAM truck.

Available Accessories

For current BDS equipped Dodge Ram 2500/3500 trucks, the coilovers are also offered separately as an upgrade kit for the current coil spring equipped trucks that includes the mounting brackets and coilovers to retrofit any previously install BDS 6″ long arm system. Other accessories include BDS 5500, 9500, and Fox 2.0 steering stabilizer kits to improve dampened capability and reduce front end “shimmy” caused by oversized tires. Also available is an optional transfer case indexing ring and carrier bearing drop kit to help with driveline angles. BDS offers extended braided stainless steel brake lines for the front and rear, heavy duty adjustable front track bar and rear traction bars.
