BDS Suspension 8" Performance Coil-Over System for the 2008 Dodge 2500 3/4 Ton & 3500 1 Ton 4WD Pickup including Mega Cab. BDS Performance Series Systems feature Fox 2.5 Reservoir Coilovers. These systems were designed specifically to combine the high-performance characteristics of the Fox 2.5 coilovers and BDS long arm suspension systems to create the ultimate 8" suspension system. The Fox coilovers are preset to achieve 8" of lift right out of the box and tuned for an amazing ride on and off road. In order to install the coilovers, we have developed a mounting system that bolts directly to the factory coil mounts with only minor trimming/drilling required. This new system not only creates a sturdy mount at the frame, it also includes weld in reinforcements at the axle - something other "bolt-on" mounting kits on the market do not address. The coilovers along with the mounting system can be purchased separately to retrofit any previously install BDS 8" long arm system.
