Coldwater, MI: BDS adds to its Super Duty lineup with new 4" & 6" radius arm configurations for 2005-2016 F250/F350 Trucks. Available with your choice of BDS Pro-Ride coil springs or upgrade to FOX 2.5 R/R coilovers, these kits offer great ride, stellar performance and predictable handling. These kits utilize a pair of heavy-duty replacement radius arms built to withstand whatever abuse you can throw at them. Constructed from 1-3/4" OD -10GA DOM tubing with support gussets, these radius arms are far superior to the factory-stamped steel units. They use a high clearance design for extra ground clearance and an additional clearance of oversized tires. They incorporate factory-style 3-1/4" rubber bushings to minimize road vibrations and allow for a long, maintenance-free bushing life. The arms bolt into the factory mounting points and utilize a lower cam slot to be used with the provided cam locks to correctly position the front axle and correct caster angle.

Full length Pro-Ride coil springs are a direct replacement for the stock springs to provide lift while maintaining ride quality. If upgrading to coilovers BDS provides upper and lower mounting brackets to allow you to bolt-in the race proven FOX 2.5 Factory Series remote reservoir coilovers with optional DSC (dual speed compression). The stock shock mount is repurposed to install an auxiliary FOX 2.0 performance series gas shock. To improve steering angles a forged drop pitman arm is supplied with an integrated drag link flip. Used in combination with the 1/4" thick heavy-duty track bar drop bracket will position the front axle and keep the track bar angle in phase with the steering for improved handling. Also included for the front suspension is a pair of sway bar relocation brackets, bump stop extensions, brake line relocation brackets, and a steering stabilizer mounting bracket.

In the rear, depending on the year range BDS supplies lift blocks, block + add-a-leaf, and replacement GlideRide leaf springs options to lift and level the stance. The GlideRide leaf springs integrate an overload leaf for great all around capability, load capacity and limit any potential axle wrap. Also included are rear u-bolts, rear brake line relocation brackets, and your choice of rear NX2 gas or FOX 2.0 performance series gas shocks. As with all kits, these include all hardware and step-by-step instructions to complete the installation. As with all BDS lift kits, this kit is backed by Factory Protection Plus for peace of mind wherever your adventures may take you. Factory Protection Plus includes BDS’s exclusive No Fine Print Warranty along with a 5-year, 60,000-mile drivetrain warranty. Take your Super Duty to the next level with BDS Suspension.
