Coldwater, MI: BDS Suspension is now offering 2.5" radius arm lift systems for the 2020 Ford Super Duty. Available with full length ProRide coil springs or FOX 2.5 factory series remote reservoir coilovers, these 2.5" radius arm systems are designed to improve the stance of your Super Duty while taking performance, capability and ride quality to the next level with clearance for 35" tires. The coilovers option offers vastly superior damping capability to soak up the harshest terrains offroad while offering comfort for your daily commute. They feature a smooth bore and honed seamless alloy body, 7/8" hardened stainless steel shaft, black anodized machined 6061-T6 billet aluminum mounts and remote reservoir and come fully assembled with FOX coil springs. These coilovers are pretuned for optimal performance and preset for 2.5" of lift right out of the box with the weight of the 6.7L Powerstroke diesel engine. They install easily using the supplied bolt-on frame and axle mounting brackets.

In place of the factory stamped steel arms this kit upgrades to heavy duty BDS radius arms. These brawny arms are built from 1-3/4" OD heavy wall tubing, fully welded with gussets for superior strength to the factory units light weight stamped steel units they are replacing. The heavy wall tubular construction improves strength while correcting caster with a lower cam slot. At the frame mount a large OE-style rubber bushing is used to better isolate of NHVs and allow for quiet operation without any need for maintenance. These bushings offer superior durability and quieter operation than arms with heims and flex joints. Also upgraded as part of these new 2.5" lift systems is a high strength replacement track bar designed to recenter the front axle with the lift installed. This new track bar is adjustable, built from 1-3/8" solid steel stock with gusseted ends and a fine thread center turnbuckle with pinch bolts. The track bar comes pre-assembled and ready to bolt into the factory location to adjust to length. At one end these use a greaseable, high-durometer polyurethane bushing and the other end a heavy duty ball joint. This setup offer strength, comfort and quiet operation over track bars that use heims. Rounding out the front of these kits are front brake line relocation brackets to allow enough slack in the lines to cycle the suspension offroad while the sway bar relocation brackets to correct sway bar operating angle for optimal performance without sacrificing approach angle.

In the rear, these kits use a slightly taller 4" replacement lift block and new black e-coated u-bolts to net a level stance without the need to stack blocks to do it. The block integrates a bump stop wing to correctly limit suspension up travel and allow you to retain the factory rear springs to maintain tow capacity. Finishing out the rear are a pair of NX2 or FOX 2.0 performance series gas shocks to compliment the front performance. Take your new Super Duty to the next level these new 2.5" radius arm systems from BDS Suspension.

    Hi, I have a new 2020 F350 Super Duty arriving soon and I’m looking at your BDS Kit 2.5″ 549F. My question – I plan on putting 37″x12.5″ tire w/ 20″X 9″ wheel.
    Is that possible with this kit? If not what do you suggest. This vehicle will be used This vehicle will be used 70% on road/Towing 8K boat and 30% flat dirt trails.

    Thank you

      Hey Anthony, our tire/wheel recommendations are just that, recommendations, based on the specs we’ve tested and confirmed to fit. While we’ve heard customers squeezing 37s on with just the 2.5″ lift, ultimately it will likely require some trimming to clear in all driving conditions (on and off-road use). The other factor will be the backspacing of the wheels used, a larger backspacing of measurement around 5″ will help limit the amount of trimming needed once installed.
