Coldwater, MI: BDS adds the late model F450 to its lineup with new 2.5" radius arm lift systems for the 2020-2022 Ford F450 Super Duty. Designed to improve the stance, ride quality, and offroad capability, these kits are built on the stout platform of the 2020+ F450 to offer all-around improvements with clearance for up to 35" tires.

Starting off these kits are available with full-length ProRide dual-rate coil springs (coilover conversion option coming soon). 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 lightweight stamped steel units they are replacing. The heavy wall tubular construction improves strength while correcting the 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. The 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 center the front axle with the lift installed. The new track bar is adjustable, built from 1-3/8" solid steel stock with gusseted ends, and features 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 on the other end a heavy-duty ball joint. This setup offers 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 off-road while the sway bar relocation brackets correct sway bar operating angle for optimal performance without sacrificing approach angle. Kits include your choice of NX2 gas or FOX 2.0 Performance Series shocks tuned specifically for this setup.

In the rear, these kits use a 2" lift block and new black e-coated u-bolts to achieve a level to slightly tail high stance while retaining the factory rear springs for ride quality and tow capacity. Take your new Super Duty to the next level with these new 2.5" radius arm systems from BDS Suspension.
