2017-2019 Ford F250-F350 Super Duty 4WD 2.5" Coil-Over Radius Arm Lift Kit - 1543F

Joining the ranks of BDS Suspension's lineup of 1-8" suspension lifts for the 2017-2019 Ford Super Duty trucks are new 2.5" coilover radius arm systems designed to provide a next level performance, strength and capability at a modest lift height with room for 35" tires. In place of the factory coil springs these new 2.5" systems upgrade to a pair of precision tuned FOX 2.5 factory series remote reservoir coilovers. These coilovers offer 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. A set of auxiliary FOX 2.0 IFP performance gas shocks are also supplied to further enhance front performance.

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" systems is a high strength replacement track bar designed to recenter the front axle with the lift installed. This new bar is 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 FOX 2.0 performance series gas shocks to compliment the front performance. Take your new Super Duty to the next level with this 2.5" coilover radius arm system from BDS Suspension.
