These kits use full length ProRide coil springs 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. 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 1" bolt-on lift block and new black e-coated u-bolts to level stance while retaining the factory rear springs for ride quality and 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.
