BDS raises the bar with 6" radius arm systems for the Ford Super Duty.

These 6" systems upgrade the factory stamped steel radius arms to high strength tubular radius arms allowing for caster control and superior strength. Full length 6" ProRide diesel or gas specific coil springs are used for the additional ride height paired with your choice of BDS NX2 series gas shocks or FOX 2.0 IFP performance gas shocks for a smooth ride on any terrain. A forged drop pitman arm and heavy duty track bar relocation bracket are supplied to correct steering angles and recenter the front axle. Also supplied for the front are bump stop extensions to limit suspension compression, sway bar drop brackets to correct the sway bar positioning, and brake line relocation brackets. At 6" of lift driveline adjustments are necessary so a precision built transfer case indexing ring is supplied to improve front driveline operating angle.

Additionally a high clearance transmission crossmember is supplied. In the rear of these 6" lift systems are replacement rear lift blocks to level out the stance. Additionally high strength black e-coated u-bolts are supplied along with a pair of matching NX2 or FOX 2.0 gas shocks to compliment the front setup for all around impressive performance.
