These 6" systems upgrade the factory stamped steel radius arms to a high strength 4-link offering improved handling, stability, strength and caster control during wheel travel. The 4-link brackets are built from 1/4" steel and key off the factory frame bracket and transmission crossmember for extra strength. Full length 6" ProRide diesel specific coil springs are used in the standard 4-link 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. For improved performance BDS offers FOX 2.5 factory series remote reservoir coilovers along with an auxiliary FOX 2.0 performance series IFP shock. 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.
In the rear of these new 6" systems BDS offers your choice of a replacement lift block or upgrade to GlideRide leaf springs that offer a smooth ride and ultilize a large overload leaf for additional load capacity. 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. Take your Super Duty to the next level with BDS Suspension.
