  • BDS’s exclusive No Fine Print Warranty

Ford Super Duty C/O Lift Kits: BDS Suspension adds to its extensive lineup of coilover suspension systems with new 6” Performance Coilover 4-Link Systems for the 2011-2016 Ford F250/F350 Super Duty  4WD diesel trucks. Designed to allow the installation of Fox 2.5 factory series remote reservoir coilovers, this new system far surpasses the performance and capability of your Super Duty’s stock suspension with more stability, improved handling, and better dampening in any terrain. Michigan built and Moab tested, these new coilover conversion 4-link systems are built to perform.

The system utilizes a pair of Fox 2.5 factory series remote coilovers tuned specifically to optimize suspension performance on the diesel equipped Ford Super Duty. The 8″ travel coilovers feature a smooth bore and honed seamless alloy body, 7/8″ hardened steel carbon shaft, Eibach coil springs and black anodized machined 6061-T6 billet aluminum mounts. The key to mounting these new coilovers are the new mounts supplied by BDS. In place of the factory stamped steel coil buckets BDS includes a pair of the massive 1/4″ thick steel, gusted construction coilover mounting brackets designed to bolt in place using the factory frame holes. This provides a stout mounting point for the new Fox 2.5 coilovers with provisions to mount the remote reservoirs as well as an auxiliary shock for even further dampen capability. The auxiliary shock mount will accept anything from the supplied Fox 2.0 Performance series shocks up to the massive 3.0 Fox Factory series cylinders. At the axle, new double-shear C/O mounting brackets bolt in for a direct replacement to the factory coil seats.  The all brackets are finished in a durable textured black powder coat finish with integrated mounting tabs to retain the factory brake and ABS lines. 

To complement the increased performance of the new coilovers, BDS designed the kit around the popular BDS 4-link conversion to upgrade the stock stamped steel factory radius arms.  The BDS Super Duty 4-Link conversion has long been a go to for 2005-15 Super Duty truck owners looking to improve their trucks drivability and performance.  The full replacement 4-link frame brackets bolt into factory holes and create a solid mounting location for the massive tubular 4-link arms.  These arms allow the front suspension geometry to be optimized for control and handling through all types of terrain. The front portion of the lift system also includes a forged drop pitman arm and front track bar relocation bracket to correct steering and track bar angles as well as to center the axle under the vehicle.  Front bump stop extensions, sway bar drops, and brake line relocation brackets round out the front of this system.  In the rear, full replacement BDS Glideride leaf springs provide the lift needed to level and level the stance. The springs are a 5-leaf design with built in overload leaf to assist when carrying heavy loads. New black e-coated u-bolts, brake line brackets and Fox 2.0 performance gas shocks are supplied to round out the 6″ coilover conversion 4-link system.
