BDS Suspension 4" Coilover Conversion 4-Link System

If you're looking for a kit to outperform on the trail and on the street then the BDS coilover conversion 4-link systems is for you. This system uses a pair of precision tuned FOX 2.5 factory series remote reservoir coilovers for superior dampening capabilities and fade free performance when your blazing a trail on the harshest of terrains. While utilizing a pair of specially tuned FOX 2.5 factory series remote reservoir coilovers designed for the weight of the Powerstroke diesel Super Duty, the coilovers come prebuilt for 4" of lift and ready to install right out of the box. They use a smooth bore and honed seamless alloy body, 7/8" hardened steel carbon shaft, Eibach coil springs, 6061-T6 billet aluminum ends and specially formulated race proven oil. The threaded body is easily adjustable to dial in ride height to compensate for accessories like heavy winch bumpers. Also included are heavy duty upper and lower mounting brackets that bolt into the factory coil bucket and lower axle mount for easy installation with no welding required. The upper brackets integrate a mount to secure the remote reservoir. An auxiliary FOX 2.0 gas shocks is used up front to further improve dampening capability.

Upgrading the factory stamped steel radius arms this system converts over to a true 4-link design to improve drivability, performance and strength. The heavy duty 1/4" thick steel frame mounted 4-link brackets bolt into factory holes to allow the four massive tubular control arms to be installed. These arms are build from 2" OD x .250" wall tubing with large greaseable bushings. 4-link design optimizes the front suspension geometry and reduces caster change through wheel travel to less than 1-degree.

Also included up front of this system is 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, this kit lifts and level the stance using your choice of a replacement rear lift block or GlideRide leaf springs. The leaf springs use 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 rear of the 4" coilover conversion 4-link system.

As with all BDS lift kits this performance coilover system is backed by Factory Protection Plus offing BDS's No Fine Print Warranty and 5-year, 60,000-mile drivetrain protection.
