BDS 4-Inch Suspension Lift Kit with 4-Link Conversion

The BDS Suspension BDS1577FS is a comprehensive 4-inch suspension lift kit engineered to enhance the stance, performance, and capability of 2017-2019 Ford F350 Dually "DRW" Super Duty trucks equipped with diesel engines. This kit facilitates the installation of up to 37-inch tires, offering a significant upgrade for off-road and on-road driving. This system converts the factory radius arms to a BDS 4-link setup, optimizing suspension geometry for improved handling and stability. It utilizes heavy-duty, 1/4-inch steel brackets for mounting control arms and correcting axle positioning. For steering correction, the kit includes a forged drop pitman arm and a heavy-duty track bar drop bracket to maintain proper alignment throughout suspension travel. In the rear, the lift is provided by a high-strength fabricated block and longer u-bolts. The kit comes complete with precision-tuned nitrogen-charged shocks, offering a choice between NX2 Nitro or FOX Performance options. Installation is described as difficult and estimated to take 10 hours, requiring specialized tools such as a torque wrench capable of 405 ft-lbs, a drill, and a pitman arm puller/reciprocating saw. Notes for installation include that minor trimming may be necessary for clearance of 37x12.50 tires on certain wheel setups.
