4" Lift Kit with 4-Link Conversion

The BDS Suspension 4-inch 4-link conversion lift kit is engineered to enhance the performance and capability of your 2017-2019 Ford F-250/F-350 Super Duty 4WD Diesel. This system is constructed with robust 1/4" steel 4-link brackets that integrate with the factory frame and transmission crossmember for superior strength and stability. It features 4" ProRide coil springs for increased ride height and improved on- and off-road comfort. You can choose between BDS NX2 series gas shocks or premium FOX 2.0 IFP performance gas shocks to complement the setup. The kit includes a forged drop pitman arm and a heavy-duty track bar relocation bracket to ensure correct steering geometry and proper axle centering. Additionally, bump stop extensions, sway bar drop brackets, and brake line relocation brackets are provided for the front suspension. In the rear, the kit offers options to accommodate both OE 2-leaf and 3-leaf main spring packs, aiming for a level stance. For trucks with the 3-leaf pack, a 5" replacement block and U-bolt kit is available, featuring high-strength, fully boxed steel blocks with an integrated bump stop wing, finished in a durable black e-coat. Complementary rear shocks (NX2 or FOX 2.0) match the front for balanced performance. This BDS lift kit allows for the fitment of up to 37" tires, and tire and wheel combinations such as 37x12.50 with 17-20 inch wheels with 4.5-5 inch backspacing are recommended. Minor trimming may be required for larger tire fitment. Important notes include the requirement to remove the factory leaf spring block, potential front exhaust modification for gas models, and the possible need for a Carrier Bearing Drop Kit if equipped with a 2-piece rear driveshaft. Installation difficulty is rated at 4 out of 5, with an estimated time of 8-10 hours.
