2017-2019 F250 & F350 4WD BDS 4" Radius Arm Lift Kit (NX2 Shocks) BDS-1521H

Heavy-Duty Radius Arm Suspension Lift

Make no mistake - the 2017-2019 Super Duty is a sight to behold straight from the factory. However, throw a 4" lift at it and it becomes an entirely new beast. Not only will the BDS 4" Radius Arm Lift Kit eliminate front rake and lift your ride to an appropriate height, but you'll also be able to squeeze on larger wheels and tires making your Super Duty even more capable and aggressive looking. Featuring vastly improved radius arms constructed from 1-3/4" OD -10GA DOM tubing with support gussets, this is one of the more dependable and well made lift kits on the market. This is the perfect lift kit to help you outfit your truck with a larger wheel/tire combination thanks to the radius arms' high clearance design and inward formation. The arms feature factory style 3-1/4" rubber bushings which help to minimize road vibrations and prolong bushing life. The assembly bolts right into the factory mounting points, positioning the front axle to correct caster angle. Complete with high-quality ProRYDE coil springs, an NX2 series steering stabilizer and your choice of high performance shocks, nothing can stop you from going where you want to go once your '17-'19 F250 or F350 is equipped with this awesome 4" lift kit.

Full-Length ProRYDE Coil Springs and NX2 Series Shock Absorbers

The BDS 4" Radius Arm Lift Kit rides on high end ProRYDE full-length coil springs to deliver a smooth, supple street ride and capable off-road performance. Along with a forged drop pitman arm, BDS includes an integrated drag link flip to maintain proper steering angles. Together with the included 1/4" thick heavy duty track bar drop bracket, the system keeps your track bar angle in phase with steering for improved handling. BDS tops off the 4" Radius Arm Lift Kit with a pair of sway bar relocation brackets, bump stop extensions, brake line relocation brackets and a NX2 series steering stabilizer with mounting bracket. The rear lift is achieved with 5" fabricated blocks with integrated bump stops and e-coated u-bolts. This lift kit comes with your choice of front and rear shocks. This particular kit comes equipped with the BDS NX2 series gas shocks that offer lightning fast dampening that adapts to different terrain for uncompromising on and off-road performance. The 2" bodied shocks use a large 1-3/8" fluon banded piston, self lubricating seals and a 14mm hardened chrome shaft to help resist rock chips and corrosion.
