4" 2017-2019 Ford F250/F350 4WD Radius Arm Lift Kit by BDS Suspension

The BDS Suspension BDS1520FS / BDS1520H is a great way to lift your Ford F250 / F350 4wd truck to allow up to 37-inch diameter tires. These replacement arms are far superior to the factory-stamped steel units, built around heavy-duty radius arms that use 1-3/4" OD -10GA DOM tubing with support gussets. Featuring a high clearance design for extra ground clearance and is formed inward to allow for additional clearance of oversized tires. The arms correct the caster angle by bolting into the factory mounting points and repositioning the front axle.

BDS Pro-Ride front coil springs lift the front end 4 inches while maintaining performance and ride quality. A forged drop pitman arm corrects steering angles, along with a supplied integrated drag link flip. The front axle remains centered with the use of a 1/4" thick heavy-duty track bar drop bracket. Also included for the front suspension are a pair of sway bar relocation brackets, bump stop extensions, brake line relocation brackets, and an NX2 series steering stabilizer with mounting bracket.

In the rear, the factory blocks are replaced by a pair lift blocks that feature integrated bump-stop wings and e-coated extended U-bolts.

To improve ride quality and performance, you can choose BDS NX2 Niro Gas (2-inch steel body), Fox 2.0 Performance Series IFP gas shocks (2-inch aluminum body), or 2.5 Performance Elite remote reservoir adjustable shocks (2.5-inch aluminum body). Performance Elite shocks feature an aluminum 2.5-inch body and DSC adjusters to fine-tune from a soft to firm ride.
