Ride Higher With Confidence And Precision Control

When you're ready to transform your Super Duty into a high-performance machine with attitude, the BDS 4-Inch Lift Kit with FOX 2.5 Performance Elite Shocks delivers the perfect balance of ride quality, capability, and rugged looks. Built specifically for 2017–2019 Ford F250 and F350 diesel trucks, this system gives your truck room for up to 37-inch tires and a commanding stance that stands out on any road or trail. But it's not just about height, this kit brings real improvements in handling and comfort. The 4-link conversion dramatically improves suspension geometry, offering increased strength and better control over axle movement during articulation and hard braking. FOX 2.5 Performance Elite shocks with Dual Speed Compression adjusters allow you to dial in your ride feel for work, play, or everyday cruising. With heavy-duty rear blocks, new coil springs, and a completely bolt-on installation, this kit upgrades your entire suspension system from front to back. It’s a complete package for truck owners who want big capability and smooth control without compromise.

Built To Optimize Suspension Function And Front End Geometry

The BDS 2227FPE 4-Inch Lift Kit is engineered for serious performance gains in 2017 to 2019 Ford F250 and F350 4WD diesel trucks. The foundation of this system is a full 4-link conversion, replacing the factory radius arms with heavy-duty upper and lower control arms mounted to high-strength quarter-inch steel brackets. This setup corrects axle position and maintains consistent caster through full wheel travel, leading to improved drivability and more predictable handling under load or at speed. Up front, dual-rate Pro-Ride coil springs provide diesel-specific ride tuning, while the rear features a 5-inch fabricated block and longer u-bolts to maintain a level stance and eliminate axle wrap. To fine-tune ride dynamics, FOX 2.5 Performance Elite shocks come standard with external reservoirs and Dual Speed Compression adjusters for tailored damping based on terrain, payload, or speed. Steering geometry is corrected with a forged drop pitman arm and track bar bracket, ensuring proper front-end alignment. This system is 100 percent bolt-on and provides not just lift, but a complete rethinking of suspension behavior for serious performance gains on and off the road.
