Built To Handle The Load And Control The Ride

This BDS 4-inch lift kit is engineered with both strength and precision in mind, starting with gasoline-specific Pro-Ride coil springs up front that deliver controlled suspension movement across a variety of driving conditions. At the core of the kit are heavy-duty tubular steel radius arms that correct caster angle while maximizing ground clearance, all while mounting directly to factory points with durable OE-style rubber bushings for quiet, maintenance-free operation. Steering geometry is corrected using a forged drop pitman arm and a track bar relocation bracket, keeping everything in sync during wheel travel and helping recenter the axle for more predictable handling. In the rear, progressive multi-leaf springs paired with longer u-bolts help eliminate axle wrap and maintain factory load ratings, while also providing a smoother ride. The FOX 2.5 Performance Elite shocks come equipped with external reservoirs and dual speed compression adjusters to dial in suspension feel based on how and where you drive. Everything in this kit bolts on cleanly and is built for serious long-term use. Whether you’re lifting for clearance, capability, or control, this system has the components to do it right.
