4-Inch Radius Arm Lift Kit w/ NX2 Nitro Shocks

Improve the stance, performance, and capability of your Ford F350 Dually Super Duty diesel truck with this 4-inch radius arm lift kit from BDS Suspension. This kit is engineered to provide clearance for up to 37-inch tires, enhancing your truck's off-road readiness. The installation process is straightforward and 100% bolt-on, designed for ease and efficiency. Up front, the kit features diesel-specific Pro-Ride coil springs for optimal lift and ride quality, complemented by heavy-duty replacement radius arms. These high-strength tubular arms offer caster adjustment for various lift heights and utilize OE-style rubber bushings for smooth operation. For steering correction, a forged drop pitman arm and a heavy-duty track bar drop bracket are included to maintain proper geometry and recenter the front axle. Additional front components include sway bar relocation brackets, brake line brackets, and precision-tuned nitrogen-charged shocks. In the rear, the kit employs high-strength fabricated lift blocks to achieve a level stance, paired with longer u-bolts. Brake line brackets are also provided, along with a choice of NX2 Nitro or FOX Performance shocks. The NX2 Nitro shocks offer a nitrogen-charged, twin-tube design with 10-stage velocity-sensitive valving and dual-welded ends for durability. Alternatively, the FOX 2.0 Performance Series shocks feature a 2-inch impact-extruded aluminum body, an internal floating piston monotube design, and application-specific valving for maximized performance. This lift kit is recommended for use with 37 x 12.5-inch tires on wheels with a 5-inch backspace (17, 18, or 20-inch diameter). Trimming may be required for optimal tire fitment. The kit is compatible with 2020-2022 Ford F-350 Super Duty 4WD DRW diesel models.
