BDS 4 Inch Lift Kit | Ford F250/F350 Super Duty (2011-2016) 4WD Diesel | Leaf Springs | NX2 Nitro Series Shocks

This variant uses a Leaf Springs rear lift configuration paired with NX2 Nitro Series shocks. The multi-leaf progressive design provides a smooth ride while maintaining factory payload weight ratings. NX2 Nitro shocks feature a nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, a 1-3/8-inch high-flow piston, dual-welded ends for increased strength, self-lubricating seals, and a silver powder coat finish with vehicle-specific valving for better control.

Overview

This 4-inch lift kit from BDS Suspension is engineered for 2011–2016 Ford F250 and F350 Super Duty diesel-powered trucks. The kit increases ground clearance, improves stance and capability, and provides clearance for up to 35-inch tires. Up front, the kit includes diesel-specific Pro-Ride coil springs, heavy-duty radius arm drop brackets, a forged drop pitman arm, track bar bracket for steering correction, sway bar relocation, and brake line brackets. In the rear, the kit utilizes a high-strength fabricated lift block or leaf spring option, a u-bolt flip kit for maximum ground clearance, and brake line brackets. Precision-tuned shocks are included in both NX2 Nitro and FOX 2.0 Performance Series configurations.
