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

This variant uses a Block Kit rear lift configuration paired with NX2 Nitro Series shocks. The cast iron lift blocks are tapered for correct pinion angle, with an offset steel pin to restore axle position and reduce axle wrap. 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.
