Overview

This 2.5-inch radius arm lift kit from BDS Suspension is designed for 2011–2016 Ford F250 and F350 Super Duty diesel-powered 4WD trucks.

Up front, the kit includes diesel-specific Pro-Ride coil springs, heavy-duty tubular replacement radius arms, a high-strength 1-3/8-inch solid steel adjustable track bar for steering correction, brake line brackets, and precision-tuned nitrogen-charged shocks. In the rear, the kit utilizes a high-strength fabricated lift block (configuration-dependent), longer U-bolts, and a matched set of shocks.
