Overview

This 4-inch radius arm lift kit from BDS Suspension is designed for 2014–2018 RAM 2500 gas-powered trucks equipped with factory rear air ride. The kit is engineered to improve stance, performance, and capability, and provides clearance for up to 35-inch tires. Up front, the kit includes gas-specific Pro-Ride coil springs, heavy-duty tubular replacement radius arms, a forged drop pitman arm, a track bar bracket for steering correction, sway bar relocation hardware, and brake line brackets. In the rear, the kit uses heavy-duty air bag spacers, a track bar relocation bracket to correct axle positioning, bump stop extensions, and sway bar links. New air ride leveling sensor brackets are also included to re-position the ride height sensors, allowing the system to perform at factory ride height and maintain full air bag range of motion.
