BDS 4 Inch Lift Kit w/ Radius Arm for 2013-2018 Ram 3500 w/ Rear Air Ride 4WD Diesel

Key Features

• Pro-Ride Coil Springs: Full-length, diesel-specific, progressive rate front coil springs deliver the correct lift height and a smooth, predictable ride across varied terrain.
• HD Tubular Radius Arms: High-strength tubular arms replace the factory stamped steel units, mounting in the factory location with caster adjustment for a wide range of lift heights. OE-style rubber frame bushings keep operation smooth, quiet, and service-free.
• Steering Correction: A forged drop pitman arm minimizes steering angle, paired with a heavy duty track bar drop bracket to keep components in phase through suspension travel while recentering the front axle.
• Front Track Bar Relocation Bracket: Repositions the axle for corrected geometry after the lift.
• Tuned Shocks: Choose BDS NX2 gas or FOX 2.0 performance series IFP gas shocks for improved ride quality and off-road performance.
• Complete Rear Setup: Fabricated lift block, heavy duty air bag spacer, and longer u-bolts work with the factory rear air ride system.
