BDS 4 Inch Lift Kit w/ 4-Link for 2014-2018 Ram 2500 w/ Rear Air Ride 4WD Gas

Key Features

• 4-Link Conversion: Replaces the factory stamped steel radius arms with heavy-duty 1/4-inch steel brackets and HD upper and lower control arms to optimize suspension geometry, improve handling, and limit caster change throughout wheel travel.
• Gas-Specific Pro-Ride Coil Springs: Full-length, progressive rate coils built from high tensile steel deliver correct lift height and a smooth, predictable ride across mixed terrain without premature coil bind.
• Steering Correction: Forged drop pitman arm paired with a heavy-duty track bar drop bracket keeps steering geometry in phase through suspension travel and recenters the front axle.
• Rear Air Ride Preservation: Heavy-duty air bag spacers, track bar relocation bracket, bump stop extensions, sway bar links, and new ride height sensor brackets maintain full air bag range of motion and factory-like leveling performance.
• Driveline Correction: HD transmission crossmember and transfer case indexing ring correct front driveline angles and allow continued use of the factory driveshafts.
• Shock Options: Choose between BDS NX2 Nitro Series (nitrogen-charged twin-tube, 10-stage velocity-sensitive valving, 1-3/8-inch high-flow piston, silver powder coat) or FOX 2.0 Performance Series (2-inch extruded aluminum IFP monotube, CNC-machined 6061-T6 aluminum ends, 5/8-inch hard chrome plated alloy steel shaft, clear anodized finish).
• Complete Kit: Includes bump stops, brake line brackets, and front sway bar correction so everything needed for a proper install is in the box.
