BDS 4 Inch Lift Kit w/ Radius Arm for 2014-2018 Ram 2500 w/ Rear Air Ride 4WD Diesel

Key Features

• Heavy-duty tubular radius arms improve strength, handling, and caster control, mounting into the factory location with OE-style rubber bushings for smooth, quiet, service-free operation.
• High-strength, progressive-rate, diesel-specific Pro-Ride coil springs deliver the correct lift height and a smooth, predictable ride across varied terrain, built from high-tensile steel to resist premature coil bind.
• Forged drop pitman arm and heavy-duty track bar drop bracket correct front steering geometry and recenter the axle through suspension travel.
• Rear air bag spacers, track bar relocation bracket, bump stop extensions, and sway bar links properly position the rear axle while maintaining full air bag range of motion.
• New air ride leveling sensor brackets reposition the ride height sensors so the system performs just like it does at factory ride height.
• Front sway bar correction, brake line brackets, HD transmission crossmember, and t-case indexing ring correct driveline angles and allow continued use of factory driveshafts.
• Choice of NX2 Nitro Series or FOX 2.0 Performance Series nitrogen-charged shocks front and rear for improved ride quality and off-road performance.
