What you get up front

• Upper and lower control arms — engineered to maintain proper caster and prevent bump steer across the full stroke.
• Front coil springs — rated for the 5.5-inch lift and integrated load capacity of a Ram 3500 dually or single-rear-wheel.
• Front strut assemblies — matched to the spring rate and designed to work seamlessly with the 4-link geometry.
• Bilstein or FOX shocks — your choice of tier, front and rear.
• Bump stops and hardware — all brackets, fasteners, and protective components included.

Out back

The rear air suspension is retained and reindexed — no springs to swap. Four-link rear geometry corrects for the lift height and maintains factory ride height sensor calibration. Rear shocks match your chosen front tier for consistent damping across all terrain.

Pick your shocks

• BDS NX2 Nitro Series — comfortable daily driver with good bump compliance and predictable on-road manners.
• FOX 2.0 Performance Series — premium adjustable damping, sharper off-road response, and more trail tuning control.

Important notes

• Rear air suspension must be functional before installation; the kit reindexes but does not replace the air springs or compressor.
• Factory driveshaft angles are preserved — no carrier bearing or driveshaft modifications required.
• OE wheel offsets are compatible; confirm your wheel backspacing does not exceed factory limits (typically 3.5–4.5 inches for dually models).
• ABS and airbag sensors require no recalibration after installation.
• Installation timeline is typically one day for shops familiar with the platform; BDS provides detailed setup guides for proper transfer case re-indexing.
