What you get up front

• BDS Coilover Conversion with FOX 2.5 Performance Elite — replaces factory coils with a fully tuned FOX coilover setup for independent control, better ride quality, and precision damping on trail and tarmac alike.
• BDS Heavy-Duty Radius Arms — engineered for maximum articulation and durability, keeping geometry stable through extreme articulation.

Out back

FOX Performance Elite rear shocks work in tandem with a 1.25" coil spacer lift to maintain driveline geometry while keeping the truck planted and responsive over rough terrain.

Pick your bump stops

• Rubber Bump Stop — traditional elastomer design, proven durability, solid impact absorption at a straightforward price point.
• FOX 2.0 Hydro Bump Stop — hydraulic technology that soaks up hard landings and extreme compression events, adding an extra layer of control when you're hitting big or pushing the limits.

Important notes

• Fits 2014–2018 and 2025–2026 Ram 2500 4WD diesel trucks only.
• Maximum tire size: 35 x 12.5. Verify backspacing and offset with your wheel choice to avoid rubbing.
• Driveline geometry is preserved via radius arms and coil spacer design — no transfer case re-indexing needed.
• Factory options and trim packages (air suspension, RamBox, etc.) may have compatibility limits — confirm before ordering.
