What you get up front

• Pro-Ride Coil Springs — Gas-specific, progressive-rate springs engineered with proper wire diameter to deliver smooth, predictable ride without premature bind.
• HD Tubular Radius Arms — High-strength replacements mounted in factory location with caster adjustment and OE-style rubber bushings for service-free operation.
• Steering Correction Kit — Forged drop pitman arm and heavy-duty track bar drop bracket keep front axle centered and steering in phase through suspension travel.
• Transfer Case Indexing Ring & New Transmission Crossmember — Allows use of factory front driveshaft at this lift height.
• Sway Bar Relocation & Brake Line Brackets — All hardware to integrate the lift seamlessly into your truck's suspension geometry.

Out back

Heavy-duty rear air bag spacers work with your factory air ride, paired with a track bar relocation bracket to re-center the rear axle. Bump stop extensions prevent suspension binding, and relocated sway bar links maintain roll stiffness across the lift height.

Pick your shocks

• BDS NX2 Nitro Series — Nitrogen-charged comfort and control for daily driving and light off-road use. Smooth, responsive feel at a great value.
• FOX 2.0 Performance Series — Dual-rate damping and external adjusters deliver tuned performance for varied terrain. Premium ride and handling across the board.

Important notes

• Rear Air Ride Only: This kit is engineered for Ram 2500 trucks equipped with factory rear air suspension. It will not work on models with traditional coil or leaf springs in the rear.
• Max Tire Size: 35 x 12.5 inches. Larger sizes will contact suspension or body at full articulation.
• OE Wheel Offset: Stock wheels will work; verify backspacing if running aftermarket wheels to avoid rubbing at full turn or bump.
• Transfer Case Indexing: The indexing ring and new crossmember supplied in the kit allow retention of the factory front driveshaft. This modification is critical for proper driveline function at 4 inches of front lift.
