What you get up front

• Pro-Ride coil springs — full-length, gas-specific progressive rate springs engineered with high-tensile steel and properly sized wire to deliver the 4-inch lift without premature coil bind.
• HD radius arms — high-strength tubular arms that replace factory stamped steel, mount in the factory location, and include caster adjustment for geometry correction across the lift height range.
• Drop pitman arm & track bar bracket — forged pitman arm and heavy-duty track bar drop bracket work in tandem to recenter the front axle and minimize steering angle.
• Sway bar relocation, brake line brackets — all ancillaries repositioned to suit the new ride height.

Out back

Heavy-duty air bag spacers lift the rear 2.5 inches, paired with a track bar relocation bracket that keeps the axle centered through suspension travel. New air ride leveling sensor brackets reposition your factory ride-height sensors so the air suspension performs just like stock and maintains full range of motion. Bump stop extensions, sway bar links, and a matching set of shocks round out the package.

Pick your shocks

• BDS NX2 Nitro Series — nitrogen-charged shocks tuned for smooth, predictable ride across terrain with the lift geometry already dialed in.
• FOX 2.0 Performance Series — premium damping for drivers who want sharper response and higher-speed capability without sacrificing daily-driver comfort.

Important notes

• Maximum tire size is 35 x 12.5 — larger tires may rub or cause clearance issues.
• This kit is engineered for 2014–2018 Ram 2500 gas engines with factory rear air ride suspension. It is not compatible with mechanical rear springs or diesel models.
• Air ride leveling sensor brackets are supplied and must be installed to allow the factory air suspension to function at the new ride height.
