Built for Ram 3500 gas owners who want 35-inch tire clearance with geometry-corrected suspension. This 4-inch lift kit delivers 4 inches up front and 3 inches in the rear — plus a 4-Link conversion that optimizes axle positioning and minimizes caster change so your truck handles like it was engineered to ride lifted. Works only on trucks equipped with the factory rear air ride option.

Installed and serviced at Road Runner Wheels & Tires. Most kits go in the same day. Call (678) 400-6467 to schedule.

What you get up front

  • Pro-Ride Coil Springs — Gas-specific progressive-rate springs engineered for your truck's weight and tuned to deliver smooth, predictable ride across pavement and rough terrain.
  • 4-Link Control Arms with Conversion Mounts — High-strength 1/4-inch steel brackets replace the factory stamped radius arms, allowing proper upper and lower control arm geometry to correct axle positioning and limit caster change throughout wheel travel.
  • Forged Drop Pitman Arm & Track Bar Bracket — Steering geometry correction that minimizes steering angle and keeps the front axle centered through suspension travel.
  • Bump Stops & Brake Line Brackets — All mounting hardware and protective components included.

Out back

Heavy-duty fabricated lift block, high-strength air bag spacer, and longer u-bolts work together to raise the rear 3 inches while maintaining driveline geometry and load-carrying capacity.

Pick your shocks

  • BDS NX2 Nitro Series — Nitrogen-charged comfort and control for daily driving and light off-road use.
  • FOX 2.0 Performance Series — Premium external-reservoir shocks tuned for responsive handling and durability on aggressive terrain.

Important notes

  • This kit is designed for 2013–2018 RAM 3500 gas trucks equipped with factory rear air ride suspension. It will not fit trucks without this option.
  • Maximum tire size: 35 x 12.5 inches.

Read before installation
6.4L gas models will require exhaust modification to clear the front driveshaft. 5.7L gas models may require exhaust modification as well. The vehicle can be driven without the front driveshaft to an exhaust shop for modifications to be made before reinstalling the driveshaft. The carrier bearing drop is necessary for models equipped with two piece rear drive shaft. Some vehicles may require rear driveshaft spacer kit 122007 to maintain adequate rear driveshaft engagement.
