2023 Ram 3500 fitment tips
- The 3500 uses rear leaf springs, unlike the coil-spring 2500 - pick 3500-specific lift and leveling kits.
- Dually trucks need DRW-specific fender flares, running boards and mud flaps.
- Long-bed trucks are popular with in-bed transfer tanks and toolboxes - confirm 8 ft vs. 6 ft 4 in.
- Trucks with rear air suspension need air-compatible leveling kits.
