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.
- Not sure about your trim, cab or bed length? Use the vehicle selector at the top of the page, or contact us with your VIN and we will confirm fitment before you order.
