2013-2018 Cummins 4 Link 4" BDS Lift Kit 1 Ton w/air suspension (BDS1644H)

Your airbag-equipped Cummins is a powerhouse that needs a suspension setup to match it. BDS has come out with kits specifically designed for these trucks. Designed to convert the factory radius arm over to a stronger 4-link design offering improved stability, handling, and articulation.

Tire & Wheel Combinations:

  • 37x12.50 w/ 17x9/18x9/20x9 and 5.625"
  • 35x12.50 w/ 17x9/18x9/20x9 and 4.5"

Notes:

  • The carrier bearing drop (122405) is necessary for models equipped with the two-piece rear driveshaft.
  • Some vehicles may require rear driveshaft spacer kit 122007 to maintain adequate rear driveshaft engagement.
  • Will NOT fit cab and chassis models.
  • The shocks used in these kits are different than a standard 3500, do not use a different shock length, or damage to the airbag will result.
  • Can be used on SRW or DRW models.
