Important Notes

  • Extreme care/caution must be taken to follow the steps of these instructions to prevent any air leaks or damage to the bags during installation.
  • The factory air ride is a closed loop system. Opening the system more times than recommended in the lift instructions will require the system to be recharged (this can be done at any RAM dealer service department). A scan tool is needed to access the air control module to perform the service.
  • Frame bracket modification is required.
  • Fits 4WD models equipped with factory air ride only.
  • Stock 17-18" wheels cannot be reinstalled, stock 20"+ wheels can be reinstalled with factory size tires.
  • Trucks equipped with factory 22" wheels must use the large bore steering knuckles.

  • Christian Howell says:

    When will the 2021 ram 1500 4″ lift kit be available for the air ride equipped trucks.

    • Carter @ BDS Suspension says:

      At this point these kits are pending fitment validation to confirm compatibility with the 2020 RAM 1500 4WD Air Ride applications, We hope to have this completed very soon.

  • Greg Soulis says:

    How much without installation?

  • Ricardo says:

    Do you make a lift kit for a 2wd with air ride

  • Daniel Yoo says:

    Do you make a lift kit for the ram rebel air ride eco diesel

    • Carter @ BDS Suspension says:

      Hey Daniel, officially we don’t recommend use of this kit on the EcoDiesel equipped RAM 1500/Rebel models due to front driveline issues.

  • Casey says:

    Does this kit level the front and rear? Additionally, I have a ‘21 limited with air ride, am I able to use this kit or do I have to wait until it’s approved for the ‘21?

    • Carter @ BDS Suspension says:

      Hey Casey, the kits are designed to lift+level the stance, 4″ in the front and 3″ in the rear while retaining full functionality of the adjustable ride height modes. We haven’t released the 2021 compatible kits quite yet, but should have them out later this month. There are some minor tweaks from the 2019-2020 to 2021 with the suspension that are being addressed. Keep your eye out for an upcoming announcement once available

  • Shane Barry says:

    Do you make these kits for the 14 ram 4×4


    I have 2021 ram Rebel with air suspension and would like to purchase the 4” lift.
    Does the 2020 fits on the 2021 ram rebel or is there a specific 2021 kit ?

    • Carter @ BDS Suspension says:

      While they are very similar, there are some minor differences on the 2021 models. We’ll have the 2021-compatible kits out in the coming weeks

  • Mike says:

    Can this kit be put on a 2016 1500 4×4?


    How much longer do we have to wait for the 2021 kit ?
    Every comments I read you responded, in a few weeks.

    • Carter @ BDS Suspension says:

      We’re expecting them in any day now, unfortunately supplier lead times have been more up in the air lately to get some of the components we outsource. As soon as kits are available we’ll be adding them to our website and will send out an announcement

  • Andrew Webb says:

    Any chance you guys are working on a kit for the 2021 factory air ride equipped 4×4 yukon/tahoe? Specifically the AT4/Z71 models.

    • Carter @ BDS Suspension says:

      Not at this point, however late model Tahoe/Yukon is on our list of future kit development. No timeline yet

  • Robbie says:

    Cater, Any response to Stephane’s question?

  • Brian Stikeleather says:

    2021 Dodge Ram limited with air ride out yet? I see the almost in the past comments. If so I would like to order.

  • Raul says:

    Any update yet on 4″lift kit for 2021 1500 limited

  • Christopher Phalan says:

    Might as well start working on the 2022 Limited Air Ride lift kit, is that in the plans? Thanks!

  • David Robin says:

    I have a Ram 2019 – 1500 Sport with Air-Ride, from what i gather BDS does make a 4″ lift that is compatible with my truck per (
    My question is: Does BDS make a 5″ or 6″ lift that is compatible with this year/model of Ram?

    • Carter @ BDS Suspension says:

      Hey David,
      short answer, no, we don’t offer a lift option taller than the 4″ kit. Reason being we design our kits for compatibility with 4-6″ of lift under the new RAMs. At 4″ of lift the suspension-steering geometry is is very similar to stock allowing for the AirRide ride height adjustability offered in the various ride height modes. In the taller ride modes the stance is similar to a 6″ lift

  • Derek says:

    Can I use the 4 inch kit with stock limited 22×9 rims? If not, can I get wheel spacers to allow to clear this. I see Revel performance offers 2.5 level plus day star spacers and can clear 35 inch tire. I would think a 4 inch lift would clear but hear discrepancies.

    • Carter @ BDS Suspension says:

      Hey Derek,
      The 4″ Air-Ride Kit can be used with the factory 22s, however due to the backspacing of the wheel will require a wheel spacer to install larger (35×12.50) tires due to the larger aftermarket steering knuckles. The factory 22×9 backspacing should be right around 5.75″ backspacing so using a 0.75″ wheel spacer will be needed to achieve our recommended 5″ backspacing measurement.

      Also worth mentioning if your RAM is factory equipped with 22s then you’ll need to order the larger bore knuckle variant that we offer. If you truck is not equipped with stock 22s, you jsut want to swap over to a set order the standard bore knuckles.

  • Matt says:

    Does the price include install with the dealer you pick? Or is it 3k for a 4 inch lift.

    • Carter @ BDS Suspension says:

      Hey Matt, our kit price is for our parts only, install labor and alignment will be charged separately if you have a shop install the parts for you.

  • Joseph Reichard says:

    Any news on the 2022 Ram EcoDiesel limited 4×4 lift kits yet. I only want to put 35” tires on it came with factory 20” rims any idea if any backspacing is required for the rims to fit 35’s
