  • Bob Wysolmierski says:

    I guess I am a little confused 4 “ high lift at what setting is that based on??? arrow mode. Normal mode or off road2 mode????

    I hope you can help clarify

    Thank you,

  • Heath Schley says:

    Does it lever the truck or will the truck still have a Factory Rake?

    • Carter @ BDS Suspension says:

      Hey Heath, this kit s designed to level out the stance and eliminate the 1″ factory rake. Front uses a 4″ airbag strut spacer, the rear uses a 3″ airbag spacer.

  • Heath schley says:

    Do y’all have a kit in the works for the 2020 ram rebel with ecodiesel?

    • Carter @ BDS Suspension says:

      Hey Heath, no 2020 kits quite yet. Our 2019 RAM 1500 4WD kits have not been approved for use on the 2020 models and there are some minor revisions that are being addressed. As soon as 2020-compatible kits are on the shelf ready for sale we’ll be sending out announcements and adding them to our website

      • Jacob says:

        Any updates on progress to approve this kit for 2020 models with air suspension? Some of your competitors have kits available now for the 2020. 2021 models are coming soon!

        • Carter @ BDS Suspension says:

          Hey Jacob, similar to my response on your other message while we don’t expect any changes, at this time the 2019 RAM 1500 Air Ride kits haven’t been tested to confirm compatible on the 2020 models. Its on the list of vehicles they plan to bring in soon though. Stay tuned for updates

  • Bryan says:

    Is this kit strictly for 4WD or can it be used on a 2WD RAM 2019 1500?

    • Carter @ BDS Suspension says:

      These kits are designed for 4WD only. The 2WD models use a slightly different suspension configuration

  • Jake says:

    Any updates on when 2020 w/air ride kits will be available? It’s almost 2021!

    • Carter @ BDS Suspension says:

      Hey Jake, sorry for the delays, we’d had some delays with the 2020 Air Ride compatible kits, but expect to have those kits out by the end of this month. Keep an eye out for updates


    Does the 2020 kit work on the 2021 Limited?

    • Courtney @ BDS Suspension says:

      Kits have not been approved for the 2021 models at this time. As soon as we have kits available we will have announcements on our social media pages, blog, and website.

  • Frankie says:

    How long will it take to install this kit ?

  • Roger says:

    What is the time frame to get a kit for the 2021 models?

    • Carter @ BDS Suspension says:

      We have a truck in the ’21 RAM 1500 w/ Air Ride in the shop this week for validation of compatibility with ’20 models, assuming all goes smoothly we’ll have the listings up soon. If modifications are needed it may extend that release date a bit.
