Hey David!

There doesn't actually appear to be a front sway bar available for the 2025 ProMaster chassis on your Thor Tellaro. I looked into the # RM84NQ part you mentioned and this is a pre-order for later models (2026-) of the ProMaster, so it's not going to work on your RV.

If you're looking to upgrade the comfort level of your Tellaro's ride, I highly recommend adding a rear sway bar if you haven't already, which IS available for your ProMaster with the Roadmaster # HE74YR. Typically when trying to improve the suspension, the rear sway bar is actually what we recommend adding first, as it almost always provides the most noticeable change over stock components.

What kinds of issues are you having with travel right now? Have you already added any upgrades? Also please tell me about your adventure plans with the Tellaro this summer...
