Can I buy the mounting hardware and brackets separately? I had some punk raid my garage, and all I have left is the sway bar itself.
( Corey, 11/30/2020 )

Individual components from the kit can be purchased separately. You would purchase these directly from Roadmaster, not us.

Here is a link to the installation instructions which show a picture and corresponding part # for each component on page 2: https://ultrarvproducts.com/PDF/Roadmaster/1139-149-2.pdf

Have 2017 thor Outlaw 37BG Has 26000 lb chassis. Do you carry rear anti sway bar that will fit my unit? ( Val Walker, 06/06/2019 )
The 1139-149 would be the “most” correct rear sway bar for that application, however, we have seen where Thor put additional reinforcement plates on the frame rail that interfere with where the sway bar is designed to attach to the frame. I would print the installation instructions and then crawl underneath the coach to see if it looks like installation would be possible.  ( Support )
2019 Thor outlaw MB any idea if this will work? ( Shaun Clinkinbeard, 05/05/2019 )
We have seen where some Outlaw toy-haulers have additional supports and frame reinforcements which either prevent or make installation difficult. If you look at the installation instructions you can try to determine if yours has room to be installed. ( Support )
Is this the right rear Anti-Sway bar for my RV ( John Hughes, 05/04/2019 )
I checked your VIN and it shows you have a 22,000 GVWR. The correct rear anti-sway bar for your chassis is the 1139-145. ( Support )
