The Hellwig aftermarket front sway bar for the 18K chassis also only has one hole. It wouldn't surprise me if the Roadmaster bar actually comes from the same fabricator. It can't be easy to form this big steel with such limited sales numbers.
There is a clearance issue with the transmission lines that could possibly rub the tip of the Hellwig bar on the right side on the 18k chassis. I zip-tied a short piece of rubber hose on the line to prevent friction damage if they should ever meet during movement.
I installed the Hellwig as was slightly less expensive. Couldn't be happier, really made a huge difference. The upgraded hardware makes the OEM bar look like a toy by comparison. Plus you get new huge poly bushings and synthetic grease.
