Alternate Hardware to Install Roadmaster RM-1209-131 Anti-Sway Bar on 2015 Mercedes-Benz Sprinter

Question:

One person who earlier installed the RM-1209-131 to his 2015 Sprinter indicated that the bolts started to pull through the soft flat washers allowing the brackets to move. He suggested replacing all the bracket mounting bolts with grade 8, fine thread, getting rid of the cheap soft flat washers and using the thick square ones instead. Please give your view of this suggestion. Thanks.

I typically do not recommend folks deviate from the manufacturer's installation instructions because all the development, testing and engineering work has been done with a given product installed in a particular manner.

I spoke with my contact in the tech services department at Roadmaster, who told me that they haven't had ANY reports of this occurring. Changing to a grade 8 bolt and using a thicker washer would be fine. He's guessing that in this particular instance the bolts started to pull through the washers because the bolts were over tightened.

If you click the provided link, you can see the installation instructions which include the proper torque rating for the fasteners used in the installation of the anti-sway bar.
