Question:

I need a hitch expander from 2 inch to 2 1/2 inch. I cant seem to find one on your website. I have a 2 inch hitch and need to adapt up to 2 1/2 for a set of rock tamers that are 2 1/2 inch.

Hey Randall, welcome back! I've got a way easier solution for your Rock Tamers but the reason you can't find an adapter is because that don't exist. I've never seen a 2" to 2-1/2" adapter. They go smaller but not bigger.

I recommend using the Replacement Hub for Rock Tamers Heavy-Duty, Adjustable Mud Flap System for 2" Hitches item # ERT034. This is the one that comes on the 2" hitch Rock Tamers. It's got the same fitting sizes as the ones that come on the 2-1/2" models like item # RT47VR or item # ERT00110.

The Replacement Hub item # ERT034 will allow you to use your 2-1/2" Rock Tamers on your 2" hitch and ball mount.

Did you get a new truck recently and what kind of trailer are you towing?
