Anti-Rattle for 2015 Ram 3500 With 2-1/2" Receiver Using 2" Reducer

Published 11/11/2026

Question:

I have a 2015 RAM 3500 with 2-1/2” receiver reduced with adapter to hold a 2” shank. What is the best anti-rattle accessory to cut down on the up and down play? I tried the 2-1/2” Roadmaster anti-rattle accessory but the safety chain rings and bumper did not allow enough room to attach it.

Hey Brian! For your 2015 Ram 3500, I recommend our etrailer Anti-Rattle Hitch Collar # e55YV. This is designed for your 2-1/2" receiver and includes a reducer sleeve for your 2" shank, so you can replace your existing adapter and eliminate the movement between the components.

I don't know what you're towing, but this collar does have a maximum towing capacity of 10,000 lbs and isn't compatible with weight distribution setups. You may also notice that we list a restriction for Ram trucks. However, that only applies to fifth-generation models, so it won't be an issue with your 2015 Ram 3500.

What are you towing with your Ram?

Hi Robin… I will check that Hitch Collar out. I’m towing a Sundance travel trailer with a GVW of 9500 with no weight distribution. As an alternative, would you also recommend eliminating the reducing adapter and get a new hitch insert with a 2-1/2” shank? Would that be less movement and rattle?

@BrianH yes, switching to a ball mount with a 2-1/2" shank would eliminate the movement caused by the reducer sleeve. Combine that with the # e55YV and you'll have a really solid setup.

Thank you again Robin… that Hitch Collar is exactly what I need. Just wanted to confirm this will work on my 2015 RAM 3500 and that I don’t have a 5th generation RAM. (I have no idea what generation of RAM that I have)

@BrianH yes, your 2015 Ram 3500 is a 4th-generation model, so the 5th-generation restriction doesn't apply to your truck. You're all set with the # e55YV!
