Hi Keith, great question.

Yes, the rail adapter part # C88KR will fit your 2024 Chevy Silverado 2500HD so as long as your truck came with that underbed prep package with the holes in the bed.

This adapter is specifically designed to fit 2020–2026 Silverado 2500/3500 trucks that have the factory puck system (OEM towing prep package), as long as you have that, you are good to go!

One quick thing to be aware of is that this adapter adds about 3-1/2 inches of height to your hitch setup, so you’ll want to keep bed rail clearance in mind depending on your trailer.

If your truck does not have the factory prep package and just has a bare bed, this won’t work, and you’d need a full rail install kit for the Chevy part # C16204 for the rails and part # C16429 for the custom bracket kit.

We do accept returns, although there may be a restocking fee depending on the situation. That said, this is confirmed to fit your truck, so I wouldn’t expect you to run into any issues there. Just out of curiosity, what’s making you question the fit? I’m happy to take a closer look with you.

What fifth wheel hitch are you using?

I have these on my 2024 HD2500 with the factory 5th wheel prep. They work great. Did add a little height to the hitch but the clearance is fine. I use the same hitch that came out of my 2007 2500HD with traditional bed rails.

@AlexC It's always nice to hear from someone using the parts. What kind of fifth wheel do you tow?

Worked perfectly with my 25 silverado 3500hd with 5th wheel prep package. Adds about 2 inches in mounting height.

Kieth, I had a Dodge dually with rails in it and traded it on a 2020 GMC. I didn't want to get a whole new hitch so I got the adapter for my GMC. It woks fine. It is heavy and somewhat cumbersome to put in but it saved quite alot of money not having to buy a new hitch.

Worked great on my F-350 with the OEM puck system. Didn't want to by a different 5th wheel hitch to match up with the entire system already installed on my 5th wheel camping trailer. It's heavy but the tractor doesn't care.

@BradA Hi Brad, I really appreciate you sharing that. That’s exactly why a lot of folks go with this adapter, it lets you keep the hitch you already have instead of starting over, which is a big win. You’re not kidding about the weight either, but sounds like you’ve got the right equipment to handle it without any trouble. What kind of trailer are you pulling with your setup?
