Rear Wheelhouse Liners

Mac2500HD · August 12, 2011

I know there have been numerous prior threads (here and elsewhere) about GM's OEM rear wheelhouse (wheel well) liners, but I thought it would be best to start this one in order to provide some important information.

In most searches for rear wheel well liners, the results will point to a discussion on part # 19166677. If you search on GMPartsDirect.com you'll also get this number when searching for "wheel well liner" (with the only caveat that it won't fit dually trucks, no mention of not fitting anything above a 1500). In most internet searches there's a good chance you'll end up with this part number as well. #19166677 shows up everywhere.

Unfortunately, part # 19166677 is NOT the correct wheel house liner for a 2500HD truck. There is actually a different part #, 22738993 for the 2500 series trucks (and I believe yet another part number for 3500's). The reason for this is that the 1500 series liner will not clear the 2500's suspension. The 3500 liner also has an additional cut out for the heavy duty bumper mount installed on the outside face of the frame rail on those trucks.

As I said, this has been discussed elsewhere on several occasions, but it doesn't pop up readily in a casual search for the liners so I thought I'd sorta bump it by starting a new thread.

I installed the wheel house liners on my '09 2500HD that I got from GM parts direct .com and they dont look anything like the ones you show in your pictures. They fit very tight I used no fastners and I installed them in about 20 min.

I'll try to find the paperwork and post the part #'s of the ones they sent me Dave

I have read all over the internet that the 19166676 liners are the right ones for the 1500. I have a set in my garage that I wanted to install on my 2011 - 1500, but they are listed as 19166682. I am stumped.....

I just installed these as well, GM# 22738993, and they don't cover the frame either, which was the main reason I bought them. Got a good deal on them though. $93 shipped from a Chevy dealer on ebay.

I didn't know the wheel liners were even available for the 3500. Now I have to go look and see if I can find a set.

Thanks for the tip!

The advantage to the wheel house liner over undercoating is the wheel house liner covers all the openings and gaps keeping the crap out of them.

Thanks for the tip!

They are not available for the Dually.

Tthe wheel house liners on the 2500hd do not cover the frame like they do on the 1500 series trucks

They're not available for the GMT-800 I don't believe.
