GM Locking Gas Cap Part number

[Tanner22]

With gas going the way it is, time to protect the liquid gold in the tank. GM part number is 84308352. Price was 21.00 plus tax.

Great info, does it just go right on or is there more to it?

This is a good idea. HOWEVER ... that part number fits the 2019 Trail Boss ONLY.

... still looking for the correct part for a 2021 ...

edit: So ... apparently just as it is for the Front Receiver ... GM made serious changes for 2021 model year such that parts for earlier models do not fit.

Correct. And the 2021 with the stupid capless flapper valve is one of my design complaints. Since I am in dirt all the time my tank fill space fills up with dirt behind the cover door. When you press the flap with the gas nozzle dirt goes in the tank. I have had to wipe it clean before filling up to avoid this. If anyone finds a solution (locking or not) please let me know.

I'll keep looking ... maybe even Fabricate a low-cost solution (wouldn't be the first time.)

Still not nearly a good enough reason to trade it for a Dodge ...

Ordered mine. $3.83 for the piece of plastic and $9.55 for the shipping. Dont even know where its coming from. Yes, one of those transactions. But hey, I'm off road a lot. I don't like dust going into my gas. Thank you GETGONE. I'm going to give it a try.

Dang! I'm seeing a pair as cheap as $7.95 shipped on ebay. That was about what I paid several months ago.

So 87 octane is what ... more than $6.50 a gallon for you there?

I lived in San Diego in the '80s. Glad to be somewhere else.

$5.85
Costco is cheaper but I wasn’t near one.
SD is still a great place to live but expensive👎

It looks like this is the correct locking gas cap for the 2019-2020 model year.

Got it. As far as a dirt cover goes it fits like it was made for it.

Thanks for the tip!
