Polaris Slingshot Billet Aluminum Gas Cap *Requires you to transfer over the Rubber O-ring from your factory gas cap to your aluminum gas cap prior to installation*
Replacing the factory plastic Gas Cap is one of the first mods most Polaris Slingshot owners do. It's a great and cost effective way to immediately set your Slingshot apart from the pack by adding a subtle pop of color to the rear deck lid. These billet aluminum gas caps are a direct replacement to your factory plastic gas cap and install in seconds, but do require you to transfer the rubber O-ring from you factory gas cap over to this billet aluminum gas cap prior to installation. These fuel caps are available in most OE colors to match your Slingshot paint colors. We've opted to powder coat these gas caps vs. the cheaper anodized alternative, as anodizing changes colors and fades with the suns UV rays in a relatively short period time, whereas powder coating maintains its brilliant color for years on end.

It did not come with gasket.I had to buy a factory stock cap to get the gasket out of it.

SlingMods Response:
We appreciate you taking the time to share your experience. This particular manufacturer does not include a new gasket with the aluminum gas cap; it’s designed to reuse the rubber O-ring from your factory gas cap. We have this information highlighted on the product page to help prevent surprises during installation. Apologies for any confusion on this.

The gas cap I bought is perfect. It matches my Slingshot and was so easy to install. It really sets it off. Thanks so much for another quality product.

Gas Cap
Just received my Billet Aluminum Gas Cap and installed on my 2023 Singshot SL. Even tho my Slingshot is Colbalt Blue and the cap is Blue Fire it looks nice and kind of pops. I like!

Replacement Cap
I lost my gas top and order this one for replacement but it didn't come with the gasket for the inside. That's my only complaint
