Why are rubber mounts so important for a gas tank?

Motorcycles produce significant vibration, which can be transferred directly to the gas tank through a solid mount. Rubber mounts act as dampers, absorbing these vibrations to prevent cracks from forming at the mounting tabs and seams over the long term.

Can I install a custom chopper tank on my Sportster without modifying the frame?

Yes. Our Lowbrow Customs Gas Tank Adapter Brackets are specifically designed to let you bolt a wide range of custom tanks onto 1982-2003 Harley-Davidson Sportster frames using the stock mounting locations.

What is typically included in a gas tank mounting kit?

A complete motorcycle gas tank mounting kit, like those from Colony, usually includes all the necessary components for one motorcycle: the correct shouldered bolts, grommets, washers, nuts, and spacers required for a factory-style installation.
