Gas Caps

Gas Caps for Harley Models

Customize your Harley Davidson’s fuel system with high-quality Harley gas caps designed to replace OEM fuel covers, improve sealing performance, and add custom style to your ride. Gas caps are a small but highly visible component that serve a critical role in keeping fuel secure, preventing vapor loss, and protecting your tank from dirt and moisture. Choose from vented ratcheting caps, billet aluminum designs, and locking fuel cap options that balance functional performance with striking aesthetics.

Vented and Ratcheting Gas Caps for Everyday Use

Aftermarket vented gas caps provide reliable sealing while allowing proper fuel tank venting to support consistent fuel flow and engine performance. Options like the Boosted Brad DMR Gas Cap deliver a classic cast aluminum design with a ratcheting mechanism that allows you to tighten the cap and align the design to match your tank. These types of caps are ideal for riders who want a secure, durable upgrade to the stock cap with improved grip and usability while wearing gloves.

Custom and Machined Aluminum Gas Cap Options

For riders seeking distinctive visual impact, precision-machined gas caps in billet aluminum provide both rugged strength and refined good looks. Options such as the Arlen Ness Gas Caps offer a custom-styled, knurled band for easy handling and enhanced tank aesthetics. These aluminum caps not only stand up to daily riding conditions but also complement custom paint and tank finishes.

Locking and Security-Focused Fuel Caps

Secure locking gas caps give you peace of mind when parking in public or during long trips. Premium locking screw-in caps combine functional fuel sealing with key-lock security to help prevent theft or tampering. These caps are engineered to fit standard Harley threaded tanks while providing added protection without sacrificing style or convenience.

Fitment and Compatibility

Most Harley gas caps in this category are designed for threaded filler necks found on a wide range of Harley Davidson models, including Touring, M8 Softail, Dyna and Sportster machines. Be sure to select the correct cap style and thread fit for your specific tank type to ensure proper sealing and performance. Proper venting and secure installation help maintain optimal fuel delivery and reduce the risk of vapor leaks.
