Buying Guide and FAQs
Buying Guide: Factors to Consider When Choosing Harley Bike Gas Tank Caps
- Compatibility: Ensure the cap fits your Harley's tank type (e.g., pre-82 twist-on, late-model thread-in, Softail low-profile chrome exclusions). Use the vehicle selector for model-specific matches, noting vented/non-vented and locking/tethered restrictions to avoid fit issues.
- Type of Use: For security-focused riding, choose locking caps; custom or aesthetic builds benefit from decorative designs (e.g., skull, Live To Ride); standard use suits vented aero or twist-on for reliable fuel management in street conditions.
- Components and Upgrades: Select caps with ratchet mechanisms for torque alignment or dummy caps for decoration; upgrade to fuel doors/latches for dash accents. Focus on seals (Nytrel/cork) and threads (left/right-hand) for leak-free performance.
- Brand and Quality: Opt for Drag Specialties for versatile vented/locking options, Arlen Ness for ratchet billet designs, Covingtons for CNC machined doors, or PRO-ONE for smooth fuel doors. Prioritize die-cast/billet aluminum or stainless steel for durability and corrosion resistance.
- Installation and Cost: Most caps are twist-on or thread-in for easy DIY setup; fuel doors use existing hardware. Prices range from $26.73 for basic twist-on to $203.95 for premium CNC doors—factor in sales (up to 19% off) and free shipping over $99 for value.
Frequently Asked Questions (FAQs)
- What Harley models do these gas tank caps support? Caps support various models, with specifics like pre-82 for twist-on, late-models for thread-in, and exclusions for OEM locking/tethered or Softail low-profile chrome tanks—use the year/make/model filter for exact compatibility.
- Vented vs. non-vented caps: Which is better? Vented allow pressure release for safety; non-vented suit specific setups—choose based on tank design and riding needs.
- What materials ensure durability? Die-cast aluminum, billet aluminum, ABS plastic, or stainless steel provide strength and corrosion resistance, with finishes like chrome, black, or gloss black for style.
- Do these include installation hardware? Fuel doors mount with existing hardware; caps are direct replacements—contact support for any questions.
- What if a cap doesn't fit my Harley? Verify tank outlet, thread type (left/right-hand), and model exclusions before buying. Our returns policy allows exchanges or refunds if it doesn't match.
- Can I find related air and fuel parts? Yes—explore fuel pumps, carbs, or air cleaners in the Harley air and fuel category to complement your gas tank cap upgrade.
