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)

  1. 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.
  2. 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.
  3. 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.
  4. Do these include installation hardware? Fuel doors mount with existing hardware; caps are direct replacements—contact support for any questions.
  5. 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.
  6. 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.

Big Power, Nice Sound!

Picked up a Pro Circuit pipe and silencer for my YZ125 it’s a game changer. The power feels way better and the sound is awesome.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
