V-Twin Mfg. 5.1 Gallon Bobbed Tank For Harley FXDF/C / FXDWG 2004-2017

The Ultimate Touring Upgrade for the Modern Dyna: V-Twin Mfg. 5.1 Gallon Tank

The Harley-Davidson Dyna is known for its raw power and nimble handling, but for those who ride the FXDWG Wide Glide, FXDF Fat Bob, or FXDC Super Glide Custom, the stock fuel capacity can often cut the adventure short. The V-Twin Mfg. 5.1 Gallon Bobbed Tank is engineered to change that. Designed specifically for the 2004–2017 Dyna family, this tank provides a massive 5.1-gallon reservoir, allowing you to stay on the road while others are searching for the next pump. This is the definitive upgrade for riders who want to maintain the aggressive, muscular “Bobbed” look while gaining the range of a dedicated touring machine.

Precision Fitment and OEM Compatibility

When it comes to fuel tanks, precision is everything. This V-Twin Mfg. unit is a high-quality reproduction and replacement for OEM part numbers 61593-04 and 61593-04A. It is built to accommodate the unique mounting requirements of the 2004 through 2017 Dyna frames, ensuring that you don’t have to perform extensive modifications to achieve a factory-level fit. Because this tank is designed for later-model Dynas, it features the necessary internal provisions for Fuel Injection (EFI) components. It utilizes your stock fuel pump, fuel lines, and mounting hardware, making the installation process straightforward for both professional mechanics and experienced garage builders.

Heavy-Duty Steel and Custom Styling

Crafted from premium, heavy-gauge steel, this one-piece tank is designed to handle the high-torque vibrations of the Twin Cam engine. The “Bobbed” styling offers a wider, more substantial profile that perfectly complements the beefy front ends of the Fat Bob and Wide Glide. The tank arrives in a raw steel finish, providing a clean canvas for your custom paint vision. Whether you are aiming for a traditional gloss black finish or a complex, one-of-a-kind custom airbrush design, the smooth, uniform surface of this tank ensures that your bodywork process is as efficient as possible. The single-cap design is intended for use with standard screw-in style gas caps, maintaining a clean and uncluttered top line.

Technical Specifications and Fuel Management

Critical Preparation for Custom Painters

To ensure a show-quality result that lasts for years, proper preparation of the raw steel is vital. Like all aftermarket fuel tanks, this V-Twin Mfg. unit must be pressure tested and internally sealed before any paint is applied. Using a high-quality internal tank liner protects the metal from the corrosive effects of ethanol-enriched fuels and prevents the risk of internal rust or minor leaks that could ruin an expensive custom paint job. We also highly recommend a “dry fit” on your Dyna frame before painting to check for clearance against your handlebars, triple trees, and specific seat choice. This proactive step ensures a perfect, “bolt-on” experience once your paint has cured.
