Gasbox: Custom Parts for Chopper and Harley-Davidson Builds
Gasbox is a Cleveland, Ohio-based maker of custom parts and accessories for Harley-Davidson motorcycles, with a particular focus on vintage and chopper-style builds. The brand is a familiar name among custom builders who want hardware that looks right on a stripped-down, rigid-frame machine and fits properly the first time.
What Gasbox Is Known For
Gasbox has built its reputation on fabrication-minded parts for Sportster, Big Twin and other Harley platforms. The wider catalog is centered on chopper-specific components such as full rigid frames, oil tanks, battery boxes, mounts and the hardware needed to build around them. Sissy bars and license plate mounts are among its best-known products, and they are the heart of the selection shown here.
Sissy Bars
A sissy bar is the upright backrest that mounts behind the seat. It adds a classic chopper silhouette, and it also gives a passenger something to lean against. Gasbox offers bolt-on designs that go on without welding, which makes them a practical choice for riders who want a period-correct look without fabrication work. Examples include the Chopper Bolt-On Sissy Bar for Harley Sportster XL and a black powder-coated Chopper Bolt-On Sissy Bar. Powder coating gives a durable, even finish that resists chips and weather better than many basic paint jobs.
License Plate Brackets
Relocating a license plate is one of the first steps in cleaning up the rear of a custom bike. The Gasbox Shock Mount License Plate Bracket bolts to the lower shock bolt, moving the plate out of the way of the fender and any rear lighting. It is made of powder-coated steel and is designed around a 1/2 inch diameter shock bolt, a common size on many motorcycles including Harley-Davidsons. Always check your own shock hardware size before ordering to confirm fitment.
Shopping Tips for Gasbox Parts
- Confirm your model and year. Frame geometry and mounting points differ between Sportsters, Dynas, Softails and Big Twins, so match the part to your exact application.
- Check hardware sizes. Shock bolts, axle diameters and fender mounting points vary, and brackets are designed around specific dimensions.
- Plan the whole rear end. Sissy bar, plate position, lighting and fender should work together, so think through the layout before buying individual pieces.
Whether you are restoring a vintage Sportster or building a rigid chopper from the frame up, the Gasbox range offers focused, builder-oriented parts that suit the custom Harley scene.
