One-Piece Tanks

The Drag Specialties Extended Gas Tank is a one-piece, extended-length fuel tank designed for Harley-Davidson models. Built from durable 16-gauge stamped steel, this tank increases fuel capacity while delivering a stretched custom look ideal for performance builds and restorations.

Featuring a 2-inch extended design and approximately 5.1 gallons of fuel capacity, this tank offers increased range without sacrificing classic styling. The tank is supplied in a raw finish, allowing proper fitting, pressure testing, and preparation prior to final paint.

Designed for carbureted applications, this tank uses a screw-in cap design and may require minor seat or sending unit modifications depending on the model and setup.
