Oil Tanks

Oil tanks built in our Sioux Falls shop. The Pill and barrel-style round tanks suit chopper and bobber frames, the under-trans tank tucks below a Big Twin transmission, and the drop-seat Sportster tanks are shaped for our weld-on hardtails and for full frames. Each is welded here. Alloy Art polyurethane and Mid-USA rubber tank grommets are stocked for the mounts. Caps, bungs and fittings are in the neighboring sections.
