Spun Aluminum 28"
Specialty Suspension's seamless aluminum air tanks have revolutionized welded air tank construction. They have adapted a new style of technology to create a non-welded tank. The metal spinning process has allowed us to manufacture our tanks from a single piece of extruded aluminum tube. This technique of closing both ends of the tube using the base material creates a true seamless tank. The Flow Forming Technology used on the port holes reforms the base metal inward into the tank giving a superior surface area for threading. The standard mounting hardware gives the consumer a limitless range of mounting positions and angles to accommodate most mounting situations. Manufactured in Fresno, CA
