For over 30 years we have been manufacturing extension fork tubes. This is a product we are very familiar with and we cover every Harley Davidson fork tube model all the way back to 1949. Our tubes start with special ordered DOM 1026 steel tubing that we centerless grind the outside diameter to OEM specifications and machine to exact ID specs. We buff the material to a mirror finish and chrome plate the final product to a show chrome finish. We offer sizes from 2” under to 18” over.
