Each 3/4" Tie Rod Sleeve is made out of 6061-T6 aluminum. 1" O.D. 3/4" RH and LH threads. All tubes have wrench flats and are bright gold anodized. Available in 1" increments from 8" to 27". Sold each.
Tech Tip: When assembling a tube, each heim end adds approximately 2" to the overall length (assuming the heim is screwed into the tube half way.) If you have a heim on each end of the tube, the working length from eye to eye will be approximately 4" longer overall than the tube. As a rule, your tube length will need to be 4" shorter than your working eye to eye length requirement.
