Billet Vortech Tensioner Adj'er What every Vortech owner has always wanted. An easier way to adjust your Supercharger belt. This billet adjuster mounts easily to your Supercharger and allows you to loosen the tensioner bolts and adjust tension with the Billet adjuster. This was designed on the 86-93 Mustang but could work on other applications. For this to work on your application you must have the third tensioner bolt hole from the right (looking at the pulley) open and not covered by the tensioner bracket. Includes Billet Aluminum Braket with adjusting screw, lock nut, and mounting screw. (Actual Tensioner Not Included)
