Acculign has been manufacturing its Benchmark Gauge Set for the hot alignment of turbomachinery since 1971. The Acculign Benchmark Gauge (commonly referred to as an Essinger Bar, after its inventor, Jack Essinger) has gained wide acceptance by industrial users.  A partial list of users of Acculign equipment can be found in the brochure for the gauge available on this site.

Acculign is proud to offer billet motorcycle products, including a unique line of adjustable rearsets.  Due to their dual eccentric design (US patent #6688629), these rearsets offer unparalleled fineness of adjustment.  I personally CNC machine each piece with tight tolerances, in small quantities, and feel confident that Acculign accessories are among the highest quality after-market motorcycle products available.
