Stomski Sprocket Alignment Tool

Sprocket alignment on the 911 engine requires an accurate and repeatable ability to measure the offset of the sprockets and lay shaft. Simply using a straight edge and vernier calipers requires at least three hands and rarely produces precise measurements. Now, with the SR008, measuring sprocket alignment on the 911 engine has never been simpler, more accurate, or more repeatable. A precisely fabricated block of 6061 aluminum secures an oversized Starrett straight edge to enable easy and exact measurements. No more guessing or settling for "close enough." Includes custom caliper base, as well as thumb screws for mounting on all 911 engines including the 964.
