This kit allows you to synchronize your SU carburetors by comparing the piston lift in the vacuum chambers with dial indicators and adjusting the airflow accordingly.  The kit includes brass collars (not stainless as shown) with thumbscrews, a pair of dial indicators and indicator extensions including longer tips.

This kit is appropriate for '77 and up Shadow II's, Silver Wraiths, carbureted Spirit/Spurs and other cars with SU HIF7's. Please see our "links" tab for a video describing the synchronization process.
