This kit allows you to synchronize your Stromberg carburetors by comparing the piston lift in the vacuum chambers with a pair of dial indicators and adjusting the airflow accordingly.  The kit includes stainless collars with thumbscrews, a pair of dial indicators and indicator extensions including longer tips.

This only fits Strombergs that are similar to the SU design.  Make sure your carburetors have a top like the one shown in the picture.

For quad equipped cars like Series II and III E-types, order two kits.
