Next time you are needing to locate Top Dead Center on your hot rod's engine, let Mr. Gasket lend a hand. Our TDC indicator threads into 14mm or 18mm threaded spark plug holes. It whistles on the compression stroke and stops whistling at approximately Top Dead Center. Just a few of the many examples of when needed are, timing chain inspection or replacement, distributor installation and cylinder leak down.

Processing & Shipping Overview

Processing occurs before shipping.

Most in-stock items typically process within 2–3 business days before shipment or pickup. Expedited shipping options affect transit time after an order ships and do not speed up processing.

Made-to-order, special-order, vendor drop-ship, and freight items require additional processing time before shipping. Any extended lead times will be noted on the product page when applicable.

For the most up-to-date order status or lead time questions, please contact sales@smgspeed.com or use live chat during business hours.
