Piston Height Measuring Tool – 65‑85 cc Engines (Dial Indicator Not Included)

The VHM AM34012 piston height measuring tool is designed for exact measurement of piston deck height in 65‑85 cc two‑stroke engines when using performance cylinder heads and inserts. The correct piston height is critical to ensure optimal squish clearance and combustion chamber volume. The tool includes an upper measuring part and a lower calibration part: the lower is used for calibration, and the upper part is placed on the cylinder to measure the piston height relative to the head or insert. The dial indicator is not included and must be purchased separately. This tool is ideal for engine builders and tuners who demand accuracy and consistency, particularly when working with high‑performance components and setups.
