Height Mic - 1.400 to 2.000

The PAC Racing Springs Height Mic 1.400 to 2.000 in Range (PAC-T901) is a precision valve spring height gauge engineered for engine builders, performance technicians, and serious automotive enthusiasts. This 0.001-inch scale instrument provides the precision measurement necessary when blueprinting beehive springs and validating spring installation heights during high-performance engine assembly, restoration, and quality control operations.

The gauge covers the 1.400 to 2.000-inch measurement range with 0.001-inch incremental accuracy, making it essential for verifying that valve spring heights fall within manufacturer specifications. The blue anodized finish provides corrosion resistance during repeated use in shop environments and protects the instrument from oxidation during storage. The compact design—measuring 2.35 x 2.3 x 3.85 inches and weighing only 0.2 lbs—allows technicians to keep this tool easily accessible in the toolbox or portable engine-building kit without adding bulk.

Engine builders, race shops, and performance rebuilders rely on PAC Racing Springs components and measurement tools to achieve the precision demanded by competition engines and street performance builds. This height mic is specifically designed for beehive spring applications, where exact spring height directly affects valve control, rocker arm geometry, and overall engine stability. Whether you're blueprinting a race engine, restoring a classic muscle car, or validating a crate engine installation, accurate spring height measurement ensures your valvetrain operates within design tolerances and prevents costly installation errors.

PAC Racing Springs is recognized throughout the automotive performance industry for manufacturing valvetrain components and measurement instruments that meet the exacting standards of professional builders and enthusiasts. This gauge represents the same precision tooling standard expected from a manufacturer whose products are foundational to engine performance shops nationwide.
