Product Description
Brian Tooley Racing BTR GEN III HEMI Valve Spring Height Mic
Valve Spring Height Micrometer for 2003-Later 5.7L 6.1L 6.2L 6.4L Hemi Dodge Chrysler Jeep Engines
Measure installed valve spring height more accurately and confidently with the Brian Tooley Racing BTR GEN III HEMI Valve Spring Height Mic. Designed specifically for 2003-later Gen III Hemi Dodge, Chrysler, and Jeep engines, this spring height micrometer helps engine builders, cylinder head shops, and performance installers measure valve spring installed height during camshaft swaps, valve spring upgrades, cylinder head assembly, and valvetrain setup. Brian Tooley Racing designed this tool with several improvements over traditional spring height mics, including .100" height change per revolution, an easier-to-grip top, and laser-etched markings on a black background for easier readings.
Key Features & Benefits
- Gen III HEMI-Specific Spring Height Mic: This Brian Tooley Racing valve spring height micrometer is designed for 2003-later Gen III Hemi engine applications. It gives engine builders and installers a purpose-built measuring tool for checking installed height during valve spring upgrades, cylinder head work, and valvetrain setup.
- .100" Height Change Per Revolution: Brian Tooley Racing designed this mic with a more desirable .100" height change per revolution. This helps reduce the chances of reading errors commonly associated with spring height micrometers that use .050" height change per revolution.
- Easy-to-Grip Top Design: The unique top features indentations for your fingers, making the micrometer easier to tighten and adjust during use. This design gives users a more controlled feel compared to the industry-standard knurled top found on many traditional spring height mics.
- Laser-Etched Measurement Markings: Laser etching on a black background helps make measurement readings easier to see while setting up valve springs. Clearer markings are especially useful when checking installed height repeatedly across multiple cylinders during engine assembly or cylinder head service.
- Useful for Camshaft and Spring Upgrades: Proper installed height measurement is an important part of matching valve springs to the intended camshaft and valvetrain package. This BTR tool is a practical addition for Hemi cam swaps, spring kit installs, cylinder head refreshes, and performance engine builds.
