Valve Spring Micrometers
Accurate to .001", our 1.600"-2.200" range spring micrometer, is the most precise way to measure installed height. Essential for ensuring seat and open pressures or calculating coil bind, this mic is a must-have for any valvetrain project.
This is by far the quickest, easiest, and most accurate way to measure valve spring installed height. Comp Cams Height Micrometers install just like a valve spring, and then the tool is expanded until it has fully seated the valve, locks, and retainer. This simulated installation is what allows ultra precise readings. The tool is then read like a micrometer and is accurate to .001.
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
