Valve spring rate is important for performance and reliability in your engine. Don’t second guess or assume, check your spring rates easily and economically with our Valve Spring Tester Pressure Checker Gauge Tool.
Valve springs weaken and lose spring rate over time, especially on racing applications where engines see extended high RPM use. Even newer valve springs can show variability and weaken at different rates. Weak valve springs can lead to valve float, inadequate valve sealing, loss of horsepower and torque, and worse – loss of a cylinder or costly engine failure. Whether you’re building a new engine, rebuilding a motor, or maintaining a classic, knowing your valve spring rates is essential for performance and reliability.
Fortunately, testing the valve spring rate is easy and inexpensive. Our valve spring checker gauge tool works with a hydraulic press, or even a shop vise or drill press. The gauge rests directly on top of the valve spring, over a flat surface and reads pressure directly. We manufacture our gauge with an in-house precision CNC-machined 6061-T6, purple anodized aluminum housing and a machined steel piston. A liquid filled gauge gives you consistent measurement from 20-600 psi, and works directly with valve springs of 1-1/8” outer diameter. Larger diameter springs will work, but requires the spring retainer to sit against the piston.
- Economical tool for reliably testing important valve spring rates
- Easy use with hydraulic press (recommended), shop vise or drill press
- Works directly with valve springs of 1.125” O.D., larger valve springs require the retainer to sit against the piston.
- In-House machined 6061-T6 aluminum housing, with machined steel piston
- Liquid filled gauge for precision measurement from 20-600 psi
- Anodized purple finish
- Requires a flat surface. Hydrualic press recommended. However, a sturdy shop vise or drill press will work in most applications.
- Gauge reads from 20-600psi, but is most accurate above 30 psi.
- Gauge does not include a calibration spring.
