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. 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.

Perfect for what I needed to do. Check that my valve springs were within spec.

Appears very stout and well made. Like the liquid damped gauge. Have yet to use it on springs, but it appears to be calibrated according to a test weight. I had my doubts since this is the cheapest one on Amazon, but I am impressed so far. Time will tell. Arrived promptly and damage free. Bubble wrap inside cardboard, and a free sticker for the tool box!
