Info
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.

Summary:
This worked well for me, but I did not test the calibration. Hopefully this works well for everyone, but it's hard to say because poor reviews rarely get posted as I have found with other products.
Yes, I recommend this product.

Summary:
I wanted to be able to test springs w/o a trip to my engine builder. LS1 with AFR heads, and 20k miles. Measured against the spec and seat pressure was low by >20 lbs. Tested a new PAC spring and was dead on, both seat and at .600 lift. I'm confident the tool is accurate.
Yes, I recommend this product.
