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.

The product's quality and functionality are highlighted in its ability to display consistent readings, working effectively for both old and new springs. It allows for repeatability in compressing the spring to installed and valve open heights with remarkable precision. Customers recommend it for any engine enthusiast's kit due to its practicality and superior performance compared to similar products on the market. Nevertheless, a solitary issue related to oil leakage was reported during usage. Overall, users deem it a great value for money and a necessity for every garage.

Need to know your pressures?

Simply remove your valve springs from the head, put spring, cap, and gauge in vice. Measure length at seat pressure, tighten to lift dimension then read the gauge. My cam call for a maximum of #280 at full lift. The heads called out #290 at max lift for springs. My cam lift of .501" came to 250#. Right in the sweet spot for lifters and cam. Cost was good.

I bought this product to test the springs in a j-series Honda engine that I was rebuilding. (Springs were fine) The oil filled gauge makes it easy to read, and its small size means I can stash it away without taking up a ton of room. (I rarely have a need to use this)

I needed an affordable valve spring tester to ck some replacement springs specs with the cam card. I started out using the vise to do the compression but ended up switching to my drill press for better consistency. I'm very satisfied with this piece of equipment and glad to have it on the shelf.

Does the price include the rear part of the gauge also or is this the gauge by it self ? In other words is it a complete gauge ready to use as in the second picture. Thank you Ken

Is the spring pressure of the spring being tested read directly from the gauge? (example, 300 pounds spring tension equals 300 pounds needle reading on gauge)? What is the spring reading limit? Does this tester include a calibrating spring? Thanks, David
