On Head Valve Spring Tester

The Most Accurate On Head Valve Spring Tester

The continuing search for horsepower in today's racing engines require more radical camshaft profiles than ever, which are very demanding on valve springs.  Many people neglect valve spring maintenance, which not only robs power, but is damaging to your valve train. Until now, the only way to accurately measure valve spring pressure was to disassemble each spring and check it on a bench tester. There are several companies that claim to have an accurate method of testing springs on an assembled engine, but many claims fall short. At Buxton Engineering, we feel that we have revolutionized the process for on head spring testing. We guarantee this tool to give bench tester results, with no second guess.

  • Test 16 valve springs in minutes with bench  tester accuracy.

  • Works on most wedge head configurations. Shaft or stud mounted rocker arms.

  • CNC machined from billet 6061-T6 aircraft aluminum.
