Buxton Engineering, Inc. - Bench-Pro Series Valve Spring Testers

Bench-Pro Valve Spring Tester

At Buxton Engineering we are proud to introduce our new Bench-Pro series valve spring testers. We collaborated with several top engine builders for their input on what aspects would make a better tester and after 2 years of development here it is. Don't even think about buying another tester until you check out one of these units.  Click on the Faq link at the bottom to see in detail some of the differences.
