Proform Parts Bb1000 Valve Spring Tester

Since the 1920's RIMAC has been the industry standard when it comes to valve spring testing tools. Rimac's famous flagship "Big Blue" spring tester is now available once again! In performance and racing applications. valve spring pressure (open and closed) is one of the most important specs that need to be checked and adjusted during the initial engine build. Even a single quarter-mile run on the drag strip can cause springs to lose their tension in high output engines. Some professional racers check and replace valve springs after every run because even a minimal spring-rate change can mean dramatic results at the race track and the difference between getting the win and second place.
