COMP Cams 4903 Indicator Bracket for Rimac Valve Spring Tester

4903 - Bracket, for Spring Checker.

These bench top testers are really the only sure way to check valve spring pressure. This model will handle springs up to 2” diameter and 4 ½” free length, so its useful for more than just checking valve springs. The 0-1000lb. range by 5 lb. increment scale allows you to check open pressure as well as seat pressure. The use of a test spring is highly recommended as the unit can be tested and recalibrated in the field (sold separately). Also sold separately is an indicator bracket for this spring tester
