VALVE SPRING APPLICATION
Crow Cams valve springs are made from aircraft quality alloy steels to give the best performance and reliability at a
reasonable price. They are specially designed to suit our high lift, high acceleration profiles. The following is a guide to
popular applications, if yours is not here see the spring specification chart on page 56 or call our technical staff.
Making correct measurements before assembly is critical as many variables are present to catch the unwary.
