| 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, or call our technical staff. |
| Making correct measurements before assembly is critical as many variables are present to catch the unwary. |
