New valve springs with larger diameters require new retainers to handle
the higher pressures developed by the springs. COMP Cams steel valve
spring retainers are the solution. Precision-machined from 4140
chromoly and finished in black oxide, these retainers are specifically
designed for positive location when combined with COMP Cams'
high-quality valve springs. They're available for single, double, and
triple-spring applications.
