Precision machined from chromemoly steel then black oxided, these 7 degree retainers are designed specifically for 11/32" valve engines with 1.437"-1.500" outer diameter valve springs like our 982, 990, 972, 901, 988 and 950 springs.
Valve springs with larger diameters require retainers to handle the higher pressures developed by the springs. COMP Cams steel retainers are the perfect solution. This 7? steel retainer for Chevy, Small Block Ford, Olds and Pontiac applications is precision machined from 4140 chromemoly steel and finished in black oxide. This precision retainer is specifically designed for positive location when combined with COMP Cams high-quality valve springs.
