This COMP Cams titanium valve spring retainer is precision machined from 6AL4V alloy for LS1 and similar 8mm valve engines, offering higher stiffness and minimal warpage at elevated RPM. The 7-degree design matches COMP Cams' 26921 valve spring. It’s intended to reduce rotating mass compared with steel retainers and provide consistent fit and durability for high‑revving valvetrain setups.
