This Brian Crower titanium valve retainer is specified for Mitsubishi 4G63 engines found in Eclipse and Evo models. Supplied as a single titanium retainer, it functions as a lightweight valve train component intended to retain valve springs in performance or replacement applications where the 4G63 valvetrain is used. Titanium construction reduces reciprocating mass while maintaining retainer function in high‑rev valve train environments.
