The Brian Crower titanium valve spring retainer for the Nissan RB26DET is a single, lightweight retainer made to retain valve springs in high‑revving applications. Titanium construction reduces reciprocating mass compared with standard retainers and supports stable valve control at elevated engine speeds. It’s intended as a direct replacement component for RB26DET engines where stronger, lighter valvetrain hardware is required.
