Skunk2's Pro Series titanium retainers replace the factory steel retainers on the K-series and F-series VTEC head, cutting reciprocating valvetrain mass by roughly 42 percent for more horsepower and improved high-rpm stability. Radius-cut edges add rocker arm clearance, and lightening grooves with a reduced overall height further trim weight and improve valve seal clearance. Each retainer is CNC machined from certified titanium, individually inspected, and serialized.
