Upgrade your Honda B-Series valvetrain with the GSC Power Division Exhaust Valves, featuring a 28mm head and a precision-engineered 6mm stem. Designed specifically for the B16A, B17A, and B18C VTEC engines, these valves offer a significant upgrade over stock components. The 6mm stem design is optimized for reduced weight and improved valve train stability, allowing for higher RPM limits and more reliable performance in competitive racing environments.
GSC Power Division is a leader in valvetrain technology, and these exhaust valves reflect their commitment to quality and innovation. The chrome alloy construction provides excellent resistance to the high temperatures found in the exhaust port, ensuring that your valves maintain their shape and seal under extreme conditions. The 6mm stem reduces reciprocating mass, which helps prevent valve float at high engine speeds, making these an essential upgrade for any performance-oriented build. Whether you are building a track-day hero or a high-output street machine, these valves provide the reliability and performance you need. Trust your engine build to the experts and find these GSC Power Division components at GGCRACING.
