Ogura Racing Clutch ORC-309D-01H | Metal Single Plate (Honda B-Series)

The ORC-309D-01H is the definitive clutch solution for the high-revving Honda B16 and B18 engines. Part of the Ogura Racing Clutch (ORC) 309 "Super Single" Metal Series, this kit is engineered to handle the demands of "light-tuned" performance cars while delivering the rapid-fire throttle response that B-Series owners crave.

Precision Engineering for B16 & B18

Replacing the heavy factory clutch and flywheel, the ORC-309D-01H utilizes a lightweight chromoly flywheel and a 200mm metal friction disc. This setup reduces rotational mass, allowing your engine to reach its VTEC crossover faster and with more precision. It is the perfect choice for the Civic Type R EK9, Integra Type R DC2, and high-performance B-Series street builds.

Why Upgrade to the ORC-309D-01H?

1. Instant Throttle Response The B-Series engine is famous for its high-RPM capabilities. By significantly reducing the weight of the rotating assembly with the 3.8kg flywheel, the ORC-309D-01H makes every rev sharper and more immediate.

2. The "Ogura Sound" Stand out at the meet. This metal clutch produces the signature "clinking" or "metallic jingle" when the pedal is depressed—a sound synonymous with high-end Japanese racing heritage.

3. Street-Friendly Engagement Despite its racing pedigree, the "D" (Damper) designation means this disc features a sprung hub. This dampens the engagement, providing a more manageable "half-clutch" feel for stop-and-go traffic compared to solid race discs.

4. Superior Heat Dissipation The metal friction material is designed to resist fading under extreme heat, making it ideal for spirited canyon runs, autocross, or track days where OEM clutches might slip.
