Rowe U.S.A. Parts & Accessories

Rowe U.S.A. make precision engine internals — black melonite intake and exhaust valves are the headline product, with direct-fit replacements for Big Twin Evo and other common platforms. The melonite finish handles heat better than chromed valves and stays clean longer in service.

Catalogue extends into lighting, fuel system parts, and driveline components, but the valve work is what brings most builders back. If you're doing a head rebuild or fitting bigger valves on a high-mileage motor, this is the kit to spec.
