Ferrea 84-04 Harley-Davidson Evolution 1.85in Head Dia Competition Titanium Exhaust Valve - Set of 2

Crafted from aerospace-grade titanium, these Ferrea competition exhaust valves are built for performance in your Harley-Davidson Evolution engine from 1984-2004. The 1.85-inch head diameter is a specific design choice that helps improve airflow into the combustion chamber, which is crucial for getting the most out of your engine, especially when you're pushing it hard.

Using titanium means these valves are significantly lighter than their steel counterparts. This reduced weight allows your valvetrain to operate more freely at higher RPMs, reducing stress on components and potentially improving responsiveness. Ferrea is known for making well-built engine parts, and these valves are no exception, offering a solid option for anyone looking to rebuild or upgrade their Harley's top end. They are designed to fit right into the specified Evolution engines, making them a practical choice for serious engine work.
