Ferrea 02-08 Honda CRF450 4.965mm Valve Stem Exhaust Titanium Retainers - Set of 2

If you're rebuilding the top end of your 02-08 Honda CRF450, especially if you're looking to shed some weight and improve valve train response, these Ferrea titanium exhaust valve retainers are a solid choice. They replace the stock retainers, offering a significant weight reduction that can make a difference in how quickly the valve train can operate at higher RPMs. This is particularly important for performance-oriented builds where every bit of responsiveness counts.

Ferrea is known for making well-built engine components, and these retainers are no exception. They're made from strong titanium, which is not only lighter than steel but also very durable. The 4.965mm size is specific to the exhaust valves on these CRF450 models, ensuring a direct fit when you're putting your cylinder head back together. Using titanium here helps reduce the overall mass of the valvetrain, which can lead to less stress on other components and potentially allow for higher rev limits.

When installing these, make sure you have the correct tools to handle the valve springs. It's a good idea to refer to your service manual for the specific procedure for your CRF450. This set includes two retainers, enough for one exhaust valve. If you're working on both exhaust valves, you'll need to order two sets.
