Ferrea 08-09 Honda CRF250R 4.47mm Valve Stem Exhaust Titanium Retainers - Set of 2

Crafted from aerospace-grade titanium, these Ferrea valve stem retainers are specifically made for the 4.47mm exhaust valves on your 2008-2009 Honda CRF250R. Titanium is a popular choice for performance engine components because it's incredibly strong yet surprisingly lightweight, which helps reduce valve train mass. Less mass means the valve train can operate more reliably at higher RPMs, which is crucial for getting the most out of your engine.

This set includes two retainers, enough for a pair of exhaust valves. Ferrea is well-known for making solid engine parts, and these retainers are built to handle the demands of a performance-oriented engine. They are designed to fit right into your existing valve train setup, making them a straightforward replacement when you're rebuilding or upgrading your engine's top end.
