Ferrea 05-08 Harley-Davidson Twin Cam Titanium Retainers - Set of 8

These are Ferrea titanium valve spring retainers, a set of eight designed for 2005 through 2008 Harley-Davidson Twin Cam engines. They are a crucial component for your engine's valvetrain, working with the valve springs to keep everything operating smoothly under high RPMs and stress.

Crafted from titanium, these retainers are notably lighter than stock steel retainers. This reduction in weight at the valvetrain's top end helps to decrease rotational mass, which can lead to improved engine response and allow the valvetrain to operate more reliably at higher engine speeds. Ferrea is known for making well-built engine components, and these retainers are no exception, offering a solid option for anyone rebuilding or upgrading their Twin Cam engine.
