Brian Crower Mitsubishi 4B11 Evo X Titanium Retainers

If you're rebuilding the top end of your 4B11 engine in your Mitsubishi Lancer, especially for performance applications, you'll want to consider upgrading your valve retainers. These Brian Crower titanium retainers are designed to handle the increased stresses that come with higher RPMs and more aggressive camshaft profiles. They are a well-built component that helps ensure your valvetrain stays stable under demanding conditions.

Titanium is significantly lighter than the stock steel retainers. This reduction in mass at the top of the valve spring means less inertia, allowing the spring to control the valve more effectively, especially as engine speeds climb. Brian Crower is known for making solid valvetrain components, and these retainers are no exception. They are a popular choice for tuners and builders looking for reliable parts for their performance builds.

When installing these, it's important to ensure your valve springs are properly matched to the retainer's dimensions and the engine's intended use. Always refer to the manufacturer's installation instructions for the most accurate guidance.
