Brian Crower Mitsubishi 4B11T Evolution X Single Spring & Titanium Retainer Kit

If you're pushing your 2008 or 2010-2014 Mitsubishi Lancer's 4B11T engine hard, especially at higher RPMs, you'll want to make sure your valvetrain can keep up. This single spring and titanium retainer kit from Brian Crower is designed to handle those demands. It helps ensure your valves close reliably when the engine is spinning fast, which is crucial for maintaining power and preventing damage.

Brian Crower is known for making well-built engine components, and this kit is no exception. The titanium retainers are significantly lighter than stock steel ones, which reduces the overall mass the valve spring has to control. This means the spring can do a better job of keeping the valve seated, even under aggressive driving conditions. The springs themselves are engineered for improved performance over stock, giving you more confidence when you're revving the engine out.

This kit is a solid option for anyone looking to upgrade their Lancer's valvetrain for more demanding use. It's a direct fit for the specified Lancer models, making installation straightforward for someone familiar with engine work.
