Brian Crower Mitsubishi 4G63 Eclipse/Evo Dual Springs / Titanium Retainers / Seat / Valve Seal Kit

Brian Crower is well-known for making strong internal engine components, and this dual valve spring kit for your Mitsubishi 4G63 engine is no exception. If you're building a performance engine for your 1990-1999 Eclipse, or any of the compatible DSM platforms, this kit is designed to handle higher RPMs and more aggressive camshaft profiles than stock springs can manage.

This kit includes everything you need to properly upgrade your valve springs. You get a set of dual springs, which offer better stability at high engine speeds by reducing the risk of valve float. The titanium retainers are significantly lighter than stock steel retainers, which reduces the overall mass of the valvetrain. Less reciprocating mass means the engine can rev more freely and safely. The kit also comes with the necessary seats and valve seals to ensure a complete and correct installation. This attention to detail means you're getting a well-built package that's ready to go into your performance build.

When you're pushing your 4G63 engine hard, the valvetrain is under a lot of stress. Upgrading to a dual spring setup like this Brian Crower kit is a smart move to ensure reliability and performance. Make sure to follow the manufacturer's installation instructions carefully, as proper installation is key to achieving the full benefits of this kit.
