Multi Range Billet Actuator

If you're looking to take your Mitsubishi EVO to the next level, this multi-rate billet actuator is where it's at. Built tough with a reinforced forged billet construction, it's designed to handle the demands of serious driving. With six springs included, you can really dial in your boost settings. Want to experiment? You can mix and match up to three springs for that sweet spot that works just right for your setup. Plus, the swivel type nipple makes routing hoses a breeze—no more fighting with awkward angles!

Billet Compressor Wheel

The new Billet Compressor Wheel is a game changer. Unlike those old cast wheels, this one is machined from aerospace-grade materials, so you know it's built to last. It's lightweight, which helps with turbo spool, and the thinner blades provide a larger surface area for airflow. Trust me, this means better performance and quicker response when you hit the gas. You'll notice the difference right away.
