Brian Crower Adjustable Cam Gears for Subaru EJ205/EJ257 - Left Exhaust Only

Brian Crower adjustable cam gears are for Subaru EJ205 and EJ257 engines, specifically the left exhaust camshaft position. If you're rebuilding the top end of your Subaru and want to dial in your camshaft timing precisely, these gears are a solid option. They allow you to make small adjustments to when the exhaust valves open and close relative to the piston's position, which can help optimize power delivery and engine response.

These gears are well-built from anodized aluminum, making them lightweight yet strong. The laser-etched degree marks are clear and easy to read, helping you make accurate adjustments during installation. They use a robust locking mechanism to ensure your settings stay put once you've found the sweet spot for your engine build. Keep in mind that these are for the left exhaust side only, so you'll need a matching gear for the right exhaust side if you're adjusting both.

Because these are adjustable, they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and torque specifications.
