High-RPM Stability for Subaru EJ Series Engines

Protect your Subaru EJ205 or EJ257 engine from valve float with the Brian Crower Single Spring and Titanium Retainer Kit. Designed for high-performance builds, this kit provides the necessary seat pressure to keep valves closed at high RPMs, preventing catastrophic engine failure. The inclusion of lightweight titanium retainers reduces valvetrain mass, allowing for faster revs and improved throttle response.

Why Choose This Valvetrain Kit?

• Titanium Retainers: Significantly lighter than steel to reduce reciprocating mass
• High-Performance Springs: Engineered to handle increased lift and high RPMs
• Compatibility: Perfect fit for Subaru EJ205 (WRX) and EJ257 (STi) engines
• Reliability: Essential for engines with upgraded camshafts
• Longevity: Reduces wear on valve guides and seats

Whether you are running an aggressive cam profile or pushing higher boost levels, the stock valvetrain is often the weak point. Brian Crower’s valvetrain components are industry-standard for Subaru enthusiasts who demand reliability under pressure. By upgrading to this kit, you ensure that your engine can safely reach its power potential without the risk of valve float. This kit is a must-have for any serious Subaru build, from daily-driven WRXs to full-blown STi track cars. Equip your engine with the best valvetrain components available at GGCRACING.
