Overview:

The Brian Crower Single Valve Springs are precision-engineered performance components designed specifically for the FA20 engine found in the Subaru BRZ, Scion FR-S, and Toyota 86 models within the specified year ranges. These valve springs are ideal for enthusiasts seeking enhanced valve control and reliability during spirited driving or track use.

By upgrading to Brian Crower’s single valve springs, you’ll improve your engine’s ability to handle higher RPMs and aggressive cam profiles, reducing valve float and increasing overall durability. This makes them a perfect choice for daily drivers who want improved performance as well as racers looking for dependable valve train components.

Key Features:

Brian Crower valve springs offer a combination of durability, precision, and performance benefits tailored to the FA20 engine platform:

• Manufactured from high-quality spring steel for consistent spring rates and long-lasting performance.
• Designed to provide optimal valve control at elevated RPMs, minimizing valve float and bounce.
• Specifically engineered for the Subaru BRZ, Scion FR-S, and Toyota 86 FA20 engines to ensure perfect fitment and function.
• Single spring design simplifies installation and reduces valvetrain mass compared to dual springs.
• Supports aggressive camshaft profiles and higher engine speeds for enhanced power potential.
• Improves throttle response and engine reliability under demanding driving conditions.
• Precision wound and heat-treated for consistent performance and durability.

Construction & Design:

Brian Crower valve springs are crafted from premium spring steel and undergo rigorous heat treatment processes to achieve optimal strength and fatigue resistance. The single spring design reduces overall valvetrain weight, which helps improve engine responsiveness and reduces stress on related components.

Each spring is wound to exact specifications to maintain consistent spring rates and ensure reliable valve seating at high RPMs. This attention to detail supports enhanced engine performance and longevity, especially when paired with upgraded camshafts or forced induction setups.

Installation & Fitment:

These valve springs are a direct fit replacement for the factory springs on the Subaru BRZ, Scion FR-S, and Toyota 86 equipped with the FA20 engine. Installation requires standard valvetrain disassembly and reassembly procedures.

No modifications to the cylinder head or valve train components are necessary, making this an efficient upgrade for enthusiasts looking to improve engine performance without extensive machining or tuning.

• Direct bolt-on fitment for 2013–2020 Subaru BRZ, 2013–2016 Scion FR-S, and 2017–2020 Toyota 86 FA20 engines.
• No cutting, drilling, or special tuning required.
