By upgrading to these dual cylindrical valve springs, you’ll benefit from improved valve control at higher RPMs, reducing the risk of valve float and ensuring consistent engine performance. This kit is ideal for enthusiasts looking to support increased power output or those who demand greater valvetrain stability during extended high-rev operation.
Key Features:
The GSC Power Division Dual Cylindrical Valve Spring Kit offers a range of technical advantages that improve engine response and reliability:
- Dual cylindrical spring design provides enhanced valve control and stability at high RPMs.
- Manufactured with high-quality spring steel for durability and long service life.
- Specifically engineered for the Subaru FA20 engine to ensure perfect fitment and optimal performance.
- Reduces valve float, allowing for safer operation at elevated engine speeds.
- Supports performance modifications by maintaining valvetrain integrity under increased load.
- Precision wound springs maintain consistent spring rates for reliable valve timing.
- Ideal for both street performance and track applications where engine responsiveness is critical.
Construction & Design:
The valve springs are crafted from premium spring steel, designed to withstand the stresses of high RPM operation without compromising durability. The dual cylindrical configuration balances spring force and stability, reducing harmonic vibrations and improving valve train control. This design ensures that the springs maintain consistent pressure on the valves, preventing valve float and improving throttle response.
Each spring is precision wound and heat-treated to meet strict quality standards, ensuring reliable performance and longevity. The kit is engineered to fit directly onto the FA20 cylinder head without modification, maintaining OEM specifications while enhancing performance.
Installation & Fitment:
This valve spring kit is a direct replacement for the factory springs on the Subaru FA20 engine and fits the following vehicles:
- 2013–2020 Subaru BRZ
- 2013–2016 Scion FR-S
- 2017–2020 Toyota 86
Installation requires removal of the cylinder head components and should be performed by a professional or experienced technician. No modifications to the engine or cylinder head are necessary, and the springs install using factory mounting points. Proper valve spring compressor tools are recommended for safe installation.
