Overview:

The GSC Power Division Single Beehive Spring Kit is a precision-engineered valve spring upgrade designed specifically for the Subaru BRZ (2013–2017) and Toyota 86 (2017) equipped with the FA20 engine. This kit is ideal for enthusiasts seeking enhanced valvetrain stability and reliability during high RPM operation, whether for spirited street driving or track use. By replacing the factory valve springs with GSC’s single beehive springs, users benefit from improved valve control, reduced spring surge, and increased durability under demanding conditions.

Featuring titanium retainers and chromoly seats, this kit offers a lightweight yet robust solution that reduces valvetrain mass and enhances overall engine responsiveness. It is a popular upgrade among tuners and racers aiming to safely increase engine performance without compromising reliability.

Key Features:

The GSC Power Division Single Beehive Spring Kit combines advanced materials and design to deliver superior valvetrain performance. Key features include:

• Single beehive spring design for reduced weight and improved spring harmonics
• Titanium retainers to minimize valvetrain mass and increase RPM capability
• Chromoly steel spring seats for enhanced durability and secure spring positioning
• Precision wound springs engineered to maintain consistent seat pressure and prevent coil bind
• Optimized for the FA20 engine found in Subaru BRZ and Toyota 86 models
• Improved valve control reduces the risk of valve float at high RPM
• Designed to work seamlessly with factory or upgraded valvetrain components
• Manufactured with strict quality control standards to ensure reliability and longevity

Construction & Design:

The springs in this kit are crafted from high-quality spring steel with a single beehive shape that tapers the coils to reduce weight and improve harmonic behavior. This design helps to eliminate spring surge and resonance that can lead to valve float or component fatigue. The titanium retainers are precision-machined to be lightweight yet strong, significantly reducing the reciprocating mass in the valvetrain and allowing the engine to safely reach higher RPM limits.

Chromoly steel seats provide a durable and stable base for the springs, ensuring consistent spring alignment and pressure over extended use. The combination of these materials and engineering choices results in a valve spring kit that balances performance, reliability, and longevity for demanding driving conditions.

Installation & Fitment:

This valve spring kit is a direct fit for Subaru BRZ models from 2013 through 2017 and Toyota 86 models from 2017, all equipped with the FA20 engine. Installation requires removal of the cylinder head or valve cover depending on the service approach and should be performed by a qualified technician familiar with valvetrain components. Proper installation ensures optimal spring seating and valve timing accuracy.

No modifications to the engine or valvetrain are necessary when using this kit, making it a straightforward upgrade for enthusiasts looking to improve engine durability and performance potential.

What's Included:

• Set of single beehive valve springs
• Titanium valve spring retainers
