What is the main advantage of a beehive valve spring design?

The beehive shape allows for a lighter retainer and spring compared to traditional dual springs. This reduction in mass helps the valvetrain respond more quickly to camshaft profiles, especially at higher RPMs.

What kind of camshafts are these springs designed for?

These valve springs are designed to handle the demands of performance camshafts, particularly those with higher lift profiles. They help ensure reliable valve closure even with more aggressive camshafts.

Does this kit include everything needed for installation?

This kit includes the valve springs and retainers necessary for replacement. However, it's always recommended to consult the manufacturer's installation guide for a complete list of required tools and any additional components or sealants that may be needed for proper installation.

Product Details

This is the Supertech Subaru WRX/STi 16V Single Beehive Valve Spring Kit, part number SPRK-TS1015-BE-SU3. If you're rebuilding the top end of your Subaru WRX or STi engine, especially if you're planning on higher lift camshafts or increased RPM limits, a well-built valve spring kit like this is essential. These springs are designed to handle the demands of performance camshafts and higher engine speeds, ensuring your valves close reliably and prevent valve float, which can lead to serious engine damage.

Supertech uses quality materials and advanced manufacturing processes to create these beehive-style valve springs. The beehive shape allows for a lighter retainer and spring, which reduces overall valvetrain mass. This reduction in mass helps the valvetrain respond more quickly to camshaft profiles, especially at higher RPMs. The kit includes everything needed to replace the stock valve springs, ensuring a direct fit for your Subaru WRX or STi engine. Proper installation is key, so always refer to the manufacturer's detailed installation instructions for specific procedures and torque specifications.

When building a performance engine, the valve springs are a critical component that often gets overlooked. This Supertech kit offers a solid option for enthusiasts looking to ensure their valvetrain can keep up with their engine's potential. Make sure you have the right tools and knowledge for a successful installation, or consider having a professional mechanic handle the job to ensure optimal performance and reliability.
