SPRING KITS

Valve spring performance is critical to engine durability, RPM capability, and valvetrain control. GSC Power-Division spring kits are engineered to provide the stability required for aggressive cam profiles, elevated boost levels, extended RPM ranges, and demanding racing environments.

Our spring systems are developed with careful attention to harmonics, installed loads, open pressures, coil dynamics, retainer compatibility, and long-term durability. Many GSC applications utilize advanced conical spring technology to improve damping characteristics, reduce harmonics, minimize spring stress, and maintain superior valve control at elevated engine speeds. The result is increased confidence when pushing horsepower, RPM, and boost beyond conventional limits.

Frequently Asked Questions

Why should I upgrade my valve springs?

Upgraded valve springs provide greater valve control at high RPM, higher boost pressures, and with more aggressive camshaft profiles. This helps prevent valve float and improves reliability.

What are the benefits of conical valve springs?

Conical valve springs offer reduced retainer mass, improved natural frequency, greater stability, and improved high-RPM performance compared to traditional cylindrical springs or beehive springs.

Do your spring kits include retainers?

Many GSC spring kits include titanium retainers. Refer to individual product descriptions for complete kit contents.

Can I reuse my factory retainers?

Only if specifically stated. Most performance applications should utilize the retainers recommended for the spring package.
