• Precision-engineered components maintain valve control at elevated engine speeds
• Compatible with factory valve stems and guides for seamless integration

Construction & Design

The kit features high-quality steel springs formed into a conical shape, which significantly reduces spring surge and harmonic vibrations commonly experienced with traditional cylindrical springs. This innovative design enhances valvetrain stability and extends component life under demanding operating conditions.

Included steel retainers and valve locks are manufactured to exacting tolerances to ensure secure valve retention and consistent performance. Valve seals and seats are engineered for a precise fit without requiring machining, preserving factory sealing integrity and simplifying installation.

For those seeking further performance gains, titanium retainers are available as an upgrade option. These provide a superior strength-to-weight ratio, reducing valvetrain mass and enabling higher RPM operation without compromising durability.
