Key Features & Benefits
Designed for High Boost & High RPM Stability
Engineered to maintain precise valve control under aggressive cam profiles and increased boost levels, minimizing valve float and ensuring consistent performance at high engine speeds.
High-Temperature Stainless Steel Valves
The Kelford valves are manufactured from premium austenitic stainless steel alloys specifically developed for high-performance engine applications.
- Alloy composition includes chromium, nickel, and tungsten for enhanced strength and thermal stability
- Excellent resistance to heat, oxidation, and fatigue under extreme exhaust gas temperatures
- Maintains structural integrity in high cylinder pressure and forced induction environments
Triple-Groove Valve Lock Design (Drop-In Compatibility)
- Valves feature a precision triple-groove keeper design at the stem
- Fully compatible with OEM valve locks (keepers)
- No additional valve locks required, simplifying installation and reducing build complexity
Precision Forged & Heat Treated
- Forged construction ensures optimal grain structure and durability
- Advanced heat treatment process improves tensile strength and fatigue resistance
- Designed for long service life in demanding conditions
Beehive Valve Spring Technology
Kelford’s beehive spring design offers significant advantages over traditional spring setups:
- Reduced valvetrain mass for improved engine response
- Increased stability at high RPM
- Lower harmonic resonance for smoother operation and reduced wear
Complete Sealing Solution
- Includes Supertech valve stem seals for both intake and exhaust
- Ensures proper oil control and long-term reliability
