- 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

FAQ
Fitment is confirmed for the applications listed in the Specs section above. Always confirm final fitment by year, market, and supporting hardware before ordering.
Yes. A professional calibration is required to safely control boost, fueling, torque limits, and thermal management.
Fueling, charge-air cooling, intake flow, downpipes, and drivetrain upgrades may be required depending on target power and fuel type.
The system is engineered for strong response, but daily drivability depends on calibration, fuel quality, supporting parts, and installation quality.
Warranty coverage applies to manufacturing defects under normal installation and operating conditions. Track use and improper calibration may affect coverage.
