What’s Included

Kelford Beehive Valve Spring Set (KVS276-BT)
Kelford Intake Valve Set
Kelford Exhaust Valve Set
Supertech Valve Stem Seals (Intake + Exhaust)

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
