Skunk2 Alpha Valve Spring & Titanium Retainer Kit – Honda K-Series K20 K24
Upgrade the valvetrain of your Honda K-Series performance engine with the Skunk2 Alpha Valve Spring & Titanium Retainer Kit, part number 344-05-1410.
Designed for performance-focused Honda K-Series engines, the Alpha kit combines Skunk2’s dual valve springs with lightweight titanium retainers to improve high-RPM valvetrain stability while reducing moving valvetrain mass.
The Alpha Valve Springs use inner and outer springs with different frequencies and a slight interference fit between the springs. This design is intended to help prevent valve float and maintain valvetrain stability at engine speeds exceeding 10,000 rpm.
The accompanying Alpha Titanium Retainers are designed to significantly reduce valvetrain mass while providing the strength required for demanding performance applications. Skunk2 uses 3D CAD and FEA during development and tests its valvetrain components on both engine dynos and race vehicles.
Why Upgrade Your Honda K20 or K24 Valvetrain?
High-performance Honda K-Series engines often operate at substantially higher RPM than standard engines. As engine speed increases, controlling valve movement becomes increasingly important.
Upgrading to a properly matched set of performance valve springs and lightweight titanium retainers can improve valvetrain control and provide the supporting hardware required for many performance camshaft combinations.
The Skunk2 Alpha kit is designed for enthusiasts building high-RPM naturally aspirated, track, competition and performance street K-Series engines.

Advanced Dual Valve Spring Design
Skunk2 Alpha Valve Springs use an inner and outer spring combination with differing frequencies. The springs are mated using a slight interference fit, creating a dual-spring system designed to improve valve control and help prevent valve float at high engine speeds.
Skunk2 states that the Alpha Valve Springs are designed to maintain valvetrain stability at engine speeds exceeding 10,000 rpm, making them particularly suitable for high-RPM Honda K-Series performance builds.
Lightweight Titanium Retainers
The Alpha Titanium Retainers are designed to reduce the mass of the K-Series valvetrain.
Reducing valvetrain mass can help improve valve control at high RPM, while the retainer geometry is designed to provide additional rocker arm clearance and improved valve seal clearance.
Skunk2’s Alpha Titanium Retainers feature:
- Lightening grooves for reduced mass
- Radius-cut edges for additional rocker clearance
- Reduced overall height
- Improved valve seal clearance
- CNC-machined construction
- Certified medical-grade titanium
- Individual inspection after machining
- Individual serialization for traceability
Skunk2 states that its titanium retainers are developed using 3D CAD and FEA and validated through dyno and track testing.
Honda K20 & K24 Performance Applications
The Skunk2 344-05-1410 kit is designed for Honda K-Series performance applications, including popular K20 and K24 engine builds.
Published application information includes engines such as:
- Honda K20
- Honda K20A
- Honda K20Z
- Honda K24
- Honda K24A
- Honda K24Z
Exact compatibility can depend on the cylinder head, existing valve spring configuration, retainers, keepers and camshaft combination. Always verify your exact engine and cylinder-head specification before ordering.
Important Keeper & Retainer Compatibility
Important: When using Skunk2 Titanium Retainers on 2004 and newer engines, pre-2004 locks/keepers/cotters must be used.
Skunk2 explains that pre-2004 keepers can be identified by the absence of markings along the top edge, whereas 2004 and newer keepers feature laser-etched markings. Correct retainer and keeper selection is critical because the earlier and later keeper designs have different angle ratios.
Using incompatible retainers and/or keepers may result in serious engine damage. Verify the correct components before installation.
Important Spring Base Requirement
Skunk2 specifies that its Spring Bases, part number 312-05-0010, must be used when installing these dual springs into single-spring K-Series cylinder heads.
The same spring bases are also required when installing these springs in F20C/F22C engines.
If your K-Series cylinder head was originally designed for single valve springs, check the complete valvetrain specification and ensure the required spring bases are fitted before installation.
Ideal for High-RPM Honda K-Series Builds
The Skunk2 Alpha Valve Spring & Titanium Retainer Kit is designed for enthusiasts who want improved valvetrain control and reduced valvetrain mass in a performance Honda K-Series engine.
It is particularly suited to:
- High-RPM naturally aspirated K20 builds
- High-RPM K24 performance engines
- Honda track cars
- Fast-road performance builds
- Competition engines
- Performance camshaft upgrades
- K20/K24 engine swaps
- Built Honda K-Series cylinder heads
Performance Camshaft Compatibility
Performance camshafts can place additional demands on the engine’s valvetrain. Valve springs and retainers should therefore be selected based on the complete camshaft and cylinder-head specification.
The Skunk2 Alpha kit provides a matched dual-spring and titanium-retainer package for K-Series performance applications. Before installation, verify that the spring pressures, installed height, coil bind clearance and retainer/keeper combination are suitable for your specific camshaft and cylinder head.
Installation & Engine Building
Installation should be performed by a qualified engine builder or technician experienced with Honda K-Series cylinder heads.
Before final assembly, check:
- Installed spring height
- Seat pressure
- Open pressure
- Coil bind clearance
- Retainer-to-seal clearance
- Retainer-to-keeper compatibility
- Rocker arm clearance
- Camshaft specifications
- Valve-to-piston clearance where applicable
Always follow the manufacturer’s installation requirements and verify the complete valvetrain setup before operating the engine at high RPM.
