Description

EC Billet Aluminum Valve Spring Retainers for 6mm Valve Stems – For Beehive Springs


Upgrade your valvetrain with EC’s Billet Aluminum Retainers, engineered specifically for 6mm valve stems and optimized to work with EC Beehive Valve Springs. These high-performance retainers offer the ideal combination of lightweight strength, durability, and precision fitment—critical for maintaining valvetrain stability at high RPMs.

Manufactured from aircraft-grade aluminum, these retainers are hard anodized for exceptional wear and corrosion resistance. The bold red finish delivers a race-ready appearance and adds visual appeal when the valve cover is removed.


Important Compatibility Notice
These billet retainers are only compatible with EC’s proprietary Beehive Valve Springs. They are not designed to work with stock springs or standard clone-style small-block cylinder heads. Beehive springs require a taller install height, typically used in high-performance builds such as V-Twin and Big Block clone engines.


Key Features:

  • For 6mm Valve Stems – Common in Briggs Model 28/31/33 OHV, Vanguard, Intek V-Twin, and EC GX390 Stainless Valves
  • Lightweight Billet Aluminum – Reduces valvetrain mass for higher RPM potential
  • Hard Anodized Red Finish – Durable, chemical-resistant coating with a striking high-performance look
  • Precision Fitment – Designed exclusively for EC Beehive Valve Springs (springs not included)
  • Includes 6mm Keepers/Locks – Secure and reliable valve retention under high loads

FAQ

Q1: Will these retainers fit stock clone valve springs or retainers?

A: No. These retainers are specifically designed to work only with EC’s Beehive Valve Springs. They are not compatible with standard or stock-style valve springs used in small-block clone engines.


Q2: How do I know if I have 6mm valve stems?

A: You’ll need to measure the diameter of the valve stem at the top where the retainer sits. If it's 6mm (approx. 0.236"), these retainers will fit. Engines like the Briggs Model 28/31/33 OHV, Vanguard V-Twin, and EC GX390 valves typically use 6mm stems.


Q3: Can I use these in a Predator 212 or Honda GX200 head?

A: Only if you’ve upgraded to 6mm valves and are using EC Beehive Valve Springs but not recommended. These retainers are not compatible with stock 5mm or 5.5mm valve stems or stock valve springs.


Q4: What’s the advantage of billet aluminum retainers?

A: Aluminum retainers are significantly lighter than steel, reducing valvetrain mass. This improves engine response, raises the RPM limit before valve float, and reduces wear on the valve stem tips and keepers.


Q5: Are the 6mm keepers included?

A: Yes. Each order includes a pair of billet retainers along with 6mm valve keepers/locks for secure installation.


Q6: Do I need to check spring install height?

A: Yes. Beehive springs typically require a taller install height than stock. Always verify your installed height, coil bind, and clearance to ensure proper fitment and performance.
