Description

EC Billet Aluminum Retainers for 5.5mm Valve Stems – Compatible with EC Beehive Valve Springs


Upgrade your valvetrain with our EC Billet Aluminum Retainers, precision-engineered to fit 5.5mm valve stems and specifically designed for use with EC Beehive Valve Springs. These retainers are CNC-machined from high-strength aluminum to reduce valvetrain weight, enhance high-RPM stability, and withstand the rigors of competitive racing.


Each retainer is hard anodized in a vibrant red finish, offering superior wear protection, chemical resistance, and that signature EC Racing look when you remove the valve cover.


Important Compatibility Note:

These retainers are only compatible with EC Beehive Springs. Beehive springs have a taller installed height than traditional small-block clone valve springs and are not interchangeable with stock or standard aftermarket single springs. These are intended for high-performance billet heads, and are commonly used in big block clones and V-Twin engine builds.

FAQ

Q1: Will these retainers fit stock valve springs?

A: No. These retainers are only compatible with EC Beehive Valve Springs. They will not fit standard single or dual valve springs due to the different installed height and taper.


Q2: What size valve stem do these retainers support?

A: These retainers are designed for 5.5mm valve stems, which are commonly found in Honda GX200, Predator 212 Hemi, and most clone 196 engines. Always verify your valve stem size before purchasing.


Q3: Can I use these retainers on my Predator 212 Non-Hemi or Wildcat engine?

A: No. These engines typically use 5mm valve stems, which are not compatible with this 5.5mm retainer kit. You’ll need the 5mm version of our EC billet retainers.


Q4: What makes these retainers ideal for high-RPM racing applications?

A: The billet aluminum design reduces valvetrain weight, and the hard anodized coating enhances strength and wear resistance—resulting in improved RPM stability and longer part life.


Q5: Are valve springs included with this kit?

A: No. This listing includes only the billet retainers and 5.5mm valve keepers/locks. EC Beehive Valve Springs are sold separately.


Q6: What type of engine builds are these retainers best suited for?

A: These retainers are ideal for high-performance racing engines using EC billet heads, big block clones, or V-Twin applications where beehive springs are required.
