Description

EC Billet Aluminum Retainer Kit with 22lb Valve Springs – Fits 5mm Valve Stems


Upgrade your valvetrain with the EC Billet Aluminum Retainer Kit engineered specifically for small engines using 5mm valve stems. This performance kit includes our lightweight billet retainers, hard anodized in a bold red finish for both durability and visual impact, along with matched 22lb single valve springs and 5mm keepers/locks.


Precision-machined from high-strength aluminum, these retainers significantly reduce valvetrain weight, improving RPM stability, valve control, and long-term reliability in high-performance racing applications. The hard anodized coating adds chemical resistance and wear protection—ideal for demanding builds.


Designed for High-Lift Cams Up to .265"

This kit is optimized for camshafts like our Ghostbuster, Mod2, and other racing cams up to .265”. The 22lb valve springs provide the pressure needed to maintain proper valve operation at high RPMs without risking valve float or loss of performance.

  • (2) EC Billet Aluminum Retainers – Red Hard Anodized

  • (2) 5mm Valve Keepers/Locks

FAQ

Q1: Which engines will this retainer kit fit?

A: It's designed for engines using 5mm valve stems, such as Predator 212 Non-Hemi, Tillotson 212R/225R/225RS, Wildcat 223/240, Ducar 212, Tillotson 212E, and Ghost 212. Hybrid 5.5mm valve engines, such as the Ducar 212E and Ghost 212, may also use the kit since they accept 5mm keepers/locks.


Q2: Can I use this kit on a Predator 212 Hemi or GX200 engine?

A: No. The kit will not work with engines that use 5.5 mm valve stems, including the Predator 212 Hemi and Honda GX200/Clone 196.


Q3: What camshaft lifts are these springs suitable for?

A: These 22-lb valve springs are optimized for camshafts with lift to .265", such as EC's Ghostbuster, Mod2, and other high-lift racing camshafts.


Q4: Does this kit support dual valve springs?

A: No. It is only compatible with single valve spring setups—stock, 22-lb, or 26-lb springs. Dual spring configurations are not supported.


Q5: What are the benefits of using EC billet retainers?

A: EC billet retainers are lightweight and reduce valvetrain mass, help improve RPM performance, offer enhanced valve control, and feature a robust,hard-anodized, wear-resistant finish for racing durability.


Q6: What's included in the kit?

A: The kit comes with:

  • Two EC billet aluminum retainers (red, hard anodized)
  • Two 22-lb single valve springs
  • Two 5 mm valve keepers/locks


Q7: Is special hardware required for installation?

A: No. This kit utilizes standard 5 mm split-style valve keepers and locks and installs just like stock retainers, using standard valve spring compressor tools.
