Description

EC Billet Aluminum Retainer Kit with 26lb 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 26lb 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 .275"

This kit is optimized for aggressive camshafts like our Banzai, Reaper, and other .265" to .275" lift racing cams. The 26lb valve springs provide the pressure needed to maintain proper valve operation at high RPMs without risking valve float or loss of performance.


Kit Includes:

  • (2) EC Billet Aluminum Retainers – Red Hard Anodized
  • (2) 26lb Single Valve Springs
  • (2) 5mm Valve Keepers/Locks

FAQ

Q1: Will this kit fit my Predator 212 engine?

A: Yes, if you have a Predator 212 Non-Hemi engine. This kit is not compatible with the Hemi version, which uses 5.5mm valve stems.


Q2: Can I use this kit with a dual spring setup?

A: No. This billet retainer kit is designed for single valve springs only (stock, 22lb, or 26lb). It is not compatible with dual spring configurations.


Q3: What camshafts is this kit best suited for?

A: It’s ideal for camshafts up to .275” lift, including EC's Banzai, Reaper, and other .265 performance cams.


Q4: How do I know if my valves are 5mm or 5.5mm?

A: Most engines like the Predator Non-Hemi, Tillotson 212R/225R, Wildcat 223/240, and Ghost 212 use 5mm valves. Engines such as the Honda GX200 and Predator 212 Hemi typically use 5.5mm valves. Always verify your valve stem diameter before ordering.


Q5: Are the valve springs included in this kit?

A: Yes, the kit includes two 26lb single valve springs, along with retainers and 5mm keepers/locks.


Q6: What are the benefits of billet aluminum retainers?

A: They are lighter than steel retainers, reducing reciprocating mass, which helps increase valvetrain stability, reduce valve float, and improve RPM performance. Plus, the hard anodized finish offers enhanced durability and a clean, professional look.
