Description

EC 5.5mm Billet Titanium Retainers for Large Diameter Dual Valve Springs


Our EC Billet Titanium Retainers are engineered specifically for 5.5mm valve stems and designed to perfectly fit larger diameter dual valve springs such as our EC 270 Dual Valve Springs and the Comp Cams GP-966-2 springs. Unlike standard retainers, these billet titanium retainers fully cover the top of the outer spring, providing superior spring control and valvetrain stability.


Crafted from high-quality titanium, these retainers offer the ideal balance of ultra-lightweight construction and exceptional strength. This combination reduces reciprocating mass, enhancing valve train stability at high RPMs—making them perfect for aggressive cam profiles and high-ratio rocker setups. The billet design ensures durability and precision fitment, delivering reliable performance under the most demanding racing conditions.


Important: Lash caps are not included. These retainers should not be used with stock valves. We strongly recommend pairing them with 5.5mm stainless steel valves designed for dual spring setups.


Valve Compatibility:

  • Fits 5.5mm valve stems
  • Designed for EC 270 Dual Valve Springs and Comp Cams GP-966-2 springs (outer spring ID .750”, inner spring ID .650”)
  • Not compatible with GP-965-1 springs

Recommended Use:

  • Ideal for use with EC Big Valve 14cc Heads or similar equipped with 5.5mm valves
  • Valves sold separately

Package Includes:

  • EC 5.5mm Billet Titanium Retainers
  • 5.5mm Valve Keepers/Locks

Upgrade your valvetrain with these premium billet titanium retainers for maximum durability, reduced weight, and enhanced performance on large-diameter dual spring setups.

FAQ

Q1: Will these retainers fit stock valves?
A1: No, these retainers are designed for use with 5.5mm stainless steel valves, not stock valves. Using them with stock valves may cause improper fitment and performance issues.

Q2: Which valve springs are compatible with these retainers?
A2: These retainers fit large diameter dual valve springs such as EC 270 Dual Valve Springs and Comp Cams GP-966-2 springs (outer spring ID .750”, inner spring ID .650”). They are not compatible with Comp Cams GP-965-1 springs.

Q3: Are lash caps included with this kit?
A3: No, lash caps are not included and must be purchased separately if required for your valve train setup.

Q4: Can these retainers be used with other cylinder heads?
A4: They are recommended for use with EC Big Valve 14cc Heads using 5.5mm valves, but may fit other heads designed for 5.5mm valve stems with compatible dual spring setups.

Q5: What are the benefits of using titanium retainers?
A5: Titanium retainers are significantly lighter than steel or aluminum, reducing valve train mass and inertia. This improves valve train stability at high RPMs, reduces wear, and allows more aggressive cam profiles and higher engine speeds.

Q6: Do these retainers improve engine performance?
A6: While retainers themselves don’t directly increase horsepower, their lightweight and durable design allows the engine to safely operate at higher RPMs and aggressive cam profiles, potentially unlocking more power from your setup.
