Description

EC Billet Titanium Retainers & Dual Valve Spring Kit for 6mm Valve Stems.


Engineered for high-RPM stability and performance, the EC Billet Titanium Retainers and Dual Valve Spring Kit is the perfect upgrade for builders running aggressive camshafts, high-ratio rockers, or oversized valves in high-output engines. This kit is designed specifically for 6mm valve stems, delivering a lightweight, high-strength valvetrain combination optimized for racing and high-performance applications.


The billet titanium retainers reduce valvetrain mass, allowing for faster revs and more stable valve control at extreme engine speeds. The dual valve springs provide progressive seat pressure to resist valve float and support high lift cams.


Important Fitment Note: Do not use dual valve springs with stock valves. We recommend 6.5mm stainless steel valves with a 6mm undercut tip for Big Block Honda clone engines or 6mm stem valves for other engine types.

FAQ

Can I use this kit with stock valves?

No. Dual valve springs should not be used with stock valves. We recommend 6.5mm stainless steel valves with 6mm tips or performance 6mm stem valves.


Do the retainers come with keepers?

Yes, this kit includes 6mm valve keepers/locks for proper valve stem fitment.


Are lash caps included?

No. Lash caps are not included and should be purchased separately if required by your cam profile or setup.


What is the advantage of titanium retainers?

Titanium retainers are significantly lighter than steel, reducing valvetrain mass and improving valve control at high RPM, especially in racing applications.
