Valvetrain Components

Unlock your engine’s full potential with premium valvetrain components from SBX Performance. The valvetrain is the heart of your cylinder head, controlling airflow, timing, and stability at every RPM. Upgrading these parts is essential for handling high-RPM performance, turbocharging, supercharging, and aggressive cam profiles without sacrificing reliability.

Our collection includes everything you need for a complete cylinder head build:

• Valve Springs – prevent valve float and maintain stability under high RPM.

• Retainers – titanium and steel options for strength and reduced valvetrain mass.

• Rocker Arms – improve efficiency, reduce friction, and handle high-lift cams.

• Valve Guides – precision fitment for durability and oil control.

• Lost Motion Assemblies (LMA) – optimized for Honda/Acura VTEC systems.

• Valve Stem Seals – prevent oil leakage and extend engine life.

• Valve Locks & Keepers – secure retainers and valves under extreme load.

• Complete Valvetrain Kits – all-in-one solutions with matched components.

Every component we carry is CNC-machined, heat-treated, and race-proven, ensuring maximum reliability for both street builds and track machines. Whether you’re refreshing an OEM setup or pushing the limits of a fully built motor, SBX Performance has the valvetrain parts you need to rev higher, make more power, and drive with confidence.
