Pro Valve Racing Products
The Pro Valve Racing Products collection at Prime Speedworks is focused on high-performance valvetrain components for serious street, race and motorsport engine builds. Pro Valve Racing Products manufactures competition-grade valves, racing valve springs, titanium retainers, valve locks, valve seals and related cylinder head components for performance engine platforms. The brand promotes a “system” approach to valve spring kits, where the spring, retainer and supporting hardware are designed to work together rather than treated as separate parts.
Prime Speedworks’ Pro Valve range includes competition series valves and valvetrain components, with current listings including Toyota Supra 2JZ-GTE +1mm Competition Series intake valves. Prime Speedworks also positions Pro Valve as a specialist manufacturer founded in 2016 by Rafael Lebron, with more than two decades of cylinder head and valvetrain development experience behind the brand.
In any serious engine build, the valvetrain has a hard job. It needs to control valve motion at RPM, manage spring pressure, support camshaft profile, handle boost or naturally aspirated airflow demand, and maintain reliability under heat and repeated load. Poor valve control can cost power, create instability, damage components and limit how hard the engine can be pushed.
Pro Valve Racing Products suits engine builders who are paying attention to the full cylinder head package — valve material, valve size, spring pressure, installed height, retainer selection, lock compatibility, guide condition and the way the engine will actually be used. This matters across high-boost turbo engines, high-RPM naturally aspirated builds, nitrous combinations and motorsport applications where reliability is just as important as airflow.
Prime Speedworks supports Pro Valve Racing Products with a practical, technical approach. We understand that valvetrain selection needs to suit the engine platform, camshaft, RPM target, boost level, cylinder head work, intended fuel, and racing environment. Whether it is a 2JZ, LS, Honda, Nissan, rotary support build, powersports application or custom cylinder head package, the right valvetrain parts can make the difference between a strong engine and one that is always on the edge.

Why buy this collection from Prime Speedworks
Valvetrain parts are not just small cylinder head components — they control how the engine breathes, how safely it operates at RPM, and how reliably it survives under load. The wrong valve spring, retainer, lock or valve choice can create instability, reduce power, limit RPM or cause serious engine damage.
Prime Speedworks supplies Pro Valve Racing Products with a technical, application-first mindset. We look at the full combination, including camshaft profile, RPM range, boost pressure, cylinder head flow, valve size, spring pressure, installed height and intended use.
For Australian engine builders, workshops, racers and serious street car owners, this means access to Pro Valve components with support around proper selection. Whether the build is a tough street turbo engine, a high-RPM naturally aspirated package, a 2JZ drag setup, an LS race engine or a workshop-built cylinder head package, Prime Speedworks can help match the right Pro Valve Racing Products to the application.
This is valvetrain hardware for engines that are expected to make power, hold RPM and come back for another pass.
