Valvetrain

Every little detail counts when it comes to building your engine and the overall performance of it, an excellent way to squeeze some extra power out of your engine is through the valvetrain components. The valvetrain plays an integral part when building your engine as it controls the operation of the intake and exhaust valves in an internal combustion engine. The key to choosing the right valvetrain components is to match the parts to the application.

The main Valvetrain components are Lifters, Rocker Arms, Camshafts, Pushrods, Valves and Valve Springs. With this in mind, we have a wide range of high end performance parts to suit your application.

Valve train components are often replaced when rebuilding stock engines, worn rocker arms and lifters should not be reused to prevent failures later on.

If you are modifying the engine to make more power or turn higher RPMs, or it is being purpose built for racing, stock parts usually won’t be sufficient. You want maximum valvetrain rigidity and stability for peak RPM power!

Whatever your needs are, check out our selection of lifters, camshafts, pushrods and more at RaceMAX Direct. If you’re interested in finding out more about the valvetrain process or need some advice on selecting high quality parts, call 02 9791 5030 or enquire with us online and we’ll get back to you right away.
