GSC Power Division

The camshafts and valvetrain decide how an engine breathes and how high it can rev. GSC Power Division makes camshafts, valves, valve springs and retainers for tuners and engine builders who want more power and a valvetrain that can keep up. Here you’ll find parts for popular turbo and sports engines.

American valvetrain for turbo and sports engines

GSC Power Division is an American brand focused on valvetrain parts and camshafts. The brand is particularly well known among owners of Japanese performance cars such as the Mitsubishi Evo, Subaru and Toyota, but the range also covers other popular engines. GSC treats the valvetrain as a whole: camshaft, valves, springs and retainers need to work together so the engine gets the desired character while running reliably at high rpm and high boost.

GSC Power Division’s key products

Camshafts come in several profiles, from mild street cams that suit a stock turbo to more aggressive profiles for large turbos and high rpm. Valve springs and retainers, including titanium retainers, match the lift of the camshafts and make sure the valves close correctly. GSC also makes valves in various materials and sizes, as well as valve guides and other cylinder head parts. Many parts are sold as kits so they work together from the start. See each product for engine fitment.

Frequently asked questions

Do I need new valve springs when fitting new camshafts?

Often yes, especially if the camshafts have more lift or will run at higher rpm than stock. The springs must suit the cam profile so the valves keep up. See the recommendation for each camshaft.

How do I choose the right cam profile?

It depends on your turbo, your fuel and how the car is used. A milder profile gives good pull from low rpm, while a more aggressive profile moves the power higher up the rev range. Feel free to contact us with details of your setup.
