Supertech

When an engine is going to rev higher, run more boost or be built from the ground up, the valvetrain is one of the places where quality matters most. Supertech makes valves, valve springs, retainers, valve guides and pistons for engine builders and tuners. Here you’ll find parts for both powerful street cars and dedicated competition engines.

Engine parts for demanding builds

Supertech is an American brand specialising in internal engine parts, particularly for the valvetrain. The brand is well known among engine builders working on popular Japanese and European engines as well as American V8s, and the parts are used in everything from mildly tuned street cars to high-output turbo engines. The focus is on materials and fit that cope with high rpm, high temperatures and high boost, so the engine can run reliably even when pushed hard.

Supertech’s key products

Valves are the core of the range and are available in several materials and oversizes, including exhaust valves designed for the high temperatures in turbo engines. Valve springs and retainers, including titanium retainers, keep the valves following the camshaft at high rpm. Supertech also makes valve guides, valve seats, keepers and seals, as well as forged pistons for many engines. The parts can often be bought as kits for a complete cylinder head. See each product for engine fitment.

Frequently asked questions

When should I upgrade my valve springs?

It is a good idea when you fit camshafts with more lift, raise the rev limit or run higher boost. Stronger springs help the valves follow the camshaft so you avoid valve float. Choose springs that match your camshaft.

Why use special exhaust valves in a turbo engine?

The exhaust valves in a turbo engine are exposed to very high temperatures. Valves made from heat-resistant materials keep their shape and seal better under that load. See the material in the description of each product.
