Wiseco

Building an engine for more power, higher boost or nitrous? Wiseco makes forged pistons and related engine parts for cars, motorcycles and other vehicles where the engine has to handle more than stock. Here you’ll find forged pistons, piston rings, wrist pins and gasket kits for many popular engines.

American specialist in forged pistons

Wiseco is an American brand best known for forged pistons. The brand has a strong position in both motorcycles and powersports and automotive engines, and its pistons are used in everything from turbocharged street cars to dedicated competition engines. Forged pistons are denser and stronger than cast pistons, which makes them a natural choice when an engine is built for higher cylinder pressures and temperatures.

Wiseco’s key products

Forged pistons are the core of the range and are available for many popular engines in several bore sizes and compression ratios. Most pistons come with matching piston rings and wrist pins, so the set works together from the start. Wiseco also offers gasket kits and other parts used in an engine rebuild or conversion. See each product for engine, bore and compression ratio fitment.

Frequently asked questions

When do I need forged pistons?

When the engine will run significantly more power than stock, for example with a turbo, supercharger or nitrous. Forged pistons handle higher pressures and temperatures than most original cast pistons.

Why do forged pistons often need more piston-to-wall clearance?

Forged aluminium typically expands more when heated than cast. The cylinder therefore often needs to be machined to a slightly larger clearance. Always follow the recommended specifications for the specific piston.
