Wiseco

Wiseco is an engine-internals brand, and this page lists mostly piston ring compressor sleeves, with a piston kit alongside. They are engine assembly tools, not compressors for air.

A ring compressor sleeve squeezes the rings on a piston so it can slide into the cylinder bore during an engine build or rebuild. The titles give the sleeve's bore size in millimetres and the finish, black anodized. The sleeve must match the bore of the cylinder you are building, so measure the bore before ordering rather than choosing by engine name.

There is no vehicle list for this brand. The piston kit in the range is written by engine family in its title, so read the application line carefully and match it to your engine. Each product page lists the engine or vehicle it fits where applicable.

For an engine build, a sleeve is a tool you buy once for each bore size, while a piston kit is a set of parts that goes into the engine. Check bore size, compression and dome style before ordering a piston kit, because these change how the engine runs and are not interchangeable between builds.

If the part you want is not here, use the vehicle selector to see only parts for your vehicle.
