Wiseco Piston Kit

Wiseco Piston Kit Wiseco's been keeping up the pressure since 1941. Cylinder pressure, that is, by manufacturing and selling high-quality pistons and other precision core engine parts. Clyde Wiseman began making pistons in his garage for himself and some fellow riders, and did it so well that Wiseco became and remains an instantly recognizable brand name the world over.

Here's some company piston-ology: Wiseco forges their pistons, as opposed to regular casting or hypereutectic (added silicon) casting. Among other materials, they use high silicon SAE 4032 extruded bar stock and run it through a 2000-ton press to form the pistons. This is for normally-aspirated engines. For more extreme applications such as racing, a 2618 alloy (containing copper and magnesium and capable of taking high heat/stress) is shoved through the same press.

After press forming, the pistons are carefully heat-treated and finished. According to Wiseco, this combination of forging and finishing gives their pistons more strength with lighter weight than competitor's pistons as well as minimal variance -- or, in other words, excellent quality control.

Whether you own a two-stroke, four-stroke, or fully-blown stroker, Wiseco has a piston kit for you. The kits come with a piston(s) ranging from stock diameter to almost any oversize your cylinder walls can handle, including all associated compression/oil rings, wrist-pins, and keepers.

Now that you've spruced up your ride, keep it protected with an indoor/outdoor bike cover.
