About Wiseco-

Wiseco was founded in 1940 by Clyde Wiseman in Cleveland, Ohio. The company initially focused on producing high-performance pistons for marine racing, but it faced early challenges. Despite this, Wiseco's reputation for quality grew quickly within the motorsports community, and by 1941, the company began officially manufacturing pistons for automotive and motorcycle enthusiasts.

Wiseco's early success was driven by its focus on precision engineering, with the company using an innovative forging process to create pistons that were more durable and stronger than those made using traditional casting methods. This process contributed to Wiseco's reputation as a high-performance parts manufacturer.

The company expanded over the years into new markets, including snowmobiles, motorcycles, and ATVs. Their pistons gained popularity in racing, especially in series like NHRA (National Hot Rod Association) and NASCAR, where they were known for their reliability and performance under extreme conditions.

Throughout the 1950s and 1960s, Wiseco continued to grow its product offerings and expand its operations. In 1964, Wiseco moved to a larger facility to meet the increasing demand for its products. The company also began to develop and refine its piston designs for a wider variety of engines and racing applications, solidifying its place in the aftermarket parts industry.

In the 1970s, Wiseco further diversified its product line, manufacturing pistons for a range of off-road vehicles, motorcycles, and snowmobiles. The company's expansion into these new segments helped establish Wiseco as a trusted name in motorsports and performance enthusiasts' circles.

By the 1980s and 1990s, Wiseco had become one of the top manufacturers of aftermarket pistons, thanks to its cutting-edge technology, quality control, and commitment to performance. Wiseco’s pistons were used by racers and enthusiasts in virtually every motorsport discipline, from motocross to drag racing, to road racing.

Today, Wiseco continues to be a leader in the high-performance piston and engine parts industry. The company has expanded its offerings to include various engine components, like connecting rods, crankshafts, and complete engine kits, for a wide range of motorsports applications. Their products are used by professionals and hobbyists alike in the automotive, motorcycle, powersports, and racing industries, and the company remains a key player in aftermarket performance parts.

Wiseco's legacy is built on a foundation of innovation, performance, and quality, and it remains dedicated to pushing the boundaries of engineering excellence for high-performance engines.
