In 1964, armed with a tremendous wealth of knowledge and a single cam-grinding machine, Sig Erson Racing Camshafts was born. The goal: To produce the best possible camshafts for all types of racing. The first Erson facility was a small 1600 square foot truck repair shop in Hawthorne, California. Meager beginnings for what Erson Cams was to become.

With no budget for advertising or even state of the art machinery (lobe models and masters were often hand ground) Sig Erson Racing Camshafts quickly gained a huge following in both racing and the burgeoning hot rod scene of the 60's and 70's. It was simple, if you wanted a engine that made incredible power yet was easy on valve train parts, an Erson Cam was your only choice.

Sig Erson Racing Camshafts quickly out grew the Hawthorne Facility and moved, in 1967 to a 4000 sq ft facility in Long Beach, California. In 1969, Mr. Erson and his crew of 10 full time cam grinders, moved yet again to a 10,000 sq ft building. At the time it was the largest facility in the country dedicated to state of the art camshaft development and grinding. In 1981 Super Shops Inc purchased Sig Erson Racing Camshafts. The name was changed to Erson Cams and the company was relocated to Carson City, Nevada.

1997 marked the beginnings of dark times with Super Shops Inc. going bankrupt. Erson Cams and its sister company  Mallory Electric, were purchased by a succession of owners: Echlin, Dana and finally Mr. Gasket. Despite the lack of ownership support, Erson Cams persevered, continuing to develop new product lines such as the FSP Valve Springs, FE Ford, Chrysler Shaft Mount Billet Rocker Arms and continued the development of camshafts.

In 2006 Erson Cams was purchased by Engine Parts Warehouse, Inc./PBM Performance Products of Louisville, KY. With the merger of Erson Cams and PBM Performance Products a complete line of valve train and related components was developed. This new product line offers state of the art valve train systems to complete race and performance engine packages.
