Keith Black (KB) Performance Pistons Overview

KB Performance Pistons is a product of United Engine and Machine Company which was started in 1922 in Fresno, California. For eight years, the company continued to grow and build a reputation for the manufacturing of pistons. Then in 1930 the company was moved to San Leandro, California in order to supply OEM manufacturers located on the West Coast. During the war, the company started supplying special marine applications for PT boats and some small munitions, such as incendiary bombs. Following the war, the company continued to grow with its strength built on flexible management and its ability to design and build its own equipment at considerable savings. This philosophy carried the company through the 50's, 60's and 70's. In the late seventies the company relocated to Carson City, Nevada, where it has continued to grow. Since its move, United Engine has continued to look at its role in the domestic and world market. Currently, UEM manufactures the Silv-O-Lite OE aftermarket piston line, KB Performance Pistons (including the motorcycle division), and The Claimer Performance Piston Series.
