Hardy Spicer is a brand of automotive transmission or driveline equipment best known for its mechanical constant velocity universal joint originally manufactured in Britain by Hardy employing patents belonging to US-based Spicer Manufacturing. Hardy and Spicer soon became partners. Later Spicer became Dana Holding Corporation.
Since the commercial success of front wheel drive cars began in the 1960s the industry manufacturing universal joints has grown enormously.
The Hardy Spicer and Laycock Engineering group of businesses, later known as Birfield, have been part of the GKN Driveline group since 1966.
