Holden Salisbury differential

The Holden Salisbury Differential is an automobile axle manufactured by Holden at its Melbourne plant, alongside the weaker Holden Banjo Differential, introduced in 1948, installed in Holden's debut model, the Holden 48-215, all the way through until production of the VL Commodore ceased in 1988. The Salisbury assembly is similar to that or your average passenger car, the Banjo on the other hand shared an assembly similar to that of the Ford 9-inch axle.

The Differential was not named after the Adelaide suburb of Salisbury, South Australia, rather it gets its name from The Salisbury Wheel Company which was founded in the USA in 1901. In 1905, the company started manufacturing front axles and two years later rear axles were added to its product line. It was acquired by Spicer in 1919 and in 1970 the Salisbury Axle group was renamed the Spicer Axle Division, though the style of housing continued to be referred to as the Salisbury type.

The Holden Salisbury type diff began to be phased out with the introduction of the VL Commodore, replaced by the BorgWarner BW78 colloquially known as the 8-bolt diff due to the 8 bolts holding the diff cover on.
