These brand-new, genuine Girling slave cylinders were original equipment on many formula cars and sports racers equipped with Hewland transaxles from the 1960s to the 1980s. We offer two styles in two different bore sizes. Both designs are for bolt-on installations. Note that the left-hand and right-hand versions are not mirror images (see photo).

The .75" bore size, which is not very common, is available in a Right-Hand version only. This unit was original equipment on the Ford Escort "Mexico".

The more common .87" bore is available in either a right- or left-hand version. Choose the style which allows clutch bleeding without removal of the cylinder, or the most direct inlet hose routing. The inlet and bleeder ports are interchangeable.
The .87" Right-Hand version is typically installed on the left side of the transaxle in mid-engined cars. It is most commonly used on the Hewland Mk-series and FT 200 gearboxes.
The .87" Left-Hand version is ideal for mounting on the right side of the transaxle in mid-engined cars. It is used on the Hewland FG 400 gearbox.

All versions have two 5/16" (8mm) mounting bolt holes oriented perpendicular to the bore and spaced 2 3/8" center-to-center. Overall length approximately 3 1/2" including boot. Inlet and bleeder ports are both threaded 3/8-24 UNF (3AN) with a concave seat. Both bore sizes have a 1.25" stroke. Pushrod not included.
