Manual or power-assisted applications both work with this 1.00 in. bore tandem aluminum master cylinder, mounting to the common 3.22-3.40 in. flange pattern used on most domestic cars and trucks since the mid-1960s.

Tandem Aluminum Master Cylinder Features:

• Dual fluid outlet ports on both sides of the bore.
• 1.10 in. stroke with a 2:1 volume ratio between the primary and secondary chambers.
• High-pressure die-cast body weighs only 3 lb., 75% lighter than most cast iron OE master cylinders.
• No pushrod included, for manual applications without a boost pushrod installed.
• Pairs with Wilwood's 260-13190 combination proportioning valve kit for a complete brackets-and-lines setup.
