## Description

The AP Racing master cylinder with an effective hydraulic diameter of 22.4 mm, part number CP6467-224PRME:S, uses a central valve for competition applications with ABS and high-pressure circuits. Its trunnion mounting on needle bearings allows it to be integrated into a compatible pedal support.
The :S version features a sleeve in place of the anti-knockback device. The effective diameter of 22.4 mm is used for hydraulic sizing; it does not correspond to the physical bore of 25.4 mm.
The forged aluminum body and tension-loaded design limit lateral forces on the piston. The low-profile connections allow for a compact installation.
