MK Series kits include the adapter, cylinder, release bearing for stock or 7-1/4" racing clutch, attaching screws, and line adapters. Hose ends and remote bleed kit must be ordered separately. Size of pressure line (-3 or -4) must be specified so that we can install the correct fitting in the cylinder. NOTE: This system is attached to the MK transmission with three bolts which thread into three holes encircling the main input shaft seal. If these three holes are missing in your case, a Custom annular slave cylinder system must be ordered.
