This is the correctly manufactured Clutch Slave Cylinder with the slotted internal bleed hole for MGA MGB. For years the aftermarket companies have reduced cost by changing the internal flow of the MGA and MGB clutch slave cylinders. This causes a large amount of headaches when trying to bleed the slave cylinder, the air is unable to easily escape. With this OE designed cylinder it has the correct slotted bleed hole and the correct support for the mounting base which gives the cylinder stability. We have also gone one step further, to keep stability in the rubber cup we had the seal support made out of an alloy for longer life and stability. Cross Reference GSY106, LL13901
