Premium quality Alfaholics production. This shaft has been designed to fit the new high quality reproduction 105 GTV high capacity oil pumps that we stock. By using this shaft, any engine can be converted easily to run the GTA twin plug distributor. It is also ideal for use on racing GTAs, since it allows a GTV sump to be used in conjunction with the high capacity GTV oil pump. Not only does this mean increased oil flow due to the longer gear pump, but it also results in increased ground clearance, since GTV sumps are shallower than GTA magnesium ones. This permits running a lower ride height, whilst still conforming to the 100mm FIA ground clearance regulation and also prevents damaging deep magnesium sumps.
