This Shurflo by Pentair Pumphead Kit fits the 4258 series High Flow System. It also fits the 4648 series Pro BaitMaster II 4.0 heavy duty livewell and washdown pumps.
It’s a genuine OEM part, giving a full pumphead rebuild rather than needing to source individual valve and diaphragm components separately. Check the exact model number against the compatibility list before ordering.
A worn pumphead is a common reason for reduced flow or pressure on an otherwise functional BaitMaster II system. This kit addresses that directly. Check out the rest of our pump parts and accessories.
