Here is something that will prove to be one of the most valuable tools in your trailer if you are running a BAE fathead 5 and a screw blower. Due to the motors high rpm levels it has a tendency to pick on the valve springs and wear them rapidly or even worse break them. This will usually happen at the most inopportune moment. These tools will allow you to remove the intake or exhaust valve spring between rounds and not miss a beat on race day. The intake and the exhaust spring remover are sold separate so please specify which one you want when ordering. These are made from durable steel and use precision bearings with a cnc machined spring cup to make this a durable tool. Tool can also be ordered for fathed 6's.
