Cross Driver for PSI Rev Limiter

PSI doesn't make their fantastic little mechanical rev limiters or the drivers for them anymore. But there are still a bunch of the units out there in use. They work great and lack of the proper driver is a terrible reason to NOT be able to use one on your Super-Mag setup. So...we make these in-house to satisfy the demand. Includes a nylock nut, woodruff key and stainless washer. If you need your PSI rev limiter serviced, calibrated or reset to a different RPM, we can do that for you!
