MSD Non-Magnetic Pick-Ups are engineered for extreme applications. In fact, this Pick-Up was designed and tested on 300+ mph top fuel dragsters! To live up to MSD demanding expectations in these extreme applications, MSD's took it upon ourselves to design and build the Pick-Ups in-house. This way MSD's can control every aspect of their assembly and quality. Each Pick-Up is hand wound on a special bobbin and terminated to the tinned conductor, Teflon jacketed wiring. These wires are also routed through a strain relief for protection. This assembly is then installed into the precision housing and is potted with a fracture resistant epoxy compound. To ensure that the windings are entirely encased in epoxy, the Pick-Ups undergo a vacuum procedure to remove any air inside the housing. All of these procedures are necessary to produce the strongest, most reliable non
