Drop the old mechanical-switch, cheap battery disconnect for solid-state technology. The Modern Racing's Solid-State Battery Disconnect Master Kit is designed specifically for motorsports applications. This weatherproof 6061-billet case is designed to withstand harsh environments at only one-third the weight of a traditional switch.

Unlike the traditional mechanical switch, our system can be triggered in multiple ways, such as a driver’s switch, exterior/track crew switch, and any ground input like a fire-suppression sensor (switches included in the master kit). This ads three layers of safety, all without complicated, unreliable wiring or the need for a long metal push rod in the car. Accepted for competitive use in the NHRA Pro Stock and E3 Spark Plugs Pro Mod series.
