UPDATE: Be sure to check out our NEWEST Installer Series kit additions. We now offer kits with Electronic Lockout Module (E.L.M) and pressure switch options.

It’s time to drop the bulky old mechanical-switch for good! The three biggest complaints we receive when discussing mechanical battery disconnects are:

1.) The units are primitive and bulky

2.) Fabrication is normally needed

3.) There are no simple and clean options to allow a driver-controlled unit

We at Modern Racing have successfully resolved these issues with our electronic battery disconnect. Our disconnect eliminates the need for a mechanical rod, giving you a much smaller overall footprint than mechanical units. It also requires no fabrication in basic applications, needing just a flat surface for mounting. Our system can be triggered with a simple flip or bump of a switch and allows customers to mount multiple switches where they see fit. With this, you now have a way to add an extra layer of safety easily within the grasp of both the driver and crew members.

Designed to work in the harsh environment of motorsports, Modern Racing has rigorously tested this unit in many different race car applications including electrically-hungry blower ProMods (Which see an average of 400A surge at start-up). This unit is rated at a stout 750A at 10 seconds (With 900A surge and 250A continuous), enough to handle most anything you can throw at it. Throw your mechanical cut-off in the trash, because once you set-up one of Modern Racing’s disconnects, you’ll never go back!

This battery disconnect switches are sold individually, as well as in a MR Installer Series Kits. With four different variations of kits, you're sure to find the kit that meets your needs! The MR Installer Series Kits provide you with nearly everything you need for a clean and easy battery disconnect install! Our goal with the kits is to provide a system that is as close to plug-and-play as possible, while still allowing for a completely custom design. Combine this with one of our MR Builder Series Pro Battery Cable Kits and you'll have everything you need to set-up your wiring from the battery to your ignition.
