Quickcar Plastic MDS With Removable Key 55-003

This QuickCar Battery Master Disconnect Switch is the lowest priced battery switch they offer. Most racing organizations and sanctioning bodies require these for an emergency cut-off switch. The plastic casing makes it the lightest master disconnect carried by QuickCar; and with the capability to run on 350 continual amps @ 12V, it is still ideal for most racing applications. It features a red removable key and is designed for 3/8" ring terminals.

    Looks very well made. I wish it had standard nuts on it but no big deal just add a 17mm wrench to truck tool box. I gave it 4 stars only cause we hadnt tested it out at the track yet. We will be buying from Quickcar again an soon
