About this item

Need to totally kill power to your ride? This 4-post master battery disconnect switch is your go-to. It's a super straightforward install – no crazy tools needed. Just wire it up and you’ve got a reliable way to cut all battery power. Great for security, storage, or when you’re working on the electrical system. It handles up to 200A and works on both 12V and 24V systems. The whole kit is metal and built tough to resist corrosion, so it’ll last even in harsh under-hood conditions. It’s a direct replacement for those DPST kill switches used in NASCAR and NHRA, but double-check your part numbers (like 51-904) to make sure it fits. Super handy for preventing battery drain or accidental shorts. Pro tip: if you’re not super confident with wiring, maybe get a mechanic to help install it. Comes with all the hardware you need!
