AccuAir Suspension 70 amp power supply kits include a 25 ft. of 6 AWG wire, a weather-proof fuse holder, 70 amp fuse, and 90 amp solenoid. The sealed Maxi-Fuse holder provides smart circuit protection and a simple way to disable the entire system for maintenance. The heavy-duty 90 amp dual-contact style relay is more than capable of operating two Viair compressors of your choice. And the power wire includes copper lug terminals and shrink tubing. These power supply components are ideal for running power to your single or dual compressor air management system.
