The Rennline 6 Pole Cut Off Switch is the same style used in the factory Porsche Cup Cars. It has been designed to eliminate the possibility of the alternator circuit being damaged due to a heavy voltage surge that can occur with the use of a heavy duty single circuit On/Off Switch. When turned to the off position the engine will be automatically stopped due to the secondary switch function whereby the ignition is cut. This prevents engine 'run on' and is a vital safety factor especially in competition use. This switch is also a very simple and effective anti theft device for cars, trucks, boats and Ag, vehicles.

The new Element Fire Extinguishers are hot. Not only are they extremely lightweight and compact, but they are also highly effective. The only problem - there are no vehicle specific mounting options… until now. Rennline has developed an adapter that allows the Element to be mounted to our popular billet roll cage clamps. Fully CNC machined and anodized, these brackets and clamp come with all necessary hardware for a quick and easy installation. Includes two billet roll cage clamps, two billet Element Extinguisher Clamps, and one E50 Element Fire Extinguisher along with all necessary hardware.
