Banks Power Dual Heater Upgrade Kit PN. 42830 Includes 750-watt high-performance coil heater, copper washer, and cable. Add the Banks 750 Watt Heater Upgrade Kit to your Monster-Ram for cold-weather starts as low as -30°F/-34°C with block heat and -20°F/-29°C without block heat. Built To Survive This simple bolt-on kit requires no maintenance. Unlike the factory Cummins grid heater, which can fail and destroy your engine, Banks coil heaters are designed to fail safely, avoiding catastrophic engine damage. How It Works Doubles your Banks Monster-Ram's heat output from 750 watts to 1500 watts. Cold Weather Starting Recommendations The Banks Dual-Heat Upgrade Kit is designed around RAM’s block heating recommendations. RAM recommends the use of a block heater at 0°F/-17°C and mandates its use at -20°F/-29°C. Failure to follow these instructions could lead to premature wear and/or failure of key components, including pistons, rings, and cylinder walls.Key Features Installs in minutesIncludes 750 Watt Coil Heater Copper Washer Heater Coil Extension Wire
