New 03-18 Dodge RAM 5.9 & 6.7 Cummins Coolant Bypass Kit | 2003-2018 Dodge RAM Cummins 5.9L / 6.7L

The 03-18 Dodge RAM 5.9 & 6.7 Cummins Coolant Bypass Kit is designed to enhance the engine's cooling system, especially for high-horsepower applications. It addresses the issue of rear cylinders experiencing higher temperatures, which can lead to pressure buildup and potential freeze plug failure.

The kit includes a secondary thermostat that maintains consistent temperatures across all cylinders, preventing excessive pressure. It features AN o-ring fittings and braided hoses for a secure, leak-free installation. For 03-07 automatic models, the kit also eliminates the factory transmission fluid heat exchanger. Comes with a 2-year warranty.
