Introducing the Fleece FPE-CLNTBYPS-CUMMINS-19 Cummins Coolant Bypass Kit, a comprehensive solution designed for 2019-2024 RAM 2500/3500 trucks with the 6.7L Cummins engine. This innovative kit is engineered to lower coolant temperature at the rear cylinders, ensuring even distribution across all six cylinders. Key features include a patent-pending, temperature-activated design, OE-style fit and finish, and a leak-free braided hose with AN O-ring fittings. This complete, ready-to-install kit is the ideal choice for enhancing engine performance and reliability.

Product Specifications and Benefits

The kit includes a rear coolant bypass thermostat housing, a front coolant bypass thermostat housing, black braided nylon coolant bypass hose, new EGR crossover tube gaskets, and all necessary mounting hardware. The kit's performance benefits include improved engine reliability and prevention of freeze plug blowouts from over-pressure, making it one of the most essential cooling modifications for long-term Cummins performance.

Practical Applications and Target Audience

Designed for 2019-2024 RAM 2500/3500 trucks with the 6.7L Cummins engine, this coolant bypass kit is perfect for vehicles with high towing demands, performance upgrades, or reliability-focused builds. Its practical applications range from enhancing engine cooling during heavy loads to preventing potential damage from coolant system failures. By choosing the Fleece Coolant Bypass Kit, you're investing in the longevity and performance of your Cummins-powered RAM truck, ensuring a smoother, more reliable driving experience for years to come.
