Coolant Kit for Dodge Ram (2007-2018) with 6.7L Cummins Engine Black

Coolant Bypass Kit – Fits 2007.5–2018 Dodge Ram 6.7L Cummins (Black Finish)

Keep your Cummins engine running cooler, longer, and more efficiently with this premium Coolant Bypass Kit designed for 2007.5–2018 Dodge Ram 6.7L Cummins trucks. Built to handle the increased heat load that comes with performance tuning and heavy towing, this kit helps correct one of the Cummins engine’s most well-known issues—uneven coolant flow to the rear cylinders.

The factory cooling system works fine for stock power levels, but once you add performance upgrades, the rear cylinders receive less coolant, causing hot spots, blown freeze plugs, or even pushed-out plugs under the valve cover. This Coolant Bypass Kit solves that problem by improving circulation to the back of the engine, ensuring balanced temperatures across all cylinders for maximum reliability.

• Durable Black Finish – Corrosion-resistant and built to handle extreme conditions.

• Performance-Ready Design – Ideal for tuned, towed, or high-performance applications.

• Professional Installation Recommended – No installation instructions included.
