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

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

Protect Your Legendary Cummins Power

You chose your Ram with a 6.7L Cummins for one reason: unstoppable torque that turns heavy loads into effortless pulls. Whether you're hauling equipment to the job site or towing your fifth-wheel across state lines, your Cummins delivers the muscle you depend on—up to 1,075 lb-ft of legendary torque that made this engine a modern diesel icon.

But here's what every Cummins owner learns: that incredible power creates serious heat. And the factory cooling system has a critical weak point that threatens to cut short your engine's impressive longevity. The rear cylinders receive inadequate coolant flow, creating dangerous hot spots that can blow freeze plugs, warp head gaskets, or even push out plugs under the valve cover. It's the Achilles heel of an otherwise bulletproof engine.

This premium Coolant Bypass Kit solves that problem for good. Precision-engineered specifically for 2007.5–2018 Dodge Ram 6.7L Cummins engines, this kit redirects coolant flow where it's needed most—to those heat-stressed rear cylinders. The result? Balanced temperatures across all six cylinders, protecting your investment and extending the life of your workhorse.

Why Your Cummins Needs This Upgrade

The factory cooling system was designed for stock power levels. But once you add a programmer, delete kit, or simply push your truck hard while towing, those rear cylinders start running dangerously hot. You might not notice it until you're roadside with a blown freeze plug or facing a costly head gasket replacement.

This isn't just another accessory—it's essential protection for any Cummins running beyond grocery-getter duty. And with the 6.7L's reputation for outlasting the competition (many owners report 400,000+ miles), protecting your cooling system now means decades of reliable service ahead.
