Superior Cooling for 2006-2007 Cummins Engines

Protect your 2006-2007 5.9L Cummins engine with the Fleece Performance Coolant Bypass Kit. This system is engineered to solve the cooling limitations of the stock setup, which often struggles to keep up when horsepower is increased. By effectively bypassing the thermostat to allow for better coolant flow, this kit prevents the rear cylinders from reaching dangerous temperatures, protecting your engine from head gasket failure and other heat-related issues.

Engineered for Reliability

• Specifically designed for 2006-2007 Dodge Ram 2500/3500
• Reduces thermal stress on the cylinder head
• CARB EO: D-834-9 for emissions compliance
• Robust construction for long-lasting performance
• Comprehensive kit includes all necessary components for installation

This kit is essential for anyone running a tuner, larger injectors, or upgraded turbos. When you increase the power of your Cummins, you increase the heat, and the factory cooling system simply wasn't designed for that extra demand. The Fleece Performance bypass kit provides the necessary thermal management to keep your engine running cool and reliable, whether you are towing, racing, or daily driving. Don't risk your engine's health; invest in the best cooling technology available. Shop the full range of diesel performance parts at GGCRACING.
