Fleece Performance 04.5-07 Dodge 5.9L Cummins Coolant Bypass Kit (06-07 Auto Trans)

Fleece Performance is known for building parts that solve common issues, and this coolant bypass kit is a prime example. If you've got a 2006-2007 Dodge Ram 2500 or 3500 with the 5.9L Cummins engine, especially if you've added more power, this kit is designed to help keep your engine running cooler.

The stock cooling system on these trucks was originally designed for engines making around 300-350 horsepower. When you increase the engine's output, the demand on the cooling system goes up significantly. This kit works by rerouting coolant flow to ensure that even the hottest spots in the engine block receive proper circulation, helping to prevent overheating and maintain consistent operating temperatures. It's a well-built solution for managing increased thermal loads.

This specific version is for models equipped with an automatic transmission. It's a practical addition for anyone pushing their Cummins engine beyond its original specifications.
