2009-2019 6.7L Dodge Ram Cummins Coolant Bypass Barb Leak Repair Adapter Kit

Constructed from aerospace-grade billet aluminum and precision CNC-machined to exact tolerances to prevent warping, cracking, and coolant leaks caused by severe engine heat.

Permanently resolves factory coolant leaks by replacing brittle, leak-prone stock plastic adapters with a heavy-duty metallic upgrade for long-lasting reliability.

Serves as a cost-effective hardware solution that is perfect for owners who already have a silicone hose, need a replacement fitting, or are building a custom cooling reroute.

Improves coolant circulation around rear cylinders #5 and #6, helping reduce heat concentration, lower thermal stress, and maintain more consistent cylinder head temperatures during heavy towing.

Fit: 2009–2019 6.7L Ram Cummins 2500 / 3500 Turbo Diesel (Pickup) and 3500 / 4500 / 5500 Turbo Diesel (Cab & Chassis) models.
