All new Fleece Performance coolant bypass for the 2019+ RAM with 6.7L Cummins! Our patent pending design seamlessly integrates with your truck for an OE fit-and-finish. Increased Coolant Flow, Decreased Coolant Temperatures: The rear cylinders on the 6.7L Cummins suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the cooling system, especially the rear of the block and blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure. Our coolant bypass kit adds a secondary thermostat, that unlike other brands, works based on temperature instead of excessive pressure. This solves the problem before pressure becomes an issue by ensuring consistent temperatures across all six cylinders. Benefits: Lowers coolant temperature at the rear cylinders Ensures consistent temperatures across all cylinders Prevents damaging coolant pressure build up Complete kit comes with braided hose and AN O-ring fittings to ensure a leak-free installation. Why do I need aFleece Coolant Bypass? One of the biggest issues on the 6.7L Cummins is the coolant flow problem to the rear cylinders. This can cause catastrophic failure or blow outs of the freeze plugs in an over-temperature / over-pressure condition. The Fleece Coolant Bypass is one of the most important additions you make to improve the reliability and longevity of the Cummins platform.

Moisturizing
This lip balm is really nice. I am constantly buying new lip balm, and this has really impressed me. It keeps your lips very moisturized for quite a long time. I thought it was going to be the size of chap stick, but it’s actually the size of an Elmers glue stick, so it’s well worth the price. I will definitely buy again, if I ever run out 😁

This lip balm is the bomb
This lip balm is the bomb! Slight pleasant orange scent and application is smooth and creamy! I don’t think I’ll use any other moisturizing lip product in the future. Love it!
