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.

Great use, no burn. Lasts in the water
Color: White, Size: 6 Ounce (Pack of 1), Style: Baby
Easy to apply! Does leave the white residue look if not rubbed in all the way, but this is effective for sun protection and burn control. Longevity of product remains. No break outs.

Feel the burn - not!
Color: White, Size: 6 Ounce (Pack of 1), Style: Baby
This is by far a more natural choice for UV protection. Sure, your tattoos might take on a slightly bluish tint beneath a layer of zinc oxide, but guess what? Your ink isn’t getting destroyed by the sun. Another great thing — this spray doesn’t contain all those hard-to-pronounce, questionable chemicals you see in a lot of other products. Instead, it relies on mineral zinc oxide, a safe and effective ingredient. Safe enough? Realize that zinc is recognized as part of the US Recommended Dietary Allowance. With that, I think you can trust it to protect your skin. Oh, and your kid's skin too.
