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.

Comfortable Pillow!

For many years, I always bought the same brand latex foam pillow. Unfortunately, it's not made anymore so I took a chance with something new. I'm glad I picked this one! Very comfortable and I like the medium firmness. Not too soft or too firm, perfect for me. There is a very slight odor but it is not overpowering at all and I know it will dissipate over time. I will be purchasing another one soon!

Excellent pillow. Soft but medium support. Fell asleep on it right away and it stays cool. Like sleeping on a cloud.

A Good Night’s 💤

I’ve bought many pillows over the years and this pillow is by far the best for me. I am a back and side sleeper. Finally wake up without a headache or neck discomfort. I bought the medium standard. Just the right consistency. Not to soft not to firm. Stay cool pillow.

Confortable

Excellent support. Always fluffy. It does have a smell but as recommended I let it air out for a day. I also washed the cover and had no issue.
