Manufacturer Description

The Fleece Performance coolant bypass for the 2013-2018 RAM with 6.7L Cummins seamlessly integrates with your truck for an OE fit-and-finish.
Features:

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.

Why do I need a Fleece 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.
Kit Includes:

  • Rear coolant bypass thermostat housing
  • Front coolant bypass thermostat housing
  • New EGR cross-over tube gaskets
  • Black braided nylon coolant bypass hose with protective high temperature sleeve and AN fittings
  • Mounting hardware

Must buy
Flavor Name: Bacon, Size: Small
I've bought multiple of these for various different dogs. They've all loved them. Great for gifts or just because you want to buy. I highly recommend. Seems safe to eat. Lasts a while. It's hard then as dogs chew it, it breaks down. The shape make it easy for the dogs to use their paws to hold it.

He loves them
Flavor Name: Bacon, Size: Medium
My little one goes to town on these.. I have bought several.. I get scare when he chews all of the end down and then looks like little pieces of the fiber are coming off. so I throw away and buy a new one.. at least they are cheap enough to do that for cost. He loves them and nothing else gets chewed.

I will buy this again if it ever wears out! 🦴
Flavor Name: Bacon, Size: Medium
My dog loves it, he’s a Boston Terrier. Perfect size for a Boston. It is well made, doesn’t fall apart and there is no stink! Safe to let dog use by himself and good value for the money.

Only bone for my dog
Flavor Name: Chicken, Size: Medium
These are the only bones my dog will chew on. He loves both the chicken and bacon flavored. I just have to watch him as if they get too small I don't let him chew and will give him a new one.

Size information reversed. Smalls are medium and mediums are small.
Flavor Name: Bacon, Size: Medium
I love the product but the description is frustrating. I ordered the medium size bones expecting the 7 inch bones, but recieved the 5 inch bones. Apparently if you want the 7 inch bones you should choose small instead of medium. That makes no sense and is so irritating.
