Just in time for Summer! Our all-new Fleece Performance coolant bypass for the 2019-Present RAM with 6.7L Cummins! Our patent pending design 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.

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 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 AN fittings
  • Mounting hardware

Warranty:

  • 1 Year Limited Parts Warranty

Fun toy but not as durable as I hoped.
Color: Green
I just rescued a dog from the shelter. She is super sweet and playful but she loves to chew her toys so I needed to buy her ones more durable to play with. This toy caught my eye but I was concerned that it might be too large for my small 7 pound terrier mix. After receiving it, I really loved the colors and the way it looked and my dog loves playing with it. Everything about it is great except that within a few weeks of playing with it, she already managed to make a small tear in it. It's not to the point where I would take it away from her toy box but I just wish it was more durable.

Great for tug of war
Color: Green
All the arms make for a good tug of war toy. It’s tough enough that my 70 lbs lab can pull on it and it’s fine

Durable
Color: Green, Color: Green
We’ve had it for awhile now and it’s still (mostly) in one piece. Has held up well for our heavy chewing puppy. It lost a tentacle but that’s nothing compared to the level of destruction our dog has put other toys through in much shorter amounts of time. Recommend for heavy chewers and will likely buy again!

Not large
Color: Green
This is a lot smaller than it appears in pictures. I was going to give it to a large dog but I’m worried it would be a choking hazard. instead I’m going to give it to a pug. Seems fine quality wise just not “large”
