The Fleece Performance coolant bypass for the 2007.5-2012 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.

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 protective high temperature sleeve and AN fittings
  • Mounting hardware

Durable, sensory texture
Color: Blue-Green-Orange
These are fantastic. They are durable and high quality. My dog loves the sensory texture and they satisfy his aggressive chewing. I've bought other high-end, popular brands and he chewed through it in less than two hours. I would definitely buy these again (if I even had to)!

Best purchase
Color: Blue-Green-Orange
These are by far one of the best toys for my aggressive chewer. My pitbull mix loves the football & ball, gave the other toy to my niece's dog. Bought them in Nov/Dec and they have held up great, still look new. I was upset when I saw they are no longer available. I would have purchased more to have some for specific outdoor use.

Good buy
Color: Blue-Green-Orange
Babies didn't use them. Too tough for their mouths. They are to small. Good for a bigger puppy.

Mastiff mix puppy loves them
Color: Blue-Green-Orange
I have experience with large working dog breeds, and I've got a mastiff lab mix puppy, who at 5 months weighs 50 pounds and is teething hard, and chews on everything. Most chew toys I've tried broke within a few minutes, but these have held up. I like that the ones I received are hollow, so I can put puppy kibbles inside them to keep the dog busy in her crate, and slow her eating so she doesn't scarf down her meals and get sick. The hole is small, but I feed small sized "taste of the Wild" brand kibbles, and they would pour out of Kong toys within seconds. I have recommended them to other puppy owners. My dog isn't an aggressive chewer, but for a teething puppy, these toys do seem to be ideal.

Nice material but do not recommended for aggressive chewers
Color: Blue-Green-Orange, Color: Blue-Green-Orange
Why did you pick this product vs others?: The material is nice and easy to wash but definitely do not recommend for large breeds/ aggressive chewers. My big pup ripped one up within seconds of getting it. The ball has lasted!
