Increased Coolant Flow, Decreased Coolant Temperatures The rear cylinders on the 5.9/6.7L 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.
  • Kits for MY 2003+ include billet hose brackets.

Why do I need a Fleece Coolant Bypass? One of the biggest issues on the 5.9/6.7L 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. The '03-'07 5.9L automatic transmission version will eliminate the factory transmission fluid heat exchanger.

The heat exchanger is not a fluid cooler; it was designed for use in cold climates to warm the transmission fluid with the engine coolant. It is not necessary for use in warm climates or high horsepower applications, nor does it detrimentally affect the trucks performance when removed. All ‘07-‘13 6.7 trucks, both automatic and manual equipped transmissions, do not have a transmission fluid heat exchanger.

I'd give 10 stars if I could
Holy cow! This is it! For YEARS I've been looking for a product that would align the bezels on my monitors. I found this product by scrolling through reels and then found the link to Amazon. The price was steep and I was hesitant, but I took the gamble and I'm so glad I did. Installation is slightly confusing, and you really want to know how this works before you adhere it to any surface. I'll break it down for you: Align your monitors flat next to each other. Attach one side with the adhesive, then snap the other side on with the magnet. Peel that adhesive strip and lay it on your second monitor so that they are even. Repeat for the bottom. Twist the U shape up for the left, down for the right. Adjust your angle and then lock them by putting the U shape back to how it was. That's it. The stability on these simple magnets is excellent. I went from a wobbly mount to locked in and only moving when I want it to. I'm so happy this product exists. That's German engineering for you. 💪💪

Works well...but the price!
I ordered two sets to connect 3 monitors together for a workstation at my job. These are well designed and the magnets are pretty strong. Installation is easy and it holds the alignment well. The only issue is the price. For what it is, the price is quite high. The value proposition would be much higher for those who need to be able to not have them aligned from time to time, such as rotating one around for others to see in an office. But if don't need to do this and just want alignment, there are much cheaper options. If you want to go the cheapest DIY route and it won't be seen, some popsicle sticks with two sided tape works well. You can crack them in the middle to act as a hinge.

Awesome product only thing that worked
I originally thought the Screen Buddy was overpriced, but after spending hundreds of dollars trying to perfectly align my monitors for sim racing, this is genuinely the only thing that has actually worked properly. Triple monitor alignment is one of the most frustrating parts of building a sim rig, especially with monitor arms constantly moving or sagging. This finally made everything line up the way I wanted. Expensive? Maybe. Worth it after all the headaches? Absolutely. Great job.

Doesn't stick
The adhesive tape kept coming off. I cleaned and followed the installation instructions, but it still kept coming off. Wouldn't recommend.
