Mishimoto 2019+ RAM 6.7L Cummins Thermal BypassThe transmission is the backbone of your RAM. Its responsible for transmitting large amounts of torque from your 6. 7L Cummins powerplant, and that torque generates heat. If that heat isnt dissipated, it can destroy your transmission. The transmission cooler does a good job of keeping trans fluid temperatures in check, but only if the fluid can reach it. The stock cooling system of both the 68 RFE and Aisin AS69RC utilize an in line thermal bypass

The transmission is the backbone of your RAM. It’s responsible for transmitting large amounts of torque from your 6.7L Cummins powerplant, and that torque generates heat. If that heat isn’t dissipated, it can destroy your transmission. The transmission cooler does a good job of keeping trans fluid temperatures in check, but only if the fluid can reach it.The stock cooling system of both the 68-RFE and Aisin AS69RC utilize an in-line thermal bypass valve that controls the flow of fluid to the transmission cooler. The purpose of this valve is to prevent transmission fluid from flowing to the cooler until it reaches operating temperature. The thermostat inside this valve is prone to failure, however, and when that happens, the fluid never flows to the cooler and the transmission can overheat. That's why Mishimoto has developed an improved thermal bypass valve kit for your 2019+ Dodge Ram 6.7L Cummins. Our CNC-machined aluminum thermal bypass valve not only looks better than the stock unit, but it performs better too. The Mishimoto thermal bypass valve utilizes a replaceable thermostat that is more durable than the stock thermostat and opens about 10 F earlier. This allows fluid to flow to the cooler sooner, without over-cooling. For owners in hot climates, the Mishimoto valve includes a bypass that allows full flow to the transmission cooler, regardless of temperature. The bypass can be easily swapped out with only a wrench for summer or winter driving. The Mishimoto thermal bypass valve flows better in both configurations than the stock valve for more effective cooling. Cooling fins machined into the valve body add even more heat dissipation. This 2019+ Dodge Ram 6.7L Cummins Thermal Bypass Valve Kit is built to last a lifetime with a durable black anodized finish and our Mishimoto Lifetime Guarantee.

Total Glow in the dark entertainment
Color: Glow in the dark - L
This toy is my Aussie Shepherd’s favorite. It is durable. I love that in addition to playing fetch, the tabs make it possible for my dog to swing it from his own mouth and throw it in the air. The glow-in-the-dark feature is amazing! I throw the ball in the pitch black yard and watch it run back at me as my dog comes towards me. It's fun to watch!

Straps don’t last
Color: Glow in the dark - L, Color: Glow in the dark - L
My boyfriend’s dog chewed off all the straps in the first day. Decent ball, but why have straps that dogs can chew off so fast.

Fine choice for smaller dogs
Color: Green-M
A good choice for smaller dogs. My mini poodle enjoys flipping this around and playing tug of war with her humans. She cannot be left with it for any unsupervised play, because she was able to begin shredding one of the straps in a matter of a few minutes. The included pump works great.

Toeless wonders. Love em!
Color: Classic Color
Not gonna lie. These are a God sent when you have an issue with your toes. I hate my toes feeling constricted so these are phenomenal! Comfortable and well worth the money. I also like my socks thin. If you wear boots or hightops, these might not be what your looking for. I do adore the different shades and you can wear them one way or the other as one side is longer. If worn one way, they are higher up the ankle and vice versa.
