Manufacturer Description

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.

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.

High energy mindset book, but very repetitive
Format: Hardcover
The 10X Rule is a very high energy, motivational book focused on taking massive action and setting goals much higher than what most people think is realistic. The strongest part is the mindset shift. It constantly pushes the idea that success requires way more effort, persistence, and volume than people typically expect. If you are looking for motivation to work harder and avoid playing it safe, the message definitely hits. It also does a good job challenging excuses and comfort zones. The tone is very direct and intense, which can be useful if you respond well to that style of motivation. However, the book is very repetitive. The same core idea of “10X effort” is repeated throughout almost every section in slightly different ways, which can make it feel stretched out. It is more motivational than practical, so if you are looking for step-by-step systems or structured strategies, this may not be what you are expecting. Overall, it’s a strong mindset book if you want intensity and motivation, but less useful if you are looking for detailed execution plans.

An Excellent, Eye-Opening Read That Truly Makes You Reflect
Format: Kindle
The 10X rule is an excellent book—engaging, interactive, and surprisingly eye-opening. It doesn’t just present ideas; it invites you to actively reflect on your own behavior, decisions, and patterns. As you move through the chapters, you’re constantly prompted to pause, think, and reassess the way you act and respond in everyday situations.

Grant Doesn't Hold Back!
Format: Hardcover
What It's All About... So, the 10 X Rule is a very motivation book about rethinking the way you think about goal setting and the effort it takes to accomplish your goals. Without giving away the obvious, Grant shares that when we go for a goal like, "I want $100 in the next 30 days to pay my bills." We often fall short of that goal and need to restate it as: "I want $1,000 in the next 30 days to pay my bills." Now, if you do far short (happens often), you will still hit somewhere greater than $100. Therefore, we must always 10 X our goals to hit the goals we desire. Now, when it comes to effort, because we often underestimate the action it takes to meet our goals... Our new $1,000 goal requires 10 X effort to hit it. So, if you think "To hit $1,000, I need to make 1 sales call each day." you need to 10 X that number and make 10 sales calls to hit your new $1,000 goal. Therefore, we must always 10 X our effort and change our actions to meet out goals. He also takes times at the end of the book to outline 32 characteristics of successful people that also help in accomplishing these 10 X Goals. Some of those include: Have a "Can Do" attitude, Seek to Solve Problems, Focus on Now, Be Highly Ethical, etc. At the end of each chapter he asks a set of questions that helps to reinforce the material you just read. My Take... Overall, this really juiced me up and got me to rethink the way in which I look at goals and the actions I need to meet them. When reading such a book, I often get so inspired that I shoot off goals without really appreciating the amount of effort it will take to hit them. I walked away from Grant's book with a firm idea on the big goals I want to hit and a healthier understanding of what it's going to take to get there. The overall feel of the book was also inspiring because Grant is the type of person that believes in going for goals, even if you don't know exactly how you are going to accomplish them... Just get started. I resonate with that line of thinking. If you like listening to audio books, Grant does his own reading of the book, which gives a greater sense of emphasis and passion behind the content. Who should read this... Entrepreneurs, Business owners, High School and College Students WARNING: There is some cursing.
