68RFE High-Performance Towing/HD Valve Body

Are you having 68RFE valve body issues or just looking to upgrade your truck's valve body for improved performance and reliability? RevMax is an industry leader in high-performance diesel transmission valve bodies and our go to choice for 68RFE upgrades here in the shop. There are a lot of other competitors out there offering valve body options and sometimes it may seem hard to differentiate what’s what and why RevMax options may be a little bit more expensive than some, so let us try to help outline the experience and quality you are purchasing with their products.

RevMax has been offering high-quality computer dyno tested valve bodies for over a decade. All of their technicians have undergone extensive training and are among the best in the industry. Unlike their competitors, they do not do any reaming or valve oversizing by hand. Each and every valve body they rebuild is machined on their state of the art Haas CNC milling machines, just like the factory did when they made the valve body originally. By the use of these machines, they eliminate human error that is very common when valve bodies are machined by hand. The precise alignment of the reamer to the bore is nearly impossible to get perfect by hand and this is where the CNC machines thrive. RevMax uses a Rennishaw probe to dial in each valve body to the reamer prior to the valve being cut. This allows tolerances within .0005” within the original centerline of the bore. Hand reaming is lucky to keep .002” tolerances. Being off by just .001” can cause valves to stick and sideload which ultimately lead to complete transmission failure.

Each RevMax valve body has a predetermined protocol that is followed for each valve body type. This protocol ensures that you get the highest quality product each and every time. RevMax does not just go through and replace what is bad on each specific valve body, instead, a standard protocol is followed that replaces all known failure prone parts, even if they are still in good working order. In addition, RevMax then checks over the entire valve body to make sure that non-problematic areas are in good working order and if not, they repair these areas as well.

RevMax has proprietary technology and workflow processes that make their product superior to the competition and have the industry's best testing equipment. To start, they vacuum leak test each and every valve body after cleaning. Finally, each valve body is dyno tested on one of their fully computerized valve body dyno machines. The results are compared against a brand new valve body and the data is then stored and available to be viewed by the customer if requested.
