At Next Gen Diesel, the 6R140 valve body is one of our proudest achievements, especially due to it's extreme complexity. This is a valve body with many unique challenges that required extensive research and understanding to address and resolve. We are proud to progress forward with a plurality of powerful, durable and predictable 6R140 valve bodies that improve shift time, enhance lockup quality/sensation and demand consistency while attacking all forms of crossleakage. All of our Formula One Valve Bodies are backed by a lifetime warranty!
