BD Diesel BD 48RE Valve Body Dodge 2003-2007 1030423

BD's exchange valve bodies are modified, tuned and tested to provide optimum performance in towing and performance applications. These units feature revised valve design, new springs, larger oil ports and proprietary governor piston dimensions. Hand-lapped surfaces prevent internal leakage, while new trim valves increase mainline pressure. The end result is improved shift quality, increased clutch holding capacity, reduced friction and extended transmission life. What's more, BD's Dodge valve bodies allow for first and second gear lock-up-a great feature for slowing heavy loads down steep grades (AutoLoc/TorqLoc required). Add longevity and performance to your transmission, while making your truck fun to drive.
