Product Reviews

  • "Excellent quality, CNC lines fit great, straight forward directions. Power steering pump is louder after install. Only issue I had with the install was the length of the hydraulic lines, the length of them should be corrected for easier install one was too long and the other too short either was they were installed."

  • "I have installed a John Woods Valve Body on each of my 02 F250 crew cabs. Fixed the slow shifts that made them both feel like the transmissions were slipping between shifts."

  • "Great product. I installed it on my 99 f350 and I've saw 1.25 mpg increase since and that was with my injectors on their last leg. I didn't use the mounting bracket like the instructions said. I welded my bracket to the frame up higher beside the filler neck. The hose in the kit is more than long enough for a crew cab truck. I do suggest getting the pick up screens and ball valves with the kit"
