The Industrial Injection Remanufactured stock and performance CP3s start out as a genuine stock OEM CP3 and then have been completely rebuilt in house with BRAND NEW Factory OEM parts. We then modify and balance them to a perfect running pump that flow 120% over. The pump work great in a completely stock all the way up to a full built competition truck. We balance the pumps to a tighter tolerance than the original manufacturer and have put a lot of time into making them the best CP3s money can buy.
