This LDS CP3 Conversion Kit is intended for the customers that have ALL the emission intact but want to remove the problematic factory CP4 pump. There is NO tuning required for this kit and will not throw any DTC's.

The 2011-2016 Duramax LML's come equipped standard with a CP4 Fuel Injection Pump. Unfortunately, these pumps are prone to fail and when they do, it will send metal debris throughout your entire fuel system contaminating the fuel rails, fuel lines, injectors, etc. In the prior years leading up to the LML, the 2001-2010 Duramax utilized a CP3 Fuel Injection Pump which have been proven as a more durable pump. Not only are they longer lasting but they are capable of making more horsepower. With that being said, our LDS CP3 Conversion Kit will put your mind at ease. Our Conversion Kit is easy to install with superior parts to assure you that you are getting the quality that you have come expect though LDS. This kit will contain all the parts needed to properly convert your truck over from a CP4 to a CP3 Fuel Injection Pump.
