Our LDS CP3 Conversion Kit with SuperStock CP3 Pump is the Conversion Kit to use when you want to upgrade over the Stock LBZ CP3 Pump. The LDS SuperStock CP3 Pump is capable of 650 HP with supporting mods and will supply continual fuel at 4500RPM range.

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. Now you have the option upgrading to the LDS SuperStock CP3 Pump for longevity and performance. The LDS CP3 Conversion Kit will put your mind at ease as 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 LDS SuperStock CP3 Pump.
