2011-2016 LML CP3 Conversion Kit with PowerFlo 750 CP3 Fleece Performance

Since its introduction, the CP4 has proven to be less reliable and less capable than the CP3 used in previous Duramax platforms, resulting in costly repairs for owners when a CP4 fails. Fleece's CP3 conversion kit lets you easily adapt a CP3 to your 2011-2016 Duramax. In conjunction with the piezoelectric injectors, a CP3K conversion is capable of supporting 600 and up rwhp and a PowerFlo 750 conversion is capable of supporting nearly 850 and up rwhp.
