Part # FPE-LML-CP3-10

2011-2016 LML CP3 Conversion Kit with PowerFlo 750 CP3 Fleece Performance FPE-LML-CP3-10


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. Our CP3 conversion kit lets you easily adapt a CP3 to your 2011-2016 Duramax.

This product includes a refundable core charge of $100.00. Please reach out to to begin the refund process.

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.
