Vehicle Specific
Check if this part fits your vehicle.
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.
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.

What LML CP3 Conversion Kit is right for you?
We've got a number of choices when it comes to CP3 conversion kits, let us help you in the proper selection:
FPE-LML-CP3-NP: Our "No Pump" kit for the LML CP3 conversion gives you the option to select your own CP3 pump for your application. Our kit provides you with all of the hardware you need to adapt a LBZ/LMM based Bosch CP3 to your 2011-2016 LML Duramax.
FPE-LML-CP3-WP: Our "With Pump" kit for the LML CP3 conversion gives you a brand new LBZ/LMM Bosch CP3 along with all of the hardware you need to convert your CP4 equipped Duramax to a CP3. This kit is designed for use with or without a low pressure lift pump. For optimal performance, if the truck is equipped with a lift pump, the feed pressure to the CP3 should not exceed 11 psi when utilizing this kit.
FPE-LML-CP3-10: Our Heavy Duty kit for the LML CP3 conversion features a brand new LBZ/LMM Bosch CP3 equipped with a Fleece Performance 10mm stroker cam along with all of the hardware you need to convert your CP4 equipped Duramax to a CP3. This kit is designed for use with or without a low pressure lift pump. For optimal performance, if the truck is equipped with a lift pump, the feed pressure to the CP3 should not exceed 2 psi. Engine surging may be induced by the additional fuel pressure of a lift pump operating at pressures over 2 psi. If you are intending to combine this kit with a Fleece PowerFlo lift pump, contact us for a lower rate spring for your pump to accommodate operation with this kit. For higher lift pump pressures, FCA table values will require adjustment.
