LBZ/LMM Based Duramax Stroker CP3 Pump

The image of the pump, is the actual pump as mounted and plumbed on our testing platform. The outlet fitting will be replaced with the blanking fitting, this is a normal side outlet LBZ/LMM pump.

We are the “OG Stroker Pump” producer from 2007 until today.

Price includes a $300.00 refundable core charge, which will be refunded upon receiving you usable core. Refunds will not be given for cores that have internal rust damage, or physical defects making it non-repairable.

We start with the best pumps to base our modifications upon, if it is not new, surplus new or a used pump that provides no less than 98% volumetric efficiency, then we do not use them to build Strokers.

We now make our pump shafts 100% in house, no outsourcing whatsoever except for the raw materials. Shafts are heat treated and OD ground between centers to +/- 5 Microns, for concentricity. We can easily make different strokes and offer from 9.5MM to 12.6MM currently.

Comprehensive flow data sheet will be provided, for the exact pump you are purchasing.

We no longer perform any modification to the FCA/FPR/MPROP, so this pump is sold without this part and you may simply reuse yours, from your old pump (if it is good). We no longer mod the MPROP because tuners have become very lazy, this was not the case 10 years ago. So to save grief on both ends, just install a stock replacement.

If you can use a higher flowing MPROP, please contact us and we can provide you with one.

This pump can be used on any Duramax application with the correct MPROP. The fuel supply to the CP3 can be boost referenced to gain some additional flow above idle, while idle pressure must be kept below 9 PSI to maintain commanded rail pressure.
