DDP DDPNCP4-422 FORD 11-14 POWERSTROKE BRAND NEW STOCK CP4

The DDPNCP4-422 is a brand-new CP4.2 injection pump, offered by Dynamite Diesel Performance for 2011–2016 LML Duramax trucks. This high-pressure fuel pump is a direct OEM replacement, not a remanufactured unit, ensuring long-term reliability and proper fuel delivery.

The CP4.2 pump is notorious for failure due to poor fuel quality or lack of lubrication, which can lead to catastrophic fuel system damage. Installing this new CP4.2 can help restore your truck’s performance and prevent injector issues, especially if combined with upgraded filtration or a disaster prevention kit.
