The DDP 12mm Stroker CP3 is a brand-new injection pump for Chevrolet Duramax 6.6L diesels (2001–2010). This CP3 stroker unit increases pump displacement over stock CP3 dimensions to support higher fueling requirements while maintaining direct-replacement installation. It’s intended for Duramax owners upgrading fueling capacity for tuned or modified engines who need a straightforward swap to a higher-flow CP3.
