When the rail pressure falls off at the top of the run, the injection pump is out of capacity — no tune recovers that. The Exergy 06-07 Duramax LBZ Sportsman CP3 (LBZ Based) Pump (store SKU xrgE04 10305) restores the volume the Duramax LBZ needs to hold pressure under load.

  • Built on a LBZ-based core. That is the donor pump it is machined from, not the vehicle it fits — check the Fits line.
  • CP3 platform — confirm which pump your truck left the factory with, since the families do not interchange.
  • Tested through its full operating range before it ships, so it arrives as a known quantity rather than an unknown one you commission on the truck.

Fits: 2006-2007 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD with the 6.6L Duramax LBZ. The 2007 split is mid-year: later-2007 trucks are LMM and take an LMM part instead.

Perfect for a build that has outgrown the factory pump and is losing rail pressure at the top end.
