2001-2007 6.6L LB7 LLY LBZ Duramax Parts

LB7 LLY LBZ Duramax Parts (2001-2007) — EGR Delete, Intake & PCV Reroute

The LB7 brought common-rail injection to the heavy-duty game. The LLY brought overheating. The LBZ brought it all together — but all three generations came with restrictive EGR loops and oily PCV mist that clogs intercoolers and intake manifolds. TruckTok covers the 2001-2007 6.6L with EGR delete kits, high-flow intake elbows, PCV/CCV reroute kits, and SOTF switches for the Silverado 2500/3500 and Sierra HD. Whether you’re replacing LB7 injectors or dropping EGTs on a hot-running LLY, we’ve got the bolt-on hardware.
