Keep your truck's induction system operating efficiently with our curated selection of 2001-2004 GM 6.6L LB7 Duramax turbocharger accessories. The factory turbo configuration on first-generation 6.6L Chevrolet Silverado and GMC Sierra HD models is highly capable, but over time, worn seals, restrictive plumbing, and brittle oil lines can rob your engine of boost pressure and drive up exhaust gas temperatures (EGTs). Routine maintenance and strategic plumbing upgrades ensure your compressor wheel gets clean air and correct lubrication under heavy load.
At Norcal Diesel Performance, we stock durable hardware designed to seal up leaks and maximize airflow across your turbocharger. Remove restrictive factory bottlenecks with high-flow turbo intake horns that improve throttle response and spool-up time. We also supply complete turbo installation gasket kits, heavy-duty replacement O-rings, and braided stainless steel turbo oil feed and drain lines engineered to eliminate hazardous fluid leaks around your engine block.
Whether you are performing a standard preventative rebuild, replacing brittle factory hardware, or complementing a brand-new turbo setup, we have the specialized plumbing and gaskets your truck demands.
