LBZ Duramax Turbocharger

Maximize horsepower, drastically lower exhaust gas temperatures (EGTs), and improve heavy towing capabilities on your 2006–2007 Chevy Silverado or GMC Sierra 2500HD/3500HD with our selection of LBZ Duramax turbo upgrades. While the factory variable geometry turbocharger (VGT) on the 6.6L LBZ provides decent spool-up, it can easily become a severe airflow bottleneck when pushed with aggressive custom tuning, larger fuel injectors, or heavy workloads. Furthermore, high-mileage factory turbos are notoriously prone to sticking vanes caused by excessive soot buildup, leading to poor drivability and reduced power. Upgrading to a high-performance turbocharger solves these issues by forcing a significantly larger volume of dense, compressed air into your engine. Whether you are looking for a highly responsive, drop-in replacement VGT with a billet compressor wheel for a daily driver, a rugged fixed-geometry BorgWarner swap for ultimate reliability, or a massive twin compound turbo system to support competition-level horsepower, we have the exact airflow solution to meet your goals. We supply premium turbochargers, complete pedestal kits, and installation hardware from trusted industry-leading manufacturers like Fleece Performance, BD Diesel, Garrett, BorgWarner, and HSP Diesel.
