The LB7 Promax is basically your stock turbocharger on steroids. Built specifically for the 2001-2004 LB7 Duramax, this turbo is perfect for the 400-625rwhp market looking for better EGT control with a much broader power and torque band to work with.
This turbocharger is a direct replacement to the stock unit, with no other changes to the truck required. Improved air flow from our 63.5mm 6-blade billet compressor wheel along with wastegate modifications makes this the ultimate bolt-in upgrade.
Built transmsision, EFI Live tuning and a lift pump will help reach it's maximum potential. We've seen over 80hp and 160lb-ft gains over the stock turbocharger, with dyno charts in the 620hp range.
