01-04 Duramax 64MM ProMax Drop In Turbo

$250 Core Charge is required, we will invoice you after you order for the refundable core charge, or pay now.

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 transmission, 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.
