GT42R Series Turbo Kit with Garrett GT42R Turbo


2001-2007 Duramax LB7 / LLY / LBZ


PPE and Garrett have had a long and beneficial relationship. Having worked together on many projects over the year and knowing the quality of the Garrett is why PPE choses to use Garrett turbochargers as their turbocharger of choice in their GT42R Series Turbo Kit with Garrett GT42R Turbo. The kit comes with those pieces that you will need to install the 40-series Garrett turbo onto a 2001-2007 Duramax LB7, LLY and LBZ truck. This high quality Garrett GT42R Turbo Kit features a design that supports the weight of the turbocharger with a metal framework, not with just the intake tubes. That pedestal features a 1/2-inch thick T4 steel flange and heavy wall 304 Stainless Steel tubing. Also included with the Garrett GT42R Turbo Kit is a 304 Stainless Steel mandrel-bent 3-inch diameter down pipe as well as all mounting hardware, gaskets and hoses needed to complete the job.
