2001-2010 Duramax LB7 / LLY / LBZ / LMM


If you’re looking to up the power of your Duramax, and want to do it with a midsize framed turbo upgrade, look no further than the PPE GT40R Series Turbo Installation Kit. This kit comes with those pieces that you will need to install a 40-series turbo (with exception of turbocharger and turbo inlet ducting) onto a 2001-2007 Duramax LB7, LLY and LBZ/LMM truck. This high quality 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 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.

Vehicles which are not operated on public highways are generally exempt from most regulations, as are some special interest and pre-emission vehicles. The reader is strongly urged to check all applicable local and state laws.

Many of the parts described or listed on this website are merchandise for off-highway application only, and are tagged with the “Special Parts Notice” reproduced here:
