Garrett PowerMax GT3788V Stage 1 Turbo for 2011-2016 Chevy/GMC 2500HD/3500HD 6.6L Duramax LML

GRT886976-5004S

Want more turbo for your 2011-2016 LML Duramax without changing how it bolts in? The Garrett PowerMax Stage 1 turbo is a direct drop-in upgrade for the Chevy and GMC 2500HD and 3500HD 6.6L.

Garrett rates it at 19% more flow than the OEM turbo, and it is built to support up to 600 HP (Garrett estimate based on compressor choke flow). A lightweight forged, fully machined compressor wheel is where that extra flow and efficiency come from. It is outline interchangeable with the factory turbo, so it fits the way the stock unit did.
