Sinister Diesel 2004.5-2010 Duramax (LLY, LBZ, LMM), Edition Powermax Series 2 Turbo – SD-PWRMAX-6.6-2


Product Highlights:

The Sinister Diesel Powermax Series 2 Turbo uses a larger compressor wheel to deliver quick turbo spool, mid and top-end horsepower, and crisp throttle response in convenient bolt-on package. In addition, this turbo features Garrett Advanced Variable Nozzle Turbine design that allows for increased compressor flow and boost response. This unit is built by the original manufacturer using original-style housings so they are 100% compatible with your GM truck’s Duramax engine for a drop in installation. The turbo’s compressor cover comes finished in our high gloss signature “Sinister Blue”.
