If you're looking for a little more power out of your LML Duramax, this drop in replacement Garrett PowerMax turbo will give you that, and more.

Designed to support up to 600 RWHP, the Stage One PowerMax features a patented design for increased compressor and turbine flow in order to keep drive pressures, as well as EGT's (Exhaust Gas Temperatures) at a minimum. This turbo is a great compliment for those running a moderate to extreme programmer that use their trucks for daily driving or towing. Due to its ball bearing cartridge, journal bearing cartridge failures are a thing of the past, as well as will provide enhanced bottom end response compared to the factory unit, all while being able to handle higher boost pressures.

Very comfortable office chair
Color: Black
This ergonomic office chair is very comfortable and has good lumbar support and a nice headrest. It includes all the necessary tools and takes about 20 minutes to fully assemble. The height adjust and recline features of the chair work smoothly and quietly. The seat cushion is nice and comfortable. The height-adjustable armrest is also a nice features of the chair. Overall, this ergonomic office chair provides relaxing comfort during long hours sitting with support for your bottom, back, head and arms. It's a good value for the price.

Good quality and arrived quickly
Color: Black
I was very pleased with how easy this chair was to set up. Affordable, arrived quickly. The only reason it isn’t 5/5 is because on of the arms had a small dent, possibly due to not enough bubble wrap during shipping. Other than that, the quality is great.

Awesome chair so far
Color: Black
My old chair can go in the trash immediately because it set the bar so low (picked up from a giveaway - squeaked anytime it's leaned on, always sinking upon sitting on it). This Ergonomic chair blew it out of the water. Happy with this purchase. This chair took me an hour to assemble, which I expected. It feels extremely sturdy and comfortable. Lumbar support feels great! I love the various adjustability options this chair offers. Hope it lasts for many years. By the way, I am 175 lbs, 5'10".

Good buy
Color: Black
Very comfortable. Solid chair. Lumbar support helps a lot. Posture in this chair is great. Lots of support. Seems like a relatively skinny chair though - I wouldn't imagine it to be comfortable for a larger person.
