Default Current upgrades to my Duramax powered Sierra HD



I've been continuing with new mods for my '05 HD. All of the audio/visual upgrades were taken care of in December (2 DVD players, 9" screens, X-Box, back-up camera, Sirius satellite radio, navigation ect...). All of this was followed by the exterior mods (painted grill shell with Precision stainless steel grill, smooth painted mirrors, painted door handles and flares and Denali lights). I couldn't wait to long for the performance upgrades so I installed a Volant induction, Edge with Attitude and MBRP Cool Dual exhaust. All of this feels good but... more is better! I'm planning on upgrading the Allison transmission and torque converter when there is a better selection of performance parts available for the LLY.

The big change in plans is how high the truck will be. This will be used as the company tow vehicle so it will probably see at least 10-12,000 miles with an enclosed 32' car hauler behind it. So I felt it would be better to go with a street look instead. I cranked the nose up about an inch and will be putting on a set of 22x9.5" Weld Evo Velocity 8 wheels and will wrap them with 305/45/22 Nitto 404 tires. I was really looking forward to putting the truck up in the air but didn't want to regret that. I might pick something else up to lift later in the year. The wheels/tires should be on by the end of the month!



2005 Duramax powered Sierra HD - MANY mods going on now!
2002 8.1 Silverado HD - Full Throttle lift, 37" tires, 4.56 gears, Comp Cam, TOG headers, Volant induction plus more! - for sale!
2002 8.1 Suburban -Intercooled Whipple supercharger, 22" wheels/tires + more - 407hp/558 ft-lb torque at the rear wheels - 13.93 @ 95.79 MPH - sold!

Tom that thing is looking killer. Y if you sky it you would loose alot of you howing capability. Why dont you just keep the 02 as your "lifted vehicle"??

I've thought about keeping the '02 but then I tell myself that it won't be driven much so I should sell it. If I was to get something else to lift it would be a used H2. That would look good up in the air and would probably be the winter driver.
