Just wondering if anyone else has ordered a 2007.5? I went with a Sierra HD (cc,lb). It should be built next week and I expect to take delivery by the end of this month. I was surprized to see options like remote start, brake controller and power sliding rear window (that might have been available last year). I went with most of the available options but didn't upgrade the radio. I'll be going with an aftermarket head unit so it wasn't worth the upgrade.

I have quite a few mods planned for next month. They include -

Pioneer AVIC Z1. This has a ton of features!
9" Vizualogic screens in the front head rests. One will have a built in DVD.
Back-up camera mounted above the trailer hitch. My car hauler also has one mounted in the rear.
12 volt power.
Feed for an X-Box in case I want to add one later.

HID low and high beams. I'll also wire the lows to stay on with the high. Same for the fog lights.

AMP electric steps.

Spray in bed liner.

Willwood brakes when they are available. 16" rotors up front with red 6 piston calipers.

Basic performance mods as they become available. Westers is working on tuning now. I'm running their race tune in my '05 and I'd like to use the same one in the new truck. It will be interesting to see how much power the new transmission will hold. I'll go with a Suncoast tranny and converter if needed.

I like the aggressive look of the stock grill. That will probably stay unless I see something I really good from the aftermarket.

The one thing I'm hung up on is... what to do with the suspension, wheels and tires. I cranked my '05's torsion bars and run 22" wheels/tires in the Summer. The size drops down to 20s in the winter. Ideally, take the '05, raise it 2" all around, wrap one to two more inches of street rubber around those wheels and that would be perfect for me. But, that's easier said than done! To get the added height I'd have to go with a lift kit and at least toss 2" blocks in the rear. So that leads to a little is good but more is better. And then there is to much because MA doesn't like lifted trucks. These are my 3 options -

A - Crank the bars and run 22s like I did with my '05.
B - Go with the Cognito leveling kit, crank the bars and add a 1" block in the rear.
C - Go with a 6" lift, maybe set it at 4-5" to keep the ride good (leaning towards Cognito) and have the BS for the front wheels tuck them in The Cognito is only supposed to widen the front track by 1/2 an inch. Not bad but I really don't want wide track look. I wouldn't be happy with that. I like the tires to be tucked under the fenders.

That should probably wrap up everything. I'd like to have most of this complete by the end of April. I'll probably have to wait for some of the performance mods. I'll then wait to see if the tranny/converter will be needed.

I'll post pics as things progress.

Cool Man, Its Nice to have a New Project! I dont think youll be disapointed. I wish i could have got the Remote start and Brake controller on mine! For 47 grand my door handles should be gold! keep us updated on your new ride.

 

One other thing that I'm looking forward to - heated windsheild washer fluid. Makes me wonder what cars and trucks will be coming with 20 years from now.

 

Does the New design also have adjustable pedals?

 

That remote start is gonna be great for the diesels. I really like the look of the HD GMC trucks.

 

You should love your new truck.
I work at the D-max plant where the Dura max engine is built.
We test every engine before it leaves the plant.
The 07 engines are hitting 400 hp and 775 t after some run time.

 

Wow! What were the LBZ's Dynoing at? they have to be close if not right with that number. So where exactly in Moraine Oh.? from say canton Ohio.

 

Adjustable pedals are also available.

Sounds like GM might have underrated the LLM?

 

I really dont know about the other engines. I just happen to be working in that area that day and was asking the operator about them.
We are just south of Dayton, next to the Truck and Bus plant where they build the Trailblazers.

 

I just got mine last friday and im very happy with the truck.
