I haven't seriously looked into a lift with Autoride. I think most folks simply delete that option from the computer and move on as if it was never there.

I see alot of people delete the autoride do to the extra large, stupid highly price stock replacement shocks.[/QUOTE]

It has about 250,000 miles. Not % sure as the odometer quit a few years ago.
285/75/16 Cooper ATP tires.
Uniden 878 CB.

Well, here is mine. I have done more to it sense this picture, but you get the idea. 90 V2500 5.7L 4.11,THM400. It now has a roof rack and a solar system. Full size 6in mattress and soon I hope to add an awning and water storage.

Yes!!!! Here's mine:

2004 Z71. 183k miles. All options including G80.

33" Cooper ATPs
Bilstein 5100, still at stock ride height
Moog sways all the way around
Full interior LED conversion

Spends most of her time as a school bus here in the PNW, but she's got it where it counts off road.

Here is my "build" on ExPo I got here as fast as I could - '07 Suburban Z71

How do you like the bilstein shocks compared to stock?

Working on an 86 GMC Suburban. Lift kit going on next month. Will post pics soon. I love Suburbans

I look forward to seeing it. As you can see I have a 90 V2500 I am building. I would love to see what you are doing with yours.
 
My family always had a suburban as I was growing up. I began to appreciate the usefulness of them at a young age. I learned to drive and took my drivers test in a 1989 V2500. Unfortunately my parents had to give it up with over 460k miles on it. But we got to replace it with another 1989 V2500 with far less miles. I continued to drive that until I made what seemed like a stupid decision shortly after, to trade it for a new 2006 GMC 2500HD Duramax. While I loved the Duramax (the powertrain mostly), I really missed the utility of the suburban and all the interior space. It would be 11 years before another suburban would make its way into my family...

The details of the story and build are reported here: 2004 Yukon XL K2500 LBZ

Glad to have a group that loves and uses their GMT-800's. Probably one of the greatest full-size platforms around.

Here's a pic of our 2004 Yukon HD K2500 LBZ (as I like to call it)...

I have a rig I just picked about a month ago...

2001 yukon xl 2500 SLT
6.0 4l80e
4" Rancho lift
Rancho front skid
Projector headlights
Roland roof basket
Homemade awning
Volant CAI
Supposedly has a hypertch tune
305/70-16 Open Country MTs

Overall, pretty close to stock.....

Needs more off the line power...thinking black bear tune....
 
@Tatertot / @Anak
Agreed, the K2500 series burbs are heavy... over 5700 lbs! before you start loading them up. The 8.1 I think is closer to 6k lbs!
Larger than stock tires without re-gearing the axle(s) makes even slower off the line.

Also the biggest restriction to "off the line power" is the transmission they put in these rigs. While the 4L80/85e series trans are great in their own right, it has a max input torque rating (440lb/ft) that they have to work with.
The 6.0L is a decent engine but thirsty compared to the 5.3L for the additional power you get from it. The 8.1L is a beast (455lb/ft)! But when mated to the 4L80/85 series trans they really need to dial the engine back to keep it under the max torque rating of the trans. The later 03+ 8.1 was detuned further to keep the trans happy. In the pickups, they had the Allison 5 speed (520 lb/ft) behind the 8.1L and while the pickup might weigh a little less, those rigs definitely have more power off the line since they do not need to limit the torque like they do when mated to the 4L80/85.

If GM would have put the Allison in the burbs then we could have had the same fun as the pickup guys. but Allison is 100+ lbs heavier then the 4L80 and with the 2500 burbs getting an 8600lb GVWR they needed to keep the component weight down so that payload capacity could be competitive. The Pickups had a higher GVWR (9200lb) so they could afford the additional weight of the allison.

I've driven a couple 8.1's with the BlackBear treatment and they definitely wake up that motor, but I feel its a matter of time for the trans with that additional torque being thrown at it. If you address the trans then you should be good to go.
That 8.1L was designed and built to be used and abused for 250k+ miles. Probably one of the most durable gas engines GM has built in recent years.
Good luck with your rigs and I'm glad to see the GMT-800 crew who appreciates these rigs for what they are.

Only mod so far is the grille/brush guard. I'm looking more for anything that'll give it an edge offroad without messing with highway/commuter use.IMG_20191015_071911916.jpg

I’m looking for another 2005 z71 now for a business I am going to be operating this year. Need lower mileage and bone stock. I will be lifting and adding some off road gear to it. But it will be shuttling clients around Newfoundland.

Cognito lift kit, with Non bilstien shocks would be a great combo for what your thinking. or, there is a conversion kit now out that you can put coil overs on the front which changes the truck drastically. For the better that is. When I get another one, I am going with those coil overs, and cognito front end parts. The company (i cannot rememeber the name now) that makes the coil overs also make shocks for the rear both of which are rebuildable. pop on a set of wheels and 285s and you are good to go.
 
I'm fine with the stock wheels, but 285s would be nice, and I'll look into the suspension parts mentioned. Thanks!
