Nice! happy to see more GMT800 on the site lately. The Suburban with BFG K02 33" and G80 lockers makes it really capable off-road! I just did a trip over moderate terrain (rocks) really happy that it rolled over rocks easily with 33" vs others in group with stock 31" and the additional lift provided clearance. Without the lift more rocks would have touched the undercarriage for sure only touched twice (too much speed).

'02 3/4 ton 4WD, 8.1L, 4L85E (MN8), G80, 4.10...

LT Autoride, captain's chairs, barn doors...

I think it has just about every option except for Quadrasteer.

120K on the clock

Pretty much stock, pretty much trouble free.

Bought in the summer of '08 when gas was $5/gallon. It is one of my best success stories of market timing.

Nice gotta post up some photos. What are your plans? Do autoride equipped Suburbans allow for aftermarket lift options? No autoride or quadrasteer for me either or stabilitrac. I would have opted for Stabilitrac but 2500 where hard to come by.

I honestly don't have plans to make many changes to the Suburban. We just use it.

Keep in mind, for off road purposes I have my XJ Cherokee. It is the trail rig. The Bride isn't into boondocking, so it is just me and The Varmints there. The Suburban does the campground trips and more civilized sort of things that The Bride is more comfortable doing.

What few changes come to the Suburban are more matters of maintenance. Things like fixing the T-Case pump rub issue. Now it has a billet Merchant Automotive pump in there. The front steering links will probably also get upgraded at some point, as I know those are a weak point.

The one major change I would love to make is to swap in a Duramax/Allison combo. I have that in my work truck and love it. Problem is it would never pay back the cost and effort.

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. On 2500s the Autoride is a matter of electronic valving in the shock absorbers. I doubt there is much that can be done with that. It doesn't much matter to me at this point. The stock tire size is what I am running on three vehicles, and probably eventually four vehicles. If I wanted to go with bigger tires on the Suburban I would be looking at bigger tires on all four of those vehicles, and I don't see that in the cards at this point.

How do you like the Black bear tune Zuksami? Also do your tires rub?

Hands down it's my favorite mod. The burb has a different attitude now. The shifts are much quicker and firm, there is no hesitation between gears. I have more power and gained 3mpg. I was getting 13mpg now 16mpg. I commute over a couple small mountain passes before the truck would have to downshift into 3rd to maintain speed. Now I can stay in 4th and still accelerate. And while towing I used to have to keep her in 3rd to maintain 65mph but now I can leave her in 4th and still accelerate. I highly recommend blackbear! I did the 87 octane tune because fuel is already expensive but they said that if I went with the 91 tune it would add another 10-20 horse power.

Oh and yes my tires rub, but just minor. I have not seen any damage to them.

I love that place! I know I got some stuff planned for the next 2 weeks so it will have to be after that. Some of the guys here are taking about a hollister hills trip on 8/26. I'll be in hollister that weekend so I'll be there. You should try to come also.

Did someone say Hollister Hills? Damn, I'll be in San Diego that weekend. Be cool to be out there with other Burbs.

I'll be in hollister visiting family for a few days. I think the guys here are talking about going on the 26th a Saturday. I think a few of them are camping but not sure. I'll just be doing a day trip. They are talking about it in the Nor Cal Meet Up post.
