85 GMC Sierra Classic 1 Ton Crew Cab

[1985-GMC]

Hummer tires will look sweet on it with your wide wagon wheels!

[Mattman2010]

Yes it will. I just gotta find some 6 inch lift springs for the front and do a poor man shackle flip in the rear. And fix brake lines and steering.

[1985-GMC]

I would go for a 4" lift, I think 6" will be too much and get to be annoying getting in and out of every day. To tell the truth if I could do it over I would order a 2.5" lift for my gmc, it already sits higher than the blazer does with 40"s and its only on 33"s. :\

What color do you plan on painting the wheels?

[Mattman2010]

I dont think a 4 inch lift will clear enough for any flex if you drive offroad at all. I don't want to cut fenders. It might get annoying jumping in there all the time but I think I can manage.

I ran 6" lift with 35"s and had about 3/4" between tire and front fender at full lock with flex out on my bump stops. I'm running 8" lift now and I'll have my new bfg baja 37" hummer's on it in the next week or so, if you would like pictures on my crew. I think if you want to run it offroad you would get in the fenders with 6" and 37s. Also if you like the lifted look, it takes more lift to bring it out on 22' Long crew IMO.

Yeah I'd like to see some pictures. I won't be offroading much, basically driving into a field to get a deer or some fire wood. It will mostly stay on the road and act as the dd/tow pig. So 6 inches will be fine for me.

So I figured I would update this thread with the plans I have for this truck. As I would like to here peoples opinions on what they think.

-12V Cummins
-NV4500 - Going to look for either a 2wd Dodge one or a 4x4 GM version, if I go with a 2wd I will find a divorced 205, if I find a GM version I will probably run a NP208 till I can afford to adapt a np205 to it in some way.
-6 Inch rough country lift kit, with a shackle flip in the back. I want to keep my stock 1 ton springs and don't want to have blocks in the rear.
-16.5 Inch wagon wheels painted or powder coated black
-37 inch hummer tires

One thing I am wondering about is the exhaust, I am really thinking about an 8" stack in the bed. The truck wont smoke that much when I get it going but at some point it will. I have always kinda liked stacks but hate how they take up space in the bed. But with the 8 foot bed i think the little space it will take up wont effect hauling anything.

Also the truck has been dubbed "THE TANK" by my friends. They are not around trucks all that much and they love it

[yjheep]

I prolly missed it in here someplace, but what gears do you have

I think this is a 4"

[Mattman2010]

That looks really close to the fenders. I would rather be safe than sorry. Ive talked to several people that ran 4 inch and 37s that have said at full lock they have gotten into the fenders.

I love the height of my truck on 37's. I'm 6'1" on a good day and it's no problem getting in and out. So I think 6" with 37's will have that full wheel well look and not be to high. Good for a driver!

I curled in a fender with a roughcountry 4" w/ 35's on my k10. And that sat a lot taller than a lot of 4" lifts..

Matt, trucks's looking good. I also agree that 4" is not going to work with 37's. Maybe a ford super duty, but not on a square chevy!

[1985-GMC]

Well I guess we'll see with my truck, though my front fenders already have wedges taken out and welded back together on the bottom corners.

Im 6'4 so I doubt it will be much of a problem. I might end up putting some kind of step when I lift it because my dad probably wouldnt be able to get up into the truck and I plan on driving this all the time so if he needs a ride or something he would need to be able to get in.

Thanks man, I am happy with it. I really want to throw some big meats under it because I think it will look really good.

I probably wont be lifting the truck for a while. I should be getting my steering box today. But school starts today also and so I wont be able to put it on till tomorrow. I put dynamat under the heater box so I could at least get heat hooked up. I have a feeling that the dynamat is not going to quiet it down the engine noise that is coming through the firewall. It is more of a high freqency sound deadener so I will have to probably get some dynapad to quiet it down to a comfortable level.

[joe231]

Does your truck have the underhood firewall insulation?
Posted via Mobile Device

[Mattman2010]

No it does not. All the insulation I did have I removed to paint and it was old and fell apart.

[joe231]

Both of my diesels have an insulating panel that has insulation on the firewall and a rubber cover. It covers the entire firewall under the hood.
I'll snap a couple pics for you...

I've never seen one of those installed. I think I found them new somewhere I just can't think of where. I think maybe if I get some dynapad and put it under the dash too, then maybe on the hood and on the firewall right behind the motor that will quiet it down a lot.

I'm pretty sure LMC sells them Matt.

[joe231]

Here are some pics of my crew...

Thanks for the pictures joe! I did get dynamat installed under the heater box so I now have heat in the truck. This truck is long! I've parked in a few places at the college and it's kinda scary thinking I might not be able to get it out haha.the truck is still loud but I'm working on that. I have a leak between my transmission/tcase adapterso I'm going to pull the t-case tomorrow. I need to install my parking break cables. It sucks not being able to walk away from the truck when it rolls so easy.

Get a wheel chalk. Shut the truck off put it in gear. Get out and place wheel chalks, go restart the truck and take it out of gear. Wala! I have to do this to my ford since the great napa ebrake cables stick!

[Mattman2010]

Yeah that would work but I want to hook it up anyway. It will make life easier than starting and shutting off the motor all the time.

Well I have been driving the truck to school for a while now. So far it works great, im kind of on the edge about the 6.2, it does great, but with the 4 speed manual it really seems to lack some power. I did get the transfer case dropped out of the truck and re sealed, but I have not drove the truck for 2 days so I am not sure if it is fixed now or not.
