I'm new! 2003 Yukon Denali

[HiHoeSilver]

Hello from Northern AZ. I have a 2004 Yukon Denali that I too off-road and people think I am crazy for it. I have not lifted it, but I have deleted the stock suspension set up for a Bilstein set up. These shocks have performed absolutely phenomenal on and off road. While I have not taken the truck on anything too technical that a Jeep may go on, I have pushed this thing pretty hard, through most types of terrain including mud, snow, and ice. It has performed great and I have never had any issues regarding traction or possibly getting stuck.

It is really great finding people who off-road in these tanks and if you ever have any questions, ill do my best to answer!

Which bilsteins did you use?
Wheel/tire setup?

Went with the 5100 series shocks. Also replaced my rear coils because I heard I needed to since no more air shocks to help hold up the rear end. Wheels are stock Denali boys, and tires are 265/70/17 Falken Wildpeak AT3W ( Could Definitely Fit Bigger Size )

Welcome. Good looking Denali.

We do probably have an infinite number of places to off-road in Oregon. I'm in Corvallis but don't get off the beaten path much. I have a 2003 Tahoe, and am curious what you did for an audio system. I have a Bose system but the radio/CD needs replaced.

Hi I'm new here too.
From houston tx
I got a 2002 denali awd with airride

Everyone is saying they deleted the autoride
How? Did yall simply take the fuse out or bypass the compressor?

I heard to get rid of the wobble to get a double cardan joint. Rough counter sells one for about 500$ I think. It's the whole driveshaft too.

I'm going with a similar setup as well
Blistein shocks
2 inch level.
Keys
Double cardan joint
And spacers in the rear
But I'm using my stock 17s to fit 33s/285

Has anyone done this? Thank you in advance

Hello, do you think you could have fit p285/70r17 wildpeak at3w's on stock height and wheels ?

I wouldn't look for a response from him. This is an older thread and he hasn't been on here in nearly 3 years.

Hey everyone in Chase! I got my bone stock Yukon Denali about a year and a half ago from a gmc dealership with good records, regular maintenance and in very good condition. First thing I did was audio. Recently I've been getting into offroading though. Only light stuff but I would like to hit some trails. I got 285 all terrain tires with some black wheels, i read that they wouldnt rub, and they rubbed bad in reverse turning. Ive done a bunch of research but can't really find much info on the suspension and AWD system, and I'm no mechanic, but I always heard it's basically not possible/stupid to modify. But I'm stubborn, and I love my truck so I got the rough country 2 inch level tortion lift. with new front shocks. I think. It rides perfect, sits taller, and the tires don't rub. Only downside is when I floor it, it wobbles really hard. like really hard. I can still get up and go real quick, it's only when I really floor it. But I shouldn't drive like that anyways lmao, so I shouldnt complain. So I have a few questions, anyone out there with the same model? Anyone know about the AWD capability offroad? And does anyone in the Portland area want to hit some trails sometime?
Nice to meet you all!

Do you still have it ? Curious on the pix with the lift. I too want to get 285/70r17 but a little worried about rubbing. I eventually want to lift it around 2”

Welcome from Utah, I have a 2002 Yukon Denali that i use off road as well. I have lift keys in the front and Z71 springs in the rear with the autoride shocks replaced with Procomp shocks. I did add a 1" jounce bumper extension to the front to eliminate the wobble affect caused by the torsion lift. The jounce stops are supposed to be in contact with the lower control arm and act a progressive spring to support the torsion bar suspension system.

I have taken Yukon through many trails including Fins and Things at Moab with no issues at all. I have also been on some "Jeep" trails that where quite steep and technical as well. My observations on using my rig in these situations has been overall positive. My only downside is that the AWD transfer case is single speed, meaning we have no LO gear. When I have had to climb a shelf or a steep incline, my engine has had to do all of the work with out the help of low gears. I have been in one situation where i had the Yukon in a torque stall where i did not have enough power to move over the obstacle (traction was not an issue), where if i had a two speed transfer case, i would have been able to clear it with out issue.

Speaking of traction, our G80 rear locking differential provides torque biasing for the rear so that if one wheel losses traction, the other wheel will receive torque to help get out of the situation, but you have to be gentle with it, too much torque too quick and it will break. My 2002 has the NVP-149 AWD transfer case that has a viscous coupling that provides torque biasing to my front wheels which can send up to 100% of the torque to the front wheels if both rear wheels loose traction, I have no traction control. The 2003 uses a different transfer case (BW4481) that works in conjunction with the traction control (ABS Brake system) to provide the same torque bias to the front wheels. I am not sure how the traction control system would hold up under extended extreme situations.

I hop you enjoy taking your rig to the outdoors and exploring, they work well in most situations you will encounter but they are not a purpose built off road machine to tackle trails like the Rubicon and such.

lmao yeah i got high centered and all the power was going to the front, it was stupid. i managed to get some logs/rocks under one tire, then the other would spin. quite the day.

pshhh of course! and after the lift i dont think i was rubbing anymore, but it may be partly due to the extreme wear on the tires from whatever the issue is, that im still having to this day. i ended up going stock tires after moving to florida. it was pretty much flat on the left on the outside fronts not bad on the outside fronts and the rears had plenty of life left. its mainly the front left. ive had it looked at by multiple places it seems like they fix it then after a day or two its messed up again. curious about what you did! and yeah heres some pics sorry its a little late!
