Lift is 4" or 6"?
 

I'm trading my '85 K30 cc dually for an '89 V1500 suburban (Can't afford the 7 mpg as a daily driver and need a car I can fit the kids in) that I'm planning on setting up for expedition type trips. I will use it to pull my '17 camper (2800 lbs) and for various types of wheeling. I want to set it up to take maximum advange of articulation so no giant lifts with huge tires. I also don't want to cut the fenders. I'm also going to start acquiring the parts to do a cross over steering setup. I'm torn as to which will give the me the best articulation in the field, 4" or 6". Let me know what you all think.

My 1ton has a 6" lift with 315/75/16's (35's) here's a pic to answer your question about articulation.. (I realize this truck is longer than a suburban) If I try hard enough,(like in the pic) I can just barely get the tires to rub the back of the wheel well, but under normal driving and mild articulation, I could probably get away with at least a 38" tire without worrying about touching the stock fender. With minimal trimming, I could probably get a 42" in there..? (I know you said you didn't want big tires, I'm just sayin you probably don't need to worry about trimming your fenders if you have any amount of lift on a square body truck)

I would run a four inch lift kit with 35" tires. I would go with ORD heavy duty shackle up front for another 1/2" of lift with a ORD shackle flip in the rear and HD rear shackles. For smoothness i would get greaseable bushings at the front and rear and maybe a steering box reinforcement plate/brace for strength. For increased articulation a sway bar disconnect kit would help. 35"s arent that big and still give you a good ride and nice off-road capabilities.

I run a 3" and it's done everything I've ever asked it to do. When I first lifted it, I put 33's on it, but then I went to 35's and ran into some rubbing issues that I'm not too fond of. I'm about due for a new set of rubbers, so I'll be going back to 33's.

Very clean burban!

Re: Lift is 4" or 6"?
 

i run 35's with a four inch lift but when i tweek the frame it pushes my tire in my fenders. had to get another pair out of the salvage yard. and for all your rides with big tires i would definately get a plate put on the inside of the frame behind the steering box or your frame will get weak and crack. and i do mean crack. had to get a new frame and everything. maybe im slow on this subject but just spitballing.

i run a 7 inch on my truck have 37's and it tucks no prob no trimming about to throw some 40's on we'll so how the no trimming thing goes...

Re: Lift is 4" or 6"?
 

here is a 6" with 35's. I personally would recommend the 6" if you do not want to cut the fenders or want to worry about them getting hit by the tire.

Here is a pic with the 36" and it's not even flexing a lot and there started to be issues.

Very nice, I'm tryin to locate one of these

Re: Lift is 4" or 6"?
 

I agree either 4" with 33s or 6" with 35s if you dont want to cut the fenders.
