I wouldn't say it stupid in fact MarkMC has a similar setup. I believe his is 2.5" suspension, 3" body lift, 1.5" Spacers and 35" Tires on 18's.

You're going to need to purchase struts all the way around to achieve it though. I would suggest bilstein HDs.

We have struts in front and shocks in rear and they DO NOT have to be replaced to lift. It is advisable to and I would not lift without, but I have seen it done. The struts and shocks will not prevent lifting. The HD's are great up front, but are to short in rear for any real travel.

OP--35's will be ok for street use, but not offroad. Those of us wheeling hard have nothing over 33 and still rub. I do have a set of 34s to try once I mount them up. Another key issue is the width and spacing of your rims and tires. Lots of variables to fitting tires.
My main advise is read alot and see what works. Many have gone before you and you can see what worked and what didnt by reading and it wont cost a dime.

 

To do 35s properly, you'd have to regear or your truck will be a dog on the road.

 

It also depends on your mission. If you want to off-road it, and I am assuming you do since its in this thread, 35's are not practical. Get a decent set of 33's and you will be fine. If your biggest concern is the speed bumps at the mall, feel free to toss some 35's on there. The more lifted exposure for this platform the better!

 

Oh come on matt, I have 35's and wheel mine. I do rub on a complete flex though. But i dont suggest 35's unless you like to cut. I had to cut the **** out of mine to make everything fit right and still turn and everything. BTW hows the leg?

 

I won't be doing hardcore wheeling, just a few trails and mainly mudding.

I'm in Florida so there aren't many hills around here for good hardcore off-roading. I'm gonna try to pick up a set of 33's if I were ever to do that.

The rims are 16X8 with a 22mm offset (I think)

EDIT: How easy/hard would it be to cut the back door?

Tougher or more expensive, I think - than fabbing or buying four adjustable rear control arms to move the rear axle back an inch or so.

 

cut cut cut.................and more cut..i have 33's, just purchased a set of 4.11 gears to comp for the tire size because it dogs pulling the boat....most practical set up and great ride....imo....but hey ...whatever floats your boat..:thumbsup:

 

Alright, it's decided. Once I get the money 16X8 MB Gunner 6 wheels machined finish with Nitto Terra Grappler 285/75/16 tires

Think I'll need to cut the body for that?

 

maybe some light trimming, but prolly not much with both lifts. I have not heard great things about the terra grapplers. I was told they are loud and dont wear even, but that was on a couple full size trucks.

 

My dad just got the terra grapplers, too early to say how they wear, but we've taken 3 highway trips around 340 miles each and they are not loud

 

What about the Kuhmo Road Venture A/T's? Heard anything about those?

 

Heard good things about those and the yokohama geolander at. Lots of good at tires out there for a decent price. And knowing where you are, an MT is a bit of overkill. I had the dueler revo at and swamper on my Burban when I was cruising those red dirt roads. The bridgestones were the better tire for the use, but did not look near as cocky

My fav tool..:thumbsup:

 

Mrs. Roadie got me one for a college graduation gift! After I admired the one her Dad had.

In 1973!

Still going strong, and I've ABUSED that puppy over the years.

 

IMO I would stay away from the yokohama geolander ATs I had a set before my 33" pro comps I have now and I HATED those tires they slid everywhere, etc, etc they weren't good one bit, I would roll on my rims before I had to get another set of those pieces of sh*ts. :hissy:

 

I have 305/50/20's nitto terra grapplers on mine, almost a 33'' but a lot wider than a 12.50....purchased them december 15....i have 29k on them,rotate them regularly and keep it aligned....long story short.....about 1/2 worn and drive like a dream, 3rd set Ive had,and do a looot of highway driving...(100miles a day round trip to work) In my experiance (my 1st set) if you dont keep them aligned and rotated they wear FAST! and they are LOUD!...if you do regular rotations, correct air pressure, and keep it aligned you will have no worries...

 

I have 305/50/20's nitto terra grapplers on mine, almost a 33'' but a lot wider than a 12.50....

305 mm is 12 inches. I run that width.

 

Those blanket statements dont apply. A pitbull Rocker 37 is taller than a BFG KM2 38 in real life on the same wheels.

They offer dimensions on most tire sites, but that is easily changed by air pressure and rim width. Hell even the weight of the vehicle will change the mounted height of the tire. the load range, sidewall strength...it all comes into play. Everyone swears my 305's are the widest they have seen and I have seen 315's that I thought were 285's since they were all-terrains.

Too many variables in tire sizing.

 

Those blanket statement's do apply, "in general", sorry I forgot to baby proof my comments. The MOST COMMON aspect ratio in 16 inch rims is 75, the most common in 17 in rims is 70, I believe, for truck tires. These aspect ratios make a similar height tire skinnier than the most common english tires sizes of 31x10.50, 33x12.50, and 35x15.50. Of course there are different aspect ratios and as many different english tire sizes as there is demand for them. But IN GENERAL you are going to get a skinnier metric tire for the same height (of an english tire) with an aspect ratio of 70 or above.
Yes the tread width may be different, but on the same wheels a 315 will always be wider than a 305 which will always be wider than a 285. That number is the section width in millimeters, if the number is bigger the tire will be as well. This doesn't account for different tread patterns or different wheel widths.
I'm just trying to pass on some easy to use knowledge that can be used in most cases. If you are really worried that much about a tire of course check it's specs. But there's no point in saying "blanket statements don't apply" when in many cases they do. If you want to pull the outliers into the equation of course you can prove just about anything false, but it doesn't mean it's entire wrong. It's useful information to have. Because my 33's are not the same as the next guy's 33's but if mine are metric and his aren't chances are his a probably wider. I'm sorry if you assumed I was making a statement that I meant to apply to each and every case possible. I assumed no one reading it think that, but I guess nowadays you have to design things for the lowest possible denominator, for fear of some idiot screwing everything up for the rest of us. I guess that's why there are warnings on the sides of plastic bags telling us not to put our children in them, and warnings on our coffee telling us it might be hot and it would be a good idea not to pour it on ourselves. Warnings on the bottoms of lawnmowers telling you not to stick you arms or legs into the spinning blades......etc. etc. etc.

 

nitto terra grapplers

Hey all I am new to the site and trailblazers lookin at lifting and mud tires so I was just goin through the forums since pavementsucks.com don't have many trailblazer members. I have been in the full size pickup off roading and jeeping forever and I had a set of 35'' Terra grapplers on a 02 2500hd duramax with a 4" lift did a lot of off-roading and my daily driver and towing cattle and I was never happier with a set of tires no blowouts and they were very quiet or atleast I couldn't hear them at all but again it was a loud diesel. ore even. I have had about three sets of them in 5 years and I drive a lot miles over 120 a day. But hey any good tips as where to get a lift for my 2002 ltz lookin for like a 3 or 4 inch and pry 33" tires. Thanks

You will be at most getting 2.5 to 3 inch from one of MarkMC's suspension kits. There is nothing bigger available suspension wise. There are a couple body lift options for 2 or 3 inch.

I advise you contact MarkMC, a member here that only does lifts for members and you can email him at markmcmaster2003@yahoo.com

He has two kits available now for suspension lift and he developed the 3 inch body lift but has passed the putting together and sales of them to another member. Mark has the best customer service, the best pricing, and incredible products.

 

Hey thanks guys for the info it should be very helpful. We was looking at just leveling it out because they make a kit for the torsion bars on other gmc/ Chevy products but the trailblazer is way different didn't know that till we bought one so now we are lookin at a lift. Originally looked at a 2.5 or 3 inch with a set of 31's any imput would be awesome.

 

Search some of my threads. I have had several different set-ups. Find someone's you like and ask or research what they did.
