What's your goal? Most folks level, then put those 33's on. You got them to fit on stock suspension with 0 offset rims, so you have no CV angle issues or stress right now. For me, your truck looks "overstuffed" with too big tires (but I like your rim choice). It needs some height either by a level, a suspension lift, or a body lift.

<just threw up in my mouth>

You're not going to notice any ride difference with the 1" taller block in the rear. The shocks have plenty of travel and you are not altering the spring pack so the only difference you will notice is 7/8" more rake than you have now. Remember to put the fat end of the block to the rear...it's tapered. My truck rides a little stiffer because in addition to the RCX 2" block, I have Firestone RideRite Air Bags on the rear and I have to keep 5 psi in them...it gives me more rake, which is OK by me as I like the rake look. When I am towing, I put about 20# of air in them, so I don't get that nose high look. With the air bags, towing is rock steady.

Brand of block doesn't matter....just don't stack an aftermarket block on top of the OEM block. Rule is SINGLE BLOCK between the spring pack and top of axle.

Tell us more about this size..... Do you think you could have gone one size larger, or is this the limit for a level? How is the front and rear view?....nice and beefy look? MPG loss? Road noise? OK, enough questions for now.

33x11.50 on stock suspension? What's your wheel offset?

I've got the same truck but in DC. Love the rims...mine are the same style, but aluminum and 18". I wish they chromed out the 18's like they did the 20s. I've been thinking about Amps too, but it's hard to justify $1400 steps!

Nice stocker! She'll look great lifted a little with some 33s and Westin Pros.

Add a leaf kits will ruin your ride.....better put in some glue on your teeth. Air bags are a better option for occasional weight in the rear.

You can't tell the .5 difference so it's only worth it if you are going to push the limits on your tire size. .5 will be important if you want to run 295 or 305.....not so much if you want to run 275 or 285.

AO Marshall 17's <-- Offset? Cognito Upper Control Arms <--- No rim interference? Guess that depends on the rim offset. 2" Rear Blocks <-- 3.5" total lift in rear? Sway Bar Delete <--- What is this? Looks good. Post some more!

Never stack blocks...removed the original block and put the RC in alone. The trucks come with 2-2.5" rake from the factory, so raising the front 2.5" and the rear 1" with the replacement block will retain about 1" of rake. That's still not enough if you tow or haul anything, so look into Firestone RideRite Air Bags. It will change your life. If the ride is too harsh for you, going from a 2.5" level to a 2" level is not going to change much. I found my truck road close to stock after the level, so I would put the blame on those 20" rims. Less rubber + more rim = harsher ride. It will only get worse if you go up to a stiffer LT tire. If ride quality and lift is that important to you, than a level may not be your thing. You may need to go to quality 4" suspension lift or a small body lift.

Nice truck, but I'm more envious of your garage. Daayyyyyum!

Run your truck anyway you like, you paid for it. But it's nose high and looks broken.

Don't think you're gonna get much help with this as your first post. Your answer is in the 169 pages before this one. I recommend you start from page 1 and work your way forward....there are many options.

Great thread...the Burgundy and Blue trucks are BADASS! Love the way the blue one has a little rake to it! I thought with knuckle lifts that you could not use stock 18" rims or smaller unless you used spacers (to clear the UCAs), but that 20" OEM rims would work. If anybody knows, please post the answer. I'm real close to rubbing UCAs and swaybar with 275/65R18 on stock +24 offset GMC Z71 rims. Want to go 295/65R18 Duratracs but worried about UCA rub at full lock. Also, the new Nitto Ridge Runners have caught my eye and I'm wondering if I just go 285/65R18 to be safe. But then again....I keep staring at the Burgundy and Blue trucks on this thread.

I'd like to average 17. Not sure how y'all get these high mpg...mine never broke 20 on a tank even when it was bone stock. 20K miles...lifetime average is 15.5mpg. Runs like a top and dealer maintained.

I have a friend with a 2.5 front/rear level running 305/50r20s on +1 Methods and he rubs a little in reverse left lock. He thinks it's liner and not swaybar. No guarantees, but +10 should help a lot with your size tire but most likely will still rub a little at full lock.

Can you post up some front on and rear look pics? Those x10s and the -24 offset make those 285s look really big!

What don't you like about it? It looks level to me like all the other trucks that put 2" or less in the front. If you add .5 up front, it might look front-high. I didn't like mine with the 2.5 in the front so I added the taller rear blocks the same day. I don't mind a little rake, but I can't stand a low looking 4x4.

Badass truck. Thanks for posting all the details (like the overall height for garage fit!). Are you running the spacer on the front to clear the OEM rims or spacers on all 4 corners?

I've had 275/70r18s BFG KOs before and I thought they looked horrible....way too skinny. It's a very narrow treadwidth with no section width to look fatter...hated the look. Might as well stay stock. 285/65r18 and larger is where tires start making a difference in looks. You are wrong on 295/70r18s only rubbing felt with stock rims. They will rub the swaybar and the UCAs and the felt. There are plenty of guys on here running them...one is running a 2.5" Level + 1.5 BL and they still rub the swaybar because the stock offset is too positive. Needs at least a .75 spacer not to rub the UCA and swaybar and also some felt cutting or tie backs. I'm not convinced the 295/65r18 on stockers is not going to rub the UCA or swaybar without rubbing because it's almost 12" wide. I'm running a 275/65r18 Nitto G2 and I have about a finger clearance on the UCA and just a little more on the swaybar. The problem is that I can't find anyone running them with just a 2.5 level on a 2014+. Eventually someone will do it, or I will whenever my Nittos wear out.

Mathematically, yes, you are correct. What I am saying is to go to any tire store and roll a LT 275/70r18 up against stock P265/65r18s. Then take a head-on or rear-view look at the difference. The LT 275 will look thinner than the mounted P265. When mounted, the LT 275s will not flex or bulge in the section width, so visually, all you have is the tread to look at. Thus, the stock P265s look wider than the LT 275s so all you are gaining is height which is only seen when approaching your truck from the side. Everyone else watching your truck roll away will just see the skinny treadwidth. TireRack is a good company, but they charge shipping. I would never buy tires online because if you have ANY problem with them, your installer will tell you the tires are bad....then you have to deal with TireRack to send you replacements. A better way is to go to Sams Club and get their written price (usually $290 a tire) and then get your dealer to price match and do the install with road force balance. Then it's 100% your dealer problem if they won't balance or wear incorrectly. As far as fitment, technically, yes they should fit on stockers (+24) with a level, but if you hold your steering wheel hard against the lock and look at the rubber to UCA clearance with your stock tires, you will see there is less than an inch before rubber will touch metal. Not a BIG deal as you won't be lock-to-lock often, but the 295 GYs (and any decent A/T) are wider and will have knobs on the side that might impact the UCA (or swaybar) on a tight turn or while parking. The only way to alleviate this is to go more negative offset with custom rims (0 offset is good) or run 1" spacers on your hubs with your stock rims (or avoid full lock steering). 1" spacers will require you to cut your wheel studs shorter. GY Duratracs don't come in 285/65r18 but lots of other good A/Ts do. Look at the Cooper STT MAX or Toyo OC ATII Extreme.....they have beefy 285s.

275/70r18 will fit without a level. They are taller (33") but actually narrower than the 265/65r18s your truck came with. Some of the fatter ones like the Cooper STT Max look OK. The 275s run about $100 less a tire than the 285s which is why many people run them. 285/65r18 is 32x11. You lose 1/2" height but gain an inch or more of width. Looks much better than the tall/narrow 275/70. They will fit stock with possible minor rubbing. Fit perfect with a level. 295/65r18 is 33x11.8. Very little selection in this tire size, but look amazing on a leveled truck.
