I have an '18 z71 and im going with the 5100 setup. Will go 1 setting below max on billsteins and not sure on the rear tho. I think i will go 1" taller than stock. Will run 305/65/r18 when my stock are done. I like the z71 wheels and will powdercoat. I got a quote for $80 per wheel from a local shop.

You positive a 305 wide would fit?

that size puts it at a 33.5” tire. 

I’m keeping the stock 20” wheels as well. 

(Off a different 2018, but I like the way they look) I wanted to keep the stock Z71 18” wheels but at the time couldnt find a set from a midnight edition.

275/60/20 rubs with bilstein max height. Pretty sure 305 wide is gonna rub, even at 3rd setting.

How bad of a rub you get? Any idea what part is rubbing? the tread of the tire or sidewall?

From everything I've read, i feel like 275/60-20 is going to be max that will work with Bilsteins only (Set to highest possibly)

305/60/18 is 32-1/2" tall, 12" wide, 18" wheel. Couldnt you offset with a spacer?

I'd be interested in hearing where it rubs, and offset? You running 9" stock width on rims?

 

I have the 6112's and 5100's for rear + 2' motofab blocks for rear in my garage. Going to try and get to a shop this week and talk about install, seek additional offset and tire size advice. I've been looking at Fuel and Hostile wheels 20x9 with Offsets ranging from +10 to +20. I was hoping to order wheels and tires online. Can save some decent money + tax. More if you bundle and add TPMS, lugs and so on. I was pretty sure I'd be safe with the 275/60 20 with the 6112 set at max or next setting down. From what I've read, thats a pretty conservative upsize. I think the 305/55/20 is pushing it, but some guys have made it work. 

 

I stopped at a tire shop on Sat. They were busy as hell. One of the guys offered to do a test fitting in the near future. Basically take a wheel and tire that I'm considering (offset + size)and crank the wheel and go from there. He said he'd do the alingment after the level and if I bought tires and rims he'd do the alingment again for free. *I don't intend to have the tire shop install the Bilstein 6112's up front. 

 

I originally wanted to do everything at once. I might do the level first now and then check what additional space I have. If I feel comfortable and have freed up space, I'll order online. If not, I'll try the test fitting and pay a little more. I have 20" rims now with 275/55/20. If I do +12 I'm +.59 farther frrom inner suspension. .55 higher to top of fender. +20 offset and I'm a hair over a 1/4 out from suspension/frame. I know those GM truck wheel wells are tight, but hard to imagine it rubbing.

Not prop up rough country but they sell fender wells that get rid of the rub. You can also cutout where they rub.

Maybe with spacers to offset, but not at +27. You'll probably just move the rub from UCA / sway bar to the fender though.

Stock 20s rub on the front arm of the UCA's. I'm lifted now, so don't have that problem anymore, but with +12 or +20 you'd be fine with 275/60/20.

Can't cut out the suspension and sway bar. +27 with 305 wide, I'd bet you rub more on the inside than you do out.

Sidewall made contact with front arm of the UCA.

I’ve read and read... now my head hurts!

 

on a stock 2018 Z71, that I assume has the control arms everyone hates, if I install the 5100’s on highest or next to highest setting, with a 33” tire (275/60-20) will I have any rub? 

 

 

Yes, you will rub.

I just installed the 5100 Bilsteins on front and rear but left the Rugged Off Road bottom strut spacer in place and have the front struts at stock height with the BFG LT275/60/20.  I have no rubbing.  The bottom strut spacer gave me 1.75” of front lift.  Hope this helps with your decision.

Is this because of the upper control arm on the newer trucks? 

 

I have a 2014 and was hoping to run 275/60R20 on OEM wheels with my 5100s set at the highest setting.  Do you think I will rub with the older UCAs?

    • www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.
    • Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.         
    • I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far. 
    • I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install. 
    • Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
