Have read a good bit of this thread but its massive. Seeing if i can get some advice. Have a 2017 Sierra SLT with a 2.25" level kit in the front only. Am looking at getting BFG KO2s put on next week. Keep goin back and forth between 275/60/20 and 275/65/20. I keep reading different tires will fit and won't fit. Also the stamped upper control arm issue. The shop that put the leveling kit said they will just put a steering top on when i get the tires. Is that a decent fix or solution to the rubbing issue? What size tires would y'all that have done it recommend? From what i can gather the 17s won't clear as big a tire as the 14 and 15s. Also any advice between ko2 and toyo at2? Any help would be great

You won't be rubbing your control arm with either the 275/60 or the 275/65, they are the same width as the stock 275/55's, just taller. With the 275/65 you may rub the back of the fender, it's considerably taller then stock at 34", which might be too tall for a 2.25" level. There are plenty of people running 275/60r20s on a stock truck with no rubbing. Rubbing becomes a problem on stock offset wheels when you go wider. I've seen plenty of people, including myself, run 285's on a leveled truck with out rubbing, but once you start getting into 295's and wider, it's likely to rub.

My 2015 Silverado had the RHA bilsteins on the highest notch and barely, I mean barely rubbed with 33x12.5x20 Toyo at 2s. Got this 2016 2500hd and put a cognito level kit on it with bilsteins all around and 295/60/20 (33.9x11.6) and don't rub at all. Some one told me the 2500s wheel well is slightly bigger than the 1500s, but I dunno if it's correct or not, look into it, you could possibly fit a 34. Also, the toyos ride smoothe, are pretty quiet, and still look aggressive. Buddy of mine got 75k out of themafd355f71244765089c39645d3030b39.jpg

Unfortunately this just isn’t correct. I know it should be, because on paper they aren’t wider, but since they are taller, a different part of the sidewall is contacting the UCA’s. I’m guessing you don’t have the stamped steel control arms. I made the mistake of believing what I read on this site, and on my 18, with stamped steel arms, I rub on factory wheels with 275/60r20. I’d love it if I didn’t, but I do.

BINGO! You’re correct sir, same thing happened to me then you’ll need new wheels too. Mine was 2.25” level with new +1 offset 20x9 wheels which then allowed me to have 285/60/20 with slight rub on the inner wheel well liner.

Are all these problems y'all were having stemming from the stamped arms? What is the difference between what was on the 14-15s and the stamped steel ones besides the material? I could Google, but thats no fun. My 1500 was a 15 and had no problems with the 33x12.5x20 toyos, do the stamped steel make that much of a difference?

Angles are different and yes, major difference which them requires new wheel

So how would you correct it, get the 14-15 style arms? Or just a lift and some spacers?

I have 285/65r18. They are 32.5x11.5 No rub. I’ve read that having 20s are different and that you’ll rub with an 11 wide. Some fix it with new control arms.

If you’re going to get a lift then it’ll just work but I’d just get new aftermarket UCA’s and be done with it. Multiple good quality aftermarket uca’s out there, everyone knows my favorite is CST. I hated my leveled truck, had new Bilsteins and still ride Rough. I’ve got the CST 4.5” lift which allows you to keep your stock wheels, your choice up to 35” tires, keeping stock width and turning radius which is extremely rare in any lift. This would be my recommendation but cheapest is $1650 just for the lift plus rear shocks $100 each plus install. If you’re doing a level I’d 100% do a coil over leveling kit with new uca’s which cost same as the super high quality CST Lift. If you’re on a budget, 2.25” front leveling blocks and you’ll need new rear shocks if you add another inch to the rear block.

Imho, don’t rush into this, you’ll 100% regret it! Save up, you never go cheap on your suspension.

Do your homework, do the numbers yourself. Getting new uca’s is no 100% not going to rub. You want as much space for tire flexing as possible.

 

Level $200 plus

Level requires new UCA’s $500 plus

New wheels $1000 plus

New rear shocks if raising rear which you’ll most likely want to do $200

 

This is the cost of the badass CST 4.5” lift which keeps every thing stock width not needing spacers and stock turning radius

I had 275/60r20s on my 2017 High Country about a month before trading it in. No level, stock wheels, no rub. Don't know what to tell you. But they weren't a problem. And yes the HC had stamped arms.

Yep, this is the key. Mine wouldn’t rub stock, but the level makes it rub

You’d be surprised as to how many people actually put out misleading wrong information out there on leveling and tire size especially 15 1/2 - 18’s. In the past, I’ve called out a bunch of BS’ers claiming their tire larger sizes on these model years didn’t rub when leveled even some saying it didn’t rub cause their tires were already on before the level, lmao! And then find them down the road on another thread talking about their rubbing issues.

 

People: Leveling WILL cause rubbing issues on years 15 1/2 - 18’s GM 1500’s running 20” wheels when adding anything bigger than stock size tires. Another thing, leveling will cause your truck to ride rougher than stock especially adding E rated tires which is common on larger tires like 285/60/20’s. You’ll also need to buy new offset wheels in order to get the rubbing to stop and buying new uca’s doesn’t guarantee to stop the rubbing which is why I jumped on the “much smoother than leveling” Badass CST 4.5” lift.

 

When you consider the cost that goes into the leveling parts, wheels, shocks/struts and labor, it’s a no brainer!

 

You should never “ever” go cheap on your suspension, it’s your vehicles foundation.

 

Most trucks that are traded in are traded in due to bad riding trucks caused by people that want the look but don’t have a quality suspension, all lifts are not equal, you get what you pay for. If you’re on s budget? Save until you can afford to do it right cause then you’ll actually not only enjoy looking at your truck but you’ll love driving it too and not need a throw up bag and Advil for the ride along

    • Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package. 
    • So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.  
    • Have considered installing a DC to DC charger in your camper to replace your isolator?  
    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.
