And you have no rub at all on a full turn lock?

None at all!  We are going to be putting some BORA spacers on it soon to get a aggressive stance.  These wheels have pockets, so we can run the 1” spacers without issues

That’s literally impossible, you’d have the “ONLY” truck on this forum with the exact setup that doesn’t rub. I put same level on mine with same size tires and got rubbing at full lock, neighbor same, everyone on here the same. You must have a magical truck

Haha don’t know about magical, these tires are pretty narrow.  Also they have about 10k miles on them, maybe that has something to do with it.  They came off of his 3/4 ton Denali when he traded it in

Your father, being it’s your fathers truck and drives it daily does get a rub on full lock, just doesn’t advertise it. Another guy on here denied it for the longest time until he realized his misinformation was costing desperate people a lot extra that wanted bigger tires and then realized they shouldn’t have listened. Unfortunately, very few people on here admit they messed up. Being that it’s an 18, spacers will void your warranty on anything attributed by their installation, dealers HATE Spacers! They cause added stress to your suspension, especially your bearings. Good luck and God Bless

Haha I’ve driven my dads 16’ truck plenty man, and can tell you for a fact that I don’t get any rub at all when I drive it.  On my personal 17’ truck I ran the factory wheels with a 305/55, and it rubbed on the control arms like crazy.  The 275/65 is a skinny tire, idk how y’all are getting rub with it.

Also I’m not worried about running BORA adaptors, they’re high quality, and the worst they can do is screw up a hub bearing.  But so can wider low off set wheels.  It’s part of the game man.

I’ve seen much worse then hub bearings go out, dealers will even attempt to deny premature brake issues, shocks, etc. dealerships will deny practically anything associated with something attached to the truck like a spacer but Bora is the best of the bunch. Ok, Be safe

My personal experience, NO! Once you level, you bring the UCA’s closer to the tires. Either spacers will be needed which I’m not a big fan or my recommendation is to sell your 20” wheels and buy 20x9 +1 offset. Or you could just drive around with just the level?

But what if I replace my stamped UCA's with Rough Country UCA's?

I’m thinking it should be fine but better check with Rough Country.

This is my 2018 GMC Sierra 1500...I put a leveling kit (3” front and 2”rear) on it. I just tried putting 305/55/20 MT tires and there are issues with rubbing on the strut; although the rear would have no issues! What is the largest MT (mud terrain) tire I can run so I can have that mean look to my truck?

That’s pretty high for a level, you’re most likely going to need new upper control arms. There are also better options if you’re to just give it a lifted look like a 5” bracket lift from Rough Country ($1K plus install) which won’t widen your track width or your turning radius and won’t require anything else except new rear shocks. Any level 2.5” or higher WILL cause premature front end wear and tear. Look at the angles on your UCA’s and CV joints, they’re not level with the ground.

Your limited to tire size due to your uca’s being stamped steel, width of the tire is to wide. 285/60/20’s will be a better solution with possible rubbing on the felt liner which we all just strapped it back or use heat gun. I did the 2.25” on my 18 with stock 20’s only to have rubbing with anything bigger than a 285.

Don’t forget to look at your angles, bad angles will cause expensive repairs.

So a question regarding uca geometry. Since say a 2” level is installed on the ones with the stamped steel. Is this decreasing the front wheel track width compared to stock since it’s bringing the uca closer to the wheel? I’d like to know because I have 4 - 1/4” wheel spacers. But if the rear end is already at set track width Obviously, I’d just put them on the front to even things up a little.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
