Post pics please! Would love to see this. 

Sorry it's been quite a while since I posted. Was out for a couple months with a health issue?
My shop ended up raising my coilovers to a little over 6" and put a bigger block in the rear in order to gain the clearance for my 35's. I measure it at about 7" overall. I feel it's too tall now and my 5 foot wife plays heck trying to crawl up in it. 
Went by the shop today and discussed with the guy and the decision was made to drop back down to a 33/12.5/20 so that it can be lowered back down. My goal was to have my AT4 raised a few inches over the stock 2" and put bigger tires. For whatever reason my particular truck needs to be raised more than I want to in order to fit 35's. So now the goal is to bring her back to around 4" overall and go with 33/12.5/20's. I'll post a few pics in a week or so when it's complete.

I have BDS 2.5" lift - looking to got to same 33/12.5/18 - still on OEM 275/65/18 now - looking forward to seeing how those fit when you are done and how much trimming is required.   Should be a good all around set up.

I am having my 2.5” BDS lift installed Friday on my AT4. My plan is to run 295/70/18 Nitto Ridge Grapplers. Wheel is method NV 305 with 0 offset. Hoping it all fits with just some minor trimming. I’ll post some pics once completed.

Hey Jim.  Surprised to hear you needed so much lift to run 35's.  I have 2019 AT4 with stock suspension and factory 20" rims running NRG 35x11.50 with no issues.  I had very minor rub on the front of the drivers side well liner only when backing with wheels turned full lock right.  This was easily eliminated by zip tying the liner bracket directly behind the bolt that there to one of the bumper mounts.  I've had no rub since.  I think the biggest issue is the wheel width and offset.  I will say though, even with the stock suspension and 35's, my 5' wife still struggles to climb in the truck as well.. ?

It surprised me as well??‍♂️  It could very well be my wheel/combo. With the more narrow tire you are running, could make the difference. I know the Sierra and Silverado have different wheel wells and the Chevy tends to be able to run a bigger tire. There's a 19 Chevy in town that has a 4" Pro Comp lift with 35/12.5/20's that has tons of room around the tire. Set at 4" on mine, the tire would hit the corner of the front bumper. I'll try to attach a pic.

Forgot to add my wheel/tire specifics. My wheels are 20x10 Fuel Siege with a -18 offset. Tires are BFG KO2's, 35/12.5/20.

Got my truck back yesterday!  It's now set at 4" all around and on 33/12.5/20's with no rub anywhere. Sorry for the crappy pics. Freezing rain outside today.

Looks great.  What is your height from the ground to the top of the sharkfin antenna?  I'm trying to make sure it will still fit in my garage!

I get roughly 81" from the ground to the tip of the shark fin as I measure with my tape measure. So I'd say give it one or two either way.

LOL....one or two either way would be the difference between still fitting and not!  I have 82" from floor to top garage door seal.

It would probably be too close for you then. I was trying to hold the tape measure and balance myself on the drivers side threshold, that's why I said give it or take a few. ?

    • Did have to make 1 modification because of the WeatherTech rear mud flaps and that was needing 3 longer screws than what came with the install package. 😄
    • Picked up the liners yesterday. Installed passenger side WITHOUT any modifications. All mounting holes lined up perfectly. Rain is interfering today with drivers side. Very Happy! Will add pics when finished
    • As a matter of amusement I’ll leave this conversation with this. Do you beat the government average fuel estimate? Statistics are a guide to me. Not a rule. Someone once said I have to have the last word. If true and possible may be. I’ll blame that on working in a family business.
    • That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.
    • That makes sense, and I agree with most of that.   I think the product would need both: 1. a default powertrain template, so it is useful out of the box; 2. user-selected priority parameters, so the owner or shop can choose what they want to see first.   Different users are going to care about different things. One owner may care about oil pressure and voltage. Another may care about misfire trend, AFM/DFM behavior, or U-codes. A shop may want communication events and repeatability first. Your baseline point is probably the most important one. Raw data is not very useful unless the report can show what normal looked like for that vehicle under similar conditions.   The way I would think about it is: - start with a basic known-good baseline - learn normal behavior for that specific vehicle over time - allow the event to be overlaid against baseline - show whether the event was a one-time spike or a repeatable pattern - provide a simple severity level, but with clear limits on what that severity means   For example, early severity could be something like: - Info: event captured, no obvious abnormal pattern - Watch: value moved outside baseline, but not repeated - Warning: repeatable abnormal pattern under similar conditions - Critical: communication loss, voltage drop, bus-off, reset, or severe repeated event   I would not want the first version to say “replace this part.” That would be overclaiming unless there is repair-confirmed data behind it. It would be more honest to say “this pattern deserves inspection.”   On the OBD port question, I think OBD absolutely has a role. OBD is probably the right place for: - DTCs - freeze frame - VIN - calibration information - normal scan-tool parameters - Mode 6 / enhanced diagnostic data if available The reason I am still looking at an ECM-side recorder is that the failure may happen before anyone connects a scan tool. If the owner plugs in a scanner after the event, the pre-event evidence may already be gone unless the ECU happened to save it. So I do not see this as “OBD versus ECM-side.” I see it more like: - ECM-side recorder: always armed, rolling buffer, event evidence - OBD/DLC companion: DTCs, freeze frame, VIN, calibration, normal scan data - phone/cloud: status, notes, upload, report generation, notifications   I agree that phone connection and push notifications would be useful. I just would not want the phone or cloud connection to be required for capture. The recorder should save the event locally even if the phone is not connected. The phone should help with event marking, download, notes, upload, alerts, and report viewing.   For a default GM V8 event report, would this list make sense? - RPM - calculated load / MAP - throttle position - vehicle speed - gear / torque converter state if available - coolant temperature - oil pressure - oil temperature if available - battery voltage - commanded AFM/DFM state if available - actual AFM/DFM state if available - misfire counters / roughness by cylinder if available - fuel trims - relevant U-codes / communication events - bus-off / lost periodic message / module reset / voltage drop events Which of those would you remove, and what would you add?
