Should have clarified a bit. I will replace front and rear shocks, that's the numbers I listed if they are the correct ones.

Installed 1500’s in the rear today. Stock height. What. A. Difference!  I wasn’t sure what to expect but WOW!  It rides so much better now, I want to have the fronts done!  The back doesn’t hop around

Hard to tell if it's more shock or more tire since you installed them at the same time.

Install done, for sure an improvement.  Settles a bunch of the bunny hop tendencies and makes potholes more bearable.  Feels more planted on corners for sure.  The ultimate test for me is the highway

Rear AT4/Trail Boss - B8 5100 Series 0-1″ Lift Rear (24-309516)

 

Front AT4/Trail Boss - B8 5100 Series 0-1.1″ Ride Height Adj Front (24-309509)

 

This is what you need if you want t8 change the rancho's in a AT4 or Trail Boss.

Our new RST Duramax finally arrived! I had dealer install the 5100's with the fronts set at at 2", and now the truck looks level front to rear. Front's are # 24-293297 and rear's are # 24-293471. The ride with the Bilstein's is excellent. Added Toyo AT3's (definitely more aggressive looking than the AT2's on our old truck, but much quieter). Side steps are GM's 4" round. Ordered a Leer canopy at the same time as the truck but told still weeks away with production delays. Have various trailers for business and personal use so we are having the Firestone Ride Rite airbags installed at same time as the canopy. This will help keep truck level when the heavier trailers connected and/or truck bed full of gear.

Hi there!

 

I've always run big tall tires but with this truck decided to initially start with LT275/65R18.

For those looking to do this upgrade, here's my review of them.

 

2019 Silverado HC, 6.2L

 

My biggest complaint with the stock suspension was the "kick" of the back end on certain sharp bumps on roadways.  Often, it would make the the truck feel unsettled, as if it kicked sideways a bit, then had to recover to straighten out. I didn't mind any type of floating ride, but that kick wasn't good.

 

Had the Bilsteins put on front and back by a GM dealer (plus a 1 inch block in the back)... think they charged me around $500 for the labor.  Have the front shocks on highest lift setting.  I didn't measure it before, but it raised it quite a bit.  Upon first driving it, it is just a tad firmer than the stock shocks, BUT... because it got rid of 90% of that kick out, bumps actually do feel better, less harsh, and more controllable. It's hard to explain, but a definite improvement over stock.  I've probably put 3-4K miles on it now, and every time I drive it, I'm more impressed with the Bilsteins.  You may not notice a night and day difference, but IMO the noticeable change in ride and how it handles bumps is well worth it.  Going to try some Ridge Grapplers and wheels now to see if I can make a larger than stock size fit.

I hooked up our little fully loaded dump trailer yesterday and with the Bilstein 5100's the ride over bumps was excellent. Zero back end sway or bounce as the shocks are quick to settle the truck down.

 

Only thing of note is the rear springs of this truck are quick to sag even with the tongue weight of the trailer empty. The airbags will definitely help.

Ok, here we go guys and gals

 

I'm been a 2500 guy for 30 years and have always ran stock Bilstein's on my trucks. This is the first 1500 I've had in an extremely long time and as such have a few questions.  Oh, it's a 2020 1500 RST CC Z71 with the 5.3 standard box.  I love the truck especially the ride, quite the difference between the 15's and 25's in ride

 

Anyways, first off the Rancho's sux.  I already have 20k on the truck and I'm looking for shocks.  I'm looking at the 5100's as that is what I've always ran on my 2500's.  I don't care about it being lifted or leveled, ok, maybe a little on level.  What I care about is hauling and towing as after all it's a truck.  I'm thinking of going with the rears set at zero and the fronts maybe an inch, but not much more.  That way it looks a little more level.  But my main concern is the rears as I'm almost always hauling something in the bed or towing.  I tow a 7 x 16 enclosed snowmobile trailer, 2 place pwc trailer, 2 place snowmobile trailer and dump trailer.  Depending on the what I'm towing or hauling the back sags, not what I'm use to with having 2500's.  I'm thinking of getting a set of air bags also.  But the first order of business is the shocks.  Would 5100's  the Bilstein B6 24-293471 be best for the rears and the Bilstein B8 5100 24-293297 for the fronts?  Does anyone think the rears should go up a inch and maybe the fronts 2?  Also, what airbags works best for towing and hauling.

 

Thanks in advance for the help

 

Oh, I plan on running the stock tire size once the factory ones wear out, if that makes a difference.

If you’re running the stock size tires I wouldn’t level it at all. Run some Bilstein 4600’s and call it good.

Hi rv245.

 

I had the Firestone Ride Rite airbags installed last week. What a difference when towing the loaded little dump trailer or the boat...no more sag. Haven't hooked up the travel trailer yet but the tongue weight is close to the loaded dump trailer. With the Bilsteins and airbags the ride quality is great. 

 

Now if only that back ordered Leer canopy would arrive!!

How many weeks have you been waiting for your topper? It’s 10 weeks for me.

I swapped out the stock rear rancho shocks on my '21 LTZ for the 5100's  about 1k miles ago and couldn't be happier.   It's my first ever pickup truck after many years of minivan or compact car driving and the rear end hop over road irregularities was quite disappointing and a bit unnerving.   Thanks for all the info and advice in this thread for pushing me towards the Bilsteins.

 

I did  the rear shocks myself in the driveway, but the fronts will need to be done by a shop.  Fronts appear to be out of stock everywhere I have looked, so it may be quite a while before they can get done.  

 

Have any of you left the fronts stock long term and just switched out the rears?

      2023 DRW Wheel Liners

      By SFC Retired · Posted

      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

      OCI, not when but why?

      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.

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

      By bluev8 · Posted

      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?
