I recently changed from stock 17"s to 20"s with 285/50's.

I've noticed that the front-end seems a little "choppy" when going over significant bumps at speed. The stock setup didn't exhibit this and I was wondering if anyone else has noticed this as well. The stock tires obviously have more sidewall to absorb irregularies in pavement but my 285's are not like those rubberband tires I see on other rides. Those vehicles must ride like a skateboard :D

I was thinking of replacing the shocks to something that may eliminate this issue.

Anyone have an idea or recommendation?

maybe replace the shocks like you said with a sport shock...i had one of those trucks on 20's with a 35 series tire....never again....worry too much about bending a wheel

 

good luck

Well, one thing would be to run as little air pressure you can get away with & still get a flat contact patch (use chalk on the tire to verify you have a flat contact patch). More often than not, tire shops will overinflate the tire to max sidewall pressure (which is not necessary unless you're using the max tire weight capacity)

anyone else with recommendations?

I am running 285/50/20 GY Fortera Silent Armor tires w/36lbs. of air road force balanced on GM Silverado SS wheels and have had no problems at all (so far)

KUMHOs here. I have the pressures lower at 38lbs front and 28lbs in back. I like to keep pressures lower in the back so they wear evenly. There's no weight on the rear of an empty truck and the centers of the tires tend to wear out quicker.

Anyway, any recommendations on shocks?

Road Force balancing is your friend!!!!!! I tried KYB Monomax shocks with my wheels. Bad idea because it rode even worse. KYB GR-2 put me where I wanted as far as ride. Pretty pleased.

I kinda have that same problem with 03 sierra. Have 295/45/20 and i get a lil hop in the front. About toget new tries soon but sounds like an idea to change the shocks in the front.

well......I went ahead and bought a pair of Monroe Reflex(not monotube) for the front and i must say that there is a significant improvement over the OEM shocks which only have 2000 miles as this is a new truck. The front-end is more stable over the irregular pavement and not bouncy like it was before. I'm very pleased.

I will go ahead and get a set for the rear as well. The price is fair at around $43 ea.

I installed Monroe Reflex shocks on my 2004 GMC 2wd Sierra Ext Cab this past weekend. The truck had 56K miles with the original shocks and I must say that the ride is much better now. The stock shocks appeared to be okay and were not leaking, however it had a ride similar to that of a boat. The ride is a little stiffer now, but not too stiff.

The suspension is stock with the exception of Belltech lowering shackles in the rear. I have also changed the wheels to the 2007 GMC Yukon 20" aluminum wheels with 275/55R20 Bridgestone tires.

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      2020 Trailboss 6.2 replacement

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
