yes my Bilstein shocks on my ReadyLIFT 3.5/3" SST kit are a definite upgrade over stock. Much better ride. Probably can be attributed to both the new tires and the shocks, but overall, it's definitely a better ride than stock.

there's already an entire *active* thread dedicated to this, just 5 posts down

Mine is a bit different than that "rattle" but rather a "gap" in the hydraulic activation that creates a "knocking" when going side to side. It happens at lower speeds. See video. Is anyone having an issue similar to this? *turn up the volume* I just put a lift and tires on it, but this was there before the lift was ever installed! IMG_4293 (480p).mov

true. About $100-120 cheaper and you don't waste the purchase of the shocks that come with RC lift!

yes my installer insisted that it was a great kit and that rough country isn’t the same quality of old. i still wanted better shocks so i opted for the Readylift 3.5/3” SST kit! If people were on the fence like me, and I had access to good shocks, i’d put the rough country lift on there and replace the shocks with fox or bilstein shocks instead. you’re looking at about $1000 all in... and still the cheapest 3” lift kit out there!!

very very interesting and i think that clears it up! i think what we are learning is different installs yield different results from truck to truck. one truck might not have an issue with rubbing or clearance while the next, with the exact same setup, may have some issues. it’s wild!

Interesting! What is the difference in the suspensions between the 2500 HD AT4s and Denali's then? This is a post that I also read that info: https://www.customwheeloffset.com/wheel-offset-gallery/1272819/2020-gmc-sierra-2500-hd-fuel-blitz-stock-stock

yeah it took 30 seconds at the dealership. just held the programming tool at the valve stems and went clockwise around the truck.

yeah it looks like it’s got a lot of upgrades. it has 20” fuel wheels on 37” tires. id love to get a close look at the trimming on this! the AT4s have a 2” lift from the factory so if they lifted it further, makes sense to fit 37s under a 4.5” lift. the lightbars are badass - but again, the AT4 has a better grill for them!

i’m assuming the dealership has to reprogram them? in my previous vehicles you just do it by adding or removing air to and from the tire during the learning process and it identifies them.

why not put it on these trucks? every other model line has this feature... and would it ever be possible to OTA update the truck to include a feature like this, considering the hardware is already in place?

following this! would love to see some hidden light bars with stock grills and bumpers.

yes me too! he’s been great so far. will post pics after i’m finished!

yeah, i got referred to Rocky from another buddy! That’s who is doing it all!

yeah my installer ended up getting his hands on a ReadyLIFT 3.5"/3" kit that I'm going to have installed next week hopefully with the new wheels and tires!

This RC video has a good demonstration of what you're talking about! Both (3" Rough Country and 3.5" ReadyLIFT) include new UCAs with optimal ball joint angles after the lift.

Yeah from my understanding of the suspension, the shocks are going to dictate the ride quality the most, as long as the component angles are similar, if not the same, as the stock angles (UCA, tie rods, etc etc). I think i may put the Rough Country kit on there with Bilstein shocks instead of the N3's. We got word that the ReadyLIFT kit is going to be back in stock mid-October so depending on my install date and my patience level.

Bought my 2020 GMC 2500 Denali at the end of June MSRP $78,655 Dealer Discount of $4492 GM Rebate of $4250 Sale price before tax and title was $69,913 They also gave me $1500 more than anyone else on my trade, so that helped lower payments too, which isn't reflected in the sale price.

I totally understand, which is why I posed the question. I don't want to put a cheap kit on here just to regret it 6 months later. There are two different issues at play here.. cost isn't necessarily an issue because we're talking $600 difference between the RC and RL kits (compared to what you're spending on the entire package of wheels, tires, lift, labor, etc). If it was $700 vs $2500, that's a different convo. 1. the RC kit that i'm (and the original thread question was about) is referring to a "complete" kit, replacing UCAs, shocks, keys, etc... the one that Dunn referred to is their lift kit which does NOT include all of these items. 3" Rough Country bolt on "complete" kit: https://www.roughcountry.com/gm-suspension-lift-kit-95830.html vs. 2" Rough Country leveling kit (*NOT CONSIDERING THIS FOR MY TRUCK*): https://www.roughcountry.com/gm-leveling-lift-kit-9594c.html?find=2020-gmc-sierra-2500-hd-4wd-740565 vs. 3.5"/3" ReadyLIFT Kit: https://www.readylift.com/3-5-sst-lift-kit-front-with-3-rear-with-fabricated-control-arms-and-bilstein-shocks-gm-silverado-sierra-2500hd-2020.html 2. the ReadyLIFT kit is factory backordered with virtually no end in sight. unless somebody knows where to get one soon, it could be months before they're back in stock. so unfortunately, we're up against the supply chain issues and i'm far too impatient to wait an indefinite amount of time for the kit while my wheels and tires sit off my truck. Is it possible to put better shocks on the truck with the other RC kit components? Could you put Fox or Bilstein shocks on there instead? Would that be noticeably better? Just talking through what mine (and others) options are with the current state of offerings for <4" lift kits for these 2020's. There's a lot more options for kits that lift it 5-7.5" but I'm not (nor are others out there) interested in that additional height! Thanks for the replies so far! Would love to learn more about this!

Have you guys used this website? Good for calculating the numbers and getting a very rough look at the difference in tire/wheel position versus stock! This link is my comparison of the stock wheel/tire and the new set I'm looking at 22x10 -18 and 35x12.50r22 https://www.willtheyfit.com/index.php?width=275&aspect=65&diameter=20&wheelwidth=8.5&offset=47&width2=318&aspect2=52&wheel_size=22&wheel_width=10&offset2=-18

Revisiting this thread.... anyone install this kit on their trucks lately? Last post was from May 2020. How's the ride quality? I can't find another full kit that includes shocks with a 3" or smaller "lift". I don't want/care for anything higher than 4".. so this kit seems perfect. If there's a higher quality option, please enlighten me! I want to put on a quality product. I'm putting on 35x12.50r22s on the fuel blitz 22" -18 wheels fwiw. Definitely care about ride quality as well as longevity & quality of the product. I did just find the ReadyLift kit is out now... Found this 3.5"/3" kit from ReadyLift -- https://www.readylift.com/3-5-sst-lift-kit-front-with-3-rear-with-fabricated-control-arms-and-bilstein-shocks-gm-silverado-sierra-2500hd-2020.html That'd be the only under 4" full kit that I've found that's comparable to the RC 3" lift kit. Might be worth the extra bit of money if it provides a better ride quality and superior components! Any more insight? Thanks!!
