I don't know much about suspension so I'm hoping I can get some guidance here.  My 2020 Sierra Denali feels like there's a bunch of body roll and on the highway, going over bumps the truck seems to take forever to settle.  Is that something you guys feel in yours?  Do the Bilsteins help with this?  Do they change the overall height of the truck?

Yes. The problem with the oem ranchos is they’re too soft for how many of us want the ride to feel, this creates that bouncing up and down feel a few times before the settle back to the natural level. 
 

The Bilsteins are a firmer shock which means they will return back to that natural level quicker and smoother. This also helps with that body roll feel when turning, the firmer shock will keep the truck more level throughout the turn which create a more solid planted feel. 
 

There are other shocks out there that can accomplish the same thing but the Bilsteins are a common choice because they’ve been around forever, are a quality product and are reasonably priced. 
 

The 4600 series will be for your OEM/Stock ride height. The 5100 series (and bigger brother 6112/5160) are the ride height adjusting ones allowing for an increased front end and if you lifted the rear through a block/add-a-leaf. 
 

After having just replaced my ranchos with Bilsteins I can say I’m very pleased with the trucks feel and they solved exactly what you are (and I was) concerned about.

I just reread your post and noticed you had a Denali. I know that can effect “lifting” because the suspension is a little different than the lower trims but not sure how a simple shock swap out works with the Denali’s “system”

I installed Bilstein 5100s on the rear of my truck after seeing such good reviews on them. Honestly, I can't tell much of a difference. The truck does feel more planted over bumps but I don't notice a difference in the corners. Overall they're a decent upgrade but it's not a night and day difference like I thought it would be. I would probably noticed them more if I were off-road more often.

I just went with the 5100s front and rear. Very nice upgrade! I was able to level out my truck and it definitely feels more planted and less body roll in corners.

You have a denali correct?  I have a AT4 and looking at swapping the suspension out to lower it to a regular sierra/denali height to make it easier to get in and out with my back injury. Been struggling with what all i have to replace. Fro my understanding if i went with the 5100’s, ill have to remove the blocks and run shorter ubolts for the rear and replace the front axle.

I have a LTZ. I would think you would just have to install the front 5100s at the highest setting and then remove the rear blocks and ubolts and you should be good to go. This would leave you leveled out. If you want to stock height you'd install the front 5100s at its lowest setting and not sure about the front axle with this set up.

Shows axles in the factory lift kit package so im assuming if you go to normal height ill need to swap them out. The way i been the last couple days i might have to go even lower. Went to physio today and i could barely get in and out of the truck. Shouldnt have even been driving but had no choice.

Man sorry to hear that snakes. Another thought... have you considered trading in your AT4 for a new/different truck instead of changing out the suspension parts? I'd think you'd get really great value out of the AT4 as-is and in today's market.

Just make sure you order the correct 5100's. There is a part number specific to the AT4 which is a longer shock.

 

I replaced the Rancho's with 5100's in mine. I took out the factory 2" block in the back and put in a 1". I had the front shocks set at +1.1" and now the truck sits nice and level. No axle replacement required.

There isnt anything out there i want. I had a 2016 ram 1500 with air ride. Worked great in the summer, made it easier getting in and out and loading things in the bed but during the winter the air ride system would freeze up and leak. FCA wouldnt do anything about it. Thousands of people with that issue across canada and the northern states. So i traded that in for a 2019 ram 1500 which was a big mistake. 5 issues in 3 months, truck spent more time at the dealership then on the road. After the 5th issue i said **** it and jumped to a AT4. With the options i wanted there was only 2 trims i could go for, the AT4 or Denali. And the denali had way to much chrome and was $22,000 more. So AT4 it was. Love my truck, i can deal with the lift kit, but would make it alot easier and pro’s out weigh the cons on why i should lower it.

I been seeing that. Hard to find any kits made for the 2019+ sierra non at4. Does the bilstein shocks get rid of the bouncing feeling in the rear when you go over a bump?  It literally feels like the ass end of the truck bounces up and lands side ways

It definitely is a better ride than the Ranchos. I haven't noticed any severe bouncing with the 5100's.

    • I’m definitely interested to hear the end result here. 
    • My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.
    • Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken. 
    • Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
