Side shots showing rake

This looks great! I have a High Country with 6.2 and plan to set the fronts at max which is 1.5”. What are the stock specs on your truck, 5.3? I’m trying to determine if I’ll need a 1” rear block to maintain the stock rake. I use my truck primarily for towing and hate the squat when my trailers are connected.

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

It’s a 5.3 SLT. I did have to add a 1.0” rear block to get the rake. Ebay special

This may sound like I dumb question but I fully believe in “getting it out there”

 

Regular Silverado Z71 with no rear block at all. But if I were to (1) add a 2” rear block or (2) add a 1” block and get another 1” from add-a-leaf... would that mean the 5100’s for the Trailboss would be the best to go with? Get the extra length? 

Did you end up doing this? Did you get bump stop extensions?

 

I think it would be:

Front:   Adjustable B8 5100: SKU 24-293297

Rear:    24-309516 For trail boss 0-1"

Rear block (2-3"): Rough Country  2" Universal Block SKU6592 + u-bolts

 

Anyone have any experience towing between stock and these? I've got a 7100lb (uvw) travel trailer on order and wondering if it these will be better or worse under load.

Somewhere in this thread it was indicated that the Bilstein 5100's for the TB have 3 settings: Stock, 0.5", and 1.1"......Couldn't you set the front Bilsteins at the 0.5" setting and then keep your

leveling kit (I assume it's 1.5" spacer) which would give you 0.5" less rake than you have now?  What about adding the spacer to the Bilstein at the 1.1" setting?   I was going to add the 2" GM Suspension lift to my 2020 3.0L Duramax 1500 and then keep the leveling kit to give me more clearance for the 295/60R20 tires and 20x9(+0) Hostile wheels I plan on adding.  Although, if get the Bilsteins I could set the fronts at 1.1" and then keep the spacer which should give me at least 3.6" in the front. Not sure if going that high would cause me any other issues..  I'd imagine I'd have to raise the back with a block to keep a little rake though.  Do you think your TB would clear 295/60R20's with the just the stock shocks and leveling kit?

Interested in this as well. I have the 1.5” motofab.

I did. I don’t have the #’s in front of me but I ended up going with the 6112’s up front for normal Silverado, and the 5160’s in the rear sized for Trailboss. Very very pleased with the ride difference. I went with 2” Zone off-road rear block and did the GM bump stop extensions. Pleased with how everything turned out. 
 

Have not towed with this set up yet.

Ordering the 5100 front and back set for my 2021 AT4 3.0L diesel.

 

Wanting to level the truck (as much as I can) so I assume set the front to the max 1.1"?

 

I don't haul anything hardly ever, just want a better ride and control off-roading when I'm hunting coyotes and mulies.

 

Also I'll be keeping the stock 18" wheels and stock Duratrac tires until they wear out then I'll likely go to the BFG KO2, always had good luck with those in the past. I'm not sure what size I'll be able to fit under there but I guess I have time to figure that out.

I guess I decided to go a little bit further. I ordered the Cognito Upper Control Arms with their top 1" strut spacer.


My thinking is with the Bilstein 5100 set in the middle position .55" in addition to the Cognito 1", that should get me the stance and 'almost-level' that I'm looking for. And with the upgraded UCA's I should solve that angle issue at the same time. If the middle setting and the 1" top spacer aren't enough,  then I'll go to the top 1.1" setting on the Bilstein. 

 

Sounds like CV angle will be my only concern now... maybe?   :(
 

EDIT: Cognito said no-go with running the Bilstein 5100 front with their 1” top spacer. They said it would be good to go with their UCA only. FYI. 

Also the blocky Cognito UCA's will not work with stock wheels and tires according to them, they rub. But the tubular ones are supposed to be ok so that's what I went with.

2021 Sierra 1500 AT4 3.0L duramax with Bilstein 5100 set to highest level 1.1”, Cognito UCA, stock Duratrac 275/70r18 tires, stock wheels. 
 

Just wanting to show the clearance of the Cognito UCA with the stock wheel/tire setup and the CV angle

I traded in a 2019 ZR2 for a 2019 High Country.  The ZR2 was hands down the best handling truck I have ever owned.  The High Country was the worst by far.  I have replaced  the 22s wheels with 18s.  That alone was a huge improvement.  Each corner lost 18# of pure unsprung weight.  Now I have ordered a set of Bilstein rear shocks.  Hopefully I can get this thing more reasonable.  I can hardly believe this truck was released from the same engineering department.  The S2000 is my backup autocross car.  
 
>>>>
Note that I define good handling in a truck as it tracks just fine wile cornering when hitting bumps, potholes a large dips.  The rear suspension should never move side to side or shudder when hitting impacts like pot holes. This is the highspeed damping in the shock designer world. Wheel weight has a huge affect in this.  The more weight that has to get over the pot hole edge must be all controlled by the shock. The rear axle weight hurts these trucks.  The entire chassis should never give a floaty feed when hitting large dips at higher speeds.  This is defined as low speed damping to the shock engineers.  The ZR2 was simply amazing with all of this stuff.  $4000 shocks sure help.

Holy crap. 18 lbs of weight per corner? I may dump the 22s if that's the case. I always assumed the rear bounce on my truck was due to the solid rear axle. It's the only reason I partially wish I had gone with the Tahoe.

Hello, newly upgraded to the 5100's, ride quality is an incredible improvement from the Z71 rancho's. 

Question, I noticed that the mechanic didn't cut the dust boot as described in the install instructions for the front, is this anything to worry about? I could probably reach in w/ scissors and give it a rough cut. They seem fairly soft so I wouldn't expect any issues if they did occasionally get compressed a little. 

 

I scanned through the posts and searched the forum, apologies if this has been asked before. 

 

I'm on the #4 .90 in level for the 6.2 L.

I have a 6.2, and set my 5100s at the #4 slot also. I cut the boots as instructed, and once together, absolutely can not see why I did. As much as I look at them, it seems entirely unnecessary.  If I had it to do all over again, I would not have cut them.

For whatever that’s worth .

My front 5100's are getting installed later this week. I'm looking for about a 1.5" front lift. It sounds like you went with the #4 and that gives almost an inch of lift, correct?

#4 got me ~.9" yes. It was what I needed to level out the 6.2L. #6 is ~ 1.5"

Thanks for the clarification. How hard are they to change the setting once installed if I want to go up or down a notch?

You have to remove them from the strut, change the setting, and reinstall it.  It's a pain, so set it at the right height the first time, if you can.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      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.

      OCI, not when but why?

      By Grumpy Bear · Posted

      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.

      Rattle in the rear!

      By MASONV88888888 · Posted

      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.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
