Mine just showed up VIA FedEx, super fast shipping and a nice looking product. I called around, most places wanted around a $100 to change them and another $45 for a alignment. Having them installed Wednesday at 2:30.. Thanks to this forum I got a better price than I first anticipated, I hope its worth $$$ West Virginia is good testing grounds so Ill do a little write-up after.. Thanks Again

$100 for install and $45 alignment is a hell of a deal

btw, mine came in yesterday, but i dont have time to do anything with it yet.

Installed the rear 5100's today. Short test ride afterward. Smoothed out some bumps noticibly. This is while it was still on the jacks. Can't wait to install fronts now.

Just had mine put on front/rear.....rides amazing.   Update....the best comparison I can make is that the 5100s ride like factory autoride shocks on my denali....always composed. Several large spee

The rear shocks don't add any height. They are only shocks.   The front shocks accommodate the upper and lower OEM spring pad. The lower spring pad register location is controlled by a snap ring wh

I am getting mine installed on Monday by the dealer. Anything else I need to look out for other than boot down on the back? Can you get away with just a front end alignment?

You got it...boot down for the back and my dealer recommended a front end alignment (I installed the rear and dealer installed the front).

May I asked what your dealer charged for the install and alignment?

 

Thank you

Well I got them installed today. And to be honest... it was a $650 dollar mistake on my part. I should have never messed with what I had. The new shocks may handle the bad bumps maybe a little better... but defiantly not worth the cost. Actually seems like everything else may be a little harsher, but the bad bumps..

 

A side note.. they did have keep my 2in level installed. Something about the top bolts were cut when the level was installed a year ago. Anyway... instead of removing the level, and extending the shocks out to max 1.8 in.... they left the level in place and keep the shocks at the "factory" stock adjustment..... no extension.

Not sure which way would give the best ride.. as I have heard extending the shocks to max 1.8in can also make for a a harsh ride.

 

Anyway.. the whole deal was a waste of 4+ hours and $650 bucks.. in my opinion....

Damn sorry to hear that man. I would imagine the level on there is the culprit to some of the dislike. I'm just guessing though as I don't have either installed on mine.

Yes, I'm sure the level isn't helping ... but is the level ( with shocks set at stock height) a lot worse than having NO level and the shocks fully extended?? that's the million dollar question...

GMC-AT - if you had factory Ranchos then it may not be that much of a improvement. I changed my rear shocks over to the Bilsteins Saturday at around 13600 miles, HUGE Improvement!! If the fronts have that much of a effect than to me its gonna be well worth the money spent. My truck had the plain black shocks and one (left Rear) extended slower than right rear but both still functioned properly as far as I could tell. I put SkyJackers on my 08 Silverado and it was one of the best upgrades I made to that truck. Guys, shop around, local tire shops or body shops can do this cheaper than the Stealerships can. Check out this video, it explains a lot about this subject.

These shocks have been explained many times on this forum so maybe I'm just dense, but I don't see how their method of changing the spring seat location is really any different that using a spring pre-load spacer? It seems that it is doing the exact same thing once you raise it above the stock setting, its just doing it from the bottom instead of the top.

There is added stroke for the travel of the shock itself eliminating pre-load. Edited by henrypbui

I understand that they may compensate for the longer stroke of the higher setting, but I dont see how it is possible that moving the spring seat up wouldn't be adding pre-load. I'm not saying your wrong, I just dont see how its possible. Moving the spring seat up has to compress the spring (unless I'm missing something) which is pre-load as I understand it.

There is more travel for the piston to go up to compensate for the lost travel of moving up the spring perch. It does not preload the springs since the piston itself extends that much more out, and the only "pre-load" would be from the weight of the truck itself.

Ok I went back and looked at them closer and I get it now, I was looking at it from the wrong perspective.

 

So when folks complain about the stiffer ride at the top setting, this is being caused by the increased angles which decreases the leverage on the suspension, correct?

That would have to do with the valving of the strut itself. Without it being adjustable, unless if Bilstein optimized the valving for that height setting, it will suffer a slight bit from where their optimal height would be. I would have to guess it is set at the OEM height.

      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.
