 I have the Silverado LTZ and I'm wondering if anyone has looked into this or knowledge of replacing these antennas, with either aftermarket of other GM models that would work, without losing anything.

 

I'm still learning this truck and don't know if this antenna is specific to the model.  Wouldn't think so, but I ask anyways and my issue with mine is it's a couple inches too tall when coming in or out of my garage. Being in Florida, I have high wind brackets on my garage door and the antenna hits the bracket.  

 

Thanks in advance for any information that can be passed along.

Can use pretty much most aftermarket ones, or if your the handy type cut yours down, reattach the ball and it will just like a shorty oem antenna

I just replaced mine with a 4" Stubby. Same issue as OP...garage door height barely clears roof, and OE antenna drags.

Superior customer service from these folks. The one they sent wouldn't thread on. Either it was wrong, or as they said, there are 2 different thread patterns in use for 20's and 21's. Either way, they sent me the variant model free of charge and made the exchange super easy. Very quick to respond, quick to ship.

 

With *any* shorter antenna, your reception will be affected. Most notably, AM stations in rural areas will be hard to get. If you are in-town and mostly listen to FM, you shouldn't notice much if any loss except maybe for some distant FM stations. XM or other signals are unaffected - different antenna for those.

Excellent, thanks all! 

A little more research into the marine and ham radio industries, to see if anything applicable, before I decide.  

 

I did manage to have an old thread come up, that didn't from my original search -

I just received mine and have the same issue, glad to hear they take care of it easily.

Amazon Special. Pretty good AM/FM reception.

Which brand was this one? I may try one of the stubbies, but I've also looked at some of these taller versions.  The only wire wrapped ones I came across, was of the OE whip style.

I have a Sierra 1500. I initially tried the popular aftermarket rubberized stubby you find on Amazon. It performed fine and required a thread adapter which was included. I only kept it on for a few months because it got tired of noticing it all the time. Although it was short, the thickness of it stood out to me. Just about all of my front seat passengers would ask, "Was that always there?", referring to the "covert-stealthy stubby antenna.

 

I ended up replacing it with a shorter version of the factory antenna. It is 7 inches tall and does not require a thread adapter. Looks stock but a lot shorter. Performance of this antenna seems to be the same as the stock one. All the same stations come in fine.

 

I found it at theantennasource.com. Free shipping was quicker than I expected.

They also have 9, 12, 15, 21, 24 and 27 inch versions in black. Other sizes come in stainless.

    • 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.
