4" ReadyLift with stock wheels/tires.

 

I can't recommend it though....CV angles are too great resulting in noise and vibration.  Mine started immediately after install and is getting worse.  ReadyLift says they are within "safe tolerance" but I cannot ignore the noise and rumbling it's doing.  I'm taking it off this weekend and ReadyLift is giving me my money back.  I'm just putting a set of 2" level struts on it and calling it a day.

I think this is a more widespread problem than they think because most folks just chalk it up to tire noise.  I'm on stock Bridgestones so I hear and feel every little thing the truck is doing.

You also have to wonder why GM would install longer CV axles on their TB/AT4's with the 2' lift?

2" lift. 2' would require seriously long CVs. LOL

This is why this is such a great website. I have a 2 inch level and was about to order the 4 inch because your truck looks so good. Thanks for the info.

I put a Readylift 2” level and swapped out the 2” rear block for a 3” block on my AT4. So I have a total of 4” in the front and 3” in the rear.  I have not had any issues with noise or vibrations.  Very pleased with it so far.

Yes, because you already have the longer and/or beefier CV's.

Hey I know im a few years late however I didn't find much when I searched for my build so I figured I would post 

2021 Silverado Z71 RST

4in BDS coil over lift

OEM 18in wheels (came with the truck from dealership)

35x12.5x18 Nitto Ridge Grappler Tires 

I ran 2in adapters to avoid tie rod interference

Bumping this topic and will follow up with it in January/February. Just ordered a 2025 RST diesel 4WD, I do not want to do the 6" kits. I am in love with how the ReadyLIFT 4" SST Kit sits so I am going to make it work. After doing extensive research, CV angles are what's messing people up so my solution, based on online research, is upgrading the CV axles to the Trailboss/Z71 CVs which are longer than the normal 4wd CVs. ReadyLIFT makes a 2.75" Lift for Trailboss/AT4 trucks that give the truck a total of 4.5-6" of lift, so if those CVs can do it, I dont see why they can't do it for a 4" lift on a regular 4WD. I cannot confirm yet if this is the fix as the truck was recently ordered and expected to arrive in December. If any other person has gone through this testing of the trailboss CVs, let me know. More to come.

    • 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.
