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 imagine the cold winters up here with repeated short runs in town every day for those that live and work in town and given what I have come to learn on this forum with DI engines having fuel dilution issues, and if they don't change the oil until it says to but keep driving it for a while, I bet all that is just lovely on those finicky lifters. 
    • I just did some reading and Stabilitrak is more than a what I had originally thought. It is more of a vehicle control system to help the driver in precarious situations. I thought it was only the AWD system. Now I know. So I changed the title for this thread to AWD conversion to Z71 
    • Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks
    • My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.
    • I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.
