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.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      4 low is really nice on steep boat ramps.

      Gas Prices

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
