Lifted/Leveled 2021 - Postem Up

[olyelr]

I just mounted 295/50/22 BFG’s on stock wheels. SuspensionMaxx leveling kit and only used 2 inches of the 2.5 available. Rear is stock.

Running into issues with run at slight turn when in reverse, almost to the point where it rubs on the running boards. Looked fine at tire shop. Might have to go back to 285/45/22 or bring the front up a bit.

Any thoughts?

Just do a little trimmin!

Looks great !

I’m surprised as your tires are very close to the stock Z71/AT4 size. I’m running a 3/4” taller tire (315/70R17) with slightly less offset at stock ride height. I also have the power running boards. I only rub at entry / exit ride height (approximately 2” lower than normal).

Based on your description, I suspect you haven’t done anything to the wheel liner, and you’re rubbing the liner just above the running board. There is a bracket behind the liner, just above the running board, held in place by 4 bolts. Remove the bracket the tie the liner back to the frame. I used a self tapping screw into the small divot in the frame. Once done, it’s completely unnoticeable from outside and you would have to be quite familiar with a Tahoe/Yukon wheel liner to tell, even with the tire removed. Sorry but I don’t have any pictures of my mod. There were several good photos a few posts back showing behind the wheel liner and the Westcott Design YouTube channel has several videos on their fender liner kit. Strictly speaking the kit isn’t necessary but should make the mod even easier.

Doesn’t look like a 21-up to me.

Hes got the prior generation…i think the newer ones have more space in the wheel wells. Also, those older models had smaller tires.

I see that now. I may have been half asleep and looking at a tiny image on my phone last night. I also assumed I was in the ‘21+ forum as that’s all I have experience with.

View attachment 419311Finally after trying to decide what to go with. Thanks to all of you who have posted their setup. Really helped me decide what to do lol
3.5” rc lift
20” Fuel rebels +1mm
Wrapped in ridge grapplers 35x12.50

Was trimming/cutting pretty extreme for the 35’s? I’m on a 3” readylift and temptation to move up to 35’s is there. Speedometer 2-3 mph low?

There was minor plastic trimming/pulling the wheel liner back some to take away rubbing. I have no rub at all now at full turns. This was with the 3.5” RC too. As far as the speedo I haven’t checked how far it’s off but my guess would be that it possibly is off a tad now. Anyone know how I can check on that?

Thanks for the info! Back of my front fenders has some space, did the wescott pull backs, but front of front fenders was rubbing with 295 60 20’s even after a little rework. So I’d have more to do there with 35’s.

I use the Waze app to check speedometer. Had an mph app too which seemed the same as Waze . Not sure how accurate the gps apps are for speed, but from what I can tell they’re darn close to actual.

 

[jgraves]

I was also going to suggest Waze. I think google or apple maps also report speed on some instances (maybe when navigation is active). In general GPS is very accurate for speed measurement. I’ve seen some short duration inconsistencies with speed reported by navigational GPS which a suspect is due to a lower sampling / refresh rate, but on straight, level highway at constant speed and considering an average, then should provide a very accurate speed.

My AT4 speedo reads 2-3% slow with 315/70R17. I don’t recall checking with the stock tires and the stock AT4/Z71 tires are a little taller than the other trim levels which may be factored into the speedo programming.

I really appreciate the response. I’m going to take a look in the morning and will post a few more pics of the main issue. I’ve been looking at replacement tires/sizes and would rather not change at this point.

Here’s a couple photos of the area in question. You were right on about the screws and placement of rub. Gonna get to work shortly.

I think you’ll get more relevant info in the 2015-2020 section. The 21-up are way different.

On my 24 Yukon AT4. I don't think I need 2.5" lift. I wonder how the RC2.5 does if I leave out the preload spacers? I like the control arms on the Ready lift 3" as they look more durable, but I think it will go higher than I want.

Where are people finding the best prices on suspension and wheels?

RC has a 2" with strut spacers, and a 3.5" with strut and preload spacers.
You're asking if you can get the 3.5" but leave out the preload spacers, and only used the strut spacers and UCA's?

 

[djnice]

Yes, but since the AT4 is mag ride, supposedly I have to go with the 2.5". They are probably different so that the strut spacers accomdate the wiring. Maybe I will like the 2.5. I am a little worried it will be too nose high so maybe I could leave out the front preload spacers?

Looking at the photos of the 3.5 and 2.5 side by side I can see the differences. I guess my main two concerns is what is the actual resulting lift in inches and what is the height difference front to rear.

The second less critical issue is the Ready lift versus Rough country UCA's. Is one much better than the other?

 

[djnice]

Actually, I think this answers my question. Wish it was on an AT4, but it appears to have lifted the front and rear equally.

Gotcha, didn’t catch the Magneride part. My experience is with the 2” rc and 3” readylift, and I can say both of those are nose high on my z71 (more so with the RC). Pics I’ve seen show the same for the 3.5. With that said, trim packages other than z71 and at4 sit level or even a bit rear high. So to my eye there’s a bit of a difference in stock form between their struts.

The 2.5 I have no experience so won’t comment.

Agree the readylift UCA’s look heavier duty than RC’s, but can’t say if they’re more reliable (haven’t heard of either failing).

www.tahoeyukonforum.com

RC says it’s only for mag ride but that’s not true. You can do the 2” spacer kit with no mag ride effect. The struts don’t even know the height has changed on the vehicle. I had a 2” and changed to 2.5 because I had issues with the lift (Traxda). Also mine has probably a half inch raise in the back vs the front. Not perfect but close. 2” looks to level things perfectly though.

 

[djnice]

@Rayse, do you think the lift raised the rear more or was the stock Denali already a half inch high in the rear?

After using the Waze app, it was indeed off ~1-2mph. So my Speedo said 68 but Waze said 70 lol
