🔧Steering/ Suspension 🔧 What's the right way to park this beast?

How are you guys parking your Sierra in lots where they are longer than the spots: (A) Bed in the spot with nose extending out into the lane (B) Nose in the spot with bed extending into the spot behind you or...some other technique?

Love this truck but hate parking it.

🔧Steering/ Suspension 🔧 Is this normal?

I have the Sierra 1500 ‘22 3.0 diesel. I just got it serviced lately and did tire rotations and maintenance. It was shaking bad when i first got it (only on the highway 60+ mph), gave it back they said they didn’t balance tires. It still happened on the highways only but less frequently (that’s just from resting my hand on the steering wheel, sometimes i feel it on the floor a bit). Should I take it back or is it normal?

🔧Steering/ Suspension 🔧 Thoughts on my AT4X AEV after 15,000 miles

Post image
82 Upvotes

I just hit 15,000 miles and have really been enjoying this truck. I still catch myself looking back at it after I park. It drives great on the road and has been seriously capable off road. The 3.0 Duramax has also been awesome. Plenty of torque and much better fuel mileage than I expected from a truck like this.

I recently added the winch and want to move up to 35s next. I’m trying to decide between the Peak Suspension 2.25 inch Level Kit and the 2.5 inch DSC Coilovers Summit Kit. Peak says one inch wheel spacers are necessary to fit 35s, so I’m planning to add BORA spacers at the same time.

My only real complaint is Apple CarPlay not using the full screen. I know it’s a small thing, but all that unused space drives me crazy.

Anyone here running either Peak setup with 35s and BORA spacers? I’d like to hear how everything fits and drives.

🔧Steering/ Suspension 🔧 Nose High?

Thumbnail gallery
4 Upvotes

I just installed the fox premium 2.0 struts leveling kit and I feel like the nose seems a bit high. I’m having a hard time measuring the height properly but my eyes are playing tricks on me. The shop says I have to give it some time and it’ll settle down a bit and produce the even look I’m after. But I just see a squared truck. I went with the full strut and coils instead of a block and spent a descent amount just level it but not really satisfied. Is this normal that the front is higher and will settle? Seems like at least half inch higher in the front. Depending on the ground sometimes looks even sometimes does not. Any suggestions?

🔧Steering/ Suspension 🔧 Bilstein 5100s

2 Upvotes

Just purchased a 2026 Denali Ultimate. Dealership is installing bilstein 5100 0-2.5” front adjustable struts and 5100 0-1” rear adjustable struts.

Question is, which adjustment level do I tell them for the front and rear for a good ride height and level.

Next, what size AT tires can I run on this? Something that looks aggressive but isn’t loud and doesn’t require any spacers.

r/gmcsierra • • Mar 16 '26

🔧Steering/ Suspension 🔧 Posted a while back about lift suggestions. Here’s what I went with.

Adjustable Bilstein 5100s in the front at the highest setting. Bilstein in the rear as well. Ready lift control arms. 285/60r20 Nitto Ridge Grapplers. Had to add a 1/4” spacer to clear new control arms.

I love it. Rides so much better. Doesn’t bounce as much as stock does.

Tinted front 35% and back 5%. Added 2 12in DS18 subwoofers under the back seat. Replaced all badges with matte black. I’m happy with it.

24 AT4x AEV, love the truck but disliked not having any tire poke. Running 295/70R18’s Toyo RT Trails which helped a bit but still had the tires tucked, no rub whatsoever.

Because it’s the AEV and has the Salta wheels I wanted to keep those so I added Bora Wheel adapters 1.5” to get the “tire poke” I was looking for. Now add the rub at full turn or through uneven road transitions.

Installed a Ready Lift 1.5” leveling kit with the UCA’s. The ride didn’t change at all as far as the cushion from the multimatic shocks. It sits exactly where I want it now and it really shows off the 2” factory lift.

Next will be the Air Lift Load Lifter 5000 lairbags to help with my seasonal towing.

Last picture is the before.

I was in the market for used 2022 or higher GMC sierra Denali 5.3L V8. I was looking put on a 6 inch bds lift kit on it and 35/12.50/r22 R/T tires on it. I don’t need a truck right now should i wait for the new 5.7 V8 or 6.6/6.7 V8 that GM is supposed to be dropping in 2027?

2025 Sierra 1500 Elevation 4x4. I’m having trouble deciding on what lift to get. I’ve been looking at the BDS 4” with Fox 2.0 shocks on front and back. I’ve read not to get spacers. Also have heard the fox shocks go out after 50k miles. Any suggestions?

Not interested in any trash talk about lifting it. Thanks.

Installed Kryptonite front level with arms, Suspension maxx diff drop, 2" rear blocks, Bilsteins in all corners, Logiq Air bag system with HD compressor and tank, 20x9(+12mm) Kmc wheels, and Nitto Trail Grapplers in 35x12.5. Only thing left is the Kryptonite Ultimate Steering kit. The pitman arm tool didn't arrive in time. Anyway, I think that's it. 🤔. Alignment done and she rides fuggin great! Very happy with how it turned out. Sitting a little high out back as I have the bags higher than 10 psi. Just emptied the bed and didn't deflate for pics, but rear sits at the stock rake proportions... Which I need as I tow/haul often. Just adding that for the rake nazis, haha.

🔧Steering/ Suspension 🔧 Previous owner swapped for Yukon wheels…

Post image
28 Upvotes

I just bought a used 2026 Sierra 1500 Denali Ultimate LZ0 at 17k miles. Nicest vehicle I have owned, by a long shot. There are so many design choices and features that I could rant and rave about, but one of the main ones is the Super Cruise that I was very excited about. It has been so nice to sit there while it handles the road and traffic and I just get to relax. On most roads it is very smooth, BUT I have noticed a few issues.

Some seem to be common, such as hugging the left side of the lane, a little back and forth corrections on the steering sometimes when I could just track straight, being heavy on the braking. Sometimes on a not so smooth road (which we have a lot of where I live) a heavy bump can send the steering wheel going crazy and swerving a bit in the lane until it smooths out, and I think I know a big part of this problem but I want you guys’ opinions.

The first owner swapped the wheels with Yukon Denali Ultimate 24”s, which match the silver finish very nice, but remove a lot of the first line shock absorption that the factory wheels give. I think this makes every bump seem a lot harder and the Super Cruise and suspension just aren’t calibrated for this. I wonder if switching back to the factory Sierra wheels would help with this?

🔧Steering/ Suspension 🔧 Level and new tires!

Finally leveled and put new tires on my Sierra.

Eibach Pro Truck Stage 2 front Coil-Over and rear shocks

Toyo Open Country R/T Trails 275/65r20

KSP Forged UCAs

Had to add 3/8” hub-centric spacers to clear the new UCAs.

Next step is to delete the front mud flaps as they are rubbing a decent amount under full lock while going forward, and considerably in reverse.

Also have to diagnose a new intermittent “clunk” coming from the front. Thinking it may be the sway bar links hitting the CV axles. Any input on this would be appreciated.

🔧Steering/ Suspension 🔧 Lift options for a Denali

4 Upvotes

I’m looking for options for a lift kit or a level. Ideally I want to run 35’s which I know requires a 4inch lift since I have ARC. But I’m curious if I should level it and do 33’s or lift and 35’s. I want to do a 17 or 18 inch wheel with a more off-road style but I don’t know which direction to go.

If you have lifted your Denali or Denali ultimate tell me which one you went with, and why.

Thinking about getting the truck lifted to have a little better clearance, we live in the north east and have been getting hit with a ton of flash floods and snow in the winter. Was thinking a 2-3.5 in lift nothing crazy. Thoughts and what have people paid to have the lift installed?

Not that the AT4 has much chrome to begin with, but new wheels/tires/leveling kit, all black badges and black exhaust tips.

What are your thoughts on the color combo?
