Also, measure from the middle of your wheel cap to the fender lip.  Then tire size won't skew readings in comparison to other trucks.

Thanks, will do. Starting to think my guy messed up... I should have measured before hand...

Try and search or maybe someone can chime in on stock fender height on Z71 suspension. I have Z60 suspension.

 

You would see the lower rings below the spring seat if set at max. Like others have said, always measure from flat surface and center of wheel. I hate to say it, but think you are at stock setting, maybe 2. 

 

The 3" of rake is additional confirmation using rough #'s. If you bumped the back up by 3/4 , assuming 2 1/2 " stock rake , you would be right around  1 " of rake at max setting of +1.85 up front.  Hopefully you have some written documentation on what setting you requested.

Just to chime in, i measured my 2016 Z71 before bringing it in and i had almost exactly 2.5" of rake bone stock. Also, my shocks came set at the 1st (lowest) setting from the factory so i went ahead and moved the ring up to the highest rung before bringing it in. Didn't want to have to bring it back if they forgot to make the change! Curious what your install charge was? I was quoted $320 for install, front end alignment and tire rotation for good measure. Not cheap but the shop specializes in suspensions so I know it will be done right.

Really nice price point there.  Mine was 415 out the door with my guy.

yeah, well got a call from the shop about noon today and that $320 turned into $450 because he initially thought he was just replacing the strut ASSEMBLY, not disassembling it to swap out the shock. I have no idea how that little detail got overlooked but he said it added about half an hour per side. I can see 30 minutes to compress the spring, disassemble it, swap out the shock, get everything back into place and reinstall it. But an hour per side just to get the strut assembly out? I'd actually originally planned to pull them out myself and bring them into the shop but decided I didn't want to kill a weekend and be without my truck so figured I'd have them do it and eat the labor costs (we have tons of things to do around the house every weekend so time is precious). Maybe it's more complicated than I imagined. It's not anything I've ever done before and I don't have a fancy lift or air tools so I'm sure it would have taken me awhile to do but in hind sight, to save $200 in labor I should have just dove in! I'm really anxious to see how different the ride quality is. I'm also glad I decided to do the rears myself. That should be easy. Turned out to be a pretty expensive front end level, but at least the shocks are much higher quality (and adjustable) and hopefully the CV angles are closer to stock than they would be with a spacer. After I absorb this bill, my next adventure will be bigger tires (and I can start following another gm-trucks thread)!

Sierra Dan, I don't know anything about the front ones. I only purchased rear ones and they had no adjustments. Cheers

I posted this on the 6112 install thread, but will paste it here for others following this thread. I was desperate for measurements on 6112 prior to install. Hope it helps others..

 

Just returned from the shop that installed my 6112's up front and 5100's in rear.

 

I have the Z60 suspension and liked it. Truck is basically new and has 4k miles on it. 

 

I was originally going to set at max setting (4) and install a 2" block in the back to achieve a level. I talked to the installer awhile before dropping it off and he asked what I was hoping to achieve. Basically told him this is part of a process to allow larger wheels and also not sacrifice ride quality, hopefully improve. He immediately asked how big of tire and I told him 275/60/20. I'm on stock 20" rims and 275/55/20 tires. He rec'd setting the front adjustables to third setting and leave the stock blocks in back. Told me I would look level and should have a rake of right around 1". After changing my mind multiple times, I went with the 3rd setting and eliminated swapping out the stock rear blocks. 

 

First impression. I pulled up and saw my truck out front. It pretty much looked the same. Stock wheels and rims still on.  Only since I've been measuring and focused on wheels, tires, could I tell that there was a little more open space in the front wheel well. Most people would never notice. Truck appeared level.

 

I paid and jumped in the truck to head home. Immediately noticed my hood was a little higher, but nothing dramatic. I had about a 15 mile ride home and I took all the back roads back and they are in poor condition. I don't know if it was in my head, but they seemed a little smoother. I could feel the potholes, but only once and the suspension quickly recovered. I was moving at a good clip to test the changes and came around a corner where a car was turning and had to hit the brakes pretty hard. Immediately noticed brake drive was gone. I know the suspension is firmer, but only say that because I could hear a slight rattle near glove box, passenger seat. I never drive without tunes playing (had them off) and that might be some of it. Also had all the oem coils and struts in back, parts on passenger floor and my locking lug nut piece was still on a lanyard in the cup holder. I'll clean things up later, but suspect the passenger seat rattle might be due to stiffer ride, possibly loose stuff clanking. Time will tell. 

 

Bottom line, I noticed two big changes. #1 The truck stays level in turns at speed. #2 Brake dive dramatically decreased. I felt like I could drive faster on rough roads and the truck was tracking straight after bumps. 

 

Now to the measurements. 

 

I dropped the Truck off and measured everything before the swap. 

 

Front center point on wheel well was 36 3/4 stock, rear was 39 1/4 = 2 1/2" of rake

 

Bilstein 6112 with Bilstein 5100 in rear

 

Front center point on wheel well 38 1/4, rear unchanged at 39 1/4 = 1" rake. 

 

So, I gained a hair over what I expected. It could settle a bit, we'll see. Bottom line right after install I gained 1 1/2" up front on 3rd setting.

 

I'm happy with the ride, but coming off new shocks and coils , it wasn't huge. It certainly didn't get rougher or unpleasant. 

 

Next, I'll be looking hard at rims and tires to complete this project. Then, what I want the most is a tune. The owner and another mechanic both said they love my exhaust and wanted to know what model I had. I laughed and said it's a Borla Atak, really barks at start up when cold. They agreed and said they all really liked it except one guy. I wasn't sure what was so funny till they whispered and pointed to another mechanic. I looked and he had a Tshirt on with coffee stains up front. I guess he was standing next to it early am sipping coffee and it really startled him when it started and he split hot joe all over his white t-shirt. 

 

I can also confirm that the Bilstein 6112's at the third setting will show 2 rings exposed below the spring cup. 

 

Pretty happy so far and really looking forward to putting bigger tires and new rims on next. I'll have to drive it on the highway next to see what changed.

Great review Jeff. Thank you for sharing.

Hit a railroad crossing soon and you should notice a huge improvement over the stock suspension you ditched.

It will take a little time getting used to the firmer planted feeling but you will not regret the swap for sure :thumbs:

Hopefully the $400 increase with 6112s over 5100s will yield further benefits down the road.

Looks like your guy messed up, you should be able to see rings underneath if it was at the top setting. That looks like the stock setting, which would explain the large amount of rake

He said he went with 3rd setting not the highest.

Hello, early next week I should be receiving my eibach kit (2.5” with the springs) for my Silverado 2016. do you guys think I can fit 33x12.5 r18 nitros ridge grapplers or just stay at the 285/65 ?

Should fit just fine depending on the offset

I'd be surprised if that fit without some trimming. Its the width that usually gets you and thats a wide tire. I'm looking at rims and tires now also. Do you have stock rims? I don't know offset on stock 18" rims. Whats your current offset? That tire will move over .65" closer to suspension + frame. 2016 models started with the Stamped Steel UCA's. Do you have those or aftermkt UCA's? 

 

You might get away with a 275/70/18, maybe even 295/65/18. Both are basically 33" high and the first tire is 10.8 " followed by 11.6 " width  on 295. 

 

I'm guessing you will rub UCA if you have stamped steel, also will hit the lower rear corner on front wheel well where I've seen  guys cut and slap a plate on there. Zone makes one among others. If your not swapping rims, try a local shop and ask for a test fit first.

    • Hello hello looking forward to expanding my knowledge of the 2026 2500 HD that I just bought.   Truck has 3500 miles on it four-wheel-drive crew cab and I’m about to put a 6 1/2 inch BDS lift on it 18 x 10 -25 offset with 37’s   Already have the wheels and tires just waiting on the lift install in about three weeks   Question what surprises am I not gonna be happy with?  I’m not new to lifted trucks so I know that acceleration towing gas mileage all that is affected..   Question is those of you that have this truck this powertrain with a 10 speed Allison and have done the mods that I’m doing,,, how bad is it? Is that Allison constantly gonna be hunting for the right gear to go into? And what about towing, acceleration, fuel consumption as mentioned?    Lastly how come I can’t find any ring pinion gear set up for these axles and when could I expect to see them?   I apologize if there’s any typos I’m doing speech to text on my iPhone.    
    • I've got a 2013 2500 6.0L Flexfuel. Drove the truck earlier today with no issues. Went to run an errand tonight and noticed key fob wouldn't work. Figured battery was dead, so replaced fob batter. Still wasn't working. Grabbed my other set of keys with the other fob and that one wasn't working either. So I manually unlock truck and insert key. Interior lights come on, dashboard lights up, turn key and truck starts. Turn truck off, like a moron, and try starting again. This time no crank, no click, no nothing. Lights still come on and dash lights up, but now I'm getting a service 4wheel drive, service tire monitor, etc. Check voltage on battery and Im showing 12.2v. Throw my battery charger on it and give it 15 mins and try starting again. But still no crank no start. Decide maybe its a bad battery, run to autozone grab a new one and put it in. Same issue. Disconnect battery and let it sit for 15 mins. Try again and still nothing. I had managed to roll the windows down earlier as its a humid night, but now I can't get them to roll up. Power locks are also not working now. Then randomly I try the key again, and it fires right up. Immediately I roll up the windows as we have nothing but rain forecast this week. I shut it back off wait 30 seconds and start up again. Worked a 2nd time. So turn it off, start putting things back together. Try one more time, and back to no crank no start. And now the car alarm starts going off. Had to disconnect battery and leave it that way for the night as I don't think my neighbors would appreciate my alarm going off again tonight. Any thoughts or help would be appreciated. 
    • No one will care for you like you care for you. Do what you can for as long as you can. IMHO of course. 
    • How about them NICKS!!! 
    • Hi there.  Long time lurker, first post.    i have read the previous posts regarding the water ingress problem with this emblem.  I bought my 1500 SLT the  summer of 2025 new and after reading the MANY problems with these emblems failing I decided to install one anyways.  As per a YouTube video, I sealed ( or tried to) this sign with silicone sealant around the outer perimeter joint and the holes that were already somewhat sealed on the rear plate of the emblem.  And installed the connector assembly using dielectric grease on the connectors. The installation looked great and worked well for about 4 months……then FAILURE.  Grrrrrr…… I live in the great white north and wash my truck weekly in an automatic car wash  to keep the salt off.  Let me tell you that removing the old, failed emblem is a whole different animal than removing the OEM individual letters without removing the grill assembly. Mainly because the illuminated logo is built differently than the original letters which  you can remove the red surface lettering with a knife or some kind of blade which gives access to the tabs which hold the logo onto the grill. So I had to essentially destroyed the old emblem to remove it. Doing so killed my chance of doing somekind of autopsy on the failed , old logo.  But there was plenty of water inside when I ripped it apart.  Prior to installing the new assembly I tried it with the old harness and it works fine.   Does anyone have any insight as to where the water is getting into this emblem? I intend to seal the new logo with slow curing epoxy this time around using a syringe.  I think this newer emblem may be an updated unit which I hope GM got the vendor to fix. It has an October 2025 date on it.    If this one  fails,  I am just going to revert back to the non-illuminated letters….AFTER PULLING THE GRILL.    Any thoughts on sealing with epoxy would be appreciated. Thx!   Doug
