Yes. Measure it before and after tires to middle fender wells
Now 39” front and 41” rear
Not sure why some trucks have more rake. Mine just sits half inch lower than yours so I’m happy. I’m worried with the 1.1” leveling it might raise the front too much.
 

I only used the front ones. They seem to give a lot more room. You see I screwed the innner fender liner in several spots . Getting the liner in the fender oem hole was a pain by myself since it wants to pull away from hole when pushing new plastic piece. Made a slit in liner and helped. Also caulked behind it to liner to keep dirt from getting behind.
Does the job ,didn’t even try to run without ,figured just hack off fender metal to make sure would fit. Mini cutting wheel was best way to cut metal and liner.
Painted metal with POR15 to keep from rusting
 

Called GM roadside assistance and had them tow my truck from my driveway to the dealership since it won't start. We'll see where they can get with it. I tried charging the battery fully, disconnecting it and resetting the system, I looked all over for loose / broken connectors / wires. Nothing. Just rolls, no fire. And I'm also getting the service def system message for some reason. I'm really hoping it's something simple as camping season is around the corner. On a positive note, I got by bracket made for my air control valve, for whenever I get the truck back.

Some real light modifications this week. One of the 6.6L V8 tags was coming off. So I ordered some custom replacements. Installed some stake pocket plugs. Then finally had some good spring weather so gave the Blue Brute it's first good clean up and speed wax.

Great pictures, can you please elaborate on the installation? There's a lot of conflicting information on these kits. Is this just a kit for leveling the front and rear?
The kit is just for leveling out the front to match or to have a small gap compared to the rear. The rear shocks will not lift a vehicle!

On the installation it's long list of things you have to do. Remove lower sway bar end link nut, removing the lower and upper strut bolts then removing the strut assembly. After that loosen the UCA ball joint nut and then loosen and remove the UCA bolts, then remove the ball joint nut and remove the arm. Assembly is just reverse. I'm about to get my struts hopefully by Tuesday next week and installing them on the weekend. Hope we hear from Hydorolling for some pointers..
 

Got a call from the dealership. Battery has a dead cell that needs replaced (for $500). I said no thanks. Went downtown and bought an agm for $240 and very politely told them to install it for free. Or pull it outside and I'll do it after work. Also, some sort of wiring issue at the ecu. They said it will take 2 hours to diagnose and fix at their shop rate. I gave them the details on my extended warranty. Hope that will take care of it, but who knows. They haven't even gotten to the other multitude of check engine lights or coolant control valve issues yet.
 

The saga continues. Got a call from the dealership. Truck runs again. Apparently the battery I bought yesterday wasn't the right one. So they put their battery in at my cost ($240 vs $500), so I could return my battery. Absolutely baffling how their 500 dollar battery yesterday only cost $240 today, but I digress. And they fixed the wiring issue in the ecu at shop rate. Apparently, that wasn't covered under the warranty, powertrain or extended. So all in, a little over $500 out of pocket. Kid behind the counter said they cleared the check engine lights and hopefully they won't come back on. I told him I'm sure they will. No delivery timeline on a ccv in sight. I love this truck, but I do have my eye on a 24 elevation with the new lzo with half the mileage. I'm gonna give this at4 another chance, but my patience is dwindling.
