Pictures of my 6.2L AT4 on stock suspension with 36inch tires, Borla Exhaust and Amber DRLs


Recommended Posts

I took some pictures of my truck few days ago, thought I'd share.

 

Tires are on 22inch rims and they're around 35.8inchs when measured using a measuring tape.

 

Borla S-type exhaust with dual exhaust tips on each side.

Sharp truck!! I too have the same rims but on a Silverado, what is the tire size on the sidewall and what kind of tires ? are they Nitto`s and is there any wheel spacers?

They appear to be Nitto Recon Grapplers.  I have never seen a GMC Sierra able to fit 35's without significant trimming, so I am very curious how you got 36" to fit.  What's the tire size on the sidewall? 

 

Very clean looking truck!

How did you do the Amber DRL's?

That's what I want to know!

 

I made a thread little more than a week ago about your truck. I had seen it in the parking lot and took a few pictures. I wanted to wait and talk to you about how you got the Amber DRLs working but I had to leave. 

 

I love the look of your truck! This is my dream truck, super sharp looking. Can you tell me a little more about your wheels and tires? When I saw it, I think you had different wheels on. I think.

 

Thank you!!

I saw that these trucks had full amber lights and wanted to use those as DRLs. I looked online and found only few options:

 

One was to bake the headlights in the oven and take them apart and replace the white DRL Led strip with yellow one. This is too much work and chances of getting it right are pretty slim. For me at least. Not to mention no more warranty on headlights.

 

Other option was to replace it with aftermarket headlights, but those are all junk and look very cheap with very dim dotted DRL LEDs.

 

I opted to design my own little circuit board that controls the function of these DRLs.

 

The circuit board I made is very small and compact, about 4x4in. The weatherproof case is about 6x6in. And for it to work you just unplug the harness from the headlight and plug this in between and you get amber DRLs which you can change with a switch in the cab.

 

It was a lot of trial and error and spent a good amount of money on versions of different PCBs that had to be printed and after a few revisions I got it working. And the OEM harness plugs were hard to find initially but lucked out and found em online.

 

I made it plug and play, because I didn't want to hack or modify any harnesses or headlights and maintain the warranty on those items. GM is notorious for voiding warranty for stupid ******. This way I can just pop these modules out before I bring it for a service.

 

What the PCB does is, when its on, the DRL signal to white LED stops and in its place the amber LEDs light up. The hard part with designing the circuit was retaining the turn signal and hazard lights functionality along with the amber DRLs. And making it all work with the turn signal feedback loop.

 

When the PCB is off, then it acts as a pass through, like its not even there. Then everything works in factory mode as GM intended.

Super nice truck!!!! Love the color and set up. I'm curious what you did you get 36" to fit as well. If you could explain what steps you took that would be awesome. I have 34.4 recon (285/55/22) and I can get the rub to stop. Thanks

Soooo…… when will you be making them and offering them up for sale?

I guess ya, if there's enough interest. I can manually make these, bu they are time consuming and parts are expensive. especially the PCBs.

 

They are cheaper to make in larger quantities, and instead of locally, they will be 1/4 of the cost if they are made in China.

 

I'm making two of these for my buddies but they're eating up the cost and labour.

Do you think it will work on the 19-21? Same plug adapters I'm assuming?

 

I think on the 19-21 Sierras the DRL and turn signals reside in separate places in the headlight. They're not similar to the new Sierras where the DRL and turn signals are in the same place.

 

The new Yukons and 24+ Sierra HDs on the other hand would probably work similar to the 22+ Sierra 1500s

In the first picture, You can see how the mudflap looks WITHOUT the metal bracket, that used to be there. The aqua color indicates where I used the screws to secure the mudflap. I also trimmed the wheel liner, indicated by the red line. This is trial and error.

Online you'll see some people just chop the plastic mudflap in half. I wanted to take out as little as possible. So after a few tries, this is what I ended up with. You can see in the first picture how it looks, it still looks like a mudflap and the bottom splash guard is still there.

For the front, same thing. The plastic piece that I cut, is only used to hold the wheel liner in place. Again, online people just cut the whole thing is half, I just cut what needed to be cut. I used one original mounting area for the screw and then used a self tapping screw at the other mark.

 

I did this a process a few times that day. I would modify and then put the tire on. I would check around and see what's rubbing when its on the ground.

 

I also took it for a drive few times and make sure there were no rubs when turning or going over bumps when the suspension is compressed.

 

Also I used this Milwaukee Oscillating tool
