I bought my 2013 ccsb Sierra about a year ago and it was already lowered. Going off of measurements that I've taken from stock looking trucks around town, my truck is lowered 2"/4" with just springs in the front and a flip kit in the rear. I'm trying to figure out what brand of lowering kit it has. I've contacted a couple of manufacturers, but no one will claim it! ; -) Any help would be greatly appreciated!

That’s stock springs on stock struts, factory barcode.

But drop spindles.

And a flip kick in the rear so way over “4.

Ok, thanks fir the info guys. I thought most rear flip kits were 4” drops but I do still have the factory hangers, so maybe it is 5”.
As for the front- All of the aftermarket dropped spindles that I’ve seen online are powder coated. My spindles are raw steel so I assumed that they were stock. I’ll see if I can get a better pic of the spindle to post on here.
No one recognizes the powder coated rear flip kits parts though? I’m trying to figure out the brand.

Jack,
I know that they’re not Belltech (I wish), but I thought that they could be DJM. DJM’s parts used to have a silver wrinkle powder coat but they have had a note on their website for over a year now saying that their parts are now black. They have not updated their pictures, so I don’t know if they are a smooth or wrinkle black like my parts are.
Are there any pictures of your truck on the forum? I’m curious as to what your 3/5 drop looks like. Do you know what your ride height is? Mine measures 19” F and 19 1/4” R measuring from the fender lip to the center of the axle.

Ok, I found your showcase. Nice truck, I love the color! Our gap in the front looks about the same but my rear is definantly not as low as yours.

Daly, I’m planning on flushing my brakes tomorrow, so I’ll take a closer look at the spindles. I’m pretty sure that they don’t have any markings on them but I’ll check them again and maybe take some pics. Thanks.

Thanks Jack, I’ll check the rear hangers tomorrow as well.
I found another pic of the front that sort of shows the spindle. I thought maybe someone could tell if it looked lowered or factory

Took some better pics of my rear hangers today. My hangers do have 8 holes and they are mounted using the lower holes, adjusting the hangers up, which Should give me the most drop. But I also noticed that the driver side hanger had a hole punched through the barcode label above where the shackle was bolted up, so I should be able to move the shackle to that mounting hole and lower the rear another inch if I want to.

I’m perplexed by the front,everything looks stock in the front I think, except for the barcode tag on the spring, because both the rear hangers and leaf spring pad mounts have barcodes on them also. The front spindle is definitely stock because I finally found a pic online of a used factory that matches mine down to the stamped numbers on it. I’ll attach a pic but I don’t think that it will help much.

Yes, the hanger is mounted for the max drop, but it looks like I might be able to move the shackle up in the hanger to get another inch maybe. Do you think that you’ll be able to measure your ride height Jack?

Btw-I just googled the part number on the barcode of the front spring and it comes up as a factory spring, so I don’t know how the front end has been lowered.

You’re right, it is mounted underneath, but it looks like that is the factory location.

I’ll take a closer look at it tomorrow.
