So, I looked at a 2015 All Terrain 6.2 4x4 today. Sweet.....
I would want to lower it, probably 3/4 or 3/5

Looking at the normal suppliers, Ground Force, Belltech and McGaugh's,
it seems there are coverage issues for 4x4 as well as aluminum lower control arms which the new truck seems to have.

Any insight???

2" drop coils, lowering struts set a 1". Probably going to need offset bushings for the upper control arms to get the alignment right. Or swap out the aluminum arms, to run drop spindles.

I'll revive this post,
Got the truck, 2015 Gmc 4x4, it has steel lower control arm.
There is still no listings for spindles for 4x4.
Any one know anything different.

I have shackles and shock extenders if you want to bring the rear down 2"

The rear is easy, the front is the issue.

as far as i know, spindles should be the same for 07+ trucks. 2wd and 4wd are the same, except for 4wd with Al lower control arms I used belltech 2509 drop spindles on my 2012. the new 2511's on my '15 which helped correct a lot of the negative camber issues with 4"+ drop

the 2509 are listed for rwd on 2014-2015. same for 2511, rwd
Although they may " fit" a 4x4, there must be a reason the builder doesn't list the fitment.

I've had the 2509's on a gmt900 4x4 before but found the GroundForce equivalent fit better and required less alignment adjustment.

I am not fuzzy on the brands but would like to find a 4x4 listing.
Maybe I'll call them and find out what's up.

Edit...

Called Belltech, some snotty kid said they don't have 4x4 spindles
and won't be developing them. Said 4x4 spindles are completely different.

Called GroundForce and they are in prototype now and will be released 30-60 days.

Called McGaughs, guy said parts # 34050 works with steel control arms. That is the same part # 07-13 2 AND 4WD.
So, Belltech 2509 will probably work as well.

Called the suspension source. The real issue with the 2015 4x4 is that
some come with an aluminum spindle and/or alum control arm.
The alum spindle is not the same as the steel one and the older parts, Like the 24050 or 2509 do not fit.
New parts will need to be developed for the aluminum spindle.

The 2014 trucks did not come with alum spindles.

NOt sure where all that info came from but we have lifted/lowered over 300 of these trucks and trust me the parts all swap, if its steel use the older spindles if aluminum use the newer ones but there is a big difference between Mcgaughys and Belltech fyi Mcgaughys is much better

Thanx for the info.
Info came for the people that make the parts, as noted above.

Are you including 2015's with aluminum spindles as well as alum control arms.
Can you give me part numbers for older[34050??] and new style spindles.

Aluminum control arm trucks are absolutely not the same, and the spindles designed for the steel arm trucks will not work. The aluminum arm trucks use much larger ball joints; there may be room to hack the spindles designed for the steel arm trucks to fit the larger ball joints, but I wouldn't trust it on the road.
