We just finished up installing a 7.5" rough country lift on this 2015 GMC Denali 2500HD. Tires are 37x13.50 Toyo M/T on 20x10 Fuel Maverick wheels with -12 offset. I'm very pleased with the quality of the 7.5" Rcx kit, but it really needs a smaller rear lift block. The kit comes with a 5", but I'd like to see it come with a 4". The crossmembers drop the control arms down 6", and the diff is dropped 5" which results in the torsion being adjusted up 1.5" to net 7.5" lift. The kit rides great, but it could be adjusted down to 6" if you wanted a plusher ride. The 2015 seen to have much more fender clearance, it's not even close to the back of the front fender. However, we had to raise the front bumper about 0.5" to gain additional clearance. The bumper brackets are slotted from the factory so it's as easy as loosening them and repositioning. The valence was also removed and some very slight inner fender liner trimming needed to be done.

looka great, love to see what needed to be trimmed on the inner fender

I don't have any pics of that, but it was the plastic/felt inner liner. It wasn't much maybe the bottom 2" or so.

I just tried to take your advice and raise the front bumper up a tad but I was having a hard time. Which bolts do I have to loosen in order to adjust up?

 

[bigredz]

There are 8 bolts( 4 per side) that hold the bracket to the frame. The side brackets will need to be loosened too. You'll have to remove the grill to get to the bolts

:sparta:

2014 and 2015 HD are different body styles :whip:

 

[Will_i_am]

Tint and different wheels :humping:

So when are going to stop with the bodystyle acronyms??

OOBS
OBS
NBS
NNBS
New NNBS.....

Since GM likes to change the bodystyles every 3 years I guess we could do this:

NBS
2NBS
3NBS
4NBS.....

Otherwise we will be all like NNNNNNNNNNNBS in about 10 years.

I agree on the tint! I actually like the wheels though. Could definitely benefit from cutting that exhaust tip back a foot or so

I need to just sell both my trucks already and get a new HD, man they look good!
