Giddy Up Build/Refresh for my 2011 GMC Yukon Denali

[Denaliz]

Just putting a starting point for my upcoming build.

I bought my 2011 GMC Yukon Denali new in late 2010. I started upgrading things in 2015 and it’s been thru several high end audio setups. Removed/converted the e brake to an actuator to make room for Custom built kick panels, console that houses a 10” Raven xl subwoofer firing up into the dash (no rattles) amp rack, speaker pods and bunch of custom wiring.I still compete in sound quality car audio and enjoy the hobby.

Performance wise I’ve added the well known magnaflow 12909 muffler only since we have 3.5” pipes oem. Airaid JR CAI, K&N filter, catch can, Blackbear performance tune, and Eibach Sway bars.

I’ve always replaced any molding/trim pieces that got worn out or needed replaced down to the clips. So she’s in pretty good shape to begin the build.


Finally started putting together a plan for the performance upgrades I’ve wanted and spent many hours researching, asking forum questions and meeting with multiple vendors for the install and parts selection.

The build will consist of the following:

Vossen HF6-1 24” wheels with a gunmetal grey finish.

Belltech 753 kit for a 2/3 drop/ keeping the z55 suspension

TSP Cam Swap Package- AFM/DOD and VVT Delete. I asked for a cam that would play nice with the supercharger that’s going to be installed at the same time.

-TSP L92 Truck Cam 216/228, .600/600,
113 LSA (25-TSP216228-113)
7.400" (25-7400-1)
TSP.660" Dual Spring Kit w/ Integrated

One-Piece Seat & Seal, Titanium Retainers, PAC Springs #199-TSPPACPOL660SPRINGKIT.

Supercharger- I had all but decided on a Maggy TVS1900 but the shop handling the install wanted to look into a whipple. Choice is mine wt the end of the day and they have no issues with whatever I want.

I did close to a full z55 suspension refresh in the last 24 months replacing the rear shocks, front struts including the entire coilover assembling and springs. Tie rods, LCA and ball joints.

For reasons unknown both of the front struts locked up so I have 2x new oem ACDelco airside struts going in on a warranty replacement.

I’m also having the Denali repainted staying with the oem Onyx Black just making her perfect as I can.

I’ll update as I get the remaining parts in and start the install.

I'm in for the refre$h! I can't wait to see the numbers it'll put down once everything is dialed in.

Are you going to baseline the truck before you start this latest round of mods? Like take her to your local drag strip or dyno?

Yes/ good call. I plan on having it dyno’d at a local shop pre work.

FYI- I am far from an expert on this stuff. Now audio and wiring I’ve got down cold in my sleep so this is a somewhat new world for me to

So a good buddy of mine does automotive interior, fab and has a high end car audio store. He’s going to help me design the new interior fab. Not sure what all we will end up doing but I’ve seen 1st hand his custom interiors and hand stitched leather work. I’m in good hands.

Below is a pic of one of the trucks he just knocked out

A lil closer- just need a missing awol wheel to make a set

Interior looks great! Good luck with the future mods.

The missing/AWOL wheel showed up today along with my center caps thankfully. Now I’m waiting on TSP.

Project finally started.

Dropped off my Denali to have the Belltech 2/3 drop kit 753 and some oem GM Z55 suspension parts replaced.
2x acdelco 580-434 struts along with new GM strut mounts (entire front coilover assemblies were done about 18 months ago) front & rear upper control arms and trailing arms using all oem GM products.

The plan is to have this done and the Vossens mounted up with the TSP cam package and SC arrive.
