Denali62's iridium 2015 Denali build

[Denali62]

 

 

Well I picked this truck up on October 28th of last year and so far I have managed to take it from a bone stock luxury truck to something that reminds me of how I thought it should come from the factory if I ever was able to get a Denali. Almost like a John moss inspired rendition of the K2 Denali. Anyway off to the specs.

 

2015 Sierra Denali short bed crew cab

L86/8l90/3.23

 

Started out by adding weather tech rain guards and floor mats.

 

I couldn't stand the dead quiet exhaust mixed with the timbre of the "active exhaust valve"....what a joke. So I hacked the muffler and flapper and welded a straight pipe in is place

 

Then added the pace Edwards full metal jackrabbit.

 

After that the puny tires gave way at 5500 miles for a set of 285/55 20 bfg ko2's

Had the front windows tinted 20% and a 5" glare strip

 

Next came the kicker substage and vled headlights and fogs

 

Followed by a suspensionmaxx 2.5/1 lift kit.

 

Then Christmastime hit and I was actually able to sway my mother and father (I'm 31 not 21 so I really didn't expect them to feed my addiction like they used too lol)into getting me an afe momentum hd intake system. My wife got me a trinity including lews tuning services. Things are going swimmingly.

Mbrp cat back went on next and things really started working together well. My trinity was showing 5.4-5.5 0-60 with an awd launch.

 

 

Next came the long tube headers/off road y. And more tuning. It is at this point (minutes after flashing my post header wot tune in). That I ran 5.15 seconds 0-60 in auto 4wd shifting at ~6300(2-3 not 1-2 I hit the damn limiter every time I try to hold first)also added Taylor wires

Switched to Mobil 1 5w20 at this point since we bumped the rev limiter up to 6500 and I play up there quite a bit.

 

 

Neighbors complained about the noise(rightfully so it was LOUD) so I installed a spin tech 9000 series and an aeroturbine 3535xl into the mbrp catback. Which I highly recommend. Deepest tone I've ever heard out of a sub 500" v8 and as smooth as Mesa boogie distortion.

170 degree thermostat installed, which led to me discovering what a few others had already- that the temp gauge in the digital cluster is no more than a cartoon for pencil pushers and desk jockeys to confide in. Dash command showed 172 while the gauge showed 210 lol I trust in obd sensor data over the gauge at all times this just proves it in an extreme sense.

 

 

At this point I let my redneck roots outweigh my racing bloodline and "got some more tar under there". 295 60 20 cooper stt pro's which I'm sure I'll love whenever I finally decide the fun off roading is worth the hard work cleaning up the next day. But at this point the truck has 15k miles so I'm sure that the coopers will be long gone before this truck is even broken in. I love them and hate them at the same time. Don't need them at any point(the ko2's drove better in every way and I never stuck them)

 

So anyway I'm butt hurt that my tires are heavy and kinda wobbly and rub but they do look like they can go through some mud and that's the cliche look around here so I did it there are you happy!!!lol

 

Ok but no amount of tire buyers remorse can stop this project.

 

 

There was way to much chrome in little blips and semi perpendicular lines all over the truck and on a dark color that just looks retarted. Sorry to you people who say you like it but you may be in denial and just to afraid that it won't look right or maybe you are just cheap and lazy idunno. No offense to anyone it's late and I have now taken my meds lol.

 

Oh yeah too many chrome blips. I took care of that by stripping the gmc and Sierra emblem on the t gate and had emblem pro's make me a black chrome version of their l86 6.2 emblem

 

Also plastidipped the Denali emblems and the chrome door side molding in anthracite.

 

Used ACdelco Rattle can iridium to do the mirror caps along with a few thin coats of perfect match clear(it turned out really matte looking but very even to the point I love it, I think it was the humidity that day)

 

Used the same paint on the doorhandles and several coats of the clear on a dry windless sunny day which ended up matching the facory paint perfectly in color and luster. Best rattle canning I've ever done if I do say so myself.

 

 

The vled's were a mild sidestep/upgrade to the poor factory Phillips hir (I tried the vosla bulbs too but they didn't make enough of an improvement to warrant keeping them so put them in my toolbox, they will probably get shattered in there lol. Latest upgrade consists of Morimoto 55w 5500k headlights and lmz 25 watt fogs. Vleds in the tag lights cargo lights and reverse lights.

 

Removed steps in anticipation of the arrival of rb10's

 

Sorry for the pics out of order I'll figure that out later

 

pending:

 

1.75" bora wheel spacers are on order and lots of trimming bashing and maybe the new 3.5 rc lift for magneride with uca's cuz I'm rubbing bad now on the liner and the sway bar and the upper control arm.

 

I have an lt1 Intake and all the tidbits needed to install(idler,belt, and 45* intake elbow, just waiting on my elite catch can to come in so I can do it all at the same time.

 

 

Would really like a cam and heads but I think it might take me too long without a lift so I may farm this out to dynospeed in Memphis using lmr, vengeance, or tsp parts. Lt4 hpfp at that time.

 

After that I'm thinking I'll get a better lsd and a circle d converter and call it a day.

 

I am sure I am leaving something out but I'll edit this post over the next few days

Rb10's will be in today. Pics to follow. I love the look without any steps but my wife is 5'5" so I figure the rb10 will stick out visually the least. Well besides amp steps but they are heavy and over engineered at the very least. Also have one of everything Zaino makes on the way along with 303 products as well.

[TXTruk15]

like that L86 emblem. Truck is looking GOOD

[TXTruk15]

you can't go wrong with that AFE Momentum - I've had it on for about 14k miles, love the sound of it also

 

[Denali62]

TX truck: quick Question....

 

Have you noticed any weird ticking type high pitched resonance coming from your momentum air box? Particularly with the plug on top removed? Took me forever to trace down an Almost exhaust leak type sound but very faint and most importantly in the complete absence of any exhaust leaks (ask how I know)

 

Thanks

[Denali62]

Got the Gorhino rb10's on this morning (by 6:30 am!). Took a few pics while spraying my yard.

[Adrian Berryhill]

Excited to be involved in this build!! Wait til you guys see what is next. ?

[Denali62]

Hey Adrian! Welcome to the forum and all that.

 

If you would go check out the post I have going on the diff drop we need to figure out.! Quite a few members are in the same boat as me with the 7.5 rc kit. Feeling vibration from the cv's under any kind of load in 4wd.

 

More details on that post. We need a quick fix and maybe you guys could fab up the prototype using my truck. I'm not looking for stock angles just enough to prevent binding.

[Denali62]

With the 8l90 it turns out with 37" Tires all that's needed is a 3.73 ratio to get me to the equivalent of a stock tire truck with 3.42.

 

That will probably be the next thing I do. Then the Rcv axles
