So after some digging I found the build thread section. 

 

What we have here is my 2014 Crew Cab Z71 4WD short bed queen. Bought a few years back as my daily work truck to put my weekend warrior back in the garage. When I first snagged her she was lifted on 34s and by the first drive home I knew the tranny was blown. Worked out a deal with the dealer I bought it from and had a 100k warranty remain installed where they paid for half of T&M. Factory crap struts with spacers front to rear came on her for a "lift". Within a few months I installed ICON Stage 1 kit to give her that quality ride effect. Love me some ICON, ride was supple on and off the road with this kit. When I decided to let go of the weekend warrior to fund the wife's new ride and changed industry's I got the itch to go back to my roots and slam her. I know I wanted to follow the same concept I did with my last mini must haves.

 

Suspension must haves:

  • Adjustable Coil Overs up front
  • Adjustable emulsions in the rear (I went back and forth for months if this was needed on a full-size before realizing it was a MUST HAVE)
  • Control arms up front due to 4wd and limited spindle offerings 
  • Flip in the rear
  • 22x10 that sat flush if not almost flush and this go around the wheel set had to be SQUARE

 

After quite a bit of research I came up with the following mods, mind you not all at once

 

Mod weekend 1:

IHC 4/6 drop kit Front and Rear, dialed (according to my comparison from ground-to-fender measure on a 19' Z71) she sits right at 4/6 and within spec on alignment.

  • IHC 4" drop arms (Front)
  • Belltech 2-Way Adjustable Coilovers (Front)
  • IHC Axle Flip kit (Rear)
  • IHC 1" lowering shackle (Rear)
  • IHC drop shocks (Rear)

Wheels and Tires 22x10 square ET +0

  • Cosmis racing XT-206R (finish chips easily but they also clean up easily)
  • Lionhart 285/40/22 (Surprisingly nice ply and quieter than anticipated)

 

After the initial mod weekend truck sat with a Carolina Squat 🤮, the rear shocks had no ass in them and my measured adjustment on the coil overs were perfect however I did install per IHC instructions with the 1/2" spacers raising the front 1". Trucks rear was as soft as a yellow belly teenager, I would bottom out axle to frame and pumpkin to bed every where I went. This was not my experience on my first go around on a full-size (96' extended cab bow-tie w/ 2/4). I was able to load that rear end up with dirt bikes and motors all day long without issue, guess there was a leaf design change over a span of 18 years 🤣. After a week of banging down the freeway I pulled the trigger on IHC helper bag kit and QA-1 shocks within spec of the drop shocks from IHC (eye-to-eye extended and fully compressed). I made the mistake of purchasing Belltech adjustable drop shocks, these only work for 4" rear drops to my dismay 😔. I also noticed that the drop shackle in the OEM hanger configuration was rubbing at ride height, so purchased the shackle flip kit from IHC as well.

 

Mod weekend 2:

  • IHC Shackle Flip Kit (allows for cleaner travel of suspension, simply shoving lowering shackle onto system was rubbing frame)
  • IHC 1" drop shackles
  • IHC Firestone helper bag kit (Rear)
  • QA1 2-way adjustable emulsion shocks (Rear)
    • Designed and Machined custom bushings to accept the OEM bolts (Inventor and Xometry FTW)

 

Once I installed QA1's, shackle flip, helper bags, and removed and readjusted coil overs I got her squatted on all 4 corners EQUALLY. I rub in front occasionally on full lock to drivers only and over excessive dips in road mostly in front. I have bumped coil over adjustment up 2 clicks from factory on drivers and 1 on passenger. I have compression up 2 clicks from middle and run helper bags with 8-10lbs in them when bed is not loaded up. Rarely do I ever bottom out these days, usually if I have the truck loaded up with people to hit work lunch.

 

Sound System:

I upgraded the sound system at some point in time between ICON's and slamming. This has been an ongoing mod debacle on my end. Started by building a steel rack behind passenger seat to mount three Memphis amps. I was using 3 Memphis amps I had from my old truck build, however the front amp decided to start sending unwarranted signals to the speakers and the rear amp after about 3 years of sitting and 6 months of using decided to finally die after an overall 10 year party in 3 different rides😒. None the less the two AB amps were replaced with new Memphis hardware while the class D (knock on wood) keeps trucking along. Doors received focal 3-Ways up front and 2-ways in the rear. Class D memphis runs a sundown 10 under the passenger ina  semi-custom box, added some height to the magnet area to accept the depth of the sundown 10 that runs on 1ohm. Memphis feeds it something like 800 watts rms @ 1ohm. Oldy but faithful Pioneer double din is running the show after trying 2 other setups to use the stock head unit. I initially tried pioneers CAN module but making fine tune adjustments or simply turning off the sub for when the kiddo is in the truck was a painful operation. Switched to an AXXES CAN setup, access to this was great, all the adjustments were perfectly accessible, however my trucks CAN did not like this system, I was getting all sorts of weird can signals and issues throughout the truck that I finally ripped that out and sent it back after trying two different AXXES units.

 

Exterior:

2nd year into ownership finally replaced the factory grill with the OEM paint matched honeycomb and updated the fogs and headlights with RIGIDs and paint matched 14-15 style headlights. Also threw in TRLS HID bulbs while I was at it and TRLS rear assembly's as well. I am an avid mountain biker so finding an easier way to load up the bikes was a must, when the pand hit I pulled the trigger on the RIDE88 truck bed system as they were doing a 25% off on preorders. Best investment for a biker ever, so easy to load and lock the bikes up, only painful when I have to fully utilize the bed.

 

Performance:

Stock 5.3, that is mostly clapped out, so I have not gone ham under the hood. Initial purchase was an air raid intake using the stock box as most factory units pull outside air vs "cold air" tech. So installed the AirRaid intake tube that ditches the sound deadening box and did a drop in oil filter. After much debate, about a years worth, I pulled the trigger on the MBRP side exit exhaust. I knew from the day I started the truck with it on that I absolutely HATED it but for some silly reason I left it on. Now I am in search of an OEM exhaust so I can throw this junk away and do an electric dump out later on down the road.  Eventually I will be swapping the 5.3 out for a LS1 or LS3 depending on what comes available next fall (waiting for prices to drop) and I will replace or rebuild the trans and will 100% replace the transfercase (culprit to my Chevy shakes when auto mode engaged) but first I need to finish my latest weekend warrior so I have a new daily while this ol'gurl is down.

 

More to come

Time for an “OEM” upgrade. These, brand new calipers, SS lines, and ceramic pads should make her feel solid underneath. Seein some sway bars in the future.

This project turned into crap salad as soon as I walked back into the garage yesterday.
 

Let’s see

 

-New caliper brackets in kit weren’t quite oem fit so they were binding with the pads

- tried to reuse old brackets, reamed new caliper mounting holes, find out after installing passenger that driver caliper bolt is seized

-buy more parts, of course I have to double check behind the clerks at Oreillys, almost gave me half the WHOLE order 

-Amazon shipment with SS lines didn show till 6pm.
-bleed system after reassembling for the 3rd time

 

What an absolute pewp show. What should have been a 3hr project started with a 2nd day at 3pm and did not end till 11pm. On a positive note though truck feels improved. Glides down the road much smoother, no more warped rotor vibration on and off the brake pedal, braking modulation has all the feelz.

 

So the what’s and what nots

 

Do not purchase:

AutoShack BRKPKG005294 Front Drilled and Slotted Front Brake rebuild kit. Better off piece mealing your own kit together

 

Do purchase:

Stoptech 950.66002 SS brake lines (FRONT)

Did a service today. Oil change, cleaned and oiled the air raid, cabin filter, detailed the wheels, gave the calipers a once over, and threw on some new headlight assemblies. I think I'm into them.😐

Finally pulled the trigger on HU I have been eyeing for 2 years now. Pioneer DMH-WC6600NEX with iDatalink Maestro RR2 interface, HRR GM3 T-Harness, and iDatalink pioneer specific harness. Only have 1 issue, rear view camera will not display. System will kick over via reverse input and manual function of HU but no display. Will need to call and trouble shoot with Maestro rep. Beyond that love the unit. Size and fitment worked well with the Scosche Double Din. Only took minor trimming to project unit out far enough to clear and dremel some of the bezel molding in areas that are not visible to end user. 

 

Also contemplating scooping up a stock 15 Tahoe rear sway bar kit from strut masters and installing. Going to pull some measures off my father in-laws hoe to see if it'll fit. If so I have some stock 1" square 3/16 wall rusting up in the garage to weld for mount points on axle. For under 100 bucks it'll be nice to control some of the body roll a little more.

Been chasing chevy shakes for the past 12 months. Think I have finally made progress on the problem and trending in the right direction. 

 

  • Replaced the MP3023 with a lower mileage one month or so ago, got her in on first lift attempt, was pretty ecstatic about that. Made a difference but did not fully solve.
  • Performed a trans service and dif fluid service while I was under the truck
  • Replaced trans mount
  • Popped in new plugs and oil service, plugs burning nicely
  • Replaced U-Joints on both shafts
    • Huge hassle on a simple job. DO NOT BUY MOOG. They do not fit. I DO NOT SUGGEST GETTING OEM. Went to dealer after MOOG did not fit via VIN search and still ended up with wrong parts. Finally hit it with SKF brand from Napa
    • These made a massive improvement to the shake issue
  • Noticed upper BJ's that came with IHC kit had 1/2" of play in them. Went with Cognito Brand 2500/3500HD Uppers direct from Cognito. 
    • Of course, as has been everything with this truck, the relief cut in the IHC arms is too tight for the BJ cup on the Cognito brand. So after some "machining" and ingenious tool use I was able to get the old BJ's out and new in. Note I sprayed the machine ends with couple coats of black prime to mitigate rust concerns.
  • Now to get the truck aligned, again, and have an appointment to get drive shafts balanced just to be sure.

 

Driving is night and day different now. Very slight vibration randomly at cruising speed. Steering input is 1000% better than it has ever felt, even from first day of IHC install. Plan to call IHC and chat with them about going V2.0 with their uppers to incorporate the Cognito BJs as the standard option. 

 

Back to loving the truck again. 😍

Well after much deliberation decided to go back up 🤦‍♂️. Replaced the entire front suspension (control arms, inner and outer tie rods, timken wheel bearings), threw on rough country 3.5” struts and lift shocks, reflipped the rear with new oem parts, wrapped the cosmos in 285/55R22’s, threw in oem tpms (dealer gave me wrong part number so going to have to go fight to get those replaced for free. Have a decent amount of equity in her so now she’s going up for sale. Love the truck but I’m ready to move into newer Sierra with LZO 🤤.

    • not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...
    • First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.  
    • I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou
    • Is it an optical illusion in the pic or is the truck really squatting that much horribly?
    • My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
