The rear shocks are equally as impressive with the same 6061 machined aluminum construction with spherical bearings and misalignment spacers top and bottom. The piggyback external reservoir features the Icon CDCV, which allows 10 adjustments to be made to compression force. Front and rear shocks are nitrogen filled, and the pressure in the rear shocks will add approxamately 0.5" of lift to the back of the truck. These shocks are fully rebuildable and will last a very long time.


The Icon Delta Joint is the star of the show up front. This component has been developed by Icon to deliver the best of both worlds for truck suspension. Increased travel and long life. This ball joint is not just your average ball joint. 

One of the key elements to the Icon Stage V suspension system is the tubular upper control arms for the front suspension. Made out of CNC bent 1026 DOM tubing, these arms are designed to achieve better suspension performance for off-road driving, with the inclusion of additional caster built into the arm geometry. The bushings are made from polyurethane and have grease fittings for servicing. The arms will also allow greater wheel travel, thanks to the Icon developed Delta Joint.


Here you can see the difference in angularity between the factory upper ball joint and the Icon Delta Joint.

The Delta Joint is really unique thanks to the quality engineered into the design. Most off-road suspension control arms use uniball joints to give extra suspension travel. The main drawback to using uniball joints is that they wear out fast due to complete exposure to the elements. The Delta Joint one ups uniball joints by delivering increased angularity while also limiting exposure to the elements with an enclosed body and the use of specialized coatings. The body of the ball joint features zinc plating for corrosion resistance while the pin features a carburized coating. Carburized coatings have incredible surface hardness and corrosion resistance. Icon also includes grease fittings that can be installed in to the Delta Joint for servicing.


Icon does a really great job of delivering a complete kit with thoughtful engineering at every step. These two components help to make installation a breeze. The front shock reservoir bracket installs on top of the shock bucket and provides a solid mounting location for the front shock reservoir, while the sway bar relocation bracket makes sure the sway bar works properly. 

Did we mention that this kit is very well engineered? Well, if you haven't caught on yet, it most certainly is well engineered. Icon includes a very nice plate for mounting of the front external reservoir as well as billet machined sway bare relocation brackets. Usually we are lowering vehicle ride heights here at MotoIQ, and to correct sway bar geometry, we usually have to use shorter end links. Since we are raising the front of this truck, the sway bar has to be lowered down at the mounting points to correct the geometry and make sure the sway bar can do its job just as well as it did when it left the factory. The Icon suspension is very impressive from a quality perspective. Everything has coatings to match the intended use.

Oh wow! When I initially looked into the new 2.8 liter Duramax engine it only seemed to be offered in the Chevy Colorado and not its GMC sibling. I've been trying to sell my dad on one to replace his decrepit Honda Pilot, but he's an old man now and my mom's Audi A6 has spoiled him with luxurious creature comforts. He wasn't really interested in the Chevy with it's less-than-amazing interior.

When did the 2.8 diesel become available in the GMC? Was this a new development fore the 2018 model year?

Those Icon parts are damn impressive. Very nice to see that they included provisions for some proper grease zerks in those snazzy Delta Joints. In a world of non-serviceable, throw-away parts it is incredibly refreshing to see Icon go the extra mile here. A little bit of molybdenum disulfide goes a looooong way to ensuring outstanding service life.

Really cool build overall. Though, as a tire mechanic I gotta bust your balls for your choice in rolling stock. I know Method makes some legit off-road racing wheels, but what's with the lame, fake "bolts" on the lame, fake "beadlock" rim? That's the exact same crap I see on Chinese wheels from the likes of KMC and their scum-of-the-Earth ilk.

I know that type of style is ubiquitous in after-market truck wheels, but come on. This is MotoIQ! You guys are supposed to be the chief anti-rice masters of the universe! I don't care that it's a truck, that's a fake styling feature meant to make it look like it has some badass motorsport hardware that it doesn't really. Rice is rice!

Let us know how reliable the overall truck is as well.(including TSBs). My main concern is the new fangled torque converter thingee. I want the GMC but until the new technology is proven I can risk the purchase just yet.

I really liked the Canyon when I was truck shopping a year ago, though I ultimately went with a Tacoma TRD. I was shopping for V6s and I though the Canyon's was way better, as was the 10-speed auto (Toyota's 6-speed sucks something fierce). I also thought the ride in the GMC was way better. I went with the Tacoma because I preferred the interior and Toyota's supplier discount was way better than GM's. I've been pleased with my Tacoma, but the GMC is a damn fine truck. Also, Hitachi makes a lot of parts for GM right now. I'm 99% sure you transmission controller, DISI rail, airflow meter, and maybe your transfer case controller are all made at my plant.

Were there specific options or a configuration that made you pick this instead of the Colorado ZR2 that comes with the baller spool valve shocks? Seems preferable to buy the factory hot rod that will retain more value over building it yourself, if the option is there. Just curious. Interested to see the rumored USA Ranger Raptor. These trucks like the Raptor, ZR2, Ram Power Wagon seem pretty cool. Nowhere to enjoy this kind of vehicle in the midwest though so I'll live vicariously through posts here :D

Actually I'm surprised there isn't a street performance variant out there yet a la the SVT Lightning. If you need to tow a track car and want something that's not a clunky boring truck to daily drive on pavement, the only real options are SUVs like the Cayenne.

What wheels are those?
Monday, March 12, 2018 1:11 PM
@cartechs, the wheels are Made by Method Wheels. They are the Grid model in titanium finish. It is really stout wheel and definitely a looker. I could have gone without the fake beadlock, but it does look pretty sick. For some reason most aftermarket offroad wheels have fake beadlocks.

@turtl631, the ZR2 is definitely an amazing car. I honestly just don't like the look of the ZR2 and the GMC looks like a nicer truck to me. I did give it a serious thought, but then what would there be to upgrade? The ZR2 is pretty much dialed out of the gate and where is the fun in that?

Hopefully, we will have another installment on this project soon.
