We've certainly seen a lot of photos of the all new 2019 Silverado and Sierra. Photos of the interior and photos of the trim packages. Photos on-road and photos off-road. But what we have not seen yet is how the 2019 Silverado and Sierra's new T1XX platform looks mechanically under the surface. Until today. 

 

GM-Trucks.com has obtained exclusive copies of parts diagrams for the next generation Silverado. From these drawings we can gleam just a little bit more about how the next generation trucks are different from their predecessors. 

 

Set One: Front Suspension, Differential, Axle, and Driveshaft

Our first batch of drawings show us a few things, mainly the new T1XX front suspension setup (which is similar to the Colorado), a new HD-like front differential, a new rear axle with new yoke, and a new driveshaft setup.

Set Two: Front and Rear Brake Calipers

Our second batch of drawings show the new 2019 T1XX front and rear calipers (with electronic parking brake).

Set Three: Engine Blow Out, Dual Exhaust, Cold Air Factory Intake

And our third batch of drawings show what the new L87/L84 looks like blown apart (with individual cylinder deactivation instead of an AFM VLOM). We also see the new dual exhaust and brand new airbox design that draws cool air from the front of the vehicle instead of the side fender.

 Thanks to our "GM deepthroat" for sending these files our way. Next week we head to Wyoming for our first drive of the 2019 Silverado while our 2019 Silverado LTZ is being shipped to our dealership from the factory.

Wow big departure for the front brakes.  Hopefully it cuts down on brake wear/rust issues that the current and former designs are susceptible to. 

 

Interesting change on the intake.  Aerodynamics?  You close the fender off, that's less air being diverted through it.   

 

The dual exhaust looks like a really nice setup.  Shame the tips are duds, but I guess that's good? 

 

Bout time the split case front end died.  HD debuted that style front diff first, Gen 2 Colorado/Canyon have it as well, both before the 1/2 ton.  Should add some welcome front end strength, as evident by VYU plow prep being available on all 1/2 ton cab configs with the 5.3.

Looks like the air filter that fit the 2000 model GMT800 and up will no longer fit the 2019.  I guess it is odd to have the same filter fit for so many years and I guess it had to end some time.

I think this is proof at least that GM is finally truly changing the Silverado and not relying so much on past platforms.

I like the rectangular dual exhaust tips/bumper area.

Different than Ram and now Ferd's  2019 dual exhaust F150 setup.

Wow, the rear differential is that bad in the 14-18 trucks that they only used it for 4 years before redesigning it again.  Hopefully this will solve all the manufacturing issues they had with the previous ones.

Just having mine done under power train warranty now... Only 300 miles to 100k... Close one.

My 2015 Silverado was so bad I went through 4 rear differentials before I had one that worked (didn't whine) in less than 2300 miles. (no that's not a typo).

I would be curious to see if the new 2019 bumper would mount up to the 14-18 K2 trucks.

I really like the dual exhaust and rectangular tip/bumper cutout on the new T1's

Only issue might be where the bumper wraps farther around the bed sides.

Are they actually scooping air from the front nose.  That looks more like some sort of ram scoop to catch air from the base of the hood.

It used to be supplied solely by AAM. Now GM is building their own version in Michigan. That's why it looks different.

First time I've heard of someone going through 4 diffs in the 12 bolt. That's almost as bad as that worthless 10.5" axle Toyota uses in 2nd gen Tundra.

The intake air is coming from the front now instead of the fender.

Probably not a Ram Air type of system due to all the jogs and bends to get to the intake itself.

It  will for sure grab more air then a pip just facing down..

My 2018 GMC Denali had Magnetic Ride Control adaptive damping suspension.  Why don't these Chevy trucks have this?

      286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔

      cam upgrade in CA

      By AidenVorpagel · Posted

      hello I recently bought a 2012 gmc 1500 with a 5.3 and have a AFM disabler on it I'm interested in doing a cam but I'm worried if I remove the AFM system I will fail smog does anyone have info if they are able to detect that or a work around to it (not talking about hot smogging) please let me know thank you

      Possible lifter tick after DOD delete

      By B14Sierra · Posted

      Update. I started chasing down my symptoms. Started first with pulling valve covers and looked at everything. Everything looked good and couldn't hear or feel anything different. Then a compression test. 240 psi or really close on each cylinder. I was worried I was a tooth off of timing. Not bad for an engine with 173,000. Granted I did put new heads on. I sprayed water around the injector area to see if I could hear a change. Nothing. I hooked up my new hp tuner which I should have done in the first place but I don't really know what I'm looking at just yet but am learning. I noticed the fuel trims were way off so that told me I have to have either a bad injector or exhaust leak. New injectors, so I did the shop vac on blower and in the tail pipe. Sprayed soapy water and found the exhaust flange on the drivers side was leaking. I didn't think it would be that considereding I pulled the heads and left the manifolds attached. I did have the transmission replaced not long ago. They must have not seated them properly but I guess I didn't notice. I put in new gaskets on both sides. Which by the way isn't a bad job but I had a hard time getting them to seal right. Took two attempts. Reset the fuel trims and the ticking is gone, engine runs smooth and acceleration has improved. Got to feel the real difference with that stage 1 cam. It's not that big of a difference but it does add a little more. It feels like how the truck should have been from the factory.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.
