Just took my '14 double cab 6.2 in for service and have a '17 crew cab 5.3 loaner.

 

'17 has 2k miles

'14 has 30k miles

 

Both are slt all terrains

 

Just figured I'd point out the difference as I litterally got out of one and into the other.

 

Motor - Love the 6.2, 5.3 is ample but definitely feels pokey by comparison. The although both are very quiet, the exhaust tone is much deeper and more "badass v8 grumble" on the 6.2.

 

Trans - Not much difference between the 8 and the 6 speed. 8 speed feels a little better and less confused.

 

Noise - 6.2 interior has noise cancelling, 6.2 has noticeably less noise from road and engine

 

Ride - This is a mystery, but the '17 handles bumps wayyy better. The ride is a lot less punishing going over a pothole or something. Both are all-terrains and both have the ranchos, similar tire pressure. Baffled by this. '17 have fresh sr-a's vs my '14 which are about the end of their lifespan.

 

Handling- '14 handles better from a performance aspect, something in the suspension is softer in the '17 I believe. Whatever it is I prefer the '17 suspension any day. It's just a better ride.

 

Headlights- haven't driven at night yet, but man the '17's front end looks sexy in real life.

 

Mpg- seems almost identical

 

-iphone connect, not as good as you would think. Don't prefer the '17 radio much more than the '14.

Great info, I'm sure lots of people cross shop the 5.3 and 6.2 if they are looking at a new GM truck to see if its worth the price premium I know I did and totally agree with your points although I didn't notice the 6.2 being noticeably quieter compared to the 5.3 back when I test drove one but I'm definitely with you on the slightly deeper exhaust note the 6.2 gives off, its much nicer!

 

As for the ride I'm not aware of any suspension re-tuning that occurred between 14 and 17 M/Y but I also noticed a huge ride improvement between my 2015 Double Cab SLT and My 16 Crew cab and I think that comes down to the Crew cab over the double cab, with the Big 6.2 hanging out front on your truck and only the double cab leaved the weight distribution VERY heavily favoring the front then 6.5ft of box leaves the back end less planted and seems to jolt and jitter more over bumps however the double cab sheds quite a bit of weight so that probably helps with handling. Meanwhile the Crew cab has several hundred more lbs placed father back in the chassis and a short bed so although of course its still front weight biased the extra weight placed further back really helps the unloaded ride characteristics.

 

It also makes me think this is the case because the ride quality once I had my Enclosed trailer hooked up (~500lbs tongue weight) both my double cab and crew cab ride felt about the same but unloaded crew cab is clearly smoother.

That was my first thought, the crew cab. But I role around with about 400-500lbs of tools and supply's in the bed of my double cab almost all the time. With that weight in my bed, the '17 crew cab is way more compliant ride.

 

I didn't think there were any changes in suspension either. I drive on rough philly roads every day. This '17 is for some reason able to absorb potholes and various other bumps much better.

 

My '14 feels like a pickup truck, this '17 crew feels more like I'd expect a tahoe or suburban. Same exact wheels and tires too.

 

The only difference I see in the suspension is my double cab has steel control arms and this '17 has aluminum. (I think)

As for the quietness of the 6.2 with the noise cancelation. When I say noticable I mean I only notice it because I drive a 6.2 everyday. If you were just test driving them unlikely you'd hear any difference. It's barely noticeable. It's only certain noises that I can pick up clearer in the truck without the noise cancelation.

 

I will say I was getting on the 5.3 a bit more today, man does the exhaust note sound horrible stock! Sounds like a wimpy v6 or something. The 6.2 sounds like a cammed big block by comparison.

I actually think my 5.3 sounds great when I get on it. I will turn down the radio sometimes to hear it in all its glory. I am sure the 6.2 sounds better but I disagree with your exhaust assessment. My 14 Silverado cab is very quiet and coming from my 06 sierra it is a HUGE difference. That is one of my favorite things, is the cab noise is so low.

Ok I have the upgraded factory '14 headlights, which were horrible before the upgrade, and not bad after.

 

'17 headlights blow them away, i think everybody knew that, just further confirmation

ride is better on the loaner b/c your shocks are junk. Mine were shot around 5,000 miles..............zero exaggeration.

I've heard that, but wouldn't that just make it sloppy? Not firmer?

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      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
