I have a 2019 Silverado HC with Z71 option. The vehicle rides better than my former 2016 Silverado LTZ Z71. Does it ride better that a GMC Denali....No or a Ram high end Truck....No but the Silverado

This could be the single stupidest thread on this forum.  The suspension will loosen up after a few thousand miles and these are trucks.  They ride rougher than cars.  20" or 22" wheels are worse that 17" or 18".  Run the correct tire pressure depending on you load.

The End.

Agree, nothing wrong with the suspension on the '19s. Stiff and bouncy with 22"s when new. Road force balanced the wheels after 1K, a few heavy loads, tow of the boat up and down the hill, and 2K miles later the rear leafs loosened up nicely.

 

Now, runs as nice or better than my '16Z71 with 17" wheels.

Cars and SUVs are designed to haul people and luggage; pickup trucks are designed to haul people,  rocks, lumber and manure. So it is impractical if not stupid to expect anywhere near car ride comfort out of a truck.

 

A case of genes - Avalanches with rear coil springs were the closest a same cost class pickup will ever get to a car/SUV ride. The most successful way to get a better ride out of a leaf spring Silverado is to trade it in for a rear spring Suburban - anything short of that will be less successful - you can't turn a white horse into a zebra no matter how many black stripes you paint on it, nor paint a zebra like a horse to get it to run a racetrack.

My LT Crew has been good since I bought it, and since getting a little over 4k miles, she has gotten better too. 

From what I've been reading, the LT models do ride the best. 

I think it's because they are made a little different from the RST models - a different spring or something, I cant hardly remember. 

It makes sense as mine rides very,very, well. 

Mine is a Z71 as well.

LTs and RSTs have the same suspension, it is the Z71 variants that differ from both base models, primarily in the rear suspension/Rancho shocks. After my '16 LT Z71 I purposely stayed away from another, those knobby Goodyear tires were great off road in heavy snow or mud, but handled like crap in turns on wet pavement, the front slid and rear end would break out on hairpins even in AWD or 4WD. Stock suspension on '19 RST with high performance conventional sipe tires handles better in turns more so with low profile sidewall 22s over the Z71s high profile knobby 17s. Handling difference is not only in gripping like a cat, but in reduced body lean and nose diving admittedly at the expense of a harsher ride. Road force balance and a few thousand miles to loosen up the suspension has made it no worse than the ride on the former Z71's knobby tires. Wait until the miles and age build up on the Z71 tires and it is slide-o-rama on pavement turns, worse, they get noisy, and the large blocks in the "treads" begin to feather toward the rear edges (frequent, very frequent,  cross tire rotation, not front to back, is necessary to compensate for this type of wear pattern).

 

Can't say how much of the latter might be attributable to the '19 body style over my '16 , but the comparison tire/wheel performance and grip of 22" Alenzas in emergency maneuvers and hairpin turns over the knobby Goodyears is nothing short of incredible..surprisingly so.....truck is as close as possible to handing if not in comfort as a sedan/SUV.

I rotate the tires every oil change or 6000 miles.  They stay in good shape that way and do not wear unevenly.

Between loaners and my own, I’ve spent at least a few days driving each of the 3 suspension packages on these 2019s on the same routes. All three have exhibited much more wayward / tailhappy behavior over broken roads than my 2016 with the base suspension ever did. This is not the only factor in ride quality, but it seems to be the main complaint when it comes to these trucks vs the last generation. All in all, I’m happy with the ride of my NHT, but it does kick out and bounce around occasionally on rough crossings, even after 8500 miles. This can be disconcerting for people who are only getting into their first truck, and I believe it is likely the main reason they retuned the suspension for 2020.

I'm coming from a 2018 ZR2 and the ride in the Silverado is very bouncy and rough compared to the smooth as silk ZR2. I have never felt a vehicle ride this bouncy that didn't have bad struts. Do any of you have the same experience?

No and sorry this is happening to you.  I have a 2019 Trail Boss, Custom Trim, Z71 with the Goodyear DuraTrac tires.  The ride is very quiet and smooth like a car.  The rear end does hop a little if you hit a bump while going thru a turn at speeds above 40mph, but I thought that was common for most trucks with leaf springs?

.02 People are driving these more like cars than trucks with a few passengers and very little weight in the bed so the rear springs never get a workout. Seems the springs may need a little flexing under load to free up the sliding movement of the ends of the leafs, and a little oil spray didn't hurt, especially after sitting with that crap they spray on. When new mine  rode like there was only a single leaf. Couldn't have been just road force balance that helped with the ride of the 22s, 2K+ miles a load of firewood and towing the boat sure flexed the springs especially when going up hills. Suspension is just right now, any looser and it would see-saw towing over humped RR crossings. Workout mellowed the ride right out, even rides better now when unloaded with just the front passengers.

 

Want a real gut busting ride? Take out the Ford flatbed loaner from Home Depot.

If they retuned the suspension for 2020, funny they didn't bother to mention it.

Well, that’s not even a GM-operated website, but I’m guessing one wouldn’t necessarily advertise this because doing so would basically admit that the 19s could have been better?

 

Nevertheless:

“The GM engineers on hand told us the entire lineup of half-tons had their suspensions (both front coils and leaf rear springs) retuned for the 2020 model year, mostly due to customer feedback.“

Boils down to a matter whether to believe either one of them or my lying eyes. To early to check replacement numbers, so next time at the dealer, it's flat on my back pulling numbers off the springs of a '20 RST for comparison against mine. Other models too.

      I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.

      Declaring victory would upset the demons that possess this Blazer, so I won't. But I did make progress today--after it put up a fight. Always a fight.   I had the day off so I spent the morning cleaning up the shop and I thought I'd get ahead of things by filling the cooling system in prep for the final part I needed to arrive: the driver's side knock sensor. Glug, glug, glug....and then the unmistakable sound of liquid hitting the shop floor. It induces the same chagrin when the sonar and targeting laser temporarily malfunction during a late night bladder evacuation over the toilet with the bathroom light off. D'OH!!! That made a mess...   Oh, hey, that knock sensor I removed? It threads into a wet port. Who knew?! Learn something new every day. Put a pin in that chore, I'll fill it the rest of the way later.   The knock sensor arrived at about 1pm. I threaded it in, connected the wire, filled up the coolant, checked for leaks, and... drumroll.... fingers crossed for a perfect start, excellent timing, model fuel trims, and ...no squeaks... Here goes.....   No, it didn't start. At all. I cranked it a few times and it wasn't sounding good. Furthermore, I heard leaking again. Jesus H Tapdancing Christ, stop leaking all over the dang floor. This time I had accidentally overfilled the coolant reservoir and the churn of the water pump via cranking caused a bit to burp out. Ok, just, breathe... Put the flamethrower down. Dang thing wouldn't burn anyway, leaks too much...   Did you know the rotation of a round crank sensor in a round hole, matters? I do now. Took me about half hour to retrace steps and realize what I had done. Then it started right up.   No squeaks. The squeak was the old balancer.   Once it entered closed loop, fuel trims are dead on, hovering right around zero at idle. No more -30%. I'll credit the injector rebuild on that one.   Timing? I think there's an OBD 1.5 translation error with my Actron scanner. It's anywhere from -20 to -30 at idle, sometimes as high as -40 cruising. Sorry, the engine just isn't running that smoothly at -40 degrees ignition advance. It's just not. It's smooth all through the rev range and has decent power. I'm going to have to trust the seat of my pants on this one.   The new exhaust is very quiet. The old catalytic converter? Not melted, but definitely not healthy. Rains glitter when you turn it on its end...all the precious metal is flaking out. Once the new exhaust system burned in/smoked off a bit, the engine's exhaust smell is normal again. Not that I'd recommend going around huffing car exhaust, but, you know what I mean?   One problem to correct. The new exhaust has the opposite problem of the old spliced up exhaust. It wants to hit the floor where the old one wanted to rest on the cross member. Happy medium, please? Still noodling on that one, need to look at how I can adjust some hangers.   I don't know what's next. On one hand I want to run away from this thing as far and as fast as I can -- there have been a lot of NOT fun moments. On the other, now that it kinda drives nice, maybe drive it around for a little bit?   Shhh... it's not currently dripping oil all over the floor. I can see just a little wet at the bottom of the timing cover where it meets the oil pan seal. It's not dripping multiple drops with every ignition cycle, in fact, after some driving this evening it has yet to even form a drop that could drip off yet. But the weekend is young... I fully expect this could turn into Exxon Valdez by Sunday. Because this Blazer hates me. LOL.

      About that:   Once upon a time in a land far far away lived a car company that was shy about taking your money and wanted to be sure that they gave you more that you asked for so that you'd come back. No really, not a fairytale. 😱   But after the field got thinned out enough to limit the competition it seemed good enough to give you only what you asked for. Fair enough I say but in such a market you have to give something the others are not or they go to the one who does. Gimmicks or glitz. Oh, fins and chrome. Yea, shinny crow like cars. Yum.    Field narrows a bit more and 'brand loyalty' becomes a thing and the minute it does they start thinking to themselves, "Could we make more money if we gave them less than they expect and they will hang in there for brand and comfort with the known?" They gave it a try and da*n, it worked!!    Well, what if we teach them, groom them into believing that less is "Normal" and cut some more corners. Will that work? Oh heck yea!    🤔 I wonder, can we give then WAY less than they expect and make them mad enough to spit nails and STILL get them to pay up? Sure, if we get everyone else to do the same so that the choice is less or nothing at all. How would be do that? Platform sharing.  What a concept, right?  Steal like there is no tomorrow and it's legal too!    Truth is no one is going to give up driving, not for very long. The Gen Z crowd is fine with it and will be as long as someone not Gen Z will haul them around. At some point we all die.    Economic voting only works if you cast a NO vote now and again and enough of them to get dumb and dumber to wise up. Well, that's how I was taught anyway. And it should have worked. Would have worked. But the Bail out!!   Look, you have another choice if  you take that bag off your head. If the dumb it down to some predetermined expectation of how John Q Public will use it the, that is under design it to failure they you use it to a lower stress mode. D'ho!    A 1950 Royal Enfield Bullet 500 will go anywhere a Suzuki Hayabusa will and for just as long. But you will have to treat it for what it is and not for what you wish it was.

      Bridgestone vs Goodyear tires?

      By Vu1can · Posted

      Maybe I was just too unlucky, but I had nothing but bad luck with Bridgestones. Out of 3 sets, they all started losing a lot of air when they got down to about 1/2 tread life, and at that point also wet traction suffered more than it should have. Also, the only tire I ever had in my 60 years of driving that had a side wall blow out was a Bridgestone.   I'm currently running Goodyear Wrangler Workhorse AT and am very happy with them.

      maybe when the trip is over, check all the other joints in the front end, like all the ball joints, tie rods, pitman & idler arms, etc...
