Mystery suspension issue

[southern_sierra]

6.2 get a beefier sway bar maybe?

 

Heavier axle assembly?

 

Stiffer springs?

 

Just throwing it out there

Does the 14 and 17 have the same size wheels? 18 inch tires will ride better than 20 inch because of more sidewall flex.

Same

 

'17 5.3 slt all-terrain crew cab - has trailer brake controller

'14 6.2 slt all-terrain double cab - no trailer brake controller

Same 20" wheels with goodyear sr-a's at 33-34 psi

 

'14 leans slightly less turns and can't absorb a pothole for the life of it

'17 leans slightly more in turns, absorbs potholes much better.

My 14 would bottom out in the front end with the stock ranchos. I replaced all four ranchos with stock black shocks which are standard on a regular 4x4. They rode better but still would bottom out. I replaces the front only with Bilstein 5100s on the 3rd height setting. The ride is firm but good and no more bottoming out. And no more out of control bouncing at highway speeds. The ride is still not like I want it but think It would be better with 18 inch tires. The Bilsteins seem to settle in after a few months and are not as firm as when installed. I keep my michelin m/s2 air @ 32 cold psi per the door sticker.

We're the control arms the same?

I've heard that the aluminum control arms may rebound faster because they are lighter. Don't know if there's any truth to that, but that may have been a difference between the two trucks.

 

I will say I had a loaner with with aluminum control arms, Z71/rancho and it was night and day difference, better, softer than my nht max tow with steel control arms and no rancho shocks, however that's a lot more differences.

Pics are of the factory Ranchos on my 2014 SLT at approx 50,000 miles. I think they were actually bad at around 25,000 miles, not impressed by the Ranchos!. Put on some Gabriel Ultras on the back (20 bucks each delivered) rode much better never messed with front ones and traded the truck.

 

New truck has the MRC we will see how that holds up. I have heard that a replacement Magnetic Ride Control shock is like 600 bucks each LOL

I hear ya, but my problem is I just drove a truck with the ranchos and it wasn't all that bad at taking a bump. It felt like a normal truck should feel. My '14 feels like a sledgehammer hit the truck every time I hot a pothole.

Check and confirm the "suspension" package on the build sheet or sticker are the same. I also remember seeing on here the '16+ trucks have a different part # rear leaf spring so it could be they changed the front coils also? Not unrealistic to see some changes on a completely new platform.... If the build suspension codes are identical, tires are the same etc then either your ranchos are wore out or GM changed something. Simple as that. Think of how many iOS updates your iphone has had since 2014...... ! And as other above mentioned I've seen our trucks with aluminum control arms and stamped steel. Mine are aluminum, my Superintendent has the same truck as me, both are 14's but his is a Z71 and he has steel control arms. Aluminum is the way to go my friend.

I was curious to see if the MRC shocks were actually 600 each as someone had told me but it looks like they are around 340 on the GM parts direct site at the present time and as the technology becomes more commonplace that price will probably come down more in the next few years.
