I just pick up a 2017 Silverado Z71 and I’m having the same problem. Took it back to the dealership and they said it might be air pressure since it was at 47. Too high can make it too bouncy. So they brought it down to 35. Still having the problem. Are you still having the problem or did you get it fixed? If so, how? Please let me know because it’s bugging the ****** out of me.

Welcome to the site.

You asked a question to a thread that is almost a year old, use the quote function and it will send a message to the last post.

You have the Z71 suspension, so it will have a tendency to do what you are describing, weight in the bed, or go with a "softer" shock and see what it does for you.

Sorry I’m new to this. I was searching around on why this is happening to my almost new truck and came across this so first thing I did was comment on it..

Anyway, so the Z71 suspensions have the tendency of doing this? Within this first week of having the truck, I’ve had three close calls on the highway already because I practically lose control of the truck. You’re telling me it’s normal?..

Can it be bad shocks like everyone else says it is?

You are doing just fine, already know how to use the quote to get a members attention.

No, not normal, describe the speeds you are experiencing the problem. I would also look under the truck to make sure your shocks are not leaking, they are Factory grade Rancho's, not bad, but not the best either.

By just going 30-40 mph and going over bumps and potholes(sewage caps), rear end of my truck would jump/jerk/sway to the side. Now just imagine going 50-65 mph on the highway going over bumps and potholes, and the truck jumping to side going that fast. It can get pretty scary. I know some people may argue the fact that the bed is too light, but I don’t think it’s normal to have it jerking/jumping to the side like that. There just has to be a better valid reason why this is happening.

Also, the sales person that sold me the car at the dealership is saying it’s because of the Z71 suspension. I told him it can’t be, because I have a 2002 Z71, it’s pretty much a pice of crap at this point but it rides perfectly fine. So I’m here telling myself no, it can not be the Z71 suspensions. It just can’t be. It can’t be normal. If this is normal and this is how GM makes them, I wish I would’ve known so I would’ve stayed away from them. So I’m really really trying to find a solution to this because right now I feel like s**t for spending $30k on a 2017 truck that rides like crap. Please, please help if you guys can.

How many miles on the truck? If out of warranty, did you buy it as a Certified Pre Owned?

And one question that is going to come up, how long did you have it on the test drive, and where did you go? Did they keep you close to the dealer, all surface streets, or did you go out on a highway/freeway?

43,****** miles on the truck. I don’t believe it’s a certified pre owned but I did purchase the protection plan that covers everything except cosmetic work. So I know those shocks are cover if it’s really bad.

Check out the Bilstein threads on here, maybe that is a way to go.

Sorry I have no idea on how to do that. Lol. Again I’m not usually on these kinds of things...

No problem, not the easiest site to navigate.

Two ways (well kind of) top of page under your log in, there is a search tab, works ok.

Other way is to go on your internet search engine of choice, example, plug in Bilstein shocks for a 2017 Silverado on Gm-trucks.com, scroll down the page till you see the site, and click on.
