I have a 2015 suburban ltz that I have had nothing but issues with the suspension. The magnaride went bad so I replaced but with Rancho quicklifts in the front and rancho in the rear. (Wife and I expecting another child so went to save money) I disconnected the magnaride system. It does ride a little better but still bounces some. The rear is squatting which i hate. So I need some ideas what to do. Should I keep the setup I have and try to make it better? I do tow a boat some if that helps.

 

If the 2015 is similar to the 2014 and earlier models, when replacing the stock rear shock absorbers with regular shock absorbers, you have to also replace the springs. The stock springs are not stiff enough and the rear will sit low and bottom out on bumps.
