Suspension concern

[Relly rell]

Whats good my Hoe family. I have 2019 Premier that ive converted over to regular shocks . On the front ......new upper control arms new lower ball joint new sway bar links and bushings shocks are KYB SRX4545 which are front leveling 2inch raise . Rear new links and bushings with bilstein 4600 .its depressing that I assumed that everything would have been smooth but on the contrary the front rides rough and it sounds like thudds bouncing feeling throughout rear seems cool but cant tell because somewhere its all off .. please I need suggestions.. better choice in shocks something that I did wrong my brain is not trying to figure this out

Those Bilsteins can't hope to compete with your original suspension. They're known for delivering a more firm ride. On top of that, you went to a dumb suspension rather than the electronic suspension. The electronic suspensions were designed to accommodate 20 inch and larger wheel diameters. Go to an 18 inch wheel or revert back to the original suspension to get back what you lost.

What @swathdiver said.

The factory suspension on your Premier is specifically tuned for your vehicle and is hard to beat from an overall performance standpoint.

I know that you've completed your project and will most likely have to live with the inferior results. As stated above, IMO as well, the GM OEM suspension is the best, as my truck had been converted to passive before I purchased it, and then I reverted back to the GM OEM suspension for my truck, and the improvement was very significant.

In full transparency, though, several folks on this Forum have converted to passive systems, and they are happy with them. Hopefully, one or more of these folks will chime in with their experiences and offer advice.

I recently removed the mag shocks and went with the Fox shocks. The ride now is the same as before my mag shocks failed.
My 17 Premier has over 120,000 miles.
I don’t tow with the vehicle so I really don’t the rear air shocks, and the GM factory parts replacement price was more than double then what I paid.
