Strut assembly Bilstein or GABRIEL

Your Kia Sorento doesn't need the yellow B6/B8 struts. Lol. The black B4 will give you the original ride height and oem ride quality. The yellow ones are for performance.

The B4s are better than the factory struts and shocks.

No experience with the b16s but I went from lowering springs on stock struts to lowering springs on b8s and it made a world of a difference.

Get good parts: original ride quality, not economy, and probably KYB or Gabriel (Monroe has long been a decent brand, but people tend to question their quality these days, especially here on Reddit).

I installed B6 struts on all four corners, top mounts, end links, and new bump stops. The suspension arms were in good shape and didn't actually need to be replaced. My car has been garage-kept and has 47k miles on it, which might explain why the rubber was in decent shape. My bump stops looked much like yours, and when I took out the front struts, I could compress them with my hands. I was basically riding on the front springs with no dampening. With the new struts, the ride is much better, and the car feels excellent over bumps. The B6 struts aren't super stiff (about 20% stiffer than B4), and the ride is similar to a factory with OEM springs.

Difference with the new b4s was night and day vs the 20 year old ones.

I don't care for stiff springs. And, Bilstein shocks/struts have always been perfect in my vehicles(ride/longevity/handling).

They’ll work on a 2wd but not very well. Ranchos are junk. Spend a tiny bit more and get something better. Bilstein 5100 have been good to me for years on many vehicles.

I had B6 EDC front struts installed on my f31, and the same thing happened to me - the front was substantially higher after installation than it was with the OEM front struts.

There are some cheaper models available from Monroe and Gabriel but I've used both on customer cars and been very unimpressed. They felt harsh immediately and were clunking within 10k miles.
