AND improve the ride quality or is it always a negative effect ??

Adding more height without replacing any other suspension components will always degrade ride quality. Most people don't realize it because their truck never leaves pavement.

Ranked from highest to lowest ride quality

New coilover assemblies w/ adjustable ride height and new upper control arms. You can spend anywhere from 2k to 5k on these depending how crazy you want to get.

New coilover assemblies with adjustable ride height only. Fox and Eibach makes these for a Ranger. Probably other brands as well, I didn't research much

Bilstein 5100 adjustable struts where you re-use your factory spring.

Lift spacer/puck

Thanks for the reply. That's pretty much what I expected !!

I just ordered the Eibach Pro Truck 2R coilover kit! I may do UCAs later, but I'm only planning on about 2" lift in front. Not many options for those on the market for 24-25 Rangers.
