Because the stock over-boosted power steering gives very little to no road feel. I’d rather know what my car is doing than be able to steer with my pinky finger. It also weighs a ton, and depending on the engine, headers etc used it can be much harder to work around than the smaller manual steering box.
I prefer manual steering, especially over the stock Mopar power set up. Even with a fast ratio, 16:1 manual box the steering effort and feel is great at speed IMO. Below 10mph it can be a little tough but I also run really wide front tires and a ton of positive caster, both of which add to the steering effort at slow speeds compared to a more “traditional” set up with narrower tires and less caster.
