Easy to install and maintenance free. I have a 2019 Tundra and am towing a 7000 lb RV with an 800 lb drawbar and can't stand the way my leaf springs rest on the lower safety bar. With a weight-distributing hitch without springs, the truck dropped 1 3/4 lengths from floor to fender. I originally bought the black ones but they only added me 3/8" so I still had 1 3/8" of sag. So I bought the yellow ones and got the best results. Satisfied. As for daily riding with the springs, it's stiffer in the rear, doesn't bother me, but they can always be removed and put back in if needed. They are unscrewed from the strut. I have black ones too and can swap two tone ones if I want.
