Im giving these a try on my car. If you know anyone doing a lift kit on the new 2018 and up jeep JL wrangler, they have these grey rubbery plastic isolater's on the factory springs. Its kinda the same thing as cutting the hose, but its already split and made the right size. Theyre working so far on my car. Not sure how long theyll last, but i didnt spend any money on them and thought id give em a try.
