As in, the ones that are made for the JK vs these new ones made for the JL? If so, it's hard to beat something that's made just as tough only, can now be bolted on versus welded on. They are more expensive but you do save on being able to install them yourself.Those sliders are bad ass. Certainly what I’ll be doing whenever I can finally get around to building up the JL. Curious what you think of the bolt on vs the weld on.
