Ya, you'd save on some weight, but IMO it's not worth the hassle of changing them out. The added weight really isn't going to hurt you. If it was a CJ, which have a tendancy to wheelie, then i'd say go for it, but your runner isn't going to know the differance. Marlin carries enough spare parts in the bed of his rig to build 5 trucks and does every trail in the country.
