I love my RCV's but with that said, if money is an option, good CrMo axles shafts with full circle clips are the way to go. If not, go RCV's. Prosteer's all the way. They are rebuildable, that should be worth the difference. ARB locker. I have not experience with any other locker besides the E-locker but to keep it simple for me, if its good enough for Mel Wade, it's good enough for me!!![]()
