I keep seeing people post how good the replacement springs from Jc W are and I am surprised. I was building a cj7 with a friend last year and that is the springs he bought and we ramped them here on my tree ramp and I wrapped both rears perminently with one throttle womp. Those were the HD rears with more leaves than normal so he got more thinking manf. defect and did the same thing. I dont know where he got the last pair but we installed an anti-wrap bar at the same time and no problems. I know Wranglers wrap easy but I thought that was pretty weak. We couldnt even get a breakin run on the newest springs before the wrap bar went on.
