I am thinking about getting the 4" super lift and upgrading the control arms to the rockarms, I think thats what they are called, that twist. Also upgrading the shocks as well. I was thinking, If I am going to pay for the upgrade I would like to get the best for my money. who offers the best control arms. It seems that FT/RK/RE all have nice ones but would any of them work with the kit or would I be better off just sticking with the superlift upgrade. If you are wondering. I like the reviews I have read on this lift and that it is install freindly for just one guy with hand tools. I like to do most of my work myself. Any input would be great to hear. Oh, and one more thing, The Full Traction arms look quite BEEFY me likey! are they all about the same..... in beefyness...
