I have a 2010 Rubicon, I have changed the front axle for some RCV, now I want to change the rear ones. I initially placed an order for the Superior, but they have been in back order for at least 2 months and they said it will take another couple of weeks. After exploring other possibilities, these are the options so far (the prices are approximate), I would like your opinion: G2, in stock, around $350 AlloyUSA, backorder, should be available soon, around $390 Superior, backorder, around $745 RCV, in stock or small wait, around $ 1600 (if I have to spend this money I may consider D60 at approx $ 3800)
