I still have my 2nd gen shafts on the car, still working on the gen 3's. The cnc part is not that much heavier than the stock knuckles. But in stock are the newer beefier knuckles in plastic. I have not broken one of the knuckles I just wanted the bling, we also have the 22306 cnc c-hub but I was told not to run both together it's an either or thing, "BUT I MIGHT", We also have complete diff kits 22299. More options I just found are
22317 0.5 ff cnc arm hinge-holder
22318 0.25 ff cnc arm hinge-holder
22319 0.5 rf cnc arm hinge-holder
22310 2.7 cnc rear toe hinge holder
22311 2.85 cnc rear toe hinge-holder
