CVJ axles, Inc. out of Denver. I've posted many times about this. I don't think I've ever seen anyone lift a runner without the OEM boots failing. In my opinion, long travel boots are the way to go to ensure you've got plenty of room for flex. IIRC pricing long travel inner and outers was slightly less expensive than just ordering rebuilt custom ones from CVJ . It's easier to swap the axles than re-booting. I think the axles were $89 ea + $40 extra for the long travel outers. Check it out if you'd like. I dealt with a fella named Steve. He was very helpful -
thanks for the reference
what is their lead time? and are their custom axles OEM or aftermarket?
