I think it may be worth it for some people if dynatrac made a kit for the front. Example, I already have a PR44, lets say it is now time that I need a new rear axle and I want to go full float, order a PR60 8 lug and buy the front free spin kit that converts the front to eight lug. And then you won't have to do a 5x5.5 wheel pattern and spacers in the front and I would imagine a kit like this would be stronger than the unit bearings which would help with wheel that have very little back spacing. But then again let's say I sell the PR44 for $3k and have the $2k from not getting the kit, I'm only $2.5k from a PR60 front, which would probably be stronger all the way around and have bigger brakes.
