Yes they are worth it.
It would not be the first upgrade I would make... but they are worth it.
1. The larger outter bearing holds up much better as the larger Short Course wheels put alot of stress on the outter bearing and the stock on in the plastic hubs does not last long under these conditions.
2. Having the aluminum hubs are still and help you suspension work better and flex less.
3. Having the tunability of changing the upper section for more adustment holes is great if you find yourself changing tracks and tuning alot for different conditions.
Are they spendy... Yes but I feel they are worth the investment.
