Any of the roller or ball bearing retrofits are going to have a defined life span, so they will have to be replaced at some point. Regardless of their advertising, roller bearings units also have no more load carrying capacity than a quality ball bearing unit, so they actually are no stronger or resistant to wear. LN has also recently increased their suggested replacement for their ceramic hybrid bearings to 75K miles.

If you want to get away from having to look at retrofits and maintenance items, consider the IMS Solution, which is an oil fed solid bearing, and is a permanent, life of the engine retrofit. We are doing more of them than ever now that the Solution is available in a dual row design as well.
