Community Feedback:

Owners of small-scale Losi vehicles commonly replace these bearings during routine maintenance, especially after heavy use in dusty or high-impact environments. Users report improved drivetrain smoothness and reduced resistance after installing fresh bearings. Many hobbyists keep spare bearing sets on hand, as they are one of the most frequently replaced wear items in compact RC platforms.
