Model builders who want to dial in their scale rigs will find the Tamiya 56559 Ball Bearing Set a useful upgrade. Made specifically for 1/14 scale 4x2 tractor trucks, these bearings replace the kit metal bearings to reduce friction and lower drivetrain noise.
Swapping to these bearings typically yields smoother operation and a more responsive drivetrain. The set fits a variety of Tamiya items, including Item 56307.
