The Tamiya 54997 Hornet Full Ball Bearing Set is a simple, effective swap for older Tamiya buggies. Replacing stock plastic bushings with sealed ball bearings reduces mechanical drag, improving drivetrain efficiency and often yielding longer battery runtimes on a single charge.
This bearing kit has been made to suit a range of classic chassis and vintage kits, such as:
Ball bearings lower contact friction in the drivetrain compared to plastic bushings, which leads to smoother rotation, reduced wear on moving parts, and a cleaner feel when driving. This makes the 54997 set a practical maintenance and performance step for hobbyists preserving vintage models.
