The 3RACING TA05-27 18-piece ball bearing set replaces worn bushings on the Tamiya TA05 to create a quieter, freer-running drivetrain. By cutting friction, bearings help the car respond more predictably and reduce heat buildup in moving parts. This upgrade is popular among builders who want tidy mechanical efficiency.
Ball bearings minimise contact resistance and produce steadier rotation under load, which aids acceleration and reduces component fatigue. For many TA05 owners, the switch offers a noticeable improvement in rolling performance without complex modifications.
Start with a clean chassis and carefully remove existing bushings. Press the new bearings in squarely and confirm shafts spin freely with no binding. Recheck after a short run to ensure bearings have seated correctly and there is no lateral play.
