Ball Bearing Set 1150, RC car accessory, 16 pcs

The Ball Bearing Set 1150 brings a focused drivetrain upgrade to compatible R/C car chassis by replacing plastic bushings with 16 metal bearings sized at 11 x 5 x 4 mm. Each bearing supports smoother rotation at key moving points, helping the transmission run with less drag during acceleration and steady laps. This set is intended for a straightforward tuning change that targets friction where axles and drivetrain parts turn under load. In compatible entry level platforms, the swap can help reduce power loss through the driveline while also supporting the longevity of axle joints. The pack provides enough bearings for several listed chassis layouts: DT-03 and DT-02 require 14 bearings, while WR-02, WR-02G and WT-01 require 16. That fitment detail makes the set useful both for a complete replacement on some chassis and for a near-complete conversion on others. On the bench, the compact 1150 format suits builders refining a buggy or wheelie platform with a practical mechanical upgrade rather than a cosmetic change. It fits naturally into maintenance work, rebuilds and fresh kit preparation where smoother rolling parts and more efficient drivetrain movement matter most.
