Maintaining smooth differential action starts with quality parts. The XRAY 930020 pack contains 24 steel balls of 2.4mm diameter, enough to rebuild two complete ball differentials using 12 balls each. These steel components are made to keep diff operation consistent and durable under normal hobby use.
Each ball in this set is manufactured to tight tolerances so your differential can run smoothly lap after lap. Whether you are tuning for race conditions or weekend bashing, using correctly sized steel balls helps minimise uneven wear and keeps driveline feeling predictable.
The standard 2.4mm size in this 24-piece set fits many 1/10 scale RC vehicles that use ball differentials, making it a handy spare parts kit for club racers and casual builders alike.
