For model racers chasing repeatable drivetrain behaviour, the Serpent 500124 - SRX2 RM Transmissioncase Insert Set is a tidy solution. The inserts help lock bearing positions and keep shafts running true under varying track conditions.
By limiting side-to-side movement and supporting correct gear engagement, the inserts reduce uneven wear and can cut down on the need for frequent shimming. They suit regular maintenance cycles and competitive servicing alike.
