Improve the drivetrain resilience of an ARRMA KRATON 6S EXB with the GPM MKV61034S/2 assembled front and rear differentials. Gears are produced in 20CrMnTi steel while housings use 7075 aluminium alloy, delivering stronger wear resistance. The helical gear set runs a 10T/34T ratio with a 1.3mm module for smooth engagement, and the 29mm differential shell helps maintain gear alignment under hard acceleration. Differential oil is not supplied; install the correct type and volume as instructed in the ARRMA manual.
