This GPM rear gear box is designed to reinforce the ARRMA KRATON 8S rear assembly, reducing movement at the differential, dampers, anti-roll bar and knuckle arms. The unit is built from 6061 T6 aluminium to deliver a durable, dimensionally stable mounting solution for hobbyist and competition use.
The 6061 T6 aluminium construction improves structural rigidity and thermal behaviour versus typical plastic housings, helping to keep mechanical clearances stable during heavy use. This upgrade is intended for builders who require a robust, long lasting rear mounting platform for the ARRMA KRATON 8S.
