The ARRMA KRATON 6S EXB thrives on tough tracks and open paddocks. The GPM MKV61200S gear set, made from 20CrMo steel, is meant to resist repeated shocks and heavy loads while keeping your drivetrain consistent in extreme use.
These gears are produced with precise tooth geometry to promote even load distribution and lower long term wear. The kit includes reinforced steel cross shafts that help maintain gear alignment under load for steady acceleration and corner exits.
Designed for 29mm differential cases, this set supports both limited slip and open differentials. It is a direct way to refresh worn internals or strengthen a truck for frequent rough use.
