Swap in the GPM aluminium rear gear box to tighten up the rear mounting points on an ARRMA KRATON 8S. By stabilising the differential, dampers, anti-roll bar and knuckle arms, this part helps reduce slop and improves steering predictability across rough surfaces.
The 6061 T6 aluminium construction gives this gear box better thermal conductance and tighter fitment compared with plastic alternatives. That means less movement under load and a longer lasting rear assembly for bashing or trail runs.
