Coming from RPM and made for the Arrma Typhon 4×4 3S BLX is a set of replacement A-arms. RPM’s versions are more adjustable, more durable and 5g lighter than stock. The designers added a second shock mount to the outside of the original stock shock mount, adding adjustability and improving trackability. The outer shock mount lowers the ride height, increasing stability on all surface types. A lower ride height also means faster corner speeds. Moulded from engineering grade nylons, the arms are a lot more durable than the standard parts with the redesigned shape of the A-arms help improve survivability during severe bashing. The arms come in sets of two and they are a direct fit.
