The GPM MAI040RAN is a precision 7075 aluminium rear body post fixed mount engineered to improve structural stability on ARRMA INFRACTION 6S BLX platforms. With a focus on strength and repeatable fit, the CNC machined 7075 material reduces rear shell deflection under load and offers superior wear resistance compared with standard plastic posts. It installs in the ARRMA 1/7 4WD chassis with no modification and provides a robust mounting point for repeat high speed operation.
