The GPM SCX2031R is designed as a robust aluminium rear body post mount to enhance the interface between the body shell and chassis on AXIAL SCX10 II platforms. It is intended to provide a stable, repeatable mounting point that reduces body movement while maintaining correct alignment with existing body posts on AX90046 and AX90047 models. Installation is straightforward and suitable for tuners seeking a durable metal upgrade over the stock plastic posts.
