This alloy rear chassis brace is supplied as model EX013A for compatibility with Axial EXO rear chassis mounting points. It is a precision-fit replacement intended to offer added structural support and to allow controlled adjustment of chassis flex for tuning and maintenance. The wording stresses accurate fitment and tuning role rather than specifying performance gains.
Installation requires standard RC hand tools: align the brace to the rear chassis mounts and secure using the existing fastener locations. The component modifies rear-end stiffness and therefore should be considered as part of a wider setup change when fine tuning suspension behaviour.
Use this part only as an RC model accessory. Inspect mount alignment and thread engagement during assembly and re-check fastener security during initial shakedown to verify expected chassis response.
