The Arrowmax AM-910013 is a 2.0mm mid-mounted topdeck produced as an aftermarket tuning component for XRAY T4 MID chassis layouts. It influences chassis flex and longitudinal rigidity to help tune handling balance through corners.
Installation replaces the original topdeck using the T4 MID mounting pattern; keep your existing hex fasteners and confirm there is no contact with radio equipment or linkage geometry. Perform a dry fit to check clearance from the motor, ESC and shock towers before tightening.
Using a thicker 2.0mm topdeck reduces torsional flex relative to thinner options, which can stabilise the car at speed but alter traction on low-grip surfaces. Combine this part with shock and anti-roll adjustments when refining handling.
Use this mid 2.0mm topdeck to alter chassis stiffness on XRAY T4 MID cars; always verify fitment and screw engagement before track running.
