Yokomo BD9 FWD Rear Topdeck 2.0mm Tuning Part Arrowmax AM-920024  [AM-920024]

BD9 FWD Rear Topdeck for Chassis Setup

This Arrowmax AM-920024 rear topdeck is supplied as a replacement rear section for the Yokomo BD9 FWD mid-profile topdeck. It fits BD9 chassis that require a steady rear datum for suspension and balance setup work.

As a tuning element, the topdeck changes overall chassis stiffness and alters the flex split between front and rear ends. Installing the rear topdeck helps keep shock tower mount positions and servo link geometry consistent, so you can pursue roll centre and traction adjustments without touching main chassis plates.

Installation notes: the part replaces the factory rear topdeck segment and mounts to the original screw locations on the BD9 rear assembly. During fitting, check shock tower alignment and battery tray positioning, ensure the motor and driveshafts have clearance, and re-torque mounting screws after initial track running.
