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

Replacement Rear Topdeck for BD9 FWD

Arrowmax AM-920024 is supplied as a rear topdeck replacement compatible with the Yokomo BD9 FWD mid-profile topdeck assembly. It is intended for enthusiasts who require a repeatable rear section for suspension and balance adjustments on their BD9 chassis.

Functionally, the topdeck modifies chassis stiffness and adjusts how flex is shared between front and rear. Fitting the rear topdeck solidifies shock tower attachment points and servo linkage geometry, enabling refinement of roll centre and traction without altering the bulkheads or main chassis plate.

Installation notes: this unit replaces the factory rear topdeck section and uses the BD9 standard screw positions for mounting. When fitting, ensure shock towers and battery tray are aligned, verify clearance for the motor and driveshafts, and re-check fastener tightness after an initial run to secure your setup.
