Yokomo BD9 FWD Topdeck 2.0mm Front by Arrowmax AM-920023  [AM-920023]

Front topdeck for BD9

This Arrowmax AM-920023 front topdeck is an RC-scale replacement part designed for the Yokomo BD9 FWD touring chassis. The 2.0mm thickness and aluminium construction provide a discrete way to alter front-end stiffness without changing major suspension components.

Fitment focuses on the BD9 front section, where the topdeck ties the shock tower and bulkhead areas together. Installation requires basic disassembly of the front chassis stack and the removal of existing topdeck fasteners, then reusing original mounting points to secure the Arrowmax piece. No additional hardware is required beyond standard hex screws used on the BD9.

In tuning terms, changing to a 2.0mm aluminium front topdeck affects chassis flex and steering feel; expect a firmer front response compared with thinner or composite topdecks. Use this part as part of incremental setup changes, testing one variable at a time to evaluate handling effects on typical 1/10 electric touring car tracks.
