This is the Yokomo B9-32UA19A upper bulkhead (A) intended for BD9-family RC touring chassis. Supplied as 1 pcs, it is suitable for the front-left position or the rear-right position depending on chassis variant.
Install this bulkhead when replacing a damaged upper mount or when switching suspension geometry during setup. It locates the upper arm and provides the mount for suspension links, so ensure correct left/right orientation and part-code match prior to tightening fasteners.
Confirm chassis code against the compatibility list, verify left/right placement, inspect link geometry and fasteners after fitment, and carry out a static function check before running the car.
