RPM B4 series front A-arms & bulkhead
The RPM front A-arms and bulkhead set is designed for all Team Associated B4 series vehicles including the newer B4.1 and B4.2. The wishbones sport an updated design with the hinge pin retaining screws now sitting in-line with the pins to overcome structural weakness issues associated with the original design. The arms are also a lot beefier that the stock items and come moulded in RPM’s genuine nylon compound for added rigidity. They are made to retain the stock geometry and also include a suitable front bulkhead.
