TAMIYA BB-01 Rear swing arm pull rod 7075 aluminum by GPM BBX05657  [BBX05657]

Aluminum rear pull rod for BB-01

This aftermarket rear swing arm pull rod is made for TAMIYA BB-01 scale RC use and manufactured by GPM as BBX05657. The part uses 7075 aluminum for a balance of tensile strength and weight control, and the profile matches the original ball-post location so it integrates with existing suspension link geometry.

The rod features an arcuated shape at the steel pivot ball interface, which helps retain the pivot ball in its seat during dynamic movement and reduces unwanted disengagement. That shape, combined with the hard-anodized 7075 aluminum, is intended to deliver consistent pivot behaviour and steady feedback through the rear suspension under aggressive RC driving.

For installation, replace the stock rear pull rod on a BB-01 chassis and confirm ball-post alignment and thread engagement before final tightening. As a tuning item, this rod can affect rear roll centre and responsiveness; check alignment and clearances after fitment and test incrementally to assess handling changes.
