TAMIYA BB-01 Rear Pull Rod 7075 Aluminum BBX05657 by GPM  [BBX05657]

7075 Aluminum rear pull rod for BB-01

This aftermarket rear swing arm pull rod is built for TAMIYA BB-01 RC chassis and manufactured by GPM as BBX05657. It uses 7075 aluminum to give high tensile strength while keeping weight low, and the outer profile matches the stock ball-post location so it integrates cleanly with existing suspension link geometry.

The rod uses a curved contact area where it meets the steel pivot ball to help retain the ball in its seat during dynamic movement, reducing the chance of accidental disengagement. That profile combined with a hard-anodized 7075 finish aims to provide steady pivot action and clearer rear-end feedback when driving hard.

For fitment, replace the factory rear pull rod on a BB-01 chassis and verify ball-post alignment and thread engagement before final torque. As a setup item this part can influence rear roll centre and responsiveness, so check clearances and perform incremental tests to dial in handling.
