TAMIYA BB-01 Rear Swing Arm Pull Rod 7075 Alloy BBX05657 by GPM  [BBX05657]

7075 alloy rear swing arm pull rod for BB-01

This aftermarket rear pull rod is made for TAMIYA BB-01 chassis and manufactured by GPM as BBX05657. Fabricated from 7075 alloy, the part balances strength and weight and keeps the original ball-post footprint so it mates with existing suspension link geometry.

The rod features a curved contact geometry at the steel pivot ball to help retain the ball under load and reduce unintended disengagement. With a hard-anodized surface on the 7075 alloy, the component is intended to deliver predictable pivot behaviour and steadier rear feedback during aggressive runs.

Installation is straightforward: swap the stock rear pull rod on a BB-01, ensure proper ball-post alignment and thread engagement, then tighten to the recommended torque. As a tuning upgrade this rod can influence rear roll centre and responsiveness, so verify clearances and carry out progressive testing to assess handling effects.
