These blue-anodized aluminum suspension arms are intended for the Tamiya TA07 and TB04 Pro II platforms and reference the 9008169 part. They replace the original plastic arms to provide a more rigid option for consistent suspension behavior.
Fitment advice: the arms are designed to use the TA07/TB04 Pro II mounting points and original hinge pins and mounting hardware. Confirm hinge-pin alignment and ball stud positioning during installation to preserve the chassis' suspension geometry. No extra changes to electronics or drivetrain should be needed.
Performance notes: alloy arms increase front-end stiffness, which can enhance steering precision but reduce passive compliance. Tuning with springs, dampers, and anti-roll bars will help integrate the change into your overall setup.
