The aluminium rear upper chassis link is designed for Axial Racing Yeti models that use the AX31109 layout and carries model code YT014R. It acts as the upper attachment between the chassis and rear suspension arm, suitable for scale trail and rock crawler setups.
Aluminium construction reduces flex compared with the standard plastic part, maintaining alignment under load and delivering a more consistent feel when you tweak rear suspension geometry. The component installs as a direct-fit where AX31109 points are present.
Replacing the stock upper link with a stiffer metal item affects roll centre and anti-squat settings, which can improve traction or change rear stability depending on other setup choices. Use the existing Yeti mount points and follow normal link replacement procedures.
For AX31109-configured Yeti drivers, the aluminium rear upper chassis link provides a durable replacement or upgrade to tighten rear-end geometry for technical driving.
