Upgrade for TAMIYA TT-02 Type-S: Aluminum Upper Arm Pivot Set JR-TT2S01-LB by Jazrider  [JR-TT2S01-LB]

Upper pivot mount upgrade for TT-02 Type-S

The product is an aluminum upper arm mount set intended for the TAMIYA TT-02 Type-S chassis and carries model number JR-TT2S01-LB. It takes the place of the factory plastic mounts to provide a more rigid attachment for upper suspension arms, aiming to cut down on localized flex and yield a steadier suspension response while driving aggressively or when tuning handling characteristics.

On a TT-02 Type-S the swap is typically direct: remove the existing mounts, locate the new aluminum mounts into the current chassis mounting points and refit the arm hardware. Ensure correct alignment and uniform fastener tension to prevent bearing preload or unintended suspension geometry change. This component is an aftermarket accessory and does not modify chassis geometry beyond the mount swap.

For tuning, this mount set biases the system toward higher local stiffness and predictability at the arm pivots. It can help hold camber and toe under load and make steering inputs more immediate, though you may notice an increase in vibration transfer versus stock plastic mounts. Choose these mounts when you want firmer feedback and consistent lap-to-lap behaviour.
