TAMIYA TT-02 Type-S Suspension Upper Arm Pivot Set JR-TT2S01-LB by Jazrider  [JR-TT2S01-LB]

TT-02 Type-S upper arm mount upgrade in aluminum

This aluminium upper arm mount set is manufactured for the TAMIYA TT-02 Type-S chassis and is labelled JR-TT2S01-LB. It replaces the stock plastic upper arm mounting points to create a firmer anchor for suspension arms, reducing local flex at the interface and promoting a more consistent reaction from the suspension during spirited driving or precision tuning.

Fitting to a TT-02 Type-S is commonly a straight replacement: remove the original mounts, seat the aluminium mounts in the existing chassis positions and reinstall the upper arms and fasteners. Make sure mounts are aligned and that bolts are tightened evenly to prevent preloading bearings or distorting suspension geometry. This item is an aftermarket accessory and does not alter the chassis beyond swapping the mounting points.

In setup terms the aluminium mount set shifts behaviour toward increased local stiffness and repeatability at the arm pivots. This can help the car hold camber and toe under load and sharpen steering response, though it can also pass more vibration into the chassis compared with softer plastic mounts. Use this upgrade when you want firmer, more consistent handling across runs.
