Tamiya TT02 Front Adjustable Alloy Upper Arm by GPM TT2054  [TT2054]

Front adjustable upper arm for TT02

This alloy front adjustable upper arm is an aftermarket replacement designed for use on the Tamiya TT02 chassis, intended to give builders a metal alternative to the stock plastic arms and a means to fine-tune front suspension geometry. The part focuses on stability and predictable changes to steering and camber when you alter linkage or mounting positions.

The component provides adjustable mounting points that let you alter camber and roll-center without modifying the bulkhead or uprights. That makes it useful for drivers seeking small, repeatable setup changes on carpet, asphalt, or club tracks where precise front-end behavior matters.

Installation is straightforward for experienced hobbyists: remove the stock arm, transfer any necessary pins or hardware, and secure the alloy arm using the stock mounting points. Verify alignment and steering travel after installation and check for clearance against the steering linkage and uprights during full lock.

Routine maintenance is limited to checking mounting screws for tightness and inspecting for wear at the pin interfaces; if you use different ball studs or turnbuckles, re-check geometry after each change. Alloy construction can reduce flex compared with plastic arms, so expect tuning changes to be more immediate and noticeable.

This arm is suited for TT02 builders who want a durable alloy alternative for front suspension tuning, enabling clearer feedback from setup changes and consistent behavior lap after lap.
