GPM Tamiya TT02 Front Adjustable Alloy Upper Arm TT2054 - Upgrade Part  [TT2054]

Aftermarket front upper arm for TT02 setups

This alloy front adjustable upper arm is an aftermarket upgrade for the Tamiya TT02 chassis that replaces the standard plastic arm with a stiffer alloy unit, helping drivers tune front suspension geometry with more confidence. It aims to deliver predictable changes when you alter link positions.

Adjustable mounting holes let you alter camber and roll-center without modifying the bulkhead or uprights, which is useful when refining setup on asphalt, carpet, or small club circuits where consistent steering balance is required.

Installation is straightforward for experienced hobbyists: remove the stock arm, transfer necessary pins or hardware, and mount the alloy arm to the original points. After fitting, verify wheel alignment and check for any binding at full steering lock.

Maintenance is focused on routine inspections of screw torque and pin interfaces; if you fit different ball studs or turnbuckles, re-check geometry after each change. The alloy option reduces arm flex compared with plastic so tuning moves show up faster.

A solid upgrade for TT02 enthusiasts seeking more precise front-end feedback and reliable setup adjustments session to session.
