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

CNC-grade style adjustable upper arm for TT02

This alloy front adjustable upper arm is an aftermarket replacement engineered for the Tamiya TT02 chassis, providing a stiffer metal alternative to the OEM plastic arm and enabling precise adjustments to front suspension geometry for track-focused setups.

Engineered with multiple mounting locations, the arm allows systematic camber and roll-center adjustments without modifying the bulkhead or uprights, giving tuners repeatable setup options for different surfaces and racing conditions.

Installation follows standard procedure: remove the factory arm, transfer any required pins and hardware, and secure the alloy arm to the stock mounting points. After fitting, perform alignment checks and verify steering travel and clearance across the full range.

Service procedures include routine torque checks on fasteners and inspection of pin interfaces for wear; when fitting different ball studs or turnbuckles, revalidate geometry. The alloy construction reduces flex relative to plastic, resulting in more direct feedback to setup changes.

A precision upgrade for TT02 builders seeking consistent, tuneable front-end characteristics and reduced component flex.
