GPM Tamiya TT02 Front Adjustable Alloy Upper Arm TT2054 - Chassis Option  [TT2054]

Front adjustable upper arm optimised for TT02

This adjustable alloy front upper arm is an aftermarket replacement for the Tamiya TT02 chassis that replaces the stock plastic option with a stiffer metal unit, giving drivers a firmer platform for setup changes. It helps make small adjustments more repeatable.

Multiple pickup points allow camber and roll-center changes without altering bulkheads or uprights, so you can refine handling for carpet, tarmac, or indoor club surfaces while keeping the original chassis intact.

Fitting is aimed at hobbyists comfortable with basic teardown: remove the OEM arm, move over any required pins or hardware, then fit the alloy arm to the factory mounting holes. After fitting, check wheel alignment and full-lock clearance against steering components.

Upkeep is minimal: check screw tightness and inspect pin bores for play; any change of ball studs or turnbuckles should be followed by a geometry check. The alloy build cuts flex versus plastic, so tuning results are more immediate.

Suitable for TT02 racers wanting a stronger front arm for consistent steering feedback and finer camber control during track sessions.
