TAMIYA TT01 Front Lower Arm Upgrade Aluminium TT055 by GPM  [TT055]

Aluminium front lower arm for TT-01 chassis

This aftermarket front lower arm is designed as a direct aluminium swap for the stock plastic piece on the TAMIYA TT01. Built from aluminium alloy, the arm increases structural consistency while using the original TT-01 attachment points.

Use case: the alloy lower arm stabilises the front pickup, helps keep camber and toe settings stable under load, and gives a solid starting point for setup work using the supplied shims and collars. It is intended for maintenance, replacement of worn parts, or basic tuning without altering chassis geometry.

Fitment procedure: remove the factory arm with common hobby tools, transfer compatible fasteners, mount the arm to factory ball studs and hubs, and use the provided collars and shims to eliminate endplay and refine steering geometry. Double-check clearances and thread engagement prior to operation.

Service tips: check the arm after impacts for any distortion, keep mounting pivots clean and lightly lubricated where appropriate, and use shim adjustments to even out minor side-to-side differences.
