Tamiya TT02B Alloy Front Lower Arm TT2B055 Technical Upgrade by GPM  [TT2B055]

Precision alloy front lower arm for TT02B

This front lower arm pair is manufactured as an alloy upgrade for the Tamiya TT02B platform, aimed at hobbyists seeking reduced flex and more repeatable suspension response. The components are supplied as a single pair for 1/10 touring car use and are intended to replace the standard plastic arms.

Fitment details: compatible with standard TT02B suspension assemblies. Installation uses the existing hinge pins and fasteners; attention to ball stud seating and hinge pin alignment is important to preserve steering geometry and avoid binding.

Engineering notes: the alloy arm increases local torsional stiffness at the suspension pickup, altering load distribution during lateral and longitudinal events. This affects how the shock package and springs react, so consider incremental changes to shock valving and spring rates when evaluating handling. Inspect mounting points for wear and verify clearance with steering links after installation.

Use TT2B055 as part of a measured setup approach, checking geometry and component wear to ensure consistent handling performance on TT02B builds.
