TAMIYA TT01 Alloy Front Lower Arm by GPM TT055  [TT055]

Alloy front lower arm for TT-01

This aftermarket front lower arm is produced by GPM for the TAMIYA TT01 platform and is intended as a like-for-like hop-up to replace standard plastic arms. Constructed from aluminium alloy, the part is positioned to add stiffness and consistent geometry under load while using existing mounting points on the TT-01 chassis.

Practical role: the alloy arm stabilises the front suspension pickup, helps maintain camber and toe settings through impacts, and provides a firmer baseline for further tuning with shims and collars. It is useful when adjusting ride characteristics or replacing worn plastic components without changing the chassis layout.

Installation notes: remove the original lower arm using standard tools, transfer any reusable hardware, fit the GPM arm to the factory ball studs and hubs, and use the supplied collars and shims to fine-tune endplay and steering geometry. Check thread engagement and rotating clearances after assembly and confirm alignment before first run.

Maintenance and tuning tips: inspect for deformation after crashes, keep pivot points clean and lightly greased if recommended by your maintenance routine, and use the included shims to correct minor asymmetries or to dial in steering response.
