TT02 Front and Rear Upper Arm Bulk Alloy Upgrade - TT2008 by GPM  [TT2008]

High-strength alloy upper arm bulk for TT02

This pair of alloy upper arm bulks fits the TAMIYA TT02 chassis and is supplied as 1pr (2 pcs). They replace the stock plastic bulkheads to provide a firmer mounting point for the upper suspension link on both front and rear assemblies.

Made to match TT02 mounting locations, these parts install as a direct-fit hop-up without trimming the chassis. In tuning terms they stabilise the upper link anchor and help keep suspension geometry consistent under load, which aids repeatable setup during track runs.

Fitment follows standard TT02 procedures and uses existing hardware where suitable. Inspect and reuse original screws, ball studs and spacers if they are sound, avoid over-torquing fasteners, and verify wheel alignment and link free-play after installation. Routine upkeep is limited to checking thread condition and re-torquing after the initial outings.
