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

Upper arm bulkheads in alloy for TT02

These alloy front and rear upper arm bulks are supplied as 1pr (2 pcs) for the TAMIYA TT02 chassis and replace the original plastic bulkheads. They provide a firmer anchor for the upper suspension link on both front and rear assemblies.

Manufactured to align with TT02 mounting points, the bulks install as direct-fit hop-ups without chassis modification in typical setups. The firmer mounting point helps the upper link retain its geometry under braking and cornering, aiding consistent setup adjustments on the track.

Installation uses standard TT02 mounting routines and can employ existing hardware when appropriate. Reuse intact screws and ball studs, avoid excessive torque, and check wheel toe and link free-play after installation. Regular inspections should focus on thread condition and confirming torque after initial runs.
