This red anodized aluminum rear upper suspension arm is an RC-scale replacement designed for TAMIYA TL-01, GF-01 and WR-02 platforms. It is supplied as a direct-fit tuning component that uses the original rear upper arm mounting points and does not change the chassis or tower geometry.
The alloy construction reduces flex compared with common plastic arms and delivers a more consistent pivot surface during cornering and acceleration. Fitment assumes existing chassis layout and hardware are retained so the arm can be installed without cutting or drilling the main chassis.
Practical installation notes: swapping to aluminum often tightens rear response, so verify toe, camber and shock settings after fitting and make small incremental changes to rebound or spring rates to recover your preferred balance. This product is for RC-scale use only and is not intended for any real vehicle application.
