This set provides a direct replacement for the front and rear upper arms used on chosen TAMIYA 1/10 buggies. Manufactured as part number JR-TFD04-GU from aluminium and finished in gun metal, the arms are intended to be a firmer substitute for the stock plastic items.
Installation follows standard arm-swap steps: remove old arms, inspect and where possible reuse existing pins and clips, fit the new aluminium arms and verify suspension travel and pivot action. Replace any worn hardware to ensure secure mounting.
For setup, expect improved consistency when changing shock rates or altering toe since the aluminium arms limit unwanted flex, making small tuning changes more reliable.
