This machined aluminium rear upper arm kit is intended as an aftermarket hop-up for Tamiya Hotshot and Super Hotshot chassis. Components are red-finished and produced to align with stock mounting points so they serve as direct replacements where geometry matches the original design.
Swapping to these aluminium arms reduces link flex versus plastic, promoting consistent suspension geometry while tuning. Installation generally mirrors the factory arm replacement steps and may permit reuse of original pins and fasteners when compatible; always confirm smooth suspension travel and clearances after fitting.
A reliable aluminium swap for enthusiasts targeting repeatable suspension behavior and improved setup control on classic Hotshot platforms.
