This is an RC-scale upgrade set of front and rear upper suspension arms made of aluminum, supplied as 2 pcs in red, designed for Tamiya Thunder Shot, Thunder Dragon and Fire Dragon chassis. The parts replace the stock plastic upper arms to provide a more consistent mounting point for the suspension geometry and to reduce flex under load.
Installation is intended as a direct replacement on the listed Tamiya models, using existing fasteners and linkage hardware where compatible. Inspect the fit at each attachment point before final tightening and reuse stock ball studs and pins unless upgraded hardware is specified by your chassis manual.
These arms serve a tuning role rather than an electronic or drivetrain upgrade, helping to stabilise roll characteristics and maintain camber during cornering when paired with appropriate shock and tyre setup. They are sold as a pair and intended strictly for RC buggy use.
