This aluminum rear upper suspension arm set fits TAMIYA Hotshot and Super Hotshot 1/10 electric buggies and is sold under model JR-THS05-BK. The components replace the stock rear upper arms and are finished in black anodized aluminum to reduce flex compared with plastic originals.
The kit influences suspension geometry by stiffening the rear arms, which can help maintain toe and camber settings more consistently during use. The parts use factory mounting points in most installations and will often accept the original hinge pins and compatible fasteners when dimensions match.
As with all hop-up components, treat these arms as one element of suspension setup; they change compliance but do not replace shocks or springs. Confirm fitment with uprights, linkages and check for gearbox or body mount interference before completing installation.
A targeted upgrade for classic Hotshot platforms where reduced flex and repeatable rear geometry are desired; verify any hardware requirements and final fit prior to installation.
