Tamiya Hotshot/Super Hotshot Rear Knuckle Arms Aluminum Reinforced JR-THS02-GU by Jazrider  [JR-THS02-GU]

Aluminum rear knuckles for Hotshot models

This aluminum rear knuckle arm set is made for Tamiya Hotshot and Super Hotshot chassis as a metal alternative to the original plastic knuckles. The gun metal finish keeps a consistent look while the aluminum construction reduces flex where the rear hub and suspension pivot join.

Installation uses the vehicle's existing rear hub hardware and mounting points, so the factory knuckles can be swapped out without modifying the chassis. These parts are intended as a direct upgrade to increase durability and provide a firmer rear mounting point for the hub and suspension assembly.

From a setup viewpoint these knuckle arms create a stiffer interface between the rear hubs and suspension, which can alter rear-end feel during acceleration and cornering when combined with other changes. They suit drivers seeking a metal backup to plastic components for track or aggressive off-road use while preserving the original geometry.
