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

Rear knuckle arms for Hotshot series

This aluminum rear knuckle arm set from JAZRIDER is produced for Tamiya Hotshot and Super Hotshot chassis to provide a metal replacement for common plastic rear knuckles. The gun metal finish gives a consistent aesthetic while the aluminum construction reduces flex where the rear hub and suspension pivot load converge.

Installation is intended to use the vehicle's existing rear hub hardware and mounting points, replacing the factory knuckles without modifying the chassis. The parts serve as a straightforward upgrade to increase durability and create a firmer rear mounting point for the hub and suspension assembly.

In tuning terms these knuckle arms act as a stiffer interface between the rear hubs and suspension, which can change the rear-end feel under acceleration and cornering when combined with other setup changes. They are suitable when you want a metal backup to plastic components for track use or more aggressive off-road running while maintaining original geometry.
