Upgrade for Tamiya Hotshot Rear Knuckle Arms, Machined Aluminum - JR-THS02-RD by Jazrider  [JR-THS02-RD]

Hotshot chassis rear knuckle replacement

This set of machined aluminum rear knuckle arms is offered as a hop-up replacement for Tamiya Hotshot and Super Hotshot models. The stiffer alloy mounting point reduces deformation compared with stock plastic, helping the suspension keep its intended geometry through rough landings and aggressive driving.

Fitting is a direct replacement using the Hotshot rear suspension mounting points in most cases. Verify part orientation, hub clearance, and driveshaft range of motion before final torqueing to avoid binding during full suspension travel.

From a tuning viewpoint, these arms are intended to limit hub flex to increase rear stability and crispness in steering. Combine with shock tuning, tyre selection, and toe settings to refine balance; apply changes stepwise and evaluate on a controlled surface.
