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

Rear knuckle arms for Hotshot chassis

This aluminum rear knuckle arm set is offered as an RC-scale replacement and hop-up for Tamiya Hotshot and Super Hotshot chassis. Machined aluminum provides a stiffer mounting point than typical plastic knuckles, helping maintain geometry under load during jumps and rough surfaces while keeping the part focused on model-level performance.

Installation generally replaces the stock rear knuckle arms and uses existing mounting points on the Hotshot-series rear suspension. Check fitment against the stock parts before final assembly, verify the range of motion around the hub and driveshaft, and confirm clearance for wheel hexes and suspension travel.

As a tuning component, these knuckle arms are intended to alter steering feel and rear-end stability by reducing flex at the hub. Use them alongside tyre, shock, and toe adjustments to tune handling; observe changes incrementally and test on a controlled surface to assess effects on traction and turn-in.
