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

Aluminum rear knuckles for Hotshot and Super Hotshot

These machined aluminum rear knuckle arms serve as a durable replacement and performance hop-up for Tamiya Hotshot and Super Hotshot chassis. Precision machining yields a firmer hub mounting point than stock plastic parts, helping preserve suspension geometry during jumps and rough terrain while delivering a model-level strength improvement.

Installation typically replaces the OEM rear knuckle arms and uses the existing mounting points on the Hotshot-series rear suspension. Before final assembly check alignment, confirm the range of motion around the hub and driveshaft, and verify clearance for wheel hexes and full suspension travel.

Used as a tuning item, the stiffer knuckles reduce hub flex to tighten steering feel and stabilise the rear under load; combine them with tyre choices, shock damping, and toe adjustments to dial in handling. Make setup changes incrementally and test on a controlled surface to evaluate effects.
