Rear Lower Suspension Arms (Aluminum) for Tamiya Hotshot JR-THS07-BK by Jazrider  [JR-THS07-BK]

Rear lower arm upgrade for Hotshot buggies

These rear lower suspension arms are a machined aluminum hop-up designed for Tamiya Hotshot and Super Hotshot chassis. With a black finish and precise tolerances, the arms are a direct replacement for stock rear lowers to increase rigidity and improve suspension consistency.

Switching to aluminum lowers focuses on chassis-level improvements: reduced flex at mounting points helps the suspension maintain shock and geometry settings under dynamic load. The parts are intended for hobby RC use only and fit the rear lower mounting points on Hotshot-series Tamiya chassis without altering the intended suspension geometry when installed correctly.

Installation notes: remove the OEM rear lower arms from the hinge pin and mounting posts, place the aluminium arm into the same mounting locations, and secure with the original hardware. Check hinge-pin alignment and suspension travel after installation before running the model. No further chassis modification is required for standard Hotshot and Super Hotshot layouts.

Choose these arms when you want a firmer rear end and more repeatable suspension behavior for practice days or club competition on the Hotshot platform.
