TAMIYA Hotshot Aluminum Rear Lower Suspension Arms Upgrade for Suspension Tuning - JR-THS07-RD by Jazrider  [JR-THS07-RD]

Rear arm performance overview

These rear lower arms are aluminium replacements finished in red anodize, made to fit TAMIYA Hotshot and Super Hotshot chassis. The upgrade focuses on reducing flex at the rear suspension pivot to deliver a more consistent response than standard plastic arms.

Installation is mechanical: remove the stock lower arms and swap in the aluminium pieces using the existing mounting points and hardware. The parts retain factory geometry to simplify fitment for hobbyists familiar with Tamiya layouts.

With the stiffer arms in place, changes to camber, toe, spring rate, or anti-roll bars become easier to evaluate since the arms are less likely to mask other setup adjustments.

Ideal for racers and tuners seeking a stable, durable rear lower arm to support predictable handling on Hotshot-series buggies.
