TAMIYA Thunder-series Aluminum Lower Arms Upgrade (Front/Rear) JR-TFD05-LB by Jazrider  [JR-TFD05-LB]

Stiffer lower arm upgrade

The JR-TFD05-LB set of aluminum front and rear lower suspension arms is designed as an aftermarket upgrade for TAMIYA Thunder Shot, Thunder Dragon, Fire Dragon and Terra Scorcher buggies. Sold as a pair, the parts replace the stock lower arms to provide a metal option where increased stiffness is wanted for repeatable handling.

These arms are specifically for the chassis listed above and are intended for hobby buggy use only. The blue coating makes the parts easy to identify during maintenance.

Fitment advice: the replacement arms use the same mounting points as the original components on compatible TAMIYA chassis and interface directly with the hub and suspension geometry. After installation, verify full suspension travel and check for any rubbing against adjacent components.

Setup note: fitting aluminum lower arms lessens flex at the mount and can alter steering characteristics and mid-corner behavior; tune shocks and wheel alignment progressively to restore the preferred balance.

JR-TFD05-LB arms are a practical aluminum upgrade for the Thunder-series buggies to achieve firmer, more consistent suspension behavior; always confirm compatibility with your specific chassis variant.
