These aluminium front upper suspension arms are made for Tamiya Hotshot family 4WD models and are supplied as part JR-THS04-LB. They replace the original plastic components to offer a stronger mounting location and more predictable front suspension behaviour on the specified chassis.
Install the arms to stiffen the front linkage for tuning or to renew worn plastic parts. The arms keep the factory mounting geometry so they mate with existing suspension towers and steering knuckles, and screw interfaces follow original dimensions to avoid chassis modifications.
For modders wanting steady front-end performance, these aluminium arms provide a reliable hardware swap that preserves stock fitment; always confirm correct screw torque when fitting to avoid damaging threads.
