JAZRIDER JR-THS06-LB front lower arms are a purpose-made aluminium replacement for Tamiya Hotshot, Hotshot II/2 and Boomerang 4WD. They are intended to reduce component replacement frequency and provide a firmer mounting point for the front suspension assemblies.
These blue aluminium arms increase rigidity at the suspension pivot compared with stock plastic parts, which reduces flex under load and helps maintain more consistent steering feedback during repetitive impacts. The result is improved part longevity and predictable handling for routine hobby use.
The arms are machined to match factory mounting locations so they fit without hardware modification in most cases. Routine checks of pivot pins and bushings after installation are recommended to ensure correct operation and service life.
