TAMIYA Hotshot/Hotshot II/2/Boomerang 4WD Aluminium Front Lower Arms JR-THS06-GU Upgrade by Jazrider  [JR-THS06-GU]

Durability-focused front lower arm description

The JR-THS06-GU aluminium front lower suspension arm kit is an aftermarket replacement from JAZRIDER for TAMIYA Hotshot, Hotshot II/2 and Boomerang 4WD chassis. Replacing the factory plastic arms with aluminium produces a tougher mounting component that better resists wear during prolonged running while keeping the original suspension geometry.

Compatibility is limited to the listed TAMIYA models and this unit is intended for model-scale applications. During fitting, perform a preliminary assembly to check ball stud and hinge-pin alignment, assess bearings and pins for wear, and confirm unrestricted suspension travel. Removing minor paint or flash from contact faces helps ensure a clean installation.

As a durability upgrade, aluminium lower arms cut down on flex found in stock parts, giving a more stable front end under load. This change can alter handling balance, so small adjustments to roll center or anti-squat settings may be useful to maintain desired steering characteristics.

For modellers replacing fatigued plastic components or aiming for a longer-lasting front end, these aluminium arms offer a direct-replacement option that supports ongoing suspension tuning.
