TAMIYA Hotshot, Hotshot II/2 & Boomerang 4WD Front Lower Arms Precision Alloy - JR-THS06-GU by Jazrider  [JR-THS06-GU]

Front lower arms: product summary

The JR-THS06-GU aluminium front lower suspension arm kit from JAZRIDER is an aftermarket replacement intended for TAMIYA Hotshot, Hotshot II/2 and Boomerang 4WD chassis. Swapping in alloy arms in place of the factory plastic items produces a firmer mounting location that helps preserve correct suspension geometry while resisting wear.

This item is compatible only with the chassis listed and is supplied for model-scale use. During installation, carry out an initial dry assembly to confirm ball-stud and hinge-pin alignment, check bearings and pivot pins for wear, and verify unobstructed suspension travel. Minor trimming of paint or flash on contact surfaces will often aid a neat fit.

From a handling viewpoint, aluminium lower arms reduce flex versus stock plastic which can give a snappier steering response and steadier camber during cornering. As the front stiffness changes, small adjustments to other suspension elements such as roll centre or anti-squat may be needed to re-establish the desired balance.

Ideal for modellers replacing tired plastic arms or those seeking a firmer front end for refined handling, these alloy arms are a direct-swap upgrade that supports incremental suspension tuning.
