This aluminium front lower arm set is manufactured for use on TAMIYA Hotshot, Hotshot II/2 and Boomerang 4WD chassis and replaces the original plastic components to improve rigidity and repeatable geometry for tuning sessions.
Tuning benefits: the stiffer arms help control steering inputs and limit flex during cornering, which can make suspension adjustments more predictable; review toe, caster and shock mounting settings after swapping materials to tune handling to your preference.
Installation guidance: supplied as direct-replacement parts that use the factory mounting points and existing hardware on the listed TAMIYA models. Remove the OEM arms, transfer any required shims or bushings, and follow standard assembly checks. Confirm fit and clearance before completing the installation.
Ideal when you want a dimensionally stable aluminium option for controlled suspension tuning on the listed TAMIYA 4WD kits; always validate fitment and wheel alignment after fitting.
