This alloy breaker is an RC-scale replacement part produced by GPM for the TAMIYA Tractor Truck (King Hauler) platform. It is supplied as 1 pcs and described as an alloy component intended for use on scale tractor truck models.
As an aftermarket repair element, the breaker is intended to restore a key chassis junction on King Hauler style trucks and support repeatable alignment during setup. Install to replace failed or fatigued plastic equivalents and regain a stable mounting point for tuning tasks.
Professional fitment advice: align the part to the existing chassis mounting points, confirm even seating and torque fasteners to recommended values, then inspect chassis play and steering geometry during reassembly. The alloy offers a firmer mating surface than typical plastics and is intended to improve consistency of adjustments.
