This Arrowmax AM-MTX-T2128 front upright disc is an RC-scale spare supplied as a pair (2 pcs) intended for Mugen MTX chassis maintenance and setup work. It serves as the upright/steering disc replacement on the front suspension assembly, helping restore geometry after wear or enabling quick swaps during setup changes.
Compatibility is limited to Mugen MTX-series platforms as noted by the product references; confirm fit against your MTX or MTX-5 front hub assembly before installation. The part is supplied as two identical discs and is intended for hobby-grade model cars only.
Installation notes: remove the wheel hub and steering link as required, inspect wheel bearings and kingpin area for play, then fit the disc onto the upright carrier following your chassis disassembly steps. Check steering throw and camber after reassembly and secure fasteners to factory torque guidelines.
