Kyosho Inferno MP7.5 Upper Arm Bulk Alloy for Front Gearbox MP7509B by GPM  [MP7509B]

Upper arm bulk in alloy for front gearbox mounting

This alloy upper arm bulk is specified for use with the Kyosho Inferno MP7.5 front gear box as an aftermarket upgrade. It establishes front suspension geometry at caster 2deg and toe-in +5deg as described in the product title. The item is supplied as 1pcs and functions as a direct replacement option for the MP7.5 front gearbox area.

The component performs as both a structural upgrade over the standard plastic bulk and as a fixed-geometry unit that determines the stated caster and toe-in at the front. During installation confirm the gearbox mounting points and retain OEM fasteners where appropriate; the bulk is designed to fit the MP7.5 front gearbox without modifying adjacent chassis parts.

Use the bulk as the foundation for setup and roll centre adjustments; since caster and toe-in are fixed by this piece, tune steering characteristics via link adjustments and toe/camber block choices to achieve the handling balance you need for practice or competition.
