Kyosho Inferno MP7.5 Alloy Lower Arm Bulk for Front Gearbox (Caster 2deg, Toe-in +2deg) by GPM MP7508RA  [MP7508RA]

Alloy lower arm bulk for Inferno MP7.5

This aftermarket lower arm bulk is produced by GPM for use with the Kyosho Inferno MP7.5 front gearbox assembly. The part is an aluminum lower arm bulk designed to accept a front gearbox layout with a caster angle set to 2 degrees and a toe-in of +2 degrees. It is supplied as a 1pc set and includes the necessary screws for mounting.

Fitment is intended for the MP7.5 platform only, so confirm mounting points match your existing front gearbox and suspension mounts before installation. The part replaces the corresponding stock lower arm bulk on the front gearbox side and uses the same screw locations; no additional drilling or modification is implied in the product description.

In setup terms this component serves a chassis-level role: it locates the lower suspension arm relative to the front gearbox and contributes to repeatable caster and toe settings. Use it when you need a metal replacement for the factory part, for repairs, or when adjusting front-end geometry during tuning sessions.
