Kyosho Inferno MP7.5 Gearbox Upper Arm Bulk Aluminium (2deg Caster, +2deg Toe-in) MP7509A by GPM  [MP7509A]

Front bulk description

This replacement upper arm bulk is intended for the Kyosho Inferno MP7.5 front gearbox. The component locates the upper arm pivot and establishes a fixed 2deg caster with a +2deg toe-in, providing a direct-fit match to MP7.5 geometry.

Installation is carried out using the MP7.5 gearbox and upper arm tower mounting points. Use the supplied or stock hex screws with correct engagement, do not over-tighten to avoid damage to surrounding plastic parts, and check wheel alignment after fitting to confirm caster and toe settings are correct.

In setup work the bulk offers a repeatable datum for front suspension geometry when you alter arm length, shock mounting, or roll centre height. Fit it to restore factory geometry or to create a stable baseline for comparative tuning on the MP7.5.
