Kyosho Mini Inferno ST / Mini Inferno 09 Alloy Rear Upper Arm Bulk - Front Gearbox Support - MIF012A by GPM  [MIF012A]

Alloy rear upper arm bulk overview

This aluminium rear upper arm bulk is a direct aftermarket replacement designed for Kyosho Mini Inferno ST and Mini Inferno 09 chassis layouts. It fits at the front gearbox junction and pairs with the rear upper arm mounting points, supplied as a single alloy unit with the necessary screws to swap in for the factory plastic part.

The component secures the upper arm pivot area around the front gearbox and provides a stiffer mounting interface that limits unwanted flex. Swapping the stock plastic bulk for this alloy unit can lead to more consistent toe and camber response when cornering or braking, helping drivers dial in predictable handling.

Installation is intended for hobbyists familiar with Mini Inferno teardown. Remove the original front gearbox upper arm retainers, transfer any wheel-side links or bearings as needed, fit the alloy bulk using the supplied hardware, then verify suspension travel and alignment before final tightening to ensure no binding on the drives or steering components.
