Kyosho Mini Inferno Rear Arm Bulk 1 Degree MIF009R/A by GPM  [MIF009R/A]

Aluminium rear arm bulk for Mini Inferno tuning

This aftermarket alloy rear arm bulk is built to fit Kyosho Mini Inferno ST and Mini Inferno 09 models, supplied as a 1pc set with the mounting screws included. The part replaces the stock rear arm bulk to give a tougher aluminium option that helps during routine chassis maintenance and small geometry tweaks.

Compatibility is limited to Kyosho Mini Inferno ST and Mini Inferno 09 as listed in the product name, so double check your chassis before ordering. The item is described as alloy construction with a 1 degree orientation and is intended where small rear geometry changes are needed for setup or repairs.

Installation tips: remove the rear gearbox cover and the existing arm bulk, install the alloy unit in the same orientation as the original and secure with the supplied screws. Use the correct hex driver and apply moderate torque to avoid damaging gearbox threads. After installation, check wheel alignment and suspension travel before running.

Tuning notes: the 1 degree angle gives a minor, consistent change to rear geometry that can assist with handling balance and suspension response on track or at club days. Make incremental changes and log results to dial in your preferred setup.
