Kyosho Mini-Z Monster Golden King Pin by 3Racing MZM-003  [MZM-003]

Mini-Z Monster king pin overview

This is an RC-scale Golden King Pin designed for Kyosho Mini-Z Monster chassis, supplied as a replacement steering pivot part produced by 3Racing with catalogue code MZM-003. It functions as the pivot point in the front suspension steering assembly, intended for routine maintenance or when the original pin shows wear.

Constructed for small-scale models, the part's appearance and finish prioritise wear resistance and smooth movement at the steering joint. In typical use it replaces the factory pin without altering core chassis geometry, and it is intended for hobbyist servicing, setup tweaks, and track-side repairs on Mini-Z Monster cars.

Installation notes: remove the wheel and front suspension arm to access the king pin, inspect related bushings or bearings for wear, fit the replacement pin ensuring correct seating and thread engagement, and verify free steering movement before running. After installation, perform a short functional test at low speed to confirm no binding or excess play.

Tuning role: swapping to a new or fresher king pin addresses play in the steering, helps maintain consistent toe and caster under load, and supports predictable steering feedback during setup changes. Use it as part of a regular maintenance routine when front-end looseness affects handling.
