This aluminium rear gearbox housing is designed for Kyosho Mini-Z Overland kits and is supplied as a 1pcs set with the necessary mounting screws for installation.
As a replacement or hop-up, the alloy housing provides a more rigid enclosure for the rear spur and pinion assembly, aiding alignment under tighter tuning setups. The product includes only the housing and screws; internal gears and bearings should be reused from the original gearbox where applicable.
Installation guidance: remove the stock rear gearbox per Mini-Z service instructions, relocate any bearings or internals into the new housing, then fasten the unit with the supplied screws using the correct hex driver. Familiarity with Mini-Z servicing ensures correct mesh and shaft positioning.
Use this housing when replacing a damaged rear gearbox or when upgrading to a stiffer aftermarket enclosure for Mini-Z Overland drivetrain maintenance; confirm component fit before final tightening.
