This replacement pair is intended for use with Kyosho Mini Inferno chassis that accept the Half8-style rear shaft. The titanium-colour surface is cosmetic for easier inspection and does not imply a specific alloy, while the shafts align with the stock rear swing mount points on compatible models.
Tuning role: the shaft acts as the rotational pivot for rear linkages, keeping axle alignment and bearing preload consistent through corners and on landings. Replacing worn shafts reduces slop that can compromise handling and traction.
Installation advice: supplied as one pair, these fit into the stock rear swing assemblies using the original bearings and fasteners. Remove the rear hub, extract the old shaft, insert the new shaft through the swing arm and reassemble with factory hardware. Confirm smooth movement and check axial play before running.
Care and upkeep: inspect the shafts for wear and scoring when you rebuild, keep mating surfaces clean, and change both sides if one shows visible wear to preserve rear geometry. The titanium-colour finish helps highlight early surface damage.
