This 73mm rear spring damper is engineered as an aftermarket upgrade for Kyosho Mini Inferno platforms and is supplied as a 1pr set. Constructed from CNC-friendly alloy components, the assembly includes an alloy ball top and the mounting hardware referenced in the product title.
Designed to replace soft or worn plastic shock components, the damper provides a firmer, repeatable mounting point and improved tuning stability. The hardware package contains screws, alloy collars, and 3mm lock nuts to match standard Mini Inferno rear shock mounts.
During installation, confirm the shock length and ball-top geometry match your Mini Inferno ST or Mini Inferno 09 rear towers. Set spring preload and damping consistent with your setup goals, ensure correct thread engagement on 3mm lock nuts, and verify there is no interference at full droop or compression.
