Switch Overview

The HMX Sonja HC, or Sonja Hardcore, uses a customized stem and housing for a nostalgic rail bottom-out and a scratchy feel, making it a more OG version of the Sonja. It suits anyone who likes the Sonja but wants something scratchier with a heavier spring. Factory lubing follows the Snow Crash method: only the leaves and springs are lubed, leaves with a thin coat of a 205g0 and 105g0 mix and springs with dry-film, leaving stem and housings dry. Top housing is modified PA66 with added texture.
