The Arrowmax AM-010070 BB DJC serves as an RC-scale spare or upgrade part intended for XRAY T4 cars that specify a 52mm BB DJC. The copy stays factual about fit and its use in tuning and maintenance rather than making performance claims.
This item is made to interface with existing T4 assemblies where the 52mm BB DJC dimension is required. Consider it a replacement bearing-related component for scheduled service or targeted setup changes, not a catch-all solution for other platforms.
Installation guidance: verify the 52mm measurement against your T4 wheelbase and mounting layout, inspect mating faces for damage, and fit manufacturer-specified screws if replacements are needed. This description does not include detailed installation steps or imply extra parts are supplied.
Keep the AM-010070 on hand as a spare for XRAY T4 setups that need a 52mm BB DJC, and inspect bearing seats when installing to preserve predictable chassis behaviour.
