Platform upgrade kit
Horizon describes this as an all-metal front/rear differential upgrade for ARRMA BOOST, MEGA, or 3S bashers.
Note: Platform-level compatibility statement; model-specific Granite confirmation should be added from ARRMA's upgrade chart before exact-model surfacing.
Possible fit — needs verification
The source only makes a platform-level claim. ExactMods has not confirmed this for the Granite 3S. Do not treat this as a compatible part.
