MX088/PIN is a CNC-ready replacement front crash pin sized for LOSI PROMOTO-MX mounting points and manufactured to a medium carbon steel specification with a hardened black finish. The material choice balances yield strength and toughness for repeated impact events without excessive brittleness.
The component replaces the stock crash fixing point and is supplied with one Grade 12.9 black round head screw 4x12 to ensure proper clamping force. Installation uses standard hex tooling and requires checking alignment and thread engagement to factory mounting points prior to dynamic testing.
Service guidance: inspect the pin and fastener for plastic deformation or thread damage after significant impacts, re-torque to specified preload after initial runs, and apply an appropriate thread-lock compound for sustained vibration environments. This is an aftermarket upgrade designed to enhance front-end crash durability while preserving correct geometry.
