Frequently Asked Questions

  • What models does the Losi 17mm hex adapter hardware fit? — This hex adapter hardware is specifically designed for Losi LST, LST2, Muggy and XXL/2 chassis models. If you own any of these Losi platforms, this is the correct hex adapter specification for your vehicle's drivetrain system.
  • Why do I need to replace hex adapter hardware on my RC car? — Hex adapter hardware experiences constant mechanical stress during RC car operation, particularly during off-road bashing, high-speed runs, and competitive racing. Over time, the hex fitting can wear, become stripped, or become damaged, causing sloppy drivetrain connection and potential power loss. Replacing worn hex adapters is essential maintenance that keeps your RC car performing at its best.
  • Is this a genuine Losi part? — Yes, this is genuine Losi manufacture, identified by the Losi part number Z-LOSB3517. Authentic Losi spares ensure exact fitment, proper tolerances, and reliability. Using genuine parts protects your investment in your RC car and prevents compatibility issues.
  • What is the difference between a 17mm hex and other hex sizes? — Hex adapters come in various sizes, with 17mm being the standard for Losi LST, LST2, and Muggy models. Using the correct hex size is critical because an incorrect size will either not fit properly or create a loose connection that compromises drivetrain performance and can cause damage to the motor shaft or drive shafts.
  • How often should I replace my hex adapter hardware? — The frequency of replacement depends on how intensively you use your RC car. Serious bashers and racers may replace hex adapters every few months, whilst casual users might only need replacement once per year. Inspect your drivetrain regularly; if you notice any movement or sloppiness in the hex connection, replacement is recommended immediately.
