Description

🏁 Dominate Every Terrain with Cobra Racing’s 12mm Hex Extenders (see compatibility list below)

Take control of your RC car’s stance, balance, and performance with Cobra Racing’s 30mm Aluminum Hex Extenders. These precision-engineered 12mm extenders add a full 30mm of width per side, transforming your vehicle’s handling, cornering, and overall presence on the track or trail.

*(Available in multiple colors and styles, including 12mm extenders and 12mm–17mm conversion kits)


🔧 What This Product Does:

  • Widens track width by 30mm per side (total 60mm overall)

  • Improves stability and reduces body roll

  • Reduces chance of rollovers during high-speed cornering

  • Enhances appearance with a more aggressive stance

  • Compatible with all standard 12mm hex wheels


💥 Why This Upgrade Matters:

Whether you’re bashing, racing, or rock crawling, a wider stance equals more control. These extenders are especially useful for off-road applications and high-speed turns, giving you the confidence to push your RC to the limits without tipping or spinning out.

Made from aircraft-grade aluminum, these extenders are both lightweight and ultra-durable — perfect for repeated abuse on demanding terrains.

      Hello Curtis,

      Thank you for taking the time to leave feedback. We’ve emailed you a YouTube link that shows the installation process — we believe the fitment issue is related to installation, not the product itself. To clarify, these extenders are a direct fit for both the 2WD and 4WD Slash platforms.

      Please don’t hesitate to reach out if you need further assistance — we’re happy to help!

      Best regards,
      CR Support
