Customer Questions & Answers

  • Question: What is the purpose of the Harden Steel 47T Spur Main Gear in my HPI Savage 4.6?

    Answer: The Harden Steel 47T Spur Main Gear plays a crucial role in transferring power from the engine to the wheels, ensuring smooth acceleration and control. This gear's durable construction enhances the vehicle's performance, making it ideal for high-torque scenarios often experienced in off-road conditions. If you are engaged in racing or off-road adventures, upgrading to this gear can significantly improve your truck’s response and speed.
  • Question: How does the Harden Steel construction benefit the spur gear?

    Answer: The Harden Steel construction provides exceptional strength and resistance to wear, which is vital for maintaining performance during intense use. This material can withstand the stress and strain from various terrains, prolonging the life of your gear. When racing or using your HPI Savage in competitive environments, having a reliable gear ensures that you can focus on performance without concern for mechanical failures.
  • Question: Is this spur gear compatible with other models of the HPI Savage series?

    Answer: Yes, the Harden Steel 47T Spur Main Gear is specifically designed for the HPI Savage 4.6, 21, and 25 SS models, allowing for easy replacement of the original gear. However, always check your vehicle's specifications to confirm compatibility to avoid any issues during installation. This ensures your vehicle consistently delivers optimal performance.
  • Question: How do I install the Harden Steel Spur Main Gear?

    Answer: Installing the Harden Steel Spur Main Gear involves removing the vehicle's differential and replacing the old gear with the new one. Make sure to align it properly to ensure smooth operation. Taking care during the installation process is key, as improper alignment can lead to gear slippage or mechanical issues. If you're troubleshooting performance, this installation can greatly enhance efficiency and reliability.
  • Question: What makes the 47T design preferable for my HPI Savage?

    Answer: The 47T design offers a balance between speed and torque, making it suitable for various driving conditions. A higher tooth count can improve acceleration but may reduce overall speed, while a lower count offers quick response but less climbing ability. For a versatile setup, the 47T is an optimal choice, especially when you want to tackle different terrains effectively.
  • Question: Can I use the Harden Steel spur gear for racing purposes?

    Answer: Absolutely! The Harden Steel 47T Spur Main Gear is designed to handle the rigors of racing, providing enhanced durability and performance that high-speed conditions demand. Its strength reduces the likelihood of failure during races, allowing for consistent performance. Whether you're in a competitive race or just trying to beat your personal best, this gear can give you the edge you need.
  • Question: What tools do I need to replace the spur gear?

    Answer: To replace the spur gear, you will need a set of hex wrenches, a Phillips screwdriver, and possibly a small pair of pliers or a wrench for securing fasteners. Gathering these tools beforehand will streamline the installation process. Having the right equipment can make the difference between a frustrating replacement and a smooth upgrade.
  • Question: How can I maintain the spur gear for longevity?

    Answer: To maintain your Harden Steel Spur Main Gear, regularly inspect it for signs of wear or damage, keep it clean from dirt and debris, and ensure it's appropriately lubricated. Regular maintenance can significantly extend the gear's lifespan and prevent unnecessary breakdowns. Proper care is especially important when frequently using the vehicle in tough conditions.
  • Question: Will upgrading to this spur gear improve my vehicle's performance?

    Answer: Yes, upgrading to the Harden Steel 47T Spur Main Gear can greatly enhance your vehicle's performance. Improved durability translates to better handling and acceleration, particularly in demanding situations like off-road driving or competitive racing. Enhancements in power transfer will result in a more responsive driving experience, allowing for quicker adjustments in tight spots.
