This broad compatibility makes it a versatile spares part for anyone running multiple HoBao vehicles.
• Direct Replacement Component — This is a straightforward replacement part that requires no modification or adaptation, simply removing the old crown gear and installing the new one. For serious RC car enthusiasts who like to maintain their own vehicles, having genuine replacement components ensures you're not compromising on quality.
• Essential Maintenance Part — Differential gears experience significant wear during regular racing and bashing, particularly when pushing your RC car hard. Having a genuine HoBao replacement crown gear on hand means you can quickly restore your vehicle to peak performance whenever wear becomes apparent.

Technical Performance

The HoBao Hyper Extreme VTE2 1/7 Diff Crown Gear 40T represents precision engineering at its finest, designed for the high-speed, high-stress environment of competitive on-road RC racing. This crown gear is a critical component of the differential system, responsible for transmitting power from the motor to the drive wheels while allowing them to rotate at different speeds during cornering—an essential function for maintaining traction and control. The 40-tooth configuration, designed to work with a 15T pinion gear, creates a carefully calculated gear ratio that HoBao engineers have determined optimal for the VTE2's performance envelope. Built to withstand the rigorous demands of both competitive racing and recreational bashing, this component is manufactured from durable materials selected specifically for their strength and resistance to wear. The precision tooth profile ensures minimal backlash and smooth engagement, eliminating the kind of play that can cause unpredictable handling or loss of traction when cornering hard. For 1/7 scale electric RC cars operating at the speeds the Extreme VTE2 is capable of, having a reliable, well-maintained differential system is absolutely critical to consistent lap times and predictable handling characteristics. Whether you're running this component in a 1/7 Extreme VTE2, the newer VTE2-V2 variant, or even in compatible 1/8 scale HoBao platforms, you can be confident that you're installing a component built to HoBao's demanding specifications.

Frequently Asked Questions

• What is a diff crown gear and why might I need to replace it? — The differential crown gear is a critical component that works with the pinion gear to transmit power from the motor to your RC car's drive wheels whilst allowing them to spin at different speeds during cornering. Over time, these gears experience wear from the constant meshing and stress during racing or bashing. If you notice your RC car losing traction, experiencing strange grinding sounds from the differential, or simply want to maintain your vehicle with fresh components, a replacement crown gear is essential.
• Is this 40T crown gear compatible with my HoBao vehicle? — Yes, this crown gear is specifically designed for the HoBao 1/7 Extreme VTE2 and VTE2-V2 platforms, as well as the 1/8 Extreme VTE2. It also works with various HoBao Hyper GTS and GTB electric on-road models. Always verify your specific model before purchasing, as different HoBao platforms may use different differential configurations.
• What pinion gear does this crown gear pair with? — This 40T crown gear is designed to work with a 15T pinion gear. The combination of these two gears creates the differential ratio that HoBao engineers have optimised for the VTE2 platform's performance characteristics. Using the correct pinion size is essential for proper differential function.
• Do I need any special tools to install this crown gear? — Installation of the crown gear typically requires basic RC maintenance tools including hex drivers and potentially a small press or gear puller, depending on how your specific model is configured. We recommend consulting your HoBao vehicle's manual for detailed installation instructions, or contacting our expert team for guidance if you're unfamiliar with differential maintenance.
• How often should I replace the diff crown gear? — The lifespan of your crown gear depends heavily on how intensively you use your RC car. Competitive racers might replace differential components seasonally, whilst recreational bashers might go several years between replacements. Watch for signs of wear such as increased noise, loss of traction, or visible damage to the gear teeth.
• Is this a genuine HoBao part or a third-party alternative? — This is a genuine HoBao manufacturing component, as specified by the official HoBao part number OP-0146. Genuine HoBao spares ensure perfect fit, function, and longevity—critical factors when maintaining precision RC equipment.
