Key Features

• 48-Tooth Steel Construction — This spur gear features a robust 48-tooth count manufactured from hardened steel, providing excellent durability and resistance to wear during intense driving sessions.

Frequently Asked Questions

• What is a spur gear and why does my RC buggy need one? — A spur gear is the large gear that meshes with the pinion gear (mounted on the motor) to transfer power from the engine or motor to your vehicle's drivetrain and wheels. Without a functioning spur gear, your RC car won't be able to accelerate or move. Over time, spur gears can wear out, crack, or chip due to the constant stress of power transmission. The HoBao Hyper 7/VS 48T Steel Spur Gear is a replacement component that restores your vehicle's drivetrain functionality when the original gear is damaged or worn.
• Which HoBao models are compatible with the H87338 spur gear? — This spur gear is compatible with a wide range of HoBao vehicles including the Hyper Cage Buggy RTR with Mach 28 engine (orange and black versions), the Hyper Cage Buggy Electric Roller, the Hyper SS 1/8 RTR Buggy with both Mach 28 6-port and Hyper 21 3-port engines, the Hyper SS 1/8th Buggy Electric Roller, the Hyper SSe 1/8 RTR Buggy with 100A brushless system (both blue and black), the Hyper SS Nitro RTR Off-Road Truggy, the Hyper SS Brushless 1/8th Truggy with 150A 6S brushless, the Hyper SSTe Truggy 1/8th Scale Electric Rolling Chassis, and the Hyper SS Cage RTR Nitro Powered Truggy. If you own any of these models and need a replacement spur gear, the H87338 is the genuine HoBao part you need.
• Is this a steel or plastic spur gear? — The HoBao Hyper 7/VS 48T Spur Gear is manufactured from hardened steel, which offers superior durability compared to plastic alternatives. Steel gears resist stripping, wear, and chipping far better than plastic, meaning you'll get longer service life from this component even with regular use or competitive driving. For serious RC enthusiasts in the UK who want their buggies and truggies to perform reliably, the steel construction makes this an excellent choice.
• What do I need to do to install this spur gear on my RC model? — Installation is straightforward. You'll need to remove the old or damaged spur gear from your differential, then slide the new H87338 into place and secure it properly. The exact installation procedure depends on your specific HoBao model, so consulting your vehicle's manual for differential and drivetrain removal instructions is recommended. Most installations can be completed in under 30 minutes with basic hand tools. The spur gear must be properly meshed with your pinion gear—consult your manual for correct mesh settings to ensure optimal performance and prevent premature wear.
• How often should I replace my spur gear? — The frequency of spur gear replacement depends on how much you drive your RC model and how hard you push it. Regular maintenance and inspection will alert you to wear patterns—excessive noise, grinding sounds, or visible damage to the gear teeth indicates replacement is needed. For casual weekend drivers, a steel spur gear might last many months or even a year or more. For competitive racers or those who bash regularly, replacing the spur gear every few months is reasonable depending on driving intensity. Keeping a spare on hand, as with this H87338, ensures you're never left without an RC vehicle to drive.
• Is the H87338 a genuine HoBao part? — Yes, the HoBao Hyper 7/VS 48T Steel Spur Gear H87338 is a genuine OEM (original equipment manufacturer) part produced by HoBao. The part number H87338 is the official HoBao designation for this component. Purchasing genuine parts ensures perfect compatibility with your vehicle and guarantees the quality and durability standards set by the manufacturer. RC Model Shop stocks only authentic HoBao spares, so you can be confident you're receiving a genuine component.
• Can I use this spur gear on electric and nitro RC vehicles? — Yes, the H87338 is compatible with both electric and nitro-powered HoBao vehicles. Whether you're running a brushless electric system or a nitro engine, this spur gear is engineered to handle the power transmission requirements of both drivetrain types. This versatility is one reason why stocking this part makes sense if you have multiple HoBao models in your collection.
• What is the tooth count and why does it matter? — This spur gear features 48 teeth. The tooth count on a spur gear, combined with the tooth count on your pinion gear, determines your vehicle's overall gear ratio. A 48-tooth spur gear is a popular standard configuration for HoBao models, providing a balanced ratio that works well for both acceleration and top speed across various driving conditions and surfaces. If you've misplaced your original gear specifications, the H87338 with its 48-tooth count is the correct replacement for most standard HoBao differential setups.
