Key Features

• Complete Drive Gear Set — This package includes everything you need to replace or upgrade the entire drivetrain: two differential ring gears rated at 37 teeth each, two differential pinion gears rated at 15 teeth each, plus spur gears available in 58-tooth and 70-tooth options (0.5 mod). Having all components ensures perfect compatibility and smooth meshing throughout the drivetrain.
• 58-Tooth Spur Gear Option — The AS21527 spur gear features 58 teeth in 0.5 mod specification, providing a specific gear ratio that's ideal for certain track conditions and driving styles. This tooth count is perfect for refreshing a worn spur gear or returning to your baseline setup when experimenting with different pinion sizes.
• 70-Tooth Spur Gear Alternative — The set also includes a 70-tooth 0.5 mod spur gear option, allowing you to adjust your overall gear ratio and tailor acceleration, top speed and torque delivery to suit your specific driving conditions, whether that's tight technical tracks or more open circuit racing.
• Smooth Power Transfer — These precision-engineered gears support smooth, consistent power delivery from the motor through the drivetrain to the wheels, which is essential for maintaining traction, control and predictable handling throughout your RC buggy's performance envelope.
• Quiet, Efficient Operation — Proper gear mesh and quality gears significantly reduce drivetrain noise and mechanical losses, meaning your RC car runs quieter and more efficiently, with better battery runtime and less strain on the motor and ESC.
• Differential Ring and Pinion Design — The included differential gears (37-tooth rings and 15-tooth pinions) are precisely manufactured to ensure proper torque distribution between the left and right wheels during cornering, maintaining consistent handling characteristics and predictable turning response.
• Genuine Associated Quality — As genuine OEM parts from Associated, these gears are manufactured to the exact specifications of your Reflex 14 platform, ensuring perfect fit, compatibility and long-term reliability that aftermarket alternatives simply cannot match.
• 0.5 Mod Specification — The 0.5 mod (modulus) tooth profile is the standard specification for the Reflex 14 platform, ensuring these gears mesh perfectly with your existing drivetrain components and deliver optimal performance without binding or excessive play.

Technical Performance

The AS21527 gear set represents precision engineering at its finest, delivering the reliability and performance consistency that competitive RC racers demand. The differential ring and pinion gears (37-tooth rings and 15-tooth pinions) work together to distribute power evenly between your buggy's wheels whilst allowing slight speed differences during cornering, which is crucial for maintaining grip and control through fast direction changes. The spur gears (available in both 58-tooth and 70-tooth configurations) directly interface with your pinion gear mounted on the motor shaft, and the tooth count you choose dramatically affects your RC car's acceleration curve and top speed potential. The 58-tooth option provides a balanced setup suitable for mixed terrain and varied driving styles, whilst the 70-tooth spur offers increased torque multiplication for better acceleration from a standstill and improved low-speed control, though at the cost of slightly reduced top speed. These gears are manufactured from high-quality materials and precision-cut to 0.5 mod specification, ensuring consistent mesh with minimal backlash and maximum efficiency. Proper installation and correct gear mesh adjustment (as detailed in your vehicle manual) will ensure these gears deliver thousands of miles of reliable service. The engineering quality behind these gears means less drivetrain noise, smoother power delivery, reduced strain on your motor and ESC, and ultimately better overall performance from your Reflex 14 platform whether you're running a Reflex 14B, 14T, 14R, 14R Hoonitruck, 14MT Monster Truck, or 14B Ongaro variant.

Frequently Asked Questions

• What's the difference between the 58-tooth and 70-tooth spur gears included in this set? — The spur gear tooth count directly affects your buggy's gear ratio and performance characteristics. The 58-tooth spur gear provides a balanced setup with moderate acceleration and decent top speed, making it ideal for mixed track conditions and general driving. The 70-tooth spur gear increases torque multiplication, giving you snappier acceleration and better low-speed control, but reduces top speed slightly — this configuration is often preferred on technical tracks with lots of corners and slow-speed sections. You can experiment with both to find which ratio suits your driving style and track layout best.
• Why should I replace my existing gears with the AS21527 set? — Over time, RC gears wear down through normal use, causing increased backlash, noise, and loss of efficiency. Worn gears can also cause uneven power distribution and inconsistent handling. Replacing your entire drive gear set with this genuine Associated kit restores smooth power delivery, reduces drivetrain noise, improves battery runtime, and ensures your Reflex 14 platform performs as it did when new. Additionally, if you're experimenting with different pinion sizes, having fresh gears ensures you're testing with a known baseline rather than worn components that could skew your results.
• How difficult is it to install these gears in my Reflex 14? — Gear installation requires access to your RC buggy's drivetrain, which typically means removing the transmission cover and differential. The process is moderately technical but well within the capabilities of anyone with basic mechanical knowledge and proper tools. Associated provides detailed installation steps and correct gear mesh adjustment procedures in your vehicle's manual — it's essential to follow these instructions carefully to ensure proper meshing and optimal performance. If you're unsure about the process, RC Model Shop's team of experienced enthusiasts are happy to provide guidance or assistance.
• Are these genuine Associated parts? — Yes, the AS21527 is a genuine OEM (Original Equipment Manufacturer) part from Associated, not an aftermarket substitute. This means it's manufactured to exact Associated specifications, ensuring perfect compatibility, superior quality, and reliable long-term performance. Genuine parts also come with the assurance of proper engineering and quality control that you simply won't get from cheaper alternatives.
• What maintenance do these gears require? — RC gears require proper lubrication to run smoothly and last a long time. Apply a light coat of quality RC gear grease during installation, and periodically check that the gears maintain adequate lubrication during use. Avoid over-greasing, which can attract dirt and debris. Also ensure proper gear mesh adjustment — too tight and the gears wear rapidly, too loose and you'll get excessive noise and backlash. Check your manual for the correct mesh specification.
• Can I use the AS21527 gears on Reflex models other than the 14B and 14T? — Yes, these gears are compatible with the entire Reflex 14 family including the 14R, 14R Hoonitruck, 14MT Monster Truck, 14B Ongaro, and 14B Buggy. If you own any variant of the Reflex 14 platform, this gear set will fit perfectly.
