This 87-tooth spur gear is specifically designed to work within ARRMA's transmission systems, ensuring perfect compatibility and optimal power delivery to your RC car's wheels. Whether you've damaged your existing spur gear through intense track sessions or are upgrading your RC buggy's drivetrain, this replacement part provides the quality assurance you expect from an authorised ARRMA spare part.

Built to the exacting standards that RC racers and hobbyists have come to expect, this spur gear combines advanced manufacturing techniques with proven materials science to deliver consistent performance lap after lap. RC enthusiasts across the UK trust ARRMA components for their reliability, and this spur gear continues that tradition of excellence.

Key Features

• Precision Manufactured Tooth Configuration — Every tooth is engineered with exact specifications to ensure smooth meshing with your RC car's pinion gear, eliminating binding, slippage, and power loss. This precision directly translates to more responsive acceleration and better overall handling characteristics on the track or trail.
• Custom Moulded Slipper Pad Insert Slots — The integrated slots for slipper pad inserts allow you to fine-tune your RC car's drivetrain characteristics, giving you the ability to adjust slip behaviour during acceleration and cornering. This feature is particularly valuable for competitive RC racing where drivetrain tuning can mean the difference between winning and losing.
• Moulded Tooth Size Specification — The teeth are precisely moulded to ARRMA's exact specifications, ensuring perfect compatibility with ARRMA transmission systems and pinion gears. This attention to detail prevents wear and tear on mating components and extends the service life of your entire drivetrain assembly.
• Super-Durable Material Construction — Manufactured from hard-wearing, heavy-duty polymer material, this spur gear resists the extreme stresses generated during high-speed runs, acceleration events, and aggressive cornering manoeuvres that characterise RC car driving.
• Drop-in Replacement Design — As a genuine ARRMA spare part, this spur gear fits directly into your existing RC car without modification, making gear changes quick and straightforward whether you're at home or at the track.

Technical Performance

The ARRMA Spur Gear 48P 87T represents the cutting edge of RC drivetrain engineering. The 87-tooth configuration combined with the 48-pitch specification defines the gear ratio characteristics of your RC car's transmission, directly affecting acceleration, top speed, and overall drivetrain responsiveness. At 87 teeth, this is a larger spur gear suitable for RC cars that require optimised low-end torque delivery or where track conditions demand controlled acceleration characteristics. The 48-pitch (48P) designation refers to the tooth pitch standard, ensuring precise meshing with compatible pinion gears across ARRMA's product range. The construction from hard-wearing super-durable material means this gear withstands repeated engagement and disengagement cycles, high-load conditions during acceleration, and the continuous friction generated during competitive racing sessions. Whether you're driving an RC buggy through challenging terrain, pushing your RC monster truck to its limits on the track, or enjoying casual weekend bashing sessions, this spur gear delivers consistent, reliable performance. The custom-moulded slipper pad insert slots provide tuning flexibility, allowing experienced RC enthusiasts to optimise drivetrain slip characteristics for their specific driving style and track conditions. This level of engineering detail demonstrates ARRMA's commitment to providing components that satisfy both recreational RC drivers and serious competitors.

Frequently Asked Questions

• What ARRMA RC car models is this spur gear compatible with? — This 48P 87T spur gear is designed as a genuine ARRMA replacement component for vehicles in their product range that use this transmission specification. Check your ARRMA RC car's manual or parts diagram to confirm compatibility with your specific model, as ARRMA manufactures various scales and types of RC vehicles including buggies, trucks, and crawlers.
• When should I replace my RC car's spur gear? — You should consider replacing your spur gear if you notice stripped teeth, uneven wear patterns, difficulty engaging with the pinion gear, or a reduction in acceleration smoothness. Regular inspection after intensive driving sessions helps identify wear early, preventing secondary damage to your pinion gear or transmission housing.
• What is the difference between the 87T and other tooth count options? — Different tooth counts like the alternative AR310021 model change your RC car's gear ratio, affecting acceleration versus top-speed balance. The 87-tooth configuration on this model emphasises low-end torque and acceleration response, making it suitable for drivers who prioritise quick acceleration over maximum speed potential. Higher tooth counts typically favour acceleration, whilst lower tooth counts favour top speed.
• Is this a genuine ARRMA part? — Yes, the Z-AR310019 is an official ARRMA replacement component manufactured to the same specifications and quality standards as the spur gears fitted to new ARRMA RC cars. When you purchase from authorised retailers like RC Model Shop, you receive genuine ARRMA components with full compatibility assurance.
• How long does a spur gear typically last? — Spur gear longevity depends heavily on driving style, track conditions, maintenance practices, and how well your drivetrain is tuned. Aggressive drivers or those who regularly strip out will experience shorter gear life, whilst careful drivers maintaining proper drivetrain mesh and slipper adjustment can extend component life considerably. Regular cleaning and inspection help maximise the service life of your spur gear.
