ARRMA Spur Gear Mod1 46T: Nero Z-AR310577

Overview

The ARRMA Spur Gear Mod1 46T is a premium replacement drivetrain component designed for RC enthusiasts who demand reliability and consistent performance from their vehicles. Whether you're running an RC car UK or operating a high-performance brushless RC model, this spur gear is engineered to handle the demands of large-scale brushless motors with ease. The 46-tooth configuration strikes an excellent balance for a wide range of driving styles and motor setups, making it an essential spare part for anyone serious about maintaining their RC vehicle in peak condition.

Built to ARRMA's exacting standards, this MOD1 spur gear is a direct replacement for the kit-supplied item (replaces AR310729) and delivers the durability and precision that competitive RC drivers and weekend bashers alike have come to expect. If you've been looking for a high-quality spur gear that won't let you down during intense track sessions or rough terrain driving, this is the spare part you need in your pit box.

Key Features

• Super-Strong Steel Construction — This spur gear is manufactured from premium-grade steel that provides exceptional durability and longevity, ensuring it maintains structural integrity even under the extreme stresses imposed by powerful brushless motors commonly found in modern RC cars and trucks.
• Precision-Manufactured Tooth Configuration — Every tooth is engineered with surgical precision to ensure smooth power transfer throughout the drivetrain, which translates to consistent performance, reduced noise during operation, and minimal wear on meshing pinion gears.
• Optimised for Brushless Motor Power — This component is specifically engineered to work seamlessly with the high torque and RPM outputs of large-scale brushless electric motors, giving you confidence that your drivetrain can handle maximum performance without slipping or stripping teeth.
• MOD1 Tooth Profile — The MOD1 (Module 1) tooth profile is a standard specification in the RC industry, ensuring compatibility with MOD1 pinion gears and providing reliable meshing characteristics for smooth acceleration and deceleration.
• Direct OEM Replacement — As an official ARRMA part, this spur gear serves as a direct replacement for AR310729, meaning fitment is guaranteed and you maintain factory-specification performance characteristics.

Technical Performance

The ARRMA Spur Gear Mod1 46T represents the pinnacle of drivetrain engineering for competitive and recreational RC vehicles across the UK and beyond. With 46 teeth and MOD1 specification, this component is designed to deliver consistent mechanical advantage when paired with appropriately-sized pinion gears and high-performance brushless motors. The precision manufacturing process ensures that tooth engagement is smooth and predictable, eliminating the chattering or gear noise that can occur with lower-quality components. The superior steel composition means the gear resists the kind of wear that can gradually degrade performance, maintaining that fresh-out-of-the-box feel even after extended use. For drivers running brushless RC setups with substantial motor power, this spur gear is the difference between a drivetrain that merely survives and one that thrives through countless hours of intense driving. The engineering has been optimised for both high-acceleration running and sustained high-speed performance, making it equally at home in off-road bashers, on-road racing platforms, or mixed-terrain vehicles.

Frequently Asked Questions

• Is the ARRMA 46T MOD1 spur gear suitable for my brushless RC car or truck? — Yes, this spur gear is specifically engineered to work with large-scale brushless motors and is compatible with any RC vehicle using MOD1 tooth profile components. If your vehicle originally came with an ARRMA drivetrain or accepts MOD1 specifications, this gear will integrate seamlessly into your setup.
• What does MOD1 mean and why is it important? — MOD1 refers to Module 1, which is a standardised tooth profile specification used across the RC industry. This ensures that the spur gear will mesh correctly with MOD1 pinion gears and maintain proper tooth engagement for reliable power transfer and longevity.
• How long will this spur gear last? — The premium steel construction provides excellent durability and resistance to wear, meaning you can expect extended service life compared to lower-grade alternatives. Lifespan depends on driving intensity, but the precision engineering ensures consistent performance throughout its operational life.
• Can I use this with my existing RC setup? — This is a genuine ARRMA part designed as a direct replacement for AR310729. It will work with any ARRMA vehicle that used this component, and it's also compatible with other brands using MOD1 spur gears paired with appropriately-sized MOD1 pinion gears.
• Why would I need to replace my spur gear? — Spur gears can wear over time due to high-speed driving, or teeth may become damaged if the drivetrain experiences sudden mechanical shock. Replacing a worn or damaged spur gear is essential to maintain smooth operation, prevent further drivetrain damage, and restore optimal performance to your RC vehicle.
• What pinion gear sizes work with the 46T MOD1? — The 46T configuration is versatile and works with various MOD1 pinion sizes depending on your desired gear ratio and performance characteristics. Your vehicle documentation or RC retailer can advise on the best pinion-to-spur ratio for your driving style.
