Overview
The ARRMA Metal Spur Gear 59T Z-ARA311196 is an essential replacement drivetrain component for ARRMA GROM series RC vehicles. Whether you're running a 1/18 GRANITE GROM, 1/16 MOJAVE GROM, or 1/14 TYPHON GROM RC monster truck or buggy, this metal spur gear delivers the durability and performance you need to keep your RC car UK-ready for intense bashing sessions and competitive racing. Designed to be a direct replacement for worn or damaged spur gears, this component is manufactured to the highest ARRMA specifications and is trusted by RC enthusiasts across the United Kingdom.
Spur gears are critical components in the drivetrain of any RC car, transferring power from the motor to the wheels through the transmission system. The 59-tooth configuration of this gear is specifically engineered to work harmoniously with the motor and ESC in your ARRMA GROM vehicle, ensuring smooth acceleration, reliable torque delivery, and consistent performance whether you're driving on carpet, tarmac, dirt, or grass. A worn or damaged spur gear can lead to grinding noises, loss of power delivery efficiency, and potential damage to surrounding drivetrain components, which is why having a quality replacement like this metal spur gear on hand is essential for any serious RC hobbyist in the UK.
This replacement part represents genuine ARRMA engineering and quality control, making it the recommended choice over generic alternatives. The tough metal construction ensures longevity even under extreme driving conditions, whilst the precise 0.5 Modulus tooth profile maintains the optimal gear mesh with your vehicle's pinion gear, guaranteeing efficient power transfer and minimising mechanical losses during acceleration and deceleration cycles.
Key Features
- Tough Metal Construction — Manufactured from hardened metal material, this spur gear is engineered to withstand the extreme stresses and impacts that come with RC car driving, whether you're bashing around your garden, competing in local races, or pushing your RC vehicle to its limits. The metal composition resists wear, deformation, and tooth stripping far better than plastic alternatives, ensuring a much longer service life and better value for money.
- 0.5 Modulus Tooth Profile — The precise 0.5 Mod tooth profile is engineered to work with the corresponding pinion gear in your ARRMA GROM vehicle, creating an optimal gear mesh that ensures efficient power transfer from the motor to the transmission. This precise engineering minimises mechanical losses, reduces friction, and helps your RC car achieve better acceleration response and more consistent performance throughout every drive session.
- 59-Tooth Configuration — The 59-tooth count is specifically calibrated for the GROM series of vehicles, providing the correct gear ratio to optimise the balance between acceleration and top speed. This tooth count has been proven in extensive ARRMA testing to deliver the best performance characteristics for the intended vehicle classes.
- Direct Replacement Part — This is a genuine ARRMA replacement component, meaning it is engineered to fit precisely in your vehicle without modification and will restore your RC car to factory performance standards. Using genuine parts ensures compatibility, reliability, and maintains the integrity of your vehicle's drivetrain system.
- Compatible with Multiple GROM Models — This single replacement part works across the entire ARRMA GROM range, including the 1/18 GRANITE GROM, 1/16 MOJAVE GROM, and 1/14 TYPHON GROM models, making it a versatile spare part to keep in your RC tool box whether you run one or multiple GROM vehicles.
Technical Performance
The ARRMA Metal Spur Gear 59T represents a significant upgrade in durability and performance over plastic alternatives commonly found in budget RC cars. The hardened metal construction provides superior resistance to the extreme forces generated during acceleration, braking, and high-speed cornering manoeuvres. The 0.5 Modulus tooth profile is a precision specification that matters tremendously in RC engineering; this measurement determines the size and spacing of the teeth, and even a slight variation can cause poor meshing with the pinion gear, leading to grinding, slipping, and premature wear. ARRMA has spent considerable engineering effort calibrating the 59-tooth spur gear to deliver optimal power delivery across the entire RPM range of the brushed MEGA 380 motors and brushless 223S BLX motors fitted to GROM vehicles. When properly installed in your 1/18, 1/16, or 1/14 scale RC truck or buggy, this gear works in concert with the vehicle's ESC (electronic speed controller), motor system, and transmission to provide smooth, responsive acceleration without slipping or jerking. The metal material resists the heat generated by continuous driving, maintaining its structural integrity even during extended bashing sessions on hot UK summer days. Users report that replacing a worn spur gear with this genuine ARRMA component often eliminates grinding noises that develop as teeth become rounded and damaged, restoring the near-silent operation of a healthy drivetrain.

Frequently Asked Questions
- Which ARRMA models is this spur gear compatible with? — This genuine ARRMA replacement part is compatible with the complete GROM range of vehicles, including the 1/18 GRANITE GROM MEGA 380 Brushed 4x4 Monster Truck RTR (available in red, blue/red, and green colour options), the 1/16 MOJAVE GROM 223S BLX 4x4 Desert Truck (available with and without battery/charger in teal, black, and white), the 1/16 MOJAVE GROM MEGA 380 Brushed 4x4 Desert Truck RTR (in red and blue colours), the 1/16 ARRMA MOJAVE GROM RTA Race Kit, and the 1/14 TYPHON GROM series including the 223S BLX 4x4 Buggy (in red, blue, and silver) and the MEGA 380 Brushed 4x4 Buggy RTR (in red/white and blue/silver). If you're unsure whether your vehicle is compatible, check your manual or contact the RC Model Shop team for assistance.
- Why should I replace my spur gear? — Over time, the teeth on a spur gear wear down through constant meshing with the pinion gear, especially with intensive bashing. Worn teeth become rounded, which reduces the contact area and causes slipping, loss of power delivery, and characteristic grinding or whining noises. Replacing a worn spur gear restores full power transfer efficiency and eliminates noise. Many users report that a gear replacement also improves acceleration response and feels like a noticeable performance upgrade to their RC car's drivability.
- Is this a genuine ARRMA part? — Yes, the Z-ARA311196 is a genuine ARRMA factory replacement part, manufactured to the same specifications as the spur gear fitted to new GROM vehicles. Choosing genuine ARRMA parts ensures perfect fitment, reliability, and optimal performance. Using genuine parts also protects your warranty and ensures compatibility with other ARRMA components in your vehicle.
- What is the difference between metal and plastic spur gears? — Metal spur gears, like this ARRMA component, offer superior durability and longevity compared to plastic alternatives. Metal resists wear, maintains its tooth profile longer, resists heat deformation, and can handle higher stresses without stripping. Plastic gears are lighter but wear more quickly and are prone to tooth stripping under heavy acceleration or impact. For any serious RC hobbyist in the UK, metal gears represent better value over time due to their extended lifespan.
- How do I know if my spur gear needs replacing? — Common signs include a grinding or whining noise from the drivetrain, loss of acceleration response, visible damage or missing chunks from the teeth, or slipping sensation when accelerating. If you hear any unusual noises when driving your RC car, it's worth inspecting the spur gear. A replacement is typically straightforward and is often a worthwhile maintenance step for high-use vehicles.
- Can I use this part on other ARRMA vehicles? — This spur gear is specifically designed for the GROM range of vehicles and uses the 0.5 Modulus tooth profile and 59-tooth configuration specific to those models. Other ARRMA vehicles may use different tooth counts, modulus values, or mounting systems. Always check your vehicle manual or contact RC Model Shop to confirm compatibility before purchasing.
