Overview
The ARRMA 30T Mod1 Safe-D5 Pinion Gear (Z-ARA311060) is an essential replacement and upgrade component for RC enthusiasts running ARRMA vehicles in the UK. Whether you're a dedicated basher pushing your RC car to its limits or a competitive racer fine-tuning your setup for maximum performance, pinion gears are critical drivetrain components that directly influence acceleration, top speed and overall vehicle dynamics. This genuine ARRMA pinion gear delivers the precision engineering and reliability you expect from one of the world's leading RC manufacturers, ensuring your RC monster truck or buggy performs at its best every time you hit the track or terrain.
Pinion gears are one of the most frequently replaced parts in any RC car, particularly for those who bash hard or race competitively. The ARRMA 30T Mod1 Safe-D5 Pinion Gear offers a larger tooth count compared to smaller pinion options, making it ideal for setups where you want to prioritise mid-range torque and acceleration over top speed. This makes it a versatile choice for mixed terrain, technical courses and driving conditions where raw power matters more than pure velocity. If you're looking for a reliable, authentic ARRMA pinion gear for your 1/5 scale brushless monster truck or similar ARRMA vehicle, this is the genuine part you need.
Sourcing the correct replacement parts for your RC car is crucial to maintaining performance and longevity. The Safe-D5 bore type ensures compatibility with your existing drivetrain whilst the Mod1 pitch guarantees perfect meshing with your spur gear. Available from RC Model Shop, a trusted UK RC retailer stocking genuine ARRMA components, this pinion gear is ready to ship and in stock for immediate despatch.
Key Features
- 30 Teeth (Mod1) — This pinion gear features 30 teeth using Mod1 pitch, which is the standard module specification for ARRMA drivetrain components. The larger tooth count provides increased torque delivery and acceleration compared to smaller pinion gears, making it perfect for bashers who want responsive, powerful low-end performance rather than maximum top speed.
- Mod1 Pitch Standard — Operating on the Mod1 pitch standard ensures perfect compatibility and smooth meshing with your ARRMA spur gear, reducing wear, noise and drivetrain inefficiency. This specification guarantees the gear will work seamlessly within your existing RC setup without any modifications or compatibility issues.
- Safe-D5 Bore Type — The Safe-D5 bore is ARRMA's proprietary safe drive system bore, designed to provide a secure connection to your motor shaft whilst protecting both the gear and motor from damage during high-impact bashing or racing. This safety-focused design is particularly valuable for aggressive drivers who subject their RC cars to extreme conditions.
- Genuine ARRMA Component — This is an authentic ARRMA part number Z-ARA311060, not an aftermarket substitute. Genuine ARRMA parts ensure the highest standards of precision manufacturing, material quality and performance reliability. Using genuine components protects your investment and maintains the integrity of your RC vehicle.
- Direct Replacement Part — Designed as a direct replacement pinion gear for compatible ARRMA models, installation is straightforward and requires no modifications to your existing drivetrain. Simply remove the old pinion, fit the new one and adjust your mesh accordingly.
Technical Performance
The ARRMA 30T Mod1 Safe-D5 Pinion Gear represents the engineering precision expected from ARRMA's component range. Manufactured to exacting tolerances, this pinion gear delivers consistent performance and longevity whether you're running a 1/5 scale brushless RC monster truck like the ARRMA Kraton 4X4 8S BLX or operating in similarly demanding RC environments. The Mod1 pitch ensures optimal tooth engagement with your spur gear, minimising noise and maximising power transmission efficiency. With 30 teeth, this pinion strikes a balance between acceleration and top speed—whilst smaller pinions like 12T or 13T options prioritise pure velocity, the 30T configuration favours responsive acceleration and mid-range torque, making it ideal for technical driving, tight courses and situations where controlled power delivery matters more than all-out speed. The Safe-D5 bore incorporates ARRMA's proven safety drive technology, which prevents catastrophic gear stripping during aggressive driving or when the motor experiences sudden resistance. For serious RC bashers and competitors running brushless setups in the UK, this pinion gear delivers the performance, durability and reliability that separates genuine ARRMA parts from inferior alternatives.

Frequently Asked Questions
- What vehicles is this ARRMA 30T pinion gear compatible with? — This pinion gear is confirmed compatible with the ARRMA 1/5 Kraton 4X4 8S BLX EXB Brushless Monster Truck RTR and other ARRMA vehicles featuring Mod1 pitch and Safe-D5 bore drivetrain components. Check your vehicle's documentation to confirm compatibility before ordering.
- What is the difference between the 30T and smaller pinion gears like 12T, 13T, 26T and 27T options? — Pinion gear tooth count directly affects the gear ratio and vehicle performance. Smaller teeth (12T, 13T) provide higher top speed but reduced acceleration and more load on the motor. Medium teeth (26T, 27T) offer balanced performance. The 30T configuration prioritises acceleration and torque over maximum speed, making it ideal for bashers who want responsive, powerful performance rather than pure velocity. Your choice depends on your driving style, terrain and desired performance characteristics.
- Why would I need to replace my pinion gear? — Pinion gears wear during normal operation, especially in competitive racing or aggressive bashing. Worn teeth cause drivetrain noise, inefficiency and power loss. Additionally, different pinion tooth counts allow you to adjust your vehicle's performance profile—upgrading to a 30T from a smaller pinion will alter your acceleration and top speed balance. Regular inspection and replacement ensures optimal performance and longevity of your entire drivetrain.
- What does Safe-D5 bore mean? — Safe-D5 is ARRMA's proprietary bore system designed to safely connect your pinion gear to your motor shaft. This safety drive design protects your motor and gear from stripping during extreme bashing, crashes or high-impact scenarios. It's particularly valuable for brushless setups operating at high power levels where drivetrain stress is significant.
- Is this suitable for beginners? — This is a replacement component best suited for users with basic RC maintenance knowledge. Beginners should ensure they understand how to safely remove and install a pinion gear, adjust motor-to-spur mesh correctly and understand gear ratios before ordering. If you're new to RC, we recommend purchasing a complete ready-to-run RC vehicle and consulting guides or speaking with experienced RC enthusiasts before attempting drivetrain modifications.
- Do I need any tools to install this pinion gear? — Installation requires basic RC tools including a pinion gear puller or small hammer for safe removal, a feeler gauge for mesh adjustment and standard hex drivers. Consult your vehicle's manual for detailed installation instructions and mesh specifications to ensure proper fitment.
