Technical Performance
The ARRMA 26T Mod1 Safe-D5 Pinion Gear is engineered for maximum reliability and performance in demanding RC applications. Manufactured from hardened steel, this component delivers exceptional durability even under the extreme stresses of brushless motor operation. The Mod1 pitch specification ensures perfect compatibility with ARRMA's matching spur gears, providing smooth, quiet mesh characteristics that translate directly into efficient power transfer from your motor to the wheels. The Safe-D5 bore utilises a keyed design that prevents slippage and micro-rotation, a critical factor when running high-torque brushless motors where even tiny amounts of play can accumulate into driveline damage or performance loss. This 26-tooth configuration works in conjunction with your spur gear ratio to determine your vehicle's overall gearing, making it an essential tuning component for optimising acceleration, top speed and torque characteristics to match your specific driving style and terrain conditions. Whether you're bashing through loose gravel, climbing steep inclines or powering through mud, this pinion gear delivers the engagement and reliability that serious RC enthusiasts depend on.

Frequently Asked Questions
- What vehicles is this pinion gear compatible with? — The ARRMA 26T Mod1 Safe-D5 Pinion Gear Z-ARA311056 is compatible with the ARRMA 1/5 Kraton 4X4 8S BLX EXB Brushless Monster Truck RTR. Always verify compatibility with your specific RC model before purchasing to ensure proper fit and performance.
- Why would I need to replace my pinion gear? — Pinion gears wear over time with regular use, especially in demanding bashers and competitive racing applications. Worn gears can cause noise, slipping, and reduced power transfer efficiency. Replacing your pinion gear with an original ARRMA component ensures your RC car performs like new and prevents damage to the spur gear and motor shaft.
- What does the 26T tooth count mean? — The 26-tooth count indicates the number of teeth on the gear. A higher tooth count on the pinion gear (paired with your spur gear) creates more aggressive acceleration and torque at the expense of top speed, making it ideal for bashers and terrain drivers who prioritise climbing ability and quick launches over maximum velocity.
- What is the difference between Mod1 and other gear specifications? — Mod1 refers to the modulus or pitch of the gear teeth. Mod1 gears are designed to mesh precisely with other Mod1 gears from ARRMA. Using the correct specification is critical for smooth operation, noise reduction and long component life. Using incorrect gear pitches will cause poor mesh, noise and accelerated wear.
- How do I know if this is the right pinion gear for my setup? — Check your ARRMA vehicle's documentation or parts manual to identify the correct pinion and spur gear ratio for your model. The Safe-D5 bore confirms compatibility with ARRMA's motor systems, but always verify the tooth count matches your vehicle's specifications before installation.
- Is this suitable for beginners? — Yes, this is a straightforward replacement component suitable for any RC enthusiast. Pinion gear replacement requires only basic mechanical knowledge, a small spanner or Allen key, and a few minutes of your time. It's an excellent DIY maintenance task for beginners learning about RC car servicing and maintenance.
