Technical Performance
This 43T main differential gear represents ARRMA's engineering excellence in drivetrain components. The straight-tooth design is engineered for optimal mesh geometry, ensuring minimal backlash and maximum power transmission efficiency. Steel construction provides superior hardness and wear resistance compared to inferior materials, critical for maintaining gear tooth integrity under the extreme acceleration forces of brushless 6S LiPo powered RC vehicles. The precision manufacturing process used by ARRMA ensures that every tooth profile matches specification exactly, preventing premature wear and maintaining smooth operation throughout extended driving sessions. This differential gear is specifically calibrated for ARRMA's 6S brushless systems, which operate at high power outputs and demand robust drivetrain components. The 43-tooth ratio has been selected to provide the ideal balance between acceleration response and top speed capability, making this gear suitable for various driving scenarios from competitive circuit racing to high-speed bashing. Regular maintenance and occasional replacement of differential gears is considered best practice among dedicated RC car enthusiasts, as these components experience continuous rotational stress. By keeping a genuine ARRMA 43T spare gear in your RC tool box, you ensure that when replacement becomes necessary, you're installing an OEM-specification component that will perform exactly as your vehicle's designers intended.

Frequently Asked Questions
- Which ARRMA models is the 43T main differential gear compatible with? — This 43T straight gear is compatible with the ARRMA Infraction 6S BLX (available in Blue and Silver variants), ARRMA Typhon 6S V5 BLX, and ARRMA 1/8 TLR Tuned Typhon 6S 4WD BLX Buggy. Always verify your specific model before ordering to ensure correct fitment.
- Why would I need to replace my differential gear? — Differential gears experience continuous rotational stress during driving and can wear over time, particularly under heavy use, high-speed racing, or when bashing over rough terrain. Signs of wear include slipping sensation during acceleration, grinding noises from the drivetrain, or reduced handling predictability. Keeping a spare 43T gear in your RC tool box means you can quickly swap in a fresh component and get back to driving without extended downtime.
- Is this a genuine ARRMA part? — Yes, the Z-AR310441 is an official ARRMA original equipment manufacturer (OEM) part, ensuring authentic quality, precise fitment, and performance that matches your vehicle's design specifications. Always purchase genuine spare parts from authorised retailers to guarantee compatibility and reliability.
- What makes the 43-tooth configuration special? — The 43-tooth straight gear is specifically engineered for ARRMA's 6S brushless platforms, providing the optimal balance between torque delivery, acceleration response, and durability. This tooth count has been selected through extensive testing to perform reliably across various driving conditions and skill levels.
- Can I use this gear in other RC brands? — No, this ARRMA-specific differential gear is designed exclusively for ARRMA models with compatible differential housings. Attempting to use it in other brands or incompatible ARRMA models may result in poor fitment, unreliable performance, or drivetrain damage. Always verify compatibility before installation.
- How often should I replace my differential gear? — The service life of a differential gear depends on driving frequency, terrain, driving style, and maintenance. Casual drivers might replace their gear annually or less frequently, whilst competitive racers using their vehicles multiple times per week might need replacements every few months. Inspect your differential gear regularly for visible wear, pitting, or tooth damage, and replace as needed to maintain optimal drivetrain performance.
- What tools do I need to install this gear? — Installation typically requires basic RC tools including Allen keys (hex wrenches) and a quality screwdriver set. Consult your ARRMA vehicle's manual for specific installation procedures and torque specifications. If you're unfamiliar with differential disassembly, consider having a professional RC technician perform the installation to avoid damage to other drivetrain components.
