Technical Performance
The ARRMA Dogbone 157mm represents a critical drivetrain component in 1/7 scale brushless RC vehicles, where the demands on transmission internals are substantial. When coupled with ARRMA's brushless power systems and high-capacity 6S LiPo batteries, the drivetrain must transfer tremendous torque and power to the wheels reliably and efficiently. This dogbone's strong steel construction provides the rigidity necessary to handle continuous acceleration, cornering forces, and the shock loads that occur during off-road RC driving. The precision-manufactured drive pins are engineered to exacting tolerances, ensuring zero backlash or play between the dogbone and the transmission drive cups. This tight tolerancing is essential for maintaining steering precision and power delivery, particularly important in competitive racing environments or when pushing your RC truck to its performance limits. The 157mm length has been specifically designed to work seamlessly with ARRMA's 1/7 scale transmission geometry, maintaining proper driveshaft alignment and operating angle. Whether you're running your MOJAVE, FIRETEAM, or BIG ROCK on high-grip asphalt, loose sand, or rough rocky terrain, this component is engineered to perform consistently and reliably. The steel material choice provides superior strength compared to plastic alternatives, making this the professional-grade choice for serious RC car enthusiasts who understand that drivetrain reliability directly impacts performance and enjoyment of their vehicles.

Frequently Asked Questions
- What ARRMA models does the 157mm dogbone fit? — This dogbone is compatible with multiple ARRMA 1/7 scale vehicles including the MOJAVE 6S V2, FIRETEAM 6S 4X4, BIG ROCK 6S 4X4, and MOJAVE 6S EXB models. If you own any of these brushless RC trucks or buggies, this is the correct replacement part for your transmission.
- How do I know if I need to replace my dogbone? — Dogbones may require replacement after extended use, if you notice transmission play or clicking sounds during acceleration, or if the component has sustained impact damage. As a wear item in high-performance RC vehicles, having a spare dogbone in your parts box is sensible maintenance practice.
- Is this a genuine ARRMA part? — Yes, this is an authentic ARRMA spare part with the manufacturer part number ARA310952. Buying genuine ARRMA components ensures perfect fitment and the same quality standards as the parts included in new ready to run RC kits.
- Will this work with other RC car brands? — This dogbone is specifically engineered for ARRMA 1/7 scale vehicles and is not compatible with other manufacturers' drivetrain systems. The 157mm length and drive pin specifications are unique to ARRMA's transmission design.
- What is the difference between this and plastic dogbones? — This steel dogbone offers superior strength and durability compared to plastic alternatives, particularly important for high-power brushless vehicles like the 6S-capable MOJAVE and FIRETEAM models. Steel construction resists flexing and deformation under heavy load, maintaining precise drivetrain geometry and performance.
- Is this suitable for beginners? — This is a replacement spare part rather than a beginner product in itself. However, beginners who own ARRMA ready to run RC trucks will benefit from having a spare dogbone available for maintenance and repairs as they develop their RC skills and driving experience.
