Overview

The ARRMA Differential Outdrive Z-ARA311187 is an essential spare part for RC enthusiasts who demand reliability and durability during intense off-road action. Whether you're a dedicated basher, competitive racer, or simply someone who enjoys pushing your RC monster truck to its limits, these precision-engineered steel diff outdrives are indispensable components to keep in your RC tool box. Designed specifically for ARRMA's range of high-performance 1/8 scale vehicles, these outdrives are manufactured to exacting standards to ensure consistent performance and longevity, even when subjected to the extreme forces generated during high-speed runs and challenging terrain.

As an authorised ARRMA retailer, RC Model Shop stocks genuine differential outdrives that are compatible with a wide range of ARRMA's most popular models, including the legendary KRATON 6S and NOTORIOUS 6S series. These are the same quality components used in original ARRMA vehicles, engineered to maintain the performance characteristics your RC car was designed for. If you've experienced wear on your existing diff outdrives or simply want to have spares on hand for your next event, the Z-ARA311187 delivers the quality and reliability that discerning RC enthusiasts expect when purchasing genuine ARRMA parts in the UK.

The pack includes two steel diff outdrives, providing excellent value for money and ensuring you have backup components ready for immediate installation should you need them. Keeping quality spare parts readily available is a hallmark of responsible RC ownership, allowing you to maintain peak performance and minimise downtime between runs.

Key Features

• Tough Steel Construction — These diff outdrives are manufactured from high-quality steel that has been specifically chosen for its superior strength and durability, allowing it to withstand the tremendous forces generated during extreme RC action without bending, warping, or failing prematurely.
• Precision Manufactured Slots — Each outdrive features precisely engineered slots that are manufactured to exact tolerances, ensuring a perfect fit with your drive shaft and delivering consistent engagement and power transmission with absolutely no wobble or play.
• OEM ARRMA Specification — These are genuine ARRMA components manufactured to the same specifications as the outdrives originally fitted to your vehicle, guaranteeing compatibility and maintaining the performance characteristics your RC truck was engineered for.
• Long-Lasting Durability — The combination of tough steel material and precision manufacturing creates outdrives that can handle repeated impacts, extreme loads, and challenging driving conditions without degradation, providing years of reliable service.
• Dual Pack Value — With two outdrives included in each pack, you gain excellent value and always have a spare ready for immediate replacement should wear occur.

Technical Performance

The ARRMA Differential Outdrive Z-ARA311187 represents the pinnacle of drivetrain engineering for high-performance 1/8 scale RC vehicles. Manufactured from premium-grade steel, these components are engineered to deliver consistent torque transfer from your differential to your drive shafts whilst maintaining absolute precision during the most demanding driving conditions. The precision-manufactured slots have been meticulously engineered to tolerances that ensure a perfect mechanical fit, eliminating any lateral movement or slippage that could compromise power delivery or create unwanted vibration. This level of manufacturing precision is critical in high-performance RC applications where even minute variations in component fit can accumulate to create noticeable handling degradation. The steel material composition has been specifically selected to provide the optimal balance between hardness and toughness, resisting both fatigue failure from repeated loading cycles and impact damage from sudden shock loads. These outdrives are built to withstand the extreme forces generated by high-powered brushless motors driving through 4WD systems on vehicles like the KRATON 6S and NOTORIOUS 6S, where power delivery can exceed 2000 watts and acceleration creates g-forces that test every component in the drivetrain.

Frequently Asked Questions

• Why should I carry spare differential outdrives in my RC tool box? — Differential outdrives are critical drivetrain components that transmit power from your differential to your drive shafts. During intense RC action, especially on rough terrain or at high speeds, these components can experience wear or suffer impact damage. By carrying spare outdrives, you ensure you can make immediate repairs without interrupting your driving session, allowing you to maximise your track time or bashing time.
• How often will I need to replace my differential outdrives? — The lifespan of differential outdrives depends on your driving style and conditions. Aggressive bashing, high-speed impacts, and rough terrain will accelerate wear compared to casual driving. The steel construction of the Z-ARA311187 is designed for durability, but having spares on hand ensures you're never left with a non-functional vehicle.
• Are these genuine ARRMA parts? — Yes, the Z-ARA311187 are genuine OEM ARRMA components manufactured to exact specifications. When you purchase from RC Model Shop, you're receiving authentic ARRMA parts with full compatibility guarantee, not cheap imitations that may not fit correctly or perform reliably.
• Will these outdrives fit my KRATON or NOTORIOUS truck? — The Z-ARA311187 is specifically engineered for ARRMA 1/8 scale models including the KRATON 6S series and NOTORIOUS 6S series listed in the compatibility section. Before purchasing, please verify your vehicle model matches one of the listed compatible vehicles to ensure proper fitment.
• What tools do I need to install these differential outdrives? — Installation requires basic RC tools including hex keys and a screwdriver set. Your ARRMA vehicle's manual will contain detailed installation instructions. If you're unfamiliar with drivetrain maintenance, our team at RC Model Shop can provide guidance.
• Can I use these outdrives with aftermarket differentials? — The Z-ARA311187 are designed for ARRMA's OEM differential system. If you've upgraded to an aftermarket differential, compatibility may vary. Contact our team for advice on component compatibility with your specific setup.
