Overview
The ARRMA Diff Set Front or Rear 43T Spiral (Z-AR220041) is an essential replacement differential assembly designed for serious RC enthusiasts who demand reliability and performance from their 1/10 scale RC cars. Whether you're running the ARRMA MOJAVE 6S V2 BLX or another compatible platform, this high-quality differential set provides the precision engineering and durability needed to keep your RC model performing at its best. As an RC car UK hobbyist, you'll appreciate the professional-grade construction that makes this component ideal for both weekend bashing and competitive racing scenarios.
This front or rear differential set is manufactured with materials and precision tolerances that far exceed standard RC spare parts. The 43T spiral gear configuration offers excellent acceleration and torque characteristics, making it perfect for drivers who want to optimise their RC vehicle's drivetrain performance. If you're serious about maintaining your RC car UK setup in peak condition, this genuine ARRMA differential assembly is a worthwhile investment that will keep your model running smoothly for years to come.
The differential is the critical component that allows your RC car's wheels to rotate at different speeds during cornering, which is essential for proper handling and manoeuvrability. When your existing differential wears out or sustains damage during aggressive driving, replacing it with this authentic ARRMA spare part ensures you maintain the manufacturer's intended performance characteristics. This complete differential set includes everything needed for installation, though it does require careful assembly and the correct differential oil specification.
Key Features
- Super-tough steel Crown Gear — The 43T spiral crown gear is manufactured from premium hardened steel that resists wear and damage even under extreme driving conditions, ensuring consistent performance throughout the life of the component.
- Durable Planetary and Satellite Gears — All internal gears are precision-manufactured from super-tough steel, providing long-lasting durability in all conditions and maintaining smooth power delivery to your wheels without slippage or grinding.
- Super-strong Differential Case — The main differential case is engineered for increased durability under extreme loads, preventing cracking or distortion that could compromise your RC car's performance during hard cornering or acceleration.
- Precision-manufactured Screw Threads — Every screw thread in this assembly has been precision manufactured to ensure fast and easy servicing, allowing you to disassemble and reassemble the differential without stripping threads or struggling with installation.
- Precision Gear Teeth — The gear teeth are manufactured with exacting tolerances to provide consistent performance at high speeds, eliminating the gear noise and vibration that can occur with lower-quality replacements.
- Specially designed Diff Case Insert — This component is specifically engineered to increase strength and durability, preventing the case from flexing or deforming under load and maintaining proper alignment of all internal components.
- Metal Cross Shafts — Rather than plastic alternatives, this set includes genuine metal cross shafts that provide increased efficiency of fit and long-lasting durability, resisting wear from constant rotational forces.
- Complete Assembly Kit — Everything required for a complete differential rebuild is included in this set, eliminating the need to source multiple components from different suppliers and ensuring compatibility between all parts.
Technical Performance
The ARRMA Diff Set Z-AR220041 represents professional-grade engineering specifically designed for high-performance RC applications. The 43T spiral differential configuration is optimised for vehicles in the 1/10 scale category, providing the perfect balance between acceleration response and top-speed capability. The use of hardened steel throughout the gear train ensures minimal wear even under continuous high-speed driving or aggressive bash sessions typical of RC car UK enthusiasts. The differential case features reinforced design elements including the specially engineered case insert that prevents flex and maintains precise gear alignment even under extreme lateral loads experienced during rapid cornering. All precision manufacturing tolerances are held to exacting standards, ensuring that gear teeth maintain consistent contact patterns and tooth engagement throughout the full range of operation. The metal cross shafts and satellite gear assembly work in concert to distribute power evenly to both output shafts whilst allowing the necessary speed differential during turns. This complete rebuild kit is rated for use in both front and rear differential positions, making it an exceptionally versatile spare part that can address wear in either location. The assembly requires suitable differential oil of the correct specification to function properly; using the wrong oil viscosity will compromise performance and potentially cause premature wear.

Frequently Asked Questions
- Is the ARRMA Diff Set Z-AR220041 suitable for beginners? — Whilst this is a genuine ARRMA spare part of excellent quality, differential assembly requires mechanical skill and attention to detail. Beginners may find the process challenging without prior experience, but the precision-manufactured components and included instructions make it achievable for anyone willing to take their time and follow procedures carefully.
- What models does this ARRMA differential fit? — This set is compatible with the ARRMA MOJAVE 6S V2 BLX in both Green/Black (C-ARA7604V2T1) and Red/Black (C-ARA7604V2T2) colour variants. It can be installed in either the front or rear differential position depending on your needs.
- What differential oil specification do I need? — The source documentation requires assembly with suitable differential oil, but you must consult your specific vehicle's manual to determine the correct viscosity grade required for optimal performance.
- Can I use this in both front and rear positions? — Yes, this is a universal front/rear differential set, meaning the same components can be used to rebuild either the front or rear differential assembly depending on which one requires maintenance or replacement.
- Why should I use genuine ARRMA spare parts instead of aftermarket alternatives? — Genuine ARRMA components like this differential set are engineered to the exact specifications of your vehicle, ensuring perfect fitment and performance characteristics. The precision manufacturing and material selection used in ARRMA spares guarantees compatibility and reliability that may not be available from third-party manufacturers.
- What makes this differential set different from cheaper alternatives? — This ARRMA differential set features premium hardened steel gears, precision-manufactured components, reinforced case design with integrated strength features, and metal cross shafts rather than plastic alternatives. These engineering choices result in superior durability and consistent performance throughout the component's service life.
- How often will I need to replace my differential? — Proper maintenance including regular cleaning and oil changes will extend differential life significantly. However, aggressive driving, impacts, or exposure to water and dirt will accelerate wear. Having a replacement differential set available ensures you can get your RC car UK setup back on the track quickly if damage occurs.
