Overview
The ARRMA Diff Case Set Z-ARA311154 is an essential replacement or upgrade component for owners of ARRMA's 1/10 scale Kraton and Outcast 4X4 4S V2 BLX models. Whether you're an experienced RC enthusiast operating a brushless RC monster truck or stunt truck in the UK, or someone looking to maintain and repair their high-performance RC vehicle, this precision-engineered differential case set delivers the quality and reliability that ARRMA is renowned for. This is a genuine OEM spare part designed to restore your vehicle to factory specifications or to serve as a critical component when building or upgrading your RC car's drivetrain system.
Differential cases are among the most important components in any RC vehicle's transmission system, responsible for distributing power evenly to the drive wheels whilst allowing them to rotate at different speeds during cornering. The ARRMA Diff Case Set provides everything you need to maintain optimal performance and handling in your 4WD RC monster truck or stunt truck. When your differential case shows signs of wear or damage from intense bashing, racing, or off-road use, this genuine replacement ensures your vehicle continues to perform at its best without compromise.
For anyone serious about RC driving in the UK—whether you're tackling rough terrain, racing on tracks, or enjoying weekend bashing—having quality spare parts on hand is essential. This composite diff case set represents the engineering excellence that ARRMA builds into every component, ensuring your RC model truck maintains its performance characteristics and handling dynamics long after the initial purchase.
Key Features
- Precision Manufactured Construction — Every component in this diff case set is manufactured to exacting tolerances, ensuring accurate fit and alignment of all differential parts, which is critical for smooth power delivery and predictable handling in your RC monster truck or stunt truck.
- High-Quality Composite Material — The case is engineered from durable composite material that balances strength with lightweight performance, providing long-lasting durability through countless hours of bashing, racing, and off-road adventures without degradation or failure.
- Complete Gasket and Hardware Included — This set comes with the essential diff case gasket and all necessary assembly screws (four M3 x 16mm flat head screws), eliminating the need to source additional components and ensuring you have everything required for a complete installation.
- Genuine ARRMA OEM Component — As an official ARRMA replacement part, this diff case set guarantees compatibility and performance consistency with your Kraton 4X4 4S V2 or Outcast 4X4 4S V2 BLX, maintaining the engineering integrity of your vehicle.
- Easy Installation — Designed as a drop-in replacement, this diff case set installs directly into your existing vehicle without modification, making repairs and maintenance straightforward for both beginners and experienced RC enthusiasts.
Technical Performance
The ARRMA Diff Case Set Z-ARA311154 is engineered specifically for the demands of high-performance 1/10 scale 4WD RC vehicles. The composite construction strikes an optimal balance between rigidity and weight, essential for maintaining accurate power distribution in brushless-powered monster trucks and stunt trucks that demand precise handling characteristics. The precision manufacturing ensures minimal play or tolerance stack-up between the case and its mating components, which is absolutely critical for maintaining consistent differential action during acceleration, braking, and cornering. The included gasket provides a reliable seal that prevents fluid leakage and contamination of the differential internals, whilst the four M3 x 16mm flat head assembly screws are specifically engineered to provide secure clamping force without over-torquing. This component is compatible with both the Kraton 4X4 4S V2 BLX Speed Monster Truck (available in green) and the Outcast 4X4 4S V2 BLX Stunt Truck (available in red and gunmetal variants), ensuring broad compatibility across ARRMA's premium 4S brushless range. The robust construction handles the substantial torque output of modern brushless motors found in RTR RC cars whilst maintaining the precise tolerances necessary for smooth operation and predictable performance in competitive racing or recreational bashing environments.

Frequently Asked Questions
- Is the ARRMA Diff Case Set suitable for both Kraton and Outcast models? — Yes, this Z-ARA311154 set is fully compatible with both the ARRMA 1/10 Kraton 4X4 4S V2 BLX Speed Monster Truck and the ARRMA 1/10 Outcast 4X4 4S V2 BLX Stunt Truck, regardless of colour variant. Both vehicles use identical differential systems and this is a genuine OEM replacement part for either model.
- What additional parts do I need to complete the differential assembly? — This diff case set includes the case, cap, gasket, and assembly screws, but requires two additional ARRMA components for complete assembly: part #ARA311152 and part #ARA311153. Check the ARRMA parts diagrams or contact us to identify exactly which internal differential components you need based on your specific repair or upgrade requirements.
- Can beginners install this diff case set themselves? — Yes, the installation is straightforward for anyone with basic mechanical skills and the right tools. The set is designed as a direct replacement component, and installation instructions are typically available from ARRMA. However, if you're unfamiliar with differential assembly, we recommend consulting your vehicle's manual or seeking assistance from an experienced RC technician to ensure proper alignment and gasket seating.
- Is this a genuine ARRMA part or an aftermarket replacement? — This is a genuine ARRMA OEM (original equipment manufacturer) component, which means it meets all the engineering specifications and quality standards that ARRMA establishes for their vehicles. Genuine parts ensure compatibility, durability, and reliability that aftermarket alternatives may not provide.
- Why would I need to replace my diff case? — Differential cases may require replacement due to normal wear from extended use, damage from impacts or crashes, or stripped threads in the mounting area. Additionally, some RC enthusiasts replace their differential cases when upgrading to different internal gear ratios or when rebuilding their vehicle's complete drivetrain for improved performance.
- Does this set include everything needed for installation? — This set includes the case, cap, gasket, and all assembly screws, but you will need the internal differential components (#ARA311152 and #ARA311153) to complete a fully functional differential assembly. You'll also need basic tools such as screwdrivers and possibly a hex driver set for installation.
