Key Features
- Genuine OEM ARRMA Component — These suspension arms are manufactured by ARRMA themselves, guaranteeing perfect fitment and compatibility with your Outcast 8S 8S BLX. Genuine parts maintain the exact suspension geometry and performance characteristics that ARRMA engineered into your truck, whereas cheap aftermarket alternatives can alter handling and introduce unpredictable behaviour.
- Pair of Rear Lower Arms — You receive a complete pair of left and right rear lower suspension arms in a single purchase, everything you need to service both sides of your vehicle's rear suspension in one transaction. This eliminates the hassle of ordering multiple items separately and ensures matched components for symmetrical suspension performance.
- Direct Compatibility with Outcast 4X4 8S BLX — These arms are engineered specifically for the ARRMA 1/5 Outcast 4X4 8S BLX EXB Brushless model, ensuring perfect fitment without any modification, adaption or drilling required. Simply remove your damaged arms and install these replacements for instant restoration of suspension integrity.
- Essential Wear Component — Suspension arms are among the most stressed components on any RC monster truck, especially one as powerful as the brushless 8S Outcast. These parts take the impact loads from jumps, bashing and aggressive driving, making them wear items that demand replacement as part of regular maintenance for any serious RC enthusiast.
- Maintains Factory Performance — Using genuine ARRMA suspension arms ensures your truck continues to handle exactly as ARRMA intended, preserving the suspension geometry, steering response and overall vehicle dynamics that make the Outcast 8S such a respected bashers platform in the ready to run RC market.
Technical Performance
The ARRMA Rear Lower Suspension Arms Z-ARA330590 are manufactured using durable materials engineered to withstand the extreme forces generated by the Outcast 4X4 8S BLX brushless powertrain. The 1/5 scale Outcast is one of ARRMA's most aggressive platforms, delivering exceptional performance through its brushless 8S LiPo compatibility and powerful drivetrain. The suspension arms must handle constant impact loads from high-speed driving, extreme jumps, and aggressive bashing across varied terrain. By replacing worn or damaged suspension arms with genuine ARRMA components, you restore the precise suspension geometry that allows your truck to maintain consistent handling, responsiveness and predictable behaviour across all driving conditions. These arms are essential maintenance items for any RC car UK owner running the Outcast 8S platform regularly, and keeping spare arms on hand ensures you can quickly return to driving after damage rather than waiting for delivery. The engineering and materials used in genuine ARRMA spares reflect decades of off-road RC development and real-world testing across professional racing and extreme bashing environments.

Frequently Asked Questions
- What vehicles do these ARRMA suspension arms fit? — These rear lower suspension arms are designed specifically for the ARRMA 1/5 Outcast 4X4 8S BLX EXB Brushless Stunt Truck. They are genuine OEM ARRMA components and will fit without modification or adjustment. If you own a different ARRMA model, please verify the part number matches your vehicle's specifications before ordering.
- Why do I need to replace my suspension arms? — Suspension arms are wear items that suffer constant stress from driving impacts, jumps, and aggressive bashing. Over time, they can bend, crack, or develop stress fractures that compromise handling and safety. Replacing damaged arms restores your truck's suspension geometry and ensures predictable, responsive handling. For anyone running a brushless 8S RC truck regularly, keeping replacement arms on hand is essential maintenance.
- Are these genuine ARRMA parts or aftermarket replacements? — These are genuine OEM ARRMA components manufactured by ARRMA themselves. They carry the official ARRMA part number Z-ARA330590 and EAN code 5052127033909, guaranteeing authenticity and perfect fitment. Genuine parts maintain factory suspension geometry, whilst cheap aftermarket alternatives can alter your truck's handling and reliability.
- What is the difference between front and rear lower suspension arms for the Outcast? — The Outcast 4X4 8S has different suspension arm designs for front and rear positions due to the different loads and handling requirements at each end of the vehicle. These are specifically the rear lower arms; if you need front replacements, you should order the front lower arms separately using part number Z-ARA330589.
- Do I need any tools or special knowledge to install these? — Installation of suspension arms is a straightforward maintenance task that most RC enthusiasts can complete with basic tools. You will need to remove your damaged arms (typically secured with ball studs and screws) and install the new ARRMA arms in the same location. If you are unsure about installation, RC Model Shop's experienced team can provide guidance and support.
- Can I upgrade to aftermarket arms like RPM? — Yes, third-party manufacturers like RPM produce alternative suspension arms for the Outcast 8S platform, often offering different materials or designs. However, if you want direct OEM replacement parts that maintain factory specifications exactly, genuine ARRMA components are the correct choice. Both options have merit depending on your performance goals and driving style.
