This high-quality radio box set is specifically engineered to safeguard your receiver from the harsh conditions that come with serious RC bashing, whether you're driving your 1/10 scale monster truck through muddy terrain or pushing your short course truck to its limits on rocky ground. If you own an ARRMA 223S model such as the Big Rock, Granite, or Senton, this replacement receiver box is a genuine spare part designed to restore your vehicle to factory condition or upgrade an ageing chassis with professional-grade protection.
Whether you're a seasoned RC basher looking for replacement parts after wear and tear, or someone building a custom setup, the ARRMA Radio Box Set provides the robust protection your electronics deserve. This is not a basic plastic enclosure — it's a precision-engineered component that combines professional materials with thoughtful design features that serious RC car UK enthusiasts rely on. The set includes everything needed to properly house your receiver and ESC, with integrated mounts and wire management to keep your electronics safe from dirt, water, and damage during intense off-road driving sessions.
ARRMA has built a reputation for creating tough, high-performance RC vehicles designed to bash hard and last long, and this receiver box set exemplifies that commitment to quality. When you invest in this replacement radio box, you're choosing proven protection from a manufacturer that understands what it takes to keep RC electronics safe in demanding conditions. The Radio Box Set 4x4 is the professional choice for maintaining your ARRMA 4WD monster truck, short course truck, or other 4x4 model with confidence.
Key Features
- Specially Designed Water and Dirt Protection — The receiver box is purpose-built to shield your radio receiver from moisture, dust, mud, and water splash that naturally occurs during off-road RC driving, keeping your expensive electronics safe and functional through countless bashing sessions.
- Precision Rubber Seals — Manufactured with high-quality rubber seals for the lid and servo/ESC wiring, these seals create a tight barrier against dirt and moisture ingress, ensuring your radio system stays protected in wet or dusty conditions common in UK RC terrain.
- Integrated Servo Mount — The lower receiver box features a pre-moulded integrated servo mount, eliminating the need for separate mounting brackets and ensuring your servo is securely and properly positioned within the box.
- Pre-Moulded ESC Mounting Holes — The lid comes with mounting holes specifically designed for the ESC, allowing fast and hassle-free installation without drilling or guessing where components should sit.
- Strong Composite Material Construction — Built from durable composite materials, this receiver box delivers long-lasting durability that withstands the impacts, vibrations, and environmental stresses of regular RC bashing without cracking or degrading.
- Integrated Aerial Wire Mount — A dedicated aerial wire mount is moulded into the box, allowing you to securely position your radio receiver aerial for optimal signal reception whilst keeping the wire organised and protected from damage.
- Motor Wire Guide — The included motor wire guide keeps your motor wiring tidy and organised, preventing loose cables from fouling on suspension components or getting caught during operation, which improves reliability and simplifies maintenance.
- Precision Hardware Holes — All receiver box hardware mounting points are precision manufactured, enabling fast and hassle-free servicing when you need to access or upgrade your radio system components.
Technical Performance
This ARRMA Radio Box Set is engineered with the exacting standards expected from a professional RC manufacturer. The composite material construction provides the perfect balance between weight savings and structural rigidity, ensuring the box protects your electronics without adding excessive mass to your chassis. The precision rubber seals are the critical element here — they create a moisture barrier that keeps water and mud out of your receiver and servo connections, which is essential for reliable operation in the wet UK climate or after racing through muddy terrain. The integrated servo mount and pre-moulded ESC holes demonstrate ARRMA's attention to detail, eliminating alignment issues and ensuring proper component positioning. The motor wire guide feature is particularly valuable for keeping wiring organised within tight spaces, reducing the risk of shorts or damage from moving suspension parts. The aerial wire management system allows you to optimise radio reception by positioning your aerial precisely, which is crucial for maintaining consistent control over your brushless RC model, whether you're running a high-speed 223S system or upgrading an older chassis. The box is compatible with ARRMA's popular 1/10 scale 4WD models including the Big Rock 223S DSC, Granite 223S DSC, and Senton 223S BLX short course trucks, making it an essential spare part for anyone running these vehicles regularly.

Frequently Asked Questions
- What ARRMA vehicles is this radio box set compatible with? — This Radio Box Set Z-AR320400 is specifically designed for ARRMA 1/10 scale 4WD models, including the Big Rock 223S DSC 4x4 (available in Black, Blue, and Green), the Granite 223S DSC 4x4 (available in Blue, Gun Metal, and Red), and the Senton 223S BLX 4x4 Short Course Truck (available in Red, Yellow, and Blue/Purple variants). If you own any of these brushless monster trucks or short course trucks, this is the genuine replacement receiver box designed by ARRMA for your vehicle.
- Why do I need a replacement radio box for my RC car UK? — If your current receiver box has become damaged through impacts, develops leaks allowing water or mud inside, or if seals have deteriorated after heavy use, a replacement radio box is essential to protect your expensive receiver and servo electronics. Even minor water ingress can cause corrosion and failure, making this protection critical for reliable operation.
- How do the rubber seals protect my receiver in wet conditions? — The precision-manufactured rubber seals create a tight barrier between the receiver box and the external environment. The lid seal and the servo/ESC wire seal work together to prevent water splash, mud spray, and moisture from entering the box where your sensitive radio equipment is housed, which is particularly important when bashing in UK conditions or after wet terrain driving.
- Is this set suitable for replacing a damaged original receiver box? — Yes, absolutely. This is a genuine ARRMA spare part designed as a direct replacement for the receiver box that comes with new vehicles or replacement for damaged boxes on existing vehicles. The integrated servo mount, pre-moulded ESC holes, and all included seals match the factory specification exactly.
- What tools do I need to install this receiver box? — The design includes precision hardware holes for fast and hassle-free installation. You'll need basic RC maintenance tools such as a small Phillips screwdriver and potentially a servo driver if you need to remove and reposition your servo, but installation is straightforward and follows standard RC assembly practices.
- Can I use this box with aftermarket receivers or servos? — The integrated servo mount and pre-moulded holes are designed for ARRMA's standard components, but the box itself is large enough to accommodate most standard-sized RC receivers and servos. Always verify that your aftermarket electronics fit within the box dimensions before installation.
