Overview
The ARRMA Washer 7.1x11x0.5mm (4) 4x4 is an essential replacement hardware component designed for RC car enthusiasts and serious hobbyists across the UK. These precision-manufactured steel washers are genuine ARRMA parts that come as a pack of four, making them ideal for maintaining and servicing your RC vehicle collection. Whether you own an ARRMA brushless RC monster truck, short course truck, stadium truck, buggy, or speed truck, these washers provide critical support for your model's mechanical assembly and are a must-have spare part for any RC modeller's toolkit.
These high-quality steel washers serve a vital function in RC car assembly and maintenance. Washers distribute loads evenly across fastener connections, preventing damage to softer materials and ensuring that bolts and screws maintain consistent pressure over time. This is particularly important in RC vehicles where vibration, impacts, and continuous operation can loosen fasteners. By keeping a supply of these replacement washers on hand, you ensure that your RC 4x4 truck, buggy, or stadium truck remains in peak condition and ready for action whether you're racing competitively, bashing at weekends, or enjoying casual track days with friends.
Compatible with an extensive range of ARRMA vehicles including the Big Rock, Fury, Gorgon, Granite, Kraton, Outcast, Quake, Senton, Vorteks, Infraction, Mojave, Typhon, and Vendetta models, these washers are a universal maintenance component that every serious RC car UK enthusiast should have in stock. ARRMA's commitment to precision manufacturing means these washers are engineered to exact tolerances, ensuring they fit perfectly every time and maintain the structural integrity of your model's assembly.
Key Features
- Precision-Manufactured Steel Construction — These washers are manufactured to exacting tolerances using high-quality steel, ensuring consistent fit and reliable performance across all your ARRMA RC vehicles without gaps or misalignment.
- Pack of Four Washers — The set includes four individual washers, providing multiple replacement options so you can service multiple connection points or maintain a ready supply for future maintenance and repairs.
- Exact Dimensional Specification — With an inside diameter of 7.1mm, outside diameter of 11.0mm, and thickness of 0.5mm, these washers are engineered to mate perfectly with specific fastener combinations used throughout ARRMA's 4x4 vehicle range.
- Long-Lasting Durability — Strong and durable steel construction guarantees long-lasting performance in all conditions, whether you're driving in wet weather, sandy environments, muddy terrain, or dry track conditions, making these washers reliable for demanding RC applications.
- Hassle-Free Servicing — Because these are genuine ARRMA parts manufactured to original specifications, installation is straightforward and requires no modifications, adjustments, or compatibility concerns whatsoever.
- Universal Compatibility Across ARRMA Range — These washers are standard parts for dozens of ARRMA models including brushless monster trucks, short course trucks, stadium trucks, buggies, and speed trucks, making them an essential multi-purpose spare.
Technical Performance
The ARRMA Washer 7.1x11x0.5mm represents precision engineering applied to a fundamental RC car component. These steel washers play a critical role in the mechanical reliability of your brushless RC monster truck, short course truck, stadium truck, buggy, or speed truck. The 7.1mm inside diameter accommodates standard fasteners used throughout ARRMA's vehicle designs, whilst the 11.0mm outside diameter provides adequate load distribution across mounting surfaces. The 0.5mm thickness is precisely calculated to take up tolerance gaps and ensure consistent fastener pressure without creating binding or interference issues. Steel construction provides excellent hardness and durability, resisting deformation even under the vibration and stress experienced during high-speed running, jumps, impacts, and aggressive terrain driving. These washers maintain their structural integrity across temperature variations and resist corrosion better than softer metals, making them suitable for use in all weather conditions including winter RC car racing in the UK. Whether you're running a 4x4 off-road truck, a stadium truck on tarmac, or a high-speed RC buggy, these washers ensure that critical fastener connections remain secure and reliable throughout your driving sessions.

Frequently Asked Questions
- What ARRMA RC models are these washers compatible with? — These washers are standard parts for an extensive range of ARRMA vehicles including the 1/10 Big Rock, Fury, Gorgon, Granite, Kraton, Outcast, Quake, Senton, Vorteks, and Senton Boost models, as well as 1/8 scale Infraction, Mojave, Typhon, and Vendetta variants. They are designed for both brushless and brushed versions across 2WD and 4WD configurations.
- Why would I need replacement washers for my RC 4x4 truck? — Washers are critical components that distribute load evenly across fastener connections, preventing damage to softer chassis materials and ensuring bolts remain tight under the vibration and impacts that occur during RC car operation. Over time, washers can wear, compress, or become lost during maintenance, making spares essential for keeping your ready to run RC truck or buggy in perfect condition.
- Are these genuine ARRMA parts? — Yes, these are genuine ARRMA replacement parts manufactured to original specifications, ensuring perfect compatibility and reliability with your RC vehicle without any need for modifications or adjustments.
- Do these washers require any special tools or expertise to install? — No, installation is straightforward and requires only basic tools such as an Allen key or socket set that you likely already use for RC car maintenance. Simply remove the old fastener, place the new washer on the bolt or screw, and reinstall, ensuring the fastener is secure but not overtightened.
- Can I use these washers on other RC vehicles besides ARRMA models? — The 7.1 x 11 x 0.5mm dimensions are common in many RC car brands, so these washers may fit other models using similar fastener specifications. However, they are specifically designed and tested for ARRMA vehicles, and we recommend confirming compatibility with your vehicle's parts diagram before using them on other brands.
- How many washers should I keep in stock? — This four-pack provides a useful supply for maintenance and repairs. Most RC enthusiasts find it worthwhile to keep multiple packs on hand, as washers can be easily lost and multiple fastener points throughout your vehicle may benefit from fresh washers during a full service.
