Technical Performance
The ARRMA Washer, 4.2x12x1mm represents precision engineering designed for the demanding world of RC motorsport and off-road recreation. With an inner diameter of 4.2mm and outer diameter of 12mm, these washers provide optimal load distribution across a wide surface area while remaining compact enough to fit within tight mechanical spaces. The 1mm thickness is engineered to provide adequate spacing and load distribution without adding unnecessary bulk or weight to your RC vehicle's mechanical assembly. These washers are manufactured to exacting tolerances, ensuring consistent performance across the set of four pieces. The material composition is selected to withstand the mechanical stresses, vibration, and environmental exposure that RC vehicles experience during regular use, whether that involves high-speed bashing, competitive racing, or technical rock crawling. When used with ARRMA's brushless motor systems and advanced suspension geometry found in vehicles like the 8S Kraton and Outcast trucks, these washers play an integral role in maintaining proper component alignment and preventing accelerated wear on expensive bearings, suspension arms, and driveline components. Proper washer placement ensures that fasteners distribute their clamping force evenly, preventing stress concentration that could lead to component failure or cracking under the extreme loads experienced during aggressive driving.

Frequently Asked Questions
- What is the purpose of washers in my RC car and why do I need replacements? — Washers distribute the load from fasteners across a wider surface area, preventing damage to softer materials and ensuring even pressure distribution across mechanical joints. Over time, washers can wear, deform, or become damaged from vibration and environmental exposure, which is why having genuine replacement washers is essential for maintaining your RC car's performance and preventing more serious mechanical damage.
- Will these ARRMA washers fit my specific RC model? — These washers are compatible with the ARRMA 1/5 Kraton 4X4 8S BLX EXB Brushless Monster Truck RTR and the ARRMA 1/5 Outcast 4X4 8S BLX EXB Brushless Stunt Truck RTR. If you own either of these high-performance brushless RC vehicles, these washers are designed as genuine replacement parts. For other ARRMA models, we recommend checking your vehicle's parts manual or contacting our knowledgeable team at RC Model Shop to verify compatibility.
- Are these suitable for competition or just casual bashing? — These genuine ARRMA washers are suitable for both competition-grade use and casual recreational bashing. Because they're manufactured to ARRMA's original specifications, they maintain the precise tolerances and durability required for high-performance 8S brushless RC vehicles that experience significant mechanical stress during competitive events or aggressive off-road driving.
- How often should I replace washers on my RC car? — The frequency of washer replacement depends on your usage intensity, driving style, and environmental conditions. Regular inspection as part of routine maintenance will help you identify when washers have become worn or deformed. If you notice any loose components, unusual vibration, or visible damage to fastening points, it's time to replace the washers. Serious enthusiasts who run their RC cars frequently should keep spare washers on hand as part of their maintenance kit.
- Why should I buy genuine ARRMA washers rather than generic alternatives? — Genuine ARRMA washers are engineered to precise specifications that ensure perfect fit, proper load distribution, and reliability with your ARRMA vehicle's mechanical systems. Generic or aftermarket washers may vary in dimensions, material quality, or tolerances, potentially compromising the performance, safety, or longevity of your RC car. When you're investing in quality RC equipment, using genuine replacement parts ensures consistent performance and maintains your vehicle's resale value.
