Overview
The Associated Washers 7.8 x 3.5 x 0.5mm in blue aluminium are essential precision components for RC car enthusiasts across the UK who demand accurate setup and fine-tuning capabilities. This pack of ten high-quality washers represents the gold standard in RC car shimming and spacing, offering builders and racers the tools they need to achieve consistent, repeatable performance on their vehicles. Whether you're fine-tuning a competitive 1/10 or 1/8 scale RC buggy, truck, or truggy, these blue aluminium washers provide the precision spacing required for professional-grade setup adjustments.
Associated is a globally recognised manufacturer of premium RC components, and these washers exemplify their commitment to quality engineering and precision manufacturing. The blue aluminium construction provides excellent durability whilst remaining lightweight, ensuring your RC car maintains optimal performance characteristics without unnecessary weight penalties. For RC enthusiasts in the UK looking to dial in their ride height, wheelbase adjustment, and chassis geometry, these washers are an indispensable addition to any RC toolbox. They work brilliantly as rear hub spacers for wheelbase adjustment on popular models like the RC8B3 and RC8T3 series, but their versatility extends to countless other applications across the entire Associated range.
Available in a convenient pack of ten, these 7.8 x 3.5 x 0.5mm washers are just one thickness option in the broader Associated shimming range, which also includes 1mm and 2mm variants, allowing you to build the exact stack height needed for your preferred setup. Whether you're a seasoned RC car UK competitor or an enthusiast looking to optimise your weekend basher, understanding how to use quality shimming components like these can make the difference between an average setup and a championship-winning configuration.
Key Features
- Precision thickness of 0.5mm — This exact thickness specification ensures accurate spacing adjustments when fine-tuning your RC car's geometry and clearances, allowing you to make incremental changes that directly impact handling and performance without overshooting your setup targets.
- Blue aluminium construction — The high-quality blue aluminium material provides an excellent balance of strength and weight, resisting corrosion whilst maintaining the durability needed for repeated assembly, disassembly, and adjustment cycles typical of serious RC car maintenance and tuning.
- Pack of ten washers — Ten pieces per pack gives you enough washers to complete multiple shimming projects, adjust both front and rear hubs, or maintain a stock of spares for ongoing setup experimentation and refinement on your 1/10 or 1/8 scale vehicles.
- Compatible with RC8B3 and RC8T3 series — These washers are specifically suggested for use as rear hub spacers on the RC8B3 and RC8T3 series vehicles, making them an ideal choice if you own or operate any of these popular Associated platform models, though their universal design makes them suitable for countless other vehicles.
- Versatile shimming application — Beyond hub spacing, these washers can be employed anywhere precise spacing is required across 1/10 and 1/8 scale RC cars, including suspension adjustments, motor mount clearances, and any other area where you need to fine-tune your vehicle's mechanical geometry.
- Part of a complete shimming system — Associated offers complementary 1mm and 2mm thickness options, allowing you to layer different thicknesses and build custom stack heights tailored to your exact setup requirements and tuning philosophy.
Technical Performance
The Associated Washers 7.8 x 3.5 x 0.5mm represent the engineering precision expected from a top-tier RC component manufacturer. The 7.8mm outer diameter and 3.5mm inner bore are engineered to fit standard RC car hub and suspension mounting points, whilst the exact 0.5mm thickness provides the precise spacing increment needed for meaningful setup adjustments. The blue aluminium material selection reflects professional-grade manufacturing standards—aluminium offers superior strength-to-weight ratio compared to plastic or steel alternatives, meaning your RC car benefits from added spacing without suffering any performance penalty from extra mass. The blue colour coding makes these washers immediately identifiable in your parts box, reducing confusion when selecting the correct thickness during setup sessions. Across the full Associated shimming range (0.5mm, 1mm, and 2mm options), builders can achieve virtually any required stack height through intelligent layering. These washers are precision-manufactured to exacting tolerances, ensuring consistent performance across all ten units in the pack—critical for maintaining the symmetrical geometry that separates a well-dialled RC car from one with handling inconsistencies. Whether you're adjusting wheelbase on your RC8B3, fine-tuning suspension geometry on a competitive 1/10 buggy, or optimising hub clearances on an 1/8 truggy, the repeatability and accuracy of these components directly contribute to your vehicle's on-track performance and setup stability.

Frequently Asked Questions
- What are these Associated washers used for? — These washers serve as precision spacing and shimming components for RC cars, most commonly used as rear hub spacers for wheelbase adjustment on vehicles like the RC8B3 and RC8T3 series. They're essential for fine-tuning suspension geometry, adjusting clearances, and achieving the exact spacing required for optimal handling and performance across 1/10 and 1/8 scale vehicles.
- Can I use these washers on RC cars other than Associated models? — Yes, whilst these washers are specifically suggested for the RC8B3 and RC8T3 series, their universal design makes them compatible with virtually any 1/10 or 1/8 scale RC car where precise 0.5mm spacing is required, including buggies, trucks, and truggies from various manufacturers, as long as the 7.8mm outer diameter and 3.5mm bore match your vehicle's mounting points.
- What thickness options are available in the Associated shimming range? — Associated manufactures these washers in three different thicknesses: 0.5mm (this product), 1mm, and 2mm, allowing you to combine multiple washers to build custom stack heights and achieve any spacing requirement your setup demands.
- Why is blue aluminium better than other washer materials? — Aluminium provides an excellent strength-to-weight ratio compared to plastic or steel, meaning these washers are durable and reliable whilst adding minimal weight to your RC car—a critical consideration when every gram counts in competitive racing or when optimising your vehicle's performance characteristics.
- How many washers do I need for a typical setup adjustment? — The number of washers required depends on your specific tuning needs; some adjustments might require just one or two washers per hub, whilst others might involve stacking multiple washers to achieve the desired spacing. The ten-pack provides plenty for multiple adjustments or to maintain spare inventory.
- Are these washers compatible with 1/10 and 1/8 scale RC cars? — Yes, these washers are designed for use across both 1/10 and 1/8 scale vehicles wherever accurate 0.5mm spacing is needed, making them a universal tuning component for serious RC enthusiasts.
