Associated Ballstud Washers 5.5 x 0.5mm Blue Aluminium 10 Pack AS31381

Overview

The Associated Ballstud Washers 5.5 x 0.5mm in blue aluminium represent an essential component for any serious RC enthusiast working with 1/10 scale vehicles. These precision-engineered shims are now available separately, making it easier than ever to source replacement parts or upgrade your RC car UK setup without purchasing an entire assembly. Whether you're fine-tuning suspension geometry on your on-road racer or maintaining your competition-grade buggy, these ballstud washers deliver the precision fit and durability that Associated is renowned for across the hobby.

Manufactured from blue aluminium, these washers feature a small outside diameter that makes them ideal for confined spaces on modern 1/10 scale chassis designs. If you're involved in on-road RC racing or simply want to keep your RC car in peak condition, having a spare set of ballstud washers ensures you can quickly address wear or fine-tune your setup without downtime. The pack of ten gives you plenty of spares for ongoing maintenance or experimental setup changes.

RC Model Shop stocks genuine Associated components for customers across the UK who demand nothing but authentic, quality parts for their RC vehicles. These washers are compatible with an extensive range of Associated models and are an ideal addition to any RC enthusiast's spare parts collection.

Key Features

• Blue Aluminium Construction — Manufactured from lightweight blue aluminium that resists corrosion whilst maintaining excellent durability, ensuring these washers will withstand repeated use in demanding on-road conditions without degrading or losing their dimensional accuracy over time.
• Precision 5.5 x 0.5mm Dimensions — These washers are engineered to exact specifications that match Associated ballstud assemblies, ensuring a perfect fit that maintains consistent suspension geometry and prevents lateral movement that could compromise handling performance.
• Small Outside Diameter Design — The compact profile allows these shims to fit in tight spaces around ballstud connections, making them ideal for modern 1/10 scale on-road chassis where space is at a premium and precision fitment is critical.
• Pack of 10 Pieces — Ten washers per pack means you have plenty of spares for maintenance, experimentation with different shim stacks, or building up your spare parts inventory without needing to purchase multiple packs.
• Common for On-Road Applications — These washers are specifically designed for on-road RC car setups, where suspension adjustments through shim stacking are a fundamental part of competitive chassis tuning and performance optimisation.
• Compatible with Multiple Associated Models — Whether you're running a B64, B6.1, B6.1D, B6.2, B6.2D, B6.3, B6.4, B6.4D, B74, B74.1, B74.2, B74.2D, T6.1, T6.2, T6.4, F6, DR10, DR10M, RC8B3.2E, RC10SC6.1, RC10SC6.2, SC6.4, Pro2 SC10, Pro2 LT10SW, Pro2 DK10SW Dakar, Pro4 SC10, PROSC10, Rival MT10, Reflex DB10, RB10, RB10 Retro, SR10, SC10SW, RC10CC Classic Clear, DC10, RC10DR or any compatible Associated on-road platform, these washers will integrate seamlessly.

Technical Performance

These Associated Ballstud Washers represent the kind of precision engineering that separates genuine component manufacturers from aftermarket alternatives. Constructed from blue aluminium, they deliver a perfect balance of lightweight construction and structural rigidity. The 5.5mm outer diameter with a 0.5mm thickness has been engineered to provide optimal shim stacking capability in on-road RC suspension geometry adjustments. When used correctly in suspension assemblies, these washers allow drivers to fine-tune camber, caster, and other critical alignment parameters that directly impact cornering speed, tyre wear patterns, and overall handling balance on tarmac surfaces. The small outside diameter design is particularly crucial in modern 1/10 scale on-road platforms where space around ballstud connections is extremely limited. The blue aluminium finish provides excellent corrosion resistance compared to raw metal, meaning these washers maintain their dimensional stability and appearance even with regular use and exposure to moisture. Whether you're setting up for carpet racing, asphalt track competition, or high-speed on-road bashing, having the correct shim thickness and quantity is fundamental to achieving optimal suspension performance. These washers are standard fitment components across an enormous range of Associated on-road and short course platforms, making them one of the most universally useful spare parts you can stock.

Frequently Asked Questions

• Are these ballstud washers suitable for all 1/10 scale RC cars? — These washers are specifically designed for Associated 1/10 scale on-road vehicles and are confirmed compatible with a comprehensive range of Associated models including the B-series, T-series, F6, SC-series, and many others. If you're running a non-Associated platform, you should verify the ballstud dimensions before purchasing, as different manufacturers may use different specifications.
• What is the purpose of ballstud washers in RC suspension? — Ballstud washers function as shims that stack around ballstud connections to adjust suspension geometry precisely. By changing the number or thickness of washers, you can alter camber, caster, and other alignment parameters without replacing entire suspension components. This is particularly important in competitive on-road racing where small adjustments can significantly impact lap times and handling consistency.
• How many washers should I use in my suspension setup? — The optimal number of washers depends on your specific RC car model, track surface, and desired handling characteristics. Consult your Associated model manual for recommended starting shim thicknesses, then adjust based on your driving preferences and track conditions. Having multiple spare washers allows you to experiment safely.
• Why are blue aluminium washers used instead of steel? — Aluminium offers a superior strength-to-weight ratio compared to steel whilst remaining easy to machine to precise tolerances. The blue finish provides corrosion resistance without adding significant weight to your suspension components, which is critical in 1/10 scale racing where every gram matters for performance.
• Can I mix different thickness washers in the same ballstud? — Yes, stacking different thickness washers is a standard practice in RC suspension tuning. This flexibility allows you to achieve specific suspension geometry adjustments without needing washers in every possible thickness increment.
• Are these original Associated parts or aftermarket replacements? — These are genuine Associated component parts, engineered and manufactured to the same specifications as the washers supplied in new Associated vehicles. You're buying authentic parts from the original equipment manufacturer.
