These blue aluminium bulkhead washers are particularly valued by RC car enthusiasts in the UK because they provide uniform, precise shimming solutions for vehicles requiring exact 2.0 mm thickness and 7.8 mm outer diameter specifications. The large outside diameter design makes them ideal for a comprehensive range of 1/10 scale RC vehicles, from short course trucks and off-road buggies to touring cars and stadium trucks. If you're building or maintaining an RC car in the UK that demands factory-spec components and professional-grade hardware, these washers ensure your setup maintains the precise tolerances necessary for optimal performance and handling characteristics.
Manufactured by Team Associated and identified by part number AS31386, these blue aluminium bulkhead washers represent a tidy, uniform hardware option that keeps your RC car's assembly looking professional whilst maintaining the exact measurements your vehicle's manual specifies. Rather than improvising with mismatched washers or settling for components that don't quite fit your application, these genuine Associated bulkhead washers give you the confidence that your RC car's mechanical setup is exactly as the engineers intended.
Key Features

Technical Performance
These bulkhead washers represent the kind of precision hardware that separates professional RC racing setups from casual builds. Manufactured from aluminium, a material chosen specifically for its excellent strength-to-weight characteristics, these washers deliver durability without adding unnecessary mass to your 1/10 scale RC car. The 7.8 mm outer diameter provides substantial contact area for reliable clamping of bulkhead and arm mount assemblies, critical for maintaining rigid chassis geometry during hard cornering, jumps and high-speed runs. The 2.0 mm thickness is engineered to work in conjunction with the suspension geometry and component tolerances across Team Associated's entire vehicle range, from the RC10B series buggies through to the TC touring cars, SC short course trucks and specialised variants. The blue aluminium finish resists corrosion from moisture exposure, sweat and track chemicals, making these washers reliable whether you're racing indoors in climate-controlled facilities or running your RC car outdoors where weather and environmental factors present genuine challenges. Each washer is manufactured to consistent tolerances, ensuring that all ten pieces in your pack perform identically, eliminating the variability that comes from mixing different brands or older used components. Whether you're setting up a new RC car straight from the box or restoring a competition platform, these bulkhead washers ensure your mechanical assemblies maintain factory-specification tightness and alignment throughout your racing season.

Frequently Asked Questions
- What are bulkhead washers used for in RC cars? — Bulkhead washers are precision shims used in RC car construction to adjust and maintain correct spacing between suspension arms, bulkheads and drivetrain components. They're essential for tuning your RC car's geometry, ensuring suspension movement is free and smooth, and maintaining proper pivot point alignment for optimal handling and performance on the track or off-road course.
- Are these genuine Team Associated parts? — Yes, these bulkhead washers are genuine Team Associated components manufactured to OEM specifications. Identified by part number AS31386 and barcode 784695313866, they're authentic factory hardware rather than third-party replacements, ensuring they meet the exact tolerances and quality standards Team Associated engineers designed into your RC car.
- Will these washers fit my RC car? — These 7.8 x 2.0 mm bulkhead washers are specified as compatible with a comprehensive range of Team Associated 1/10 scale vehicles. However, different models may require different washer thicknesses and sizes for different assembly points. Always consult your specific RC car's manual to confirm the correct washer specifications for each bulkhead and arm mount location before installation.
