Key Features

• Blue Anodised Aluminium Construction — The sleeves are manufactured from high-grade aluminium that has been anodised in the signature Factory Team blue finish, providing both durability and visual appeal. This material choice offers superior strength whilst maintaining a lighter weight profile compared to the original steel sleeves.
• Significant Weight Savings of 1.8g Per Sleeve — Each sleeve reduces weight by approximately 1.8 grams compared to stock steel sleeves (part number AS81548). This might sound modest, but weight reduction in critical suspension components directly improves acceleration, deceleration, and handling response on the track or trail.
• Factory Team Upgrade Part — These sleeves are developed and manufactured by Team Associated's Factory Team division, meaning they meet the same exacting standards used in competition racing. You're not buying an aftermarket copy – you're buying genuine OEM quality components designed by the people who build championship-winning RC buggies.
• Direct Replacement for Stock Steel Sleeves — The sleeves fit perfectly in place of the original AS81548 components, requiring no modification or additional parts. Installation is straightforward for anyone with basic RC maintenance skills, making this an accessible upgrade for both beginners and experienced builders.
• Compatible with Multiple RC8B4 and RC8T4 Variants — Whether you run the nitro or electric versions of these platforms, whether it's the original RC8B4 or the newer RC8B4e, or the truck-platform RC8T4 and RC8T4e, these sleeves integrate perfectly with your existing CVA (Centre Vertical Axle) drivetrain.

Technical Performance

The TEAM ASSOCIATED RC8B4 FT CVA AXLE SLEEVES represent precision engineering at its finest. By replacing heavy steel sleeves with blue anodised aluminium alternatives, you're optimising the rotating mass in your RC buggy's drivetrain – a critical factor in high-performance RC racing. The CVA (Centre Vertical Axle) system is Team Associated's proven drivetrain architecture, found on the RC8B4 and RC8T4 series buggies and trucks. These sleeves work within that system to reduce unsprung weight, which translates directly to better suspension compliance, quicker directional changes, and improved traction on varied terrain. The 1.8g weight saving per sleeve might seem small in isolation, but across the entire vehicle – especially when multiplied by the number of axle sleeves in your setup – the cumulative effect becomes significant. The blue anodised finish isn't merely cosmetic; the anodisation process creates a hard, protective oxide layer that resists corrosion and wear far more effectively than bare aluminium. This means your investment in these Factory Team components will maintain its performance characteristics and appearance through countless running sessions, whether you're racing in dry heat, damp British conditions, or muddy off-road environments. The engineering tolerances are precise, ensuring perfect fitment with existing RC8B4 and RC8T4 components without any binding or play in the drivetrain.

Frequently Asked Questions

• Will these axle sleeves fit my RC8B4 or RC8T4? — Yes, these Factory Team CVA axle sleeves are specifically designed for the RC8B4, RC8B4e, RC8T4, and RC8T4e models in both nitro and electric formats. They are direct replacements for the original steel sleeves (part number AS81548), so fitment is guaranteed.
• How much weight do these sleeves save? — Each sleeve saves approximately 1.8 grams compared to the stock steel version. Whilst this might seem small, the reduction in rotating mass has a measurable impact on acceleration, deceleration, and overall handling responsiveness – particularly important in competitive RC racing where every fraction of a second counts.
• Are these suitable for beginners? — These sleeves are designed as an upgrade component for owners of RC8B4 and RC8T4 vehicles, so you'll need an existing buggy or truck to install them into. However, installation itself is straightforward and doesn't require specialist tools or advanced mechanical skills. If you're new to RC and looking to upgrade your first vehicle, these are an excellent choice once you've mastered basic RC maintenance.
• How do Factory Team parts compare to standard OEM sleeves? — Factory Team parts are developed and tested by Team Associated's race engineering team specifically for performance and durability at the highest competitive levels. The quality control, material selection, and precision manufacturing all exceed standard OEM components. When you upgrade to Factory Team parts, you're essentially equipping your RC8B4 or RC8T4 with components used by professional racers.
• Will these sleeves improve my lap times? — By reducing unsprung weight in the drivetrain, these sleeves improve acceleration, handling responsiveness, and traction consistency. The practical performance gain depends on your driving skill and setup, but the lighter, stiffer characteristics will make your RC8B4 or RC8T4 feel noticeably more responsive – particularly on technical tracks or challenging terrain.
• Can I use these on both nitro and electric RC8 variants? — Yes, these sleeves are compatible with all RC8B4 and RC8T4 series vehicles, whether powered by nitro engines or brushless electric motors. The CVA drivetrain architecture is identical across both powertrains, so these sleeves work equally well on any variant.
