Traxxas Caster blocks, 6061-T6 aluminium (green-anodised), left & right, 4x22mm pin (4), 3x10mm BCS (with threadlock) (4), retainers (4) TRX10232-GRN

Overview

Upgrade your RC car's durability and performance with the Traxxas 6061-T6 aluminium caster blocks in eye-catching green anodised finish. These precision-engineered C-hubs represent a significant step up from standard plastic components, delivering the toughness and reliability that serious RC enthusiasts demand. Whether you're bashing on weekends or pushing your RC vehicle to its limits, aluminium caster blocks are among the most important durability upgrades available for compatible Traxxas models in the UK RC market.

The caster blocks are carefully machined from solid 6061-T6 aluminium alloy, a material renowned in engineering for its excellent strength-to-weight ratio and superior durability compared to plastic alternatives. The brilliant green anodised finish doesn't just look fantastic—it provides a protective oxide layer that resists corrosion and wear, ensuring your upgrade maintains its appearance and structural integrity through countless hours of driving. If you own a Traxxas Maxx or MaxxSlash short course truck, these aluminium caster blocks are the perfect investment in your vehicle's longevity.

This is an accessory part that transforms your RC vehicle's front suspension geometry while preserving the precise steering and suspension characteristics that make Traxxas vehicles renowned for their handling. The engineering excellence that Traxxas is recognised for worldwide is evident in every detail of these components. For bashers, racers, and RC enthusiasts across the UK seeking maximum durability without compromise, aluminium caster blocks represent outstanding value.

Key Features

• 6061-T6 Aluminium Construction — Machined from premium grade 6061-T6 aluminium alloy, these caster blocks offer dramatically superior strength and durability compared to stock plastic alternatives, ensuring they can withstand aggressive driving, high-speed impacts, and continuous use without cracking or deforming.
• Precision Machining from Solid Blocks — Each caster block is carefully machined from a solid block of aluminium rather than moulded or stamped, which preserves the exact steering and suspension geometry that Traxxas engineers designed into your vehicle, maintaining perfect handling characteristics.
• Green Anodised Finish — The brilliant green anodised coating provides both stunning visual appeal and practical protection, creating a hard oxide layer on the aluminium surface that resists corrosion, oxidation, and general wear from dirt, moisture, and UV exposure.
• Left and Right Configuration — This set includes both left and right caster blocks, providing complete front suspension coverage with matched geometry that ensures balanced handling and predictable steering response in all conditions.
• Included Hardware Package — The kit comes with all necessary fastening components: four 4x22mm suspension pins for secure mounting, four 3x10mm ball cup screws with threadlock compound pre-applied to prevent loosening during vigorous driving, and four retainers to keep everything in place.
• Pre-Applied Threadlock — The 3x10mm ball cup screws come with threadlock already applied, eliminating the need to source additional threadlock compound and ensuring your hardware stays tight through every jump, landing, and corner.
• Compatibility with Multiple Models — These caster blocks are engineered to fit Traxxas Maxx and MaxxSlash vehicles, with the design philosophy drawn from successful applications on Slash, Rustler, and Stampede 2WD models.

Technical Performance

The 6061-T6 aluminium used in these caster blocks represents a significant engineering advantage over plastic components. 6061-T6 is a heat-treated aluminium alloy specifically selected in the RC industry for its exceptional combination of strength, machinability, and corrosion resistance. When machined from solid blocks rather than moulded, the material's internal grain structure is optimised, resulting in components that can absorb impact loads and flexing stresses without developing stress cracks or permanent deformation. The anodising process creates a hard, wear-resistant surface layer measured in micrometres thick—thin enough to preserve tight tolerances but thick enough to provide meaningful protection against abrasion and environmental corrosion. These caster blocks maintain the precise steering geometry that Traxxas designed into your vehicle's front suspension, which is critical for consistent handling during high-speed runs, aggressive cornering, and competition driving. The included hardware—specifically the 4x22mm suspension pins and 3x10mm ball cup screws with threadlock—has been engineered to work seamlessly with the aluminium blocks, ensuring that vibration and impact forces don't cause fasteners to loosen and components to develop unwanted movement that degrades handling.

Frequently Asked Questions

• Will aluminium caster blocks fit my Traxxas Bandit or Drag Slash? — The Bandit and Drag Slash feature unique front suspension arms with different clearance requirements compared to Slash, Rustler, and Stampede models. To run these aluminium caster blocks on a Bandit or Drag Slash, you'll need to first upgrade to the optional Heavy Duty front arms, which are available in multiple colours and cost well under £15. The Heavy Duty arms provide the additional suspension and steering travel clearance that the chunky aluminium blocks require.
• What vehicles are these caster blocks compatible with? — These Traxxas 6061-T6 aluminium caster blocks are engineered to fit Traxxas Maxx and MaxxSlash short course trucks. The design also successfully fits Slash, Rustler, and Stampede 2WD models if you own any of those vehicles.
• Are these blocks easy to install? — Installation is straightforward for anyone with basic RC mechanical knowledge. Simply disassemble your existing plastic caster blocks using standard RC tools, and reassemble using the aluminium blocks and provided hardware. If you're unsure about the process, you can reference the exploded view diagrams available for your specific vehicle model on the Traxxas support website, which clearly show how all components fit together.
• Why choose aluminium over plastic caster blocks? — Aluminium caster blocks deliver dramatically superior durability and longevity compared to standard plastic alternatives. Plastic blocks can crack or permanently deform under impact and stress, especially during aggressive bashing or high-speed driving. 6061-T6 aluminium is strong enough to absorb these forces without damage, meaning your caster blocks will last through years of use rather than requiring replacement after a few months of heavy driving.
• What is 6061-T6 aluminium? — 6061-T6 is a heat-treated aluminium alloy engineered specifically for applications requiring a balance of strength, corrosion resistance, and machinability. The T6 designation indicates that the material has been heat-treated (solution heat-treated and artificially aged) to achieve maximum strength and hardness properties. This material is widely used in aerospace, automotive, and high-performance RC applications where durability is paramount.
• What does anodising do? — Anodising is an electrochemical process that creates a hard, protective oxide layer on the aluminium surface. This layer resists corrosion from moisture and dirt, prevents oxidation that would otherwise dull the finish, and significantly reduces wear from abrasion and friction. The green colour is integral to the anodised finish rather than painted on, meaning it won't chip or peel with normal use.
• Why are the suspension pins and ball cup screws included? — Traxxas includes the correct fastening hardware with the caster blocks to ensure that you have everything needed for a complete installation. The 4x22mm suspension pins are engineered to work specifically with these aluminium blocks' geometry, and the 3x10mm ball cup screws with pre-applied threadlock have been selected for optimal clamping force and vibration resistance.
• Can I use my existing fasteners with the new aluminium blocks? — Whilst the fasteners from your original plastic blocks may physically fit the aluminium blocks, Traxxas has designed the included hardware specifically for these components. Using the provided pins and screws ensures optimal performance and fitment. If you choose to reuse existing fasteners, we recommend applying fresh threadlock compound to ensure they remain secure.
