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

Overview

The Traxxas Caster blocks, 6061-T6 aluminium (blue-anodised), left & right represent a premium upgrade for your high-performance RC short course truck or monster truck. Whether you're a seasoned RC enthusiast running a Traxxas Maxx, Maxx Slash, or WideMaxx, or you're looking to enhance your RC car UK setup with genuine OEM parts, these aluminium C-hubs deliver the precision steering geometry and durability that competitive RC racing demands. These caster blocks are engineered to take your RC vehicle's handling to the next level whilst maintaining the reliability that Traxxas is recognised for worldwide.

If you've ever felt limited by plastic suspension components or experienced flex under aggressive cornering, upgrading to aluminium caster blocks is one of the most effective suspension tuning modifications you can make. The Traxxas 6061-T6 aluminium construction transforms the C-hub design from a proven baseline into a genuinely toughened component that resists the flex and wear that comes with serious RC bashing or competition driving. These aren't just stronger—they're engineered to preserve the exact steering and suspension geometry that Traxxas designed into your vehicle, ensuring predictable handling characteristics whether you're on the track or bashing through rough terrain.

The brilliant blue-anodised finish isn't just about aesthetics, though it certainly adds high-tech style to your machine. The anodising process creates a protective oxide layer that shields the aluminium from corrosion, oxidation, and the general wear and tear of outdoor RC use. This means your investment will maintain its appearance and performance integrity for seasons to come, making these caster blocks an excellent choice for UK RC enthusiasts who want reliability and style combined in one upgrade package.

Key Features

• 6061-T6 Aluminium Construction — The caster blocks are machined from aerospace-grade 6061-T6 aluminium, which offers exceptional strength-to-weight ratio and superior rigidity compared to plastic alternatives, ensuring your RC vehicle maintains precise steering geometry under load and during aggressive cornering.
• Precision CNC Machining — Each caster block is carefully machined from a solid block of aluminium to preserve the original steering and suspension geometry that Traxxas engineered into your vehicle, guaranteeing that handling characteristics remain true and predictable even under extreme driving conditions.
• Blue-Anodised Finish — The durable anodised coating provides both aesthetic appeal and functional protection, creating a corrosion-resistant surface that maintains its brilliant appearance through countless bashing sessions and outdoor use in UK weather conditions.
• Left and Right Pair — The kit includes both left and right caster blocks, allowing you to upgrade your entire front suspension geometry for balanced, consistent handling across both sides of your RC vehicle.
• Complete Hardware Included — Everything you need for installation is provided in the box, including suspension pins, ball cup screws with threadlock, and retainers, eliminating the need to source additional fasteners and ensuring proper assembly with pre-applied threadlock for secure connections.
• Enhanced Durability — Upgrade your RC car's toughness and durability significantly compared to standard plastic C-hubs, making these blocks ideal for serious bashers, competitive racers, and anyone who demands reliability from their RC equipment.

Technical Performance

These Traxxas caster blocks represent a significant performance upgrade in the suspension geometry department. The 6061-T6 aluminium material is the same aerospace-grade alloy used in professional RC racing components and aircraft structures, offering exceptional rigidity and fatigue resistance. When you upgrade from plastic to aluminium caster blocks, you're eliminating flex in the C-hub assembly—this is critical because any flex in the steering geometry translates directly to inconsistent handling, unpredictable cornering behaviour, and reduced steering responsiveness. The precision CNC machining process preserves Traxxas's original suspension and steering geometry perfectly, ensuring that your RC vehicle handles exactly as the engineers intended, with no geometry changes or handling surprises. The blue-anodised finish provides more than just visual appeal; the anodising process creates a hard, protective oxide layer that prevents the raw aluminium from oxidising or corroding, which is particularly important for UK RC enthusiasts who regularly encounter moisture and variable weather conditions. These blocks are specifically engineered as direct replacements for the plastic versions, making them bolt-in upgrades that require no modification to your existing Traxxas short course truck or monster truck. The included 4x22mm suspension pins provide the precise pivot points for your steering linkage, whilst the 3x10mm ball cup screws with threadlock ensure secure fastening that won't work loose during high-speed running or aggressive RC driving.

Frequently Asked Questions

• Why should I upgrade from plastic to aluminium caster blocks on my RC truck? — Plastic caster blocks flex under cornering forces and hard landings, which causes your steering geometry to change unpredictably during driving. Upgrading to these 6061-T6 aluminium blocks eliminates flex entirely, maintaining precise steering geometry at all times. This results in more predictable handling, better cornering performance, improved consistency lap-to-lap, and dramatically increased durability. Serious RC enthusiasts, whether they're competitive racers or dedicated bashers, choose aluminium C-hubs as one of the first suspension upgrades for exactly these reasons.
• Are these caster blocks difficult to install on my RC car? — No, these are direct replacement parts that bolt straight into your existing Traxxas short course truck or monster truck chassis. The installation process is straightforward—you'll remove the old plastic caster blocks and install the new aluminium ones using the included suspension pins, ball cup screws, and retainers. All fasteners are included, and the pre-applied threadlock on the ball cup screws ensures your installation stays secure during aggressive RC driving.
• Will these caster blocks fit my Traxxas RC vehicle? — Yes, these blocks are designed as genuine Traxxas upgrade parts and are confirmed compatible with the Traxxas Maxx Slash 1/8 4WD 6S Brushless Short Course Truck (all colour variants) and the Traxxas WideMaxx Monster Truck (all colour variants). If you own any of these models, these blocks are a direct fit. Check your vehicle's model number against the compatibility list to confirm fitment.
• How do the blue-anodised blocks compare to other anodised finishes? — The blue-anodised finish provides both aesthetic customisation and functional protection. The anodising process creates a hard oxide layer that resists corrosion, oxidation, and wear from outdoor use in UK weather conditions. Unlike raw aluminium, which oxidises over time and loses its shine, the anodised finish maintains its appearance and protective properties through countless RC sessions. The brilliant blue colour also matches perfectly with blue Traxxas vehicles or complements other colour schemes for a professional appearance.
• What is included with these caster blocks, and do I need to buy anything else? — The package includes both left and right caster blocks, 4x22mm suspension pins, 3x10mm ball cup screws with threadlock already applied, and retainers. Everything required for complete installation is included—you won't need to source additional fasteners. All you'll need is a basic RC tool set and approximately 15-20 minutes to complete the upgrade.
• Are these genuine Traxxas parts? — Yes, these are authentic Traxxas OEM (Original Equipment Manufacturer) parts manufactured to the exact specifications that Traxxas uses in their factory vehicles. You're purchasing genuine products with Traxxas quality assurance behind them.
