TRX10733-GRN

Overview

The Traxxas Caster blocks (C-hubs), 6061-T6 aluminium (Green-anodised) (left & right) TRX10733-GRN are premium replacement suspension components designed to elevate the performance and aesthetics of your Mini Maxx RC monster truck. Whether you're a dedicated RC enthusiast in the UK looking to upgrade your existing vehicle or a competitive racer seeking to improve handling precision, these aluminium caster blocks deliver measurable improvements in durability, steering geometry and visual appeal. Traxxas has engineered these components to be an essential upgrade for anyone serious about getting the best from their Mini Maxx platform.

Built from aircraft-grade 6061-T6 aluminium, these caster blocks represent a significant upgrade over standard plastic alternatives. The material choice is not arbitrary—6061-T6 aluminium is renowned in engineering circles for its exceptional strength-to-weight ratio, corrosion resistance and machinability, making it an ideal choice for precision RC suspension components. The brilliant green anodised finish doesn't just look stunning on your RC car UK; the anodising process actually hardens the surface and provides additional protection against wear and oxidation during repeated use in demanding conditions.

What sets these caster blocks apart is Traxxas's meticulous manufacturing process. Each hub is carefully machined from a solid block of aluminium rather than cast or stamped, preserving critical steering and suspension geometry that directly impacts how your Mini Maxx handles on the track or bash course. This precision engineering ensures that every component maintains exact tolerances, translating to more predictable cornering, improved weight transfer and ultimately faster lap times or more responsive control during freestyle driving sessions.

Key Features

• 6061-T6 Aluminium Construction — These caster blocks are machined from high-grade 6061-T6 aluminium, a material specification that guarantees superior strength compared to plastic alternatives whilst maintaining a lightweight profile that doesn't compromise your Mini Maxx's performance characteristics or acceleration.
• Brilliant Green Anodised Finish — The eye-catching green anodised coating serves dual purposes: it delivers striking visual customisation that makes your RC monster truck stand out, whilst the anodising process itself creates a hard oxide layer that resists corrosion, scuffing and UV fading during extended outdoor use.
• Precision Machined Geometry — Each caster block is carefully machined from a complete aluminium billet, not cast or formed, ensuring that steering angles, suspension pick-up points and camber geometry are preserved to factory specifications, delivering consistent handling performance across multiple driving sessions.
• Left and Right Pair Included — You receive matched left and right caster blocks in this package, providing complete front suspension coverage for your Mini Maxx so you can upgrade both sides simultaneously for balanced handling characteristics.
• Improves Appearance and Control — Beyond the functional benefits of improved steering precision and suspension performance, the aluminium construction and vibrant green finish significantly enhance your RC car's aesthetic appeal, creating a more premium and professional appearance.
• Factory Fit and Finish Guarantee — As genuine Traxxas accessories manufactured by Traxxas specifically for Traxxas vehicles, these caster blocks deliver perfect factory-spec fitment without requiring modification, ensuring seamless installation and reliable performance from day one.
• Increased Durability and Ruggedness — Aluminium's superior hardness compared to plastic means these caster blocks withstand repeated impacts, aggressive driving, track collisions and outdoor use far better than stock components, extending service life and reducing the frequency of replacement.
• Complete Hardware Package — The caster blocks come with all necessary installation hardware including suspension pins and mounting screws, eliminating the need to source additional fasteners or components to complete your upgrade.

Technical Performance

These caster blocks represent a substantial materials upgrade over standard plastic C-hubs found on many ready-to-run RC models. The 6061-T6 aluminium alloy used in their construction offers approximately three times the tensile strength of acetal plastic whilst remaining significantly lighter than alternatives like steel or titanium, making it the optimal choice for high-performance RC suspension applications. The precision machining process employed by Traxxas ensures that steering geometry, suspension angles and geometry tolerances are maintained to exacting standards, directly impacting your Mini Maxx's handling balance, turn-in response and overall directional stability. The green anodised finish isn't merely cosmetic—the Type II or Type III anodising process creates a protective oxide layer typically 0.0002 to 0.0005 inches thick that prevents corrosion, reduces friction between moving parts and resists the degradation that exposure to UV light, moisture and salt (from outdoor or wet conditions) can cause to bare aluminium. When installed on your Mini Maxx, these upgraded caster blocks work in conjunction with your existing suspension system to deliver more responsive cornering, improved weight transfer during acceleration and braking, and enhanced predictability during both on-road and off-road driving. The engineering philosophy behind these components is straightforward: by eliminating flex and compliance in the suspension arm mounts, you achieve more direct transmission of driver inputs to wheel positioning, which translates to faster reaction times, more precise control and ultimately improved performance whether you're chasing competitive lap times or enjoying recreational bashing.

Frequently Asked Questions

• Are these caster blocks compatible with my Mini Maxx RC monster truck? — Yes, these Traxxas TRX10733-GRN caster blocks are specifically engineered for Mini Maxx models, including the Mini Maxx BL-2S (available in blue, green, orange and black variants), Mini Rally VXL Ford RS200 (red, blue and grey options), and Mini Slash BL-2S 4X4 RTR Short Course Truck (pink, green, yellow and orange colours). As genuine Traxxas accessories manufactured by Traxxas for Traxxas vehicles, they guarantee perfect factory fit every time without modification.
• What is the difference between plastic and aluminium caster blocks? — Aluminium caster blocks like these offer significantly greater strength, stiffness and durability compared to plastic alternatives. Whilst plastic components can flex under load, potentially affecting suspension geometry and handling consistency, 6061-T6 aluminium maintains rigid geometry even during aggressive driving or impact events. Aluminium also resists UV degradation, won't crack from temperature fluctuations, and maintains dimensional stability far longer than plastic, making them a worthwhile upgrade for serious RC drivers and those who bash their vehicles frequently.
• Do I need any special tools to install these caster blocks? — Installation of these caster blocks requires basic RC model tools including a small Allen key for screw removal and assembly. The package includes all necessary fasteners (suspension pins, screws and retainers), so you won't need to source additional hardware. Most RC hobbyists comfortable performing basic maintenance on their ready-to-run RC vehicles will find installation straightforward, though consulting your Mini Maxx manual for specific torque specifications is recommended.
• Will upgrading to aluminium caster blocks improve my lap times? — Yes, upgrading to precision-machined aluminium caster blocks can deliver measurable performance improvements. By eliminating flex in the suspension arm mounts and maintaining exact steering and camber geometry, these components provide more direct, responsive handling characteristics that allow drivers to carry speed more confidently through corners, improve brake and acceleration feel, and achieve more consistent lap times. Competitive RC drivers frequently upgrade to aluminium suspension components as part of their performance optimisation strategy.
• Are the green anodised caster blocks available in other colours? — Yes, Traxxas offers these caster blocks in multiple anodised finishes to suit different Mini Maxx colour schemes and personal preferences. Grey anodised (TRX10733-GRAY) and blue anodised (TRX10733-BLUE) variants are available, allowing you to match your caster blocks to your vehicle's overall aesthetic or create contrasting colour combinations for visual impact.
• How long do aluminium caster blocks typically last? — With proper maintenance and reasonable care, 6061-T6 aluminium caster blocks will provide years of reliable service. The material resists fatigue cracking, won't degrade from UV exposure like plastic, and the anodised finish protects against corrosion. Replacement is typically driven by major impacts or collision damage rather than material degradation, making them a sound long-term investment for your RC hobby.
