If you're looking to enhance your ready to run RC model with quality aftermarket parts, these aluminium caster blocks represent a significant step up from standard plastic components. The precision engineering and material quality ensure that your steering response remains sharp and consistent, even under the demands of competitive racing or aggressive off-road bashing.

Key Features

• 6061-T6 Aluminium Construction — Machined from aircraft-grade 6061-T6 aluminium alloy, these caster blocks deliver exceptional strength-to-weight ratio that's far superior to plastic alternatives, ensuring your RC car can handle aggressive driving without flex or deflection that compromises steering accuracy.
• Orange-Anodised Finish — The brilliant anodised coating provides both aesthetic appeal and functional protection, resisting corrosion and UV degradation while giving your RC machine a premium, high-tech appearance that stands out from standard parts.
• Left and Right Pair — This package includes both left and right caster blocks, providing a complete upgrade solution for your front suspension geometry without requiring multiple purchases.
• Increased Steering Precision — By replacing flexible plastic components with rigid aluminium blocks, you'll experience noticeably improved steering response and consistency, giving you better control during high-speed cornering and technical manoeuvres.
• Enhanced Durability — Heavy-duty aluminium construction resists impacts, crashes, and the general wear that plastic parts suffer, meaning your caster blocks will maintain their performance characteristics through extended use and demanding conditions.
• Trail-Tuned Geometry Preservation — These blocks maintain your RC car's original suspension and steering geometry, ensuring that factory-tuned handling characteristics are preserved while gaining the material advantages of aluminium construction.
• Includes New Kingpins — The package includes new kingpins specifically designed for proper fitment with aluminium caster blocks, ensuring smooth operation and correct suspension geometry throughout your RC car's range of motion.

Technical Performance

The Traxxas Caster blocks TRX9733-ORNG represent a significant engineering upgrade for RC enthusiasts throughout the UK seeking to enhance their vehicles' front-end performance. Crafted from 6061-T6 aluminium, one of the most trusted materials in aerospace and automotive applications, these blocks deliver exceptional rigidity compared to standard plastic components. This material choice directly impacts steering response—the stiffer construction eliminates the deflection and flex that reduces precision in plastic parts, allowing you to maintain sharper, more predictable steering inputs throughout acceleration, braking, and cornering sequences. The precision machining process ensures that left and right blocks are perfectly matched, maintaining proper suspension geometry and eliminating the binding or uneven wear that can result from poorly toleranced parts. The anodised finish protects the aluminium from oxidation and corrosion, which is particularly important in the damp UK climate where RC cars are frequently exposed to wet conditions. These blocks integrate seamlessly with your existing RC suspension without requiring modification to other components, making them an ideal choice for those wanting a straightforward upgrade path. The included kingpins are specifically engineered for proper fitment and smooth operation throughout the full range of suspension travel, ensuring consistent performance whether you're running on tarmac tracks, natural terrain, or indoor carpet racing surfaces. The weight characteristics of 6061-T6 aluminium provide a slight increase in rotating mass compared to plastic, which can actually improve stability during aggressive driving while the rigid construction reduces energy loss that would otherwise be absorbed by flex in inferior materials.

Compatibility and Installation

These Traxxas caster blocks are designed to fit 2WD Slash, Stampede, Rustler, and other compatible 2WD Traxxas models. If you own a Bandit or Drag Slash, you'll need to install optional Heavy Duty front arms (available in multiple colours including black, red, orange, green, and blue) to provide the clearance required for full suspension and steering travel with the aluminium blocks. The stock arms on Bandit and Drag Slash models lack sufficient clearance due to their unique front suspension design, but this is easily rectified with the Heavy Duty upgrade arms, which are priced well under £15. The stock arms will still accept other aluminium upgrades including Big Bore shocks and aluminium steering blocks, but the Heavy Duty arms are specifically required for caster block fitment. Installation is straightforward—simply disassemble your existing plastic caster blocks, remove the old kingpins, and reassemble using the new aluminium blocks and included kingpins. Detailed exploded views are available from Traxxas to guide you through the process, and the entire installation typically takes just 15-20 minutes using basic RC tools.

Frequently Asked Questions

• What models do these Traxxas caster blocks fit? — These 6061-T6 aluminium caster blocks are designed for 2WD Traxxas models including Slash, Stampede, and Rustler. They will also fit Bandit and Drag Slash models if you first install the optional Heavy Duty front arms, which provide the necessary clearance for the larger aluminium blocks to operate through their full suspension and steering travel range.
• Will these caster blocks improve my RC car's steering? — Yes, significantly. By replacing flexible plastic components with rigid 6061-T6 aluminium, you'll experience improved steering precision and consistency. The stiffer material reduces deflection and flex that compromises steering response, giving you sharper, more predictable handling during cornering and high-speed driving.
• Are these caster blocks suitable for beginners? — These are suitable for any RC enthusiast, from beginners to advanced racers. Installation is straightforward—you're simply replacing existing plastic parts with their aluminium equivalents. The improvement in steering feel will benefit drivers at all skill levels, making them a worthwhile upgrade for any serious RC basher or racer.
• What colour options are available? — These caster blocks are available in multiple anodised colours including blue, orange, red, green, and pink, allowing you to coordinate with your RC car's colour scheme or personalise your machine's appearance.
• Do I need any special tools to install these? — No, installation requires only basic RC tools that you likely already have. You'll need a hex wrench or similar tool to remove the old blocks and install the new ones. The process is straightforward enough that most RC enthusiasts can complete it in 15-20 minutes.
• Will these caster blocks work with my upgraded suspension? — Yes, these aluminium caster blocks are compatible with other suspension upgrades including Big Bore shocks and aluminium steering blocks. In fact, combining multiple aluminium upgrades on the front end creates a comprehensive durability and performance enhancement that many serious RC enthusiasts pursue.
• How long do anodised aluminium caster blocks last? — When properly maintained, 6061-T6 aluminium caster blocks will outlast multiple plastic equivalents. The anodised finish protects against corrosion and UV damage, and the material itself resists impact damage far better than plastic.
