If you own a Traxxas Ford Fiesta ST Rally VXL, Rustler Ultimate VXL 4x4, Slash Ultimate 4x4 VXL, or any compatible Traxxas model, these caster blocks are a proven way to take your RC driving experience to the next level. The precision machining and premium 6061-T6 aluminium construction mean you're investing in parts that will last, perform reliably, and give you the control you need whether you're racing competitively or enjoying casual bashing sessions across the UK.

Key Features

• 6061-T6 Aluminium Construction — These caster blocks are precision-machined from billet 6061-T6 aluminium, which is one of the strongest and most reliable aluminium alloys available for RC applications. This material choice provides superior strength and precision compared to plastic alternatives, ensuring your RC car maintains accurate geometry and handling characteristics even under demanding driving conditions.
• Left and Right Pair — The package includes both left and right caster blocks, meaning you have everything needed to upgrade both sides of your RC vehicle's front suspension geometry. This is a complete pair designed to work together for balanced, symmetrical performance across your RC truck or buggy.
• Green Anodised Finish — The brilliant anodised finish serves a dual purpose: it provides a vibrant, eye-catching colour that makes your RC car stand out, while also delivering a protective coating that resists oxidation, corrosion, and wear during regular use. This durable finish maintains its appearance through countless hours of RC driving.
• Laser-Etched TRX Logo — Each block features a high-contrast laser-etched Traxxas TRX logo, adding an authentic touch of branding whilst demonstrating the premium quality of these components. This detail work shows the precision engineering that goes into every aspect of these caster blocks.
• Precision-Machined Design — Rather than being cast or moulded, these caster blocks are carefully machined from solid aluminium, ensuring tight tolerances and perfect geometry. This precision manufacturing means your RC vehicle will maintain consistent handling and control characteristics, critical for both competitive racing and recreational bashing.
• Multi-Model Compatibility — These caster blocks are compatible with numerous Traxxas models including the Ford Fiesta ST Rally VXL in green, orange, and red variants, the Rustler Ultimate VXL 4x4 brushless in green and blue, and the Slash VXL range in multiple colours. This broad compatibility makes them an excellent choice if you own any of these popular RC vehicles.

Technical Performance

The Traxxas Caster Blocks represent a significant engineering upgrade for RC enthusiasts in the UK seeking improved performance and durability. Manufactured from 6061-T6 aluminium, this aerospace-grade alloy is renowned for its excellent strength-to-weight ratio, making it ideal for high-performance RC applications. The material's properties allow for precision machining that creates perfectly accurate mounting surfaces, maintaining your RC vehicle's front-end geometry with exceptional consistency. This matters because caster angle directly affects how your RC car handles—too little caster and your vehicle feels loose and unpredictable; too much and it becomes sluggish in corners. By using precision-machined aluminium caster blocks, you're ensuring that your geometry remains stable and true, shot after shot, lap after lap. The green anodised finish applied to these blocks isn't merely cosmetic; anodising is an electrochemical process that creates a protective oxide layer on the aluminium surface. This layer provides genuine corrosion resistance and durability, essential for RC vehicles that may encounter dirt, moisture, and the demanding conditions typical of UK outdoor RC racing and bashing. Whether you're running your brushless RC truck on rough terrain or fine-tuning your rally car for competitive events, these caster blocks will maintain their integrity and performance characteristics, ensuring your vehicle handles predictably and responsively every time you take it out.

Frequently Asked Questions

• What are caster blocks and why do I need to upgrade to aluminium ones? — Caster blocks, also called C-hubs, are the components that hold your RC vehicle's front wheels and connect them to the suspension. The caster angle (tilt of the steering axis) affects handling, steering response, and overall vehicle control. Standard plastic caster blocks can flex and wear under stress, changing your vehicle's geometry and making handling inconsistent. Upgrading to precision-machined 6061-T6 aluminium caster blocks ensures rigid, accurate geometry that doesn't flex or wear, giving you predictable handling and superior control in all conditions.
• Which Traxxas models are compatible with the TRX6832G caster blocks? — These caster blocks are designed for Traxxas X-Series vehicles and are compatible with the Ford Fiesta ST Rally VXL (green, orange, and red), Ford Fiesta ST Rally BL-2S (red), Rustler Ultimate VXL 4x4 (green and blue), Slash Ultimate 4x4 VXL (orange), and Slash VXL (blue, green, orange, and red). Before purchasing, verify your specific model number to ensure compatibility.
• Do these caster blocks make a real difference to performance? — Yes, genuinely. By eliminating the flex found in plastic components, these aluminium caster blocks maintain precise front-end geometry, which directly improves steering response, cornering stability, and overall handling consistency. You'll notice improved predictability, especially when pushing your RC vehicle to its limits on the track or across challenging terrain.
• Are the caster blocks difficult to install? — Installation difficulty depends on your mechanical experience and familiarity with your specific Traxxas model. The blocks bolt onto your existing suspension components, so you'll need basic tools and mechanical knowledge. We recommend consulting your vehicle's manual or watching tutorial videos for your specific model before attempting installation. If you're unsure, our team at RC Model Shop can offer guidance.
• What makes 6061-T6 aluminium special for RC vehicles? — 6061-T6 is an aluminium alloy heat-treated to T6 specification, meaning it has been solution heat-treated and artificially aged to achieve optimal strength. This grade is lighter than steel but significantly stronger than standard aluminium, making it ideal for precision RC components. It machines beautifully to tight tolerances, resists corrosion well, and won't fatigue under the repeated stress of RC driving.
• How long will the anodised finish last? — The anodised finish is genuinely durable when properly maintained. Hard-anodised coatings like those on these Traxxas blocks can last years of regular use, though aggressive racing on abrasive surfaces may eventually wear through the coating. The underlying aluminium remains protected even if the anodising eventually shows wear marks. Avoiding harsh chemicals and rinsing with clean water after muddy runs helps preserve the finish.
