Traxxas Caster blocks (c-hubs), 6061-T6 aluminium (Blue-anodised), left & right / kingpin bushings (4 pcs) TRX9532X

Overview

The Traxxas Sledge Caster Blocks (C-Hubs) in blue-anodised 6061-T6 aluminium represent a premium upgrade for your Sledge 1/8 scale brushless electric monster truck. These precision-engineered caster blocks are designed to improve the appearance, ruggedness, and handling characteristics of your RC monster truck, making them an essential tune-up option for anyone serious about getting the best performance from their Sledge. Whether you're a competitive racer pushing your RC car to its limits or a weekend basher looking to enhance your truck's durability and aesthetics, these aluminium c-hubs deliver professional-grade quality that Traxxas is renowned for across the RC hobby community in the UK and beyond.

Caster blocks, also known as c-hubs, are critical suspension components that connect your truck's steering system to the front wheels. Upgrading from standard plastic parts to these billet aluminium caster blocks significantly enhances steering precision, reduces flex, and improves the overall control of your RC car during high-speed runs and aggressive cornering. The blue-anodised finish isn't just about looks—it's a protective coating that adds durability while giving your Sledge a striking, professional appearance that stands out on the track or trail. For UK RC enthusiasts looking to optimise their Sledge setup, these caster blocks offer the perfect balance of performance enhancement and visual upgrade.

This is a genuine Traxxas part designed specifically for the Sledge Belted 1/8 4WD brushless electric monster truck, ensuring perfect fitment and compatibility. The included kingpin bushings and mounting hardware make installation straightforward, allowing you to upgrade your RC monster truck quickly and get back to enjoying improved handling and control. These caster blocks are a trusted choice among experienced RC car builders and tuners who understand that quality suspension components are fundamental to achieving consistent performance.

Key Features

• 6061-T6 Billet Aluminium Construction — The use of premium grade 6061-T6 aluminium provides superior strength and rigidity compared to standard plastic caster blocks, reducing flex and twisting during hard cornering and aggressive driving, which directly translates to more predictable and responsive steering behaviour in your RC monster truck.
• Blue-Anodised Finish — The brilliantly-anodised blue coating serves multiple purposes: it protects the aluminium from corrosion and wear, provides a vibrant colour that enhances the visual appeal of your Sledge, and features a high-contrast laser-etched TRX logo that adds a professional, branded touch to your build.
• Left and Right Caster Blocks — This package includes both left and right c-hubs, meaning you receive a complete pair that allows for symmetrical suspension geometry and balanced handling characteristics across both front wheels of your 1/8 scale RC truck.
• Precision Engineering — Traxxas billet caster blocks are manufactured to exacting tolerances, ensuring that strength and precision are delivered exactly where you need it most in your suspension geometry, resulting in improved durability and more consistent on-track performance.
• Included Kingpin Bushings (4 Pieces) — The package contains four kingpin bushings that facilitate smooth, wear-resistant rotation of the caster blocks around the kingpins, reducing friction and extending the lifespan of your suspension components while maintaining responsive steering feel.
• Complete Hardware Kit — Traxxas supplies four 3x20 mm screws with integrated threadlock, eliminating the need to source fasteners separately and ensuring your caster blocks remain securely fastened during intense driving sessions without risk of coming loose.

Technical Performance

These aluminium caster blocks represent a significant performance upgrade over plastic alternatives. The 6061-T6 aluminium material is chosen specifically for its excellent strength-to-weight ratio and superior rigidity, properties that are essential for maintaining precise steering geometry under the extreme forces generated during high-speed runs and aggressive cornering in RC monster truck racing. The billet construction process ensures consistent material quality throughout the component, eliminating the weak points that can develop in injection-moulded plastic parts. The anodised finish is not merely cosmetic—it provides a hard, protective oxide layer that resists corrosion, impact damage, and UV degradation, extending the operational life of these components significantly. For drivers of the Traxxas Sledge brushless 1/8 4WD monster truck, upgrading to these aluminium caster blocks will be immediately noticeable in terms of steering response, cornering stability, and overall vehicle control. The precision engineering ensures that suspension geometry remains consistent throughout hard driving, reducing the cumulative wear that degraded handling characteristics. The inclusion of quality kingpin bushings means reduced steering play and smoother suspension articulation, contributing to more predictable vehicle behaviour at speed. These components are engineered to work seamlessly with the Sledge's suspension geometry and weight distribution, making them a recognised upgrade choice among competitive RC truck drivers in the UK and internationally.

Frequently Asked Questions

• Will these caster blocks improve the handling of my Sledge RC monster truck? — Yes, absolutely. The rigid 6061-T6 aluminium construction significantly reduces flex compared to plastic caster blocks, resulting in more responsive steering, improved cornering stability, and more predictable handling characteristics—benefits that are particularly noticeable at speed and during aggressive driving.
• Are these caster blocks difficult to install on my RC car? — No, installation is straightforward for anyone with basic RC tuning knowledge. The package includes all necessary hardware (the kingpin bushings and mounting screws with threadlock), and the parts are designed to drop into place on your Sledge with no modifications required. If you're new to RC car maintenance, plenty of online guides and YouTube tutorials demonstrate the installation process.
• What is the difference between plastic and aluminium caster blocks? — Aluminium caster blocks like these offer several advantages: they are significantly stronger and more rigid, reducing flex under load; they provide superior durability and resistance to impact damage; they maintain more consistent suspension geometry under stress; and they offer a professional appearance with the anodised finish. Plastic caster blocks are lighter and less expensive, but they flex and wear more quickly, particularly during competitive or aggressive driving.
• Do I need any tools to install these caster blocks? — Installation requires only basic RC tools—typically a small hex key or screwdriver to remove your existing plastic caster blocks and install the new aluminium ones using the supplied screws. Threadlock is already integrated into the fasteners, so you won't need to apply additional loctite.
• Will these work with my Sledge in any colour? — Yes, these blue-anodised caster blocks are compatible with all colour variants of the Traxxas Sledge monster truck (green, red, blue, and orange). The blue finish will complement any Sledge colour while adding visual contrast and a premium appearance to your build.
• Are these genuine Traxxas parts? — Yes, when purchased from RC Model Shop, you are receiving authentic Traxxas parts manufactured to the company's exacting specifications. The part number TRX9532X is the official Traxxas designation for these components.
