Overview

The Traxxas Caster Blocks (C-Hubs) in Dark Titanium-anodised 6061-T6 aluminium represent a significant upgrade for your Traxxas Sledge monster truck. These precision-engineered components are designed to enhance both the appearance and performance of your RC vehicle, making them an essential addition for anyone serious about improving their Sledge's handling, durability and visual appeal. Whether you're a dedicated weekend basher, a competitive racer, or an RC enthusiast looking to elevate your machine, these aluminium caster blocks deliver the strength and precision engineering that Traxxas is renowned for across the RC car UK market.

Traxxas has taken an already proven design and significantly enhanced it by machining these caster blocks from premium 6061-T6 aluminium billet. This material choice isn't arbitrary — it represents a fundamental upgrade over standard plastic alternatives, delivering superior strength, rigidity and longevity. The careful machining process preserves the critical steering and suspension geometry that's essential for maintaining your Sledge's handling characteristics whilst adding measurable durability improvements. The brilliantly-anodised Dark Titanium finish doesn't just look exceptional; it provides additional protection against corrosion and wear, ensuring these components maintain their appearance and functionality through countless hours of bashing, racing and off-road driving.

For UK RC enthusiasts running a Traxxas Sledge 1/8 scale brushless electric monster truck, these aluminium caster blocks represent one of the most impactful chassis upgrades available. They improve ruggedness across challenging terrain, enhance steering control and precision, and add genuine high-tech style to your machine. The laser-etched TRX® logo features a high-contrast design that catches light beautifully, transforming the appearance of your Sledge with vibrant colour coordination. These are genuine Traxxas accessory parts engineered to OEM specifications, ensuring perfect fitment and reliability.

Key Features

• 6061-T6 Aluminium Construction — The caster blocks are precision-machined from aerospace-grade 6061-T6 aluminium billet, which offers significantly greater strength and precision compared to plastic alternatives, delivering improved durability for intense off-road driving whilst maintaining critical suspension geometry.
• Dark Titanium-Anodised Finish — The brilliantly-anodised coating provides exceptional corrosion resistance, adds striking visual appeal to your Sledge, and ensures these components maintain their appearance through harsh weather, mud, water and repeated use across challenging terrain.
• Laser-Etched TRX® Logo — A high-contrast laser-etched logo provides distinctive branding and visual interest, demonstrating genuine Traxxas engineering and adding professional finishing touches to your RC machine's appearance.
• Left and Right Caster Blocks — This kit includes both left and right caster blocks, providing the complete pair needed for a full upgrade across your Sledge's front suspension, ensuring balanced handling and symmetrical performance.
• Improved Steering Control — The rigid aluminium construction eliminates flex and deflection present in plastic hubs, directly translating to more responsive steering, better wheel alignment maintenance, and enhanced precision during high-speed cornering and aggressive manoeuvres.
• Enhanced Ruggedness — Aluminium caster blocks provide substantially improved impact resistance compared to plastic alternatives, protecting critical suspension geometry when landing jumps, hitting rocks, or navigating rough terrain at speed.
• Precision Engineering — Careful machining from solid billet preserves exact steering and suspension geometry specifications, ensuring your Sledge maintains factory handling characteristics whilst gaining the durability benefits of aluminium construction.
• 4x Kingpin Bushings Included — The kit supplies four kingpin bushings that work with the caster blocks to provide smooth steering articulation and precise kingpin geometry for optimised handling.
• 3x20mm Screws with Threadlock — Four premium 3x20mm screws with integrated threadlock compound ensure secure, vibration-resistant fastening that won't loosen during intense driving sessions.

Technical Performance

These Traxxas Caster Blocks represent a fundamental engineering upgrade for the Sledge platform. The 6061-T6 aluminium construction delivers measurable performance benefits over standard plastic C-hubs through superior material properties. Aluminium provides significantly higher strength-to-weight ratio, greater rigidity to eliminate suspension flex, and improved impact resistance when landing jumps or hitting obstacles at speed. The billet machining process ensures micron-level precision, preserving the exact steering axis angles and kingpin geometry that Traxxas engineers specified for optimal Sledge handling. This precision is critical because even small deviations in suspension geometry can affect steering response, cornering grip and front-end stability.

The Dark Titanium-anodised finish adds a protective oxide layer that dramatically improves corrosion resistance compared to bare aluminium, extending component lifespan in wet conditions common to UK RC driving. The anodising process is carefully controlled to achieve a beautiful titanium grey colour that coordinates perfectly with the Sledge's design language. The included kingpin bushings (4 pcs) are essential wear items that provide smooth, controlled articulation of the steering column, allowing precise kingpin geometry maintenance. The 3x20mm screws with threadlock compound ensure vibration-resistant fastening, preventing the gradual loosening that can occur during aggressive driving. This attention to detail in both design and included hardware demonstrates Traxxas's commitment to quality in genuine replacement and upgrade parts for the RC car UK enthusiast.
