Traxxas Extreme Heavy Duty Caster Blocks Black Left Right 2WD TRX9135

Overview

The Traxxas Caster Blocks (C-Hubs) Extreme Heavy Duty in Black represent a significant upgrade for RC enthusiasts running 2WD Traxxas vehicles. These replacement left and right caster blocks are engineered to withstand the demands of aggressive driving, whether you're a serious basher or competitive racer in the UK RC scene. Built with extra material throughout their construction, these extreme heavy-duty components deliver enhanced strength and durability compared to standard parts, making them an essential upgrade for anyone looking to extend the lifespan of their RC car UK and improve overall reliability during intense driving sessions.

If you're piloting a Traxxas Bandit, Drag Slash, or one of the compatible model variants, you'll appreciate how these heavy-duty caster blocks maintain structural integrity under extreme stress and repetitive impacts. The beefed-up design means fewer broken parts during high-speed runs, backflips, and hard landings. For UK-based RC drivers who demand performance and durability from their ready to run RC cars and upgrade components, these caster blocks represent a worthwhile investment that will keep your vehicle running at peak performance.

Designed as standard replacement parts for the 9180 and 9181-series 2WD Extreme Heavy-Duty Upgrade Kits, these caster blocks are also fully compatible with non-EHD (Extreme Heavy Duty) parts and genuine Traxxas aluminium accessories, giving you complete flexibility when building your perfect RC setup. Whether you're running a modified street basher, a backyard stunter, or preparing for competitive racing events, upgrading to these extreme heavy-duty caster blocks is a practical and sensible choice for long-term reliability.

Key Features

• Extreme Heavy-Duty Construction — These caster blocks are manufactured with significantly increased material throughout their design, creating a much stronger and more durable component that can absorb impacts and lateral forces that would crack or break standard plastic parts. This reinforced engineering ensures your RC car UK maintains structural integrity through demanding driving sessions.
• Left and Right Pair Included — You receive both the left and right caster blocks in this single package, providing everything needed to perform a complete front-end upgrade on your compatible Traxxas 2WD vehicle without purchasing separate left and right components.
• Compatible with Multiple Upgrade Kits — These blocks are specifically designed as standard replacements for 9180 and 9181-series 2WD Extreme Heavy-Duty Upgrade Kits, making them the perfect choice if you're already running one of these systems or planning to upgrade your vehicle with genuine Traxxas performance parts.
• Works with Non-EHD Parts — The versatile design means you can mix and match these extreme heavy-duty caster blocks with your existing non-EHD components and other Traxxas parts, giving you flexibility in how you build and configure your RC setup without requiring a complete replacement of all suspension elements.
• Aluminium Accessory Compatible — These caster blocks work seamlessly with genuine Traxxas aluminium accessories, allowing you to upgrade your suspension and steering geometry with aftermarket components whilst maintaining full compatibility and structural reliability.
• Complete Hardware Package — The kit includes two 3x26mm hinge pins and two 3x15mm ball cup screws (BCS), providing all the fastening hardware needed to install these caster blocks on your vehicle without hunting for additional parts or making repeat trips to your local RC shop.

Technical Performance

The Traxxas Extreme Heavy-Duty Caster Blocks represent a significant engineering upgrade over standard components, with reinforced plastic construction designed to withstand the punishment of aggressive RC driving. The enhanced material thickness throughout the caster block structure means improved rigidity and reduced flex during high-speed cornering, acceleration, and braking events. The included hardware — specifically the 3x26mm hinge pins (two pieces) and 3x15mm ball cup screws (two pieces) — ensures proper alignment and smooth articulation of the steering geometry. These components work in harmony with your vehicle's suspension system to maintain predictable steering response and precise control throughout the range of driving conditions you'll encounter. The compatibility with both extreme heavy-duty upgrade kits and standard Traxxas components demonstrates the thoughtful engineering that goes into Traxxas products, allowing owners to upgrade strategically rather than replacing entire systems at once. For UK-based RC enthusiasts running 2WD platforms, these caster blocks are manufactured to the same exacting standards as all Traxxas replacement parts, ensuring consistent performance and reliability whether you're driving on tarmac, dirt, carpet, or mixed terrain.

Frequently Asked Questions

• Which Traxxas vehicles are compatible with these extreme heavy-duty caster blocks? — These replacement caster blocks are designed for use with Traxxas Bandit, Drag Slash (including the 1967 Chevrolet C10 Truck variant and Ford Mustang 5.0 variants), and other compatible 2WD models. They are standard replacement parts for 9180 and 9181-series 2WD Extreme Heavy-Duty Upgrade Kits, though they also work with non-EHD components, giving you flexibility in how you configure your vehicle.
• Do I need any additional parts to install these caster blocks? — No, this package includes everything you need for installation. The kit comes complete with the left and right caster blocks plus all required fastening hardware: the 3x26mm hinge pins and 3x15mm ball cup screws. You won't need to source additional components from your local RC shop UK.
• What's the main advantage of upgrading to extreme heavy-duty caster blocks? — The extreme heavy-duty design features extra material throughout the caster block structure, creating a much stronger component that resists cracking and breaking during aggressive driving, jumps, and hard impacts. If you're an aggressive driver or basher who regularly puts your RC car UK through demanding conditions, this upgrade will significantly reduce parts breakage and improve overall reliability.
• Can I use these heavy-duty caster blocks with my existing non-EHD parts? — Yes, these caster blocks are fully compatible with non-EHD (non-Extreme Heavy Duty) Traxxas parts as well as genuine Traxxas aluminium accessories, allowing you to upgrade selectively and build exactly the configuration you want without needing to replace all suspension components at once.
• Are these suitable for beginners? — These are replacement parts rather than a complete ready to run RC car, so they're designed for owners who already have a compatible Traxxas vehicle and want to upgrade specific components. If you're new to the hobby, you'll want to start with a ready to run RC package, and then add parts like these as you develop your skills and understanding of RC vehicle upgrades.
• What's included in the hardware? — The package includes two 3x26mm hinge pins, which are the primary pivot pins for steering articulation, and two 3x15mm ball cup screws (BCS), which secure the ball studs and maintain proper geometry.
