Traxxas Extreme Heavy-Duty Caster Blocks Left Right Blue TRX9136-BLUE

Overview

The Traxxas Caster blocks (c-hubs), extreme heavy duty, Blue (left & right) represent a premium upgrade solution for owners of 2WD Traxxas RC vehicles looking to maximise durability and performance. These replacement caster blocks are engineered from the ground up to withstand the most demanding driving conditions, whether you're a competitive racer pushing your RC car UK limits or a weekend basher enjoying high-speed runs across rough terrain. If you own a Rustler, Slash, Stampede, or Bigfoot model and have installed the #9180 or #9181 upgrade kit, these extreme heavy-duty caster blocks are the perfect companion to complete your suspension upgrade.

Caster blocks (also known as c-hubs) are critical suspension components that control the geometry and angle of your front wheels. They directly affect how your RC car handles, steers, and maintains traction during aggressive driving. By upgrading to these extreme heavy-duty versions, you're investing in parts that have been beefed up with extra material throughout their structure, dramatically increasing their strength and resistance to breakage. This is particularly important for serious RC enthusiasts who demand maximum durability from their equipment.

These blue caster blocks come as a matched left and right pair, ensuring symmetrical handling characteristics across both sides of your vehicle's front axle. They integrate seamlessly with both extreme heavy-duty and standard parts, and they're also fully compatible with Traxxas aluminium accessories, giving you complete flexibility in customising your RC vehicle's setup. Whether you're preparing for competition, upgrading your ready to run RC truck, or simply want to make your vehicle more resilient to crashes and impacts, these extreme heavy-duty caster blocks deliver the peace of mind that comes with running premium quality Traxxas components.

Key Features

• Extreme Heavy-Duty Construction — These caster blocks are manufactured with extra material throughout their design, creating a significantly stronger and more durable component than standard parts, making them ideal for aggressive driving styles and competitive use.
• Matched Left and Right Pair — You receive both the left and right caster blocks in a single package, ensuring perfectly matched geometry and symmetrical steering response across the front axle of your RC vehicle.
• Designed for 9180 and 9181 Upgrade Kits — These blocks are purpose-built as standard replacements for the #9180 and #9181-series 2WD Extreme Heavy-Duty Upgrade Kits, meaning they integrate perfectly with these proven upgrade packages for Traxxas 2WD models.
• Cross-Compatible Design — Beyond the upgrade kits they're specifically designed for, these extreme heavy-duty caster blocks remain fully compatible with non-EHD (non-extreme heavy-duty) parts as well as Traxxas aluminium accessories, giving you maximum flexibility in building your ideal setup.
• Includes Complete Hardware — The package comes with everything you need for installation: two 3x26mm hinge pins and two 3x15mm ball cup screws (BCS), eliminating the need to source additional hardware separately.
• Superior Steering Control — By maintaining precise wheel geometry even under extreme stress, these caster blocks ensure consistent and responsive steering characteristics throughout high-speed runs and challenging terrain.

Technical Performance

The extreme heavy-duty caster blocks represent a significant engineering upgrade over standard components. Manufactured by Traxxas with meticulous attention to detail, these parts are designed specifically for the demands of serious RC car enthusiasts in the UK who refuse to compromise on durability. The extra material incorporated throughout the caster block structure provides substantially greater resistance to breakage under the enormous stresses generated during aggressive driving, competitive racing, and high-impact terrain interactions. The geometry of these blocks directly influences your vehicle's caster angle, camber, and overall front-end handling characteristics, making them critical to achieving optimal performance. When paired with the #9180 or #9181 upgrade kit, these blocks become part of a complete heavy-duty suspension system engineered to dramatically increase durability compared to standard setups. The inclusion of quality hinge pins (3x26mm) and ball cup screws (3x15mm) ensures that installation is straightforward and that all components work together harmoniously. The blue colour finish not only provides visual appeal but also helps with identification and organisation when managing multiple RC vehicles or spare parts. These blocks maintain their performance characteristics across a wide range of driving conditions, from smooth track surfaces to rough off-road terrain, and they remain compatible with both EHD and standard Traxxas components, allowing builders to mix and match based on their specific needs and preferences.

Frequently Asked Questions

• Which Traxxas models are these extreme heavy-duty caster blocks compatible with? — These caster blocks are designed as standard replacements for the #9180 and #9181-series 2WD Extreme Heavy-Duty Upgrade Kits. They are compatible with models including the Rustler (including Rustler HD), Slash (including Slash HD), Stampede, and Bigfoot. They also work with non-EHD parts and Traxxas aluminium accessories, providing versatility across multiple Traxxas 2WD vehicles.
• What is the difference between extreme heavy-duty caster blocks and standard blocks? — Extreme heavy-duty caster blocks feature significantly more material throughout their construction, making them substantially stronger and more durable under stress. They're engineered to resist breakage during aggressive driving, competitive racing, and high-impact impacts, whereas standard blocks are designed for more moderate use. If you frequently bash your RC car or compete seriously, the extreme heavy-duty version offers considerably better longevity.
• Can I use these blocks if I haven't purchased the full upgrade kit? — Yes, these caster blocks are compatible with non-EHD parts as well as standard Traxxas aluminium accessories. This means you can upgrade to these extreme heavy-duty blocks as a standalone component if you wish to strengthen just the caster block area of your vehicle without purchasing a complete upgrade kit.
• What tools do I need to install these caster blocks? — You'll need basic RC maintenance tools including hex wrenches and possibly a screwdriver, depending on your vehicle model. The blocks come with the necessary hinge pins and ball cup screws for installation, but the specific installation process will depend on your particular Traxxas model. Consult your vehicle's manual for detailed installation instructions.
• Are these suitable for beginners? — While these parts are excellent quality and represent a worthwhile upgrade, they're specifically designed for users who want maximum durability and are willing to invest in premium components. Beginners with ready to run RC cars can certainly use them, but they're particularly valuable for experienced drivers who push their vehicles hard and want reduced maintenance and breakage.
• Why do the caster blocks come in different colours? — Traxxas offers these extreme heavy-duty caster blocks in multiple colours (blue, black, red, and grey) primarily for visual preference and vehicle customisation. All colours are functionally identical and offer the same extreme heavy-duty construction and performance characteristics. Choose based on which colour best matches your vehicle's scheme.
