Overview
The Traxxas Caster blocks (c-hubs), extreme heavy duty, Grey (left & right) represent a premium suspension upgrade for serious RC enthusiasts in the UK who demand maximum strength and durability from their RC car components. These upgraded caster blocks are specifically engineered for the 9180 and 9181-series 2WD Extreme Heavy Duty Upgrade Kits, making them an essential replacement part for anyone running these systems. Whether you're a competitive racer, a weekend basher, or a dedicated hobbyist looking to enhance your RC vehicle's performance, these extreme heavy duty caster blocks deliver the reinforced engineering you need to handle the most demanding driving conditions.
Built with extra material throughout their construction, these grey caster blocks are beefed up significantly compared to standard components, providing enhanced strength and durability that can withstand the punishment of intense RC driving sessions. The extreme heavy duty design means they won't fail when you're pushing your RC car to its limits on rough terrain, during high-speed runs, or when executing aggressive manoeuvres. These are the caster blocks that serious RC car UK enthusiasts choose when they want a suspension upgrade that truly makes a difference in performance and longevity.
What sets these Traxxas caster blocks apart is their proven compatibility and quality engineering. They work as standard replacements within the 9180 and 9181-series systems, but they're also compatible with non-EHD (non-Extreme Heavy Duty) parts as well as Traxxas aluminium accessories, giving you flexibility in your build configuration. The grey colour option provides excellent visibility during outdoor driving sessions and offers a distinctive aesthetic that stands out on the track or the bash course.

Technical Performance
The extreme heavy duty caster blocks represent a significant engineering upgrade in suspension technology for 2WD RC vehicles. These components are constructed with extra material distribution throughout their structure, which increases their strength-to-weight ratio and provides superior durability during aggressive driving. The use of precision-engineered hinge pin mounting points (3x26 mm) ensures reliable articulation and consistent handling characteristics, while the 3x15 mm BCS fasteners provide secure attachment to adjacent suspension components. This level of engineering detail is what separates these caster blocks from standard alternatives—they're built to absorb punishment, maintain dimensional accuracy under stress, and deliver consistent performance session after session. The compatibility with both EHD and non-EHD systems demonstrates Traxxas's commitment to modular design, allowing RC enthusiasts to progressively upgrade their vehicles without replacing entire suspension assemblies. For UK-based RC car users who demand the highest standards of build quality and long-term reliability, these extreme heavy duty caster blocks represent the gold standard in suspension upgrades.
