Traxxas Extreme Heavy-Duty Caster Blocks Red Left Right Pair TRX9136-RED

Overview

The Traxxas Caster blocks (c-hubs), extreme heavy duty, Red (left & right) are precision-engineered suspension components designed for serious RC enthusiasts who demand maximum strength and durability from their 2WD RC vehicles. Whether you're a competitive racer pushing your RC car UK to the limits or a weekend basher who wants bulletproof reliability, these extreme heavy-duty caster blocks deliver the performance you need. Built to take a pounding, these upgraded parts are beefed up with extra material throughout their construction, making them significantly stronger than standard alternatives. If you're running a Traxxas Rustler, Slash, Stampede, or Bigfoot RC model and want to upgrade your suspension to handle more aggressive driving, these caster blocks are exactly what you need.

These left and right caster blocks are standard replacement parts specifically engineered for the Traxxas 9180 and 9181-series 2WD Extreme Heavy-Duty Upgrade Kits, which means they're designed from the ground up to work seamlessly with your existing setup. The red colour option adds visual flair to your RC car whilst maintaining that unmistakable Traxxas quality. What makes these caster blocks stand out is their extreme heavy-duty construction – they've been reinforced with additional material in all the critical stress areas, providing enhanced strength compared to standard c-hubs. This means longer service life, fewer broken parts, and more time enjoying your RC vehicle rather than fixing it.

Compatible with non-EHD parts as well as Traxxas aluminium accessories, these caster blocks offer exceptional versatility and can be integrated into various suspension setups. If you're building the ultimate ready to run RC short course truck or stadium truck platform, upgrading to these extreme heavy-duty components is one of the smartest investments you can make. The engineering is straightforward but effective – more material equals more durability, and that translates directly to better performance during intense driving sessions.

Technical Performance

The Traxxas Caster blocks represent a significant step up in suspension durability for 2WD RC vehicles in the UK market. The extreme heavy-duty design philosophy centres on reinforcing the areas where standard c-hubs typically fail – the mounting bosses, hinge pin holes, and load-bearing sections have all been beefed up with additional material. This engineering approach means you get a heavier but substantially stronger component that can handle the forces generated by brushless motors, LiPo batteries, and aggressive driving techniques. The hinge pin diameter of 3mm is optimised for the steering geometry of 2WD models like the Rustler, Slash, and Stampede, whilst the ball cup screw size of 3x15mm ensures proper articulation of the suspension without binding or play. When paired with the 9180 or 9181 upgrade kits, these caster blocks form part of a complete suspension upgrade that significantly improves durability, steering response, and overall handling characteristics. The material thickness and reinforcement placement have been carefully engineered by Traxxas to absorb impact energy and distribute loads more effectively than standard components, translating to fewer broken parts and more consistent performance lap after lap.

Frequently Asked Questions

• What models are these Traxxas caster blocks compatible with? — These extreme heavy-duty caster blocks are standard replacement parts for the Traxxas 9180 and 9181-series 2WD Extreme Heavy-Duty Upgrade Kits. They're compatible with popular 2WD models including the Rustler (all variants), Rustler HD, Slash, Slash HD, Stampede, Stampede Brushless, Bigfoot No. 1, and Ford F-150 Raptor Slash Brushless. Whilst designed specifically for these models, they're also compatible with non-EHD parts and Traxxas aluminium accessories, giving you flexibility in how you configure your suspension.
• Why should I upgrade to extreme heavy-duty caster blocks? — Standard c-hubs are the first components to break when you're driving aggressively or using a brushless motor and LiPo power system. The extreme heavy-duty versions featured here are reinforced with extra material in all the critical stress areas, meaning they absorb impacts better and last significantly longer. If you're serious about RC driving in the UK and want to minimise downtime spent fixing broken parts, upgrading to extreme heavy-duty components like these is one of the smartest investments you can make. They're especially important if you're running your RC car hard on rough terrain or at high speeds.
• Are these caster blocks easy to install? — Yes, these caster blocks are designed as drop-in replacements for your existing setup, particularly when upgrading with the 9180 or 9181 kits. Installation is straightforward and doesn't require any complex modifications. All necessary hardware is included in the package – the 3x26mm hinge pins and 3x15mm ball cup screws – so you can have your suspension upgraded and ready to go in a short time. Basic RC tools and some mechanical knowledge are helpful but not essential.
• Can I use these with non-extreme heavy-duty parts? — Absolutely. Whilst these caster blocks are the standard components for the 9180 and 9181 extreme heavy-duty upgrade kits, they're also compatible with non-EHD parts and Traxxas aluminium accessories. This compatibility gives you the flexibility to create a customised suspension setup that matches your specific driving needs and budget. You can upgrade just the caster blocks without necessarily upgrading every other suspension component.
• What colour options are available? — These extreme heavy-duty caster blocks are available in multiple colour options including red (as featured here), green, blue, and black. Choosing the red option gives you a visually striking look that matches other Traxxas extreme heavy-duty components and stands out on the track or trail. The colour is purely aesthetic and doesn't affect performance.
• Do I need anything else to complete my suspension upgrade? — These caster blocks are typically purchased as part of a complete suspension upgrade package (9180 or 9181 kits), but they can also be purchased separately as replacement parts. Depending on your current setup, you may want to upgrade other suspension components like the A-arms, turnbuckles, or shocks to get the full benefit of the extreme heavy-duty design philosophy. However, the caster blocks alone represent a significant durability upgrade and can be installed on their own if that's your preference.
