Traxxas Extreme Heavy Duty Caster Blocks Left Right Grey Pair TRX9032-GRAY

Overview

The Traxxas Extreme Heavy-Duty Caster Blocks in grey represent a significant upgrade for your RC car UK enthusiast setup. These left and right caster blocks (also known as C-hubs) are engineered specifically for drivers who demand the absolute maximum durability and strength from their suspension components. Whether you're a serious basher pushing your 4WD RC truck to the limits or a racer who refuses to compromise on reliability, these extreme heavy-duty upgrades deliver the reinforced performance you need to keep your RC model running at peak performance, even under the most demanding conditions.

If you own a Traxxas Hoss 4X4 VXL, Rustler 4X4 VXL, Slash 4X4, or Ultimate Slash 4X4 VXL, these caster blocks are specifically designed to transform your suspension into a fortress of strength. Built to take a pounding that would snap standard caster blocks, the extreme heavy-duty design features beefed-up construction with extra material strategically placed throughout to provide exceptional rigidity and durability. These are genuine Traxxas performance parts that have been tested and proven in the field by RC enthusiasts across the UK and beyond, making them an essential upgrade for anyone serious about their RC hobby.

As part of the #9080 upgrade kit specifications, these caster blocks represent the gold standard in suspension reinforcement for 2WD Extreme Heavy-Duty Upgrade Kits. The investment in these components pays dividends immediately, as you'll notice fewer broken suspension components, longer run times between repairs, and the confidence that comes with knowing your RC car's front end can handle whatever you throw at it. This is the kind of genuine, authorised Traxxas upgrade that serious RC car enthusiasts in the UK recognise as essential maintenance and performance enhancement.

Key Features

• Extreme Heavy-Duty Construction — These caster blocks are beefed up with extra material throughout their design, providing significantly more strength and durability than standard components, which means they can withstand impacts, jumps, and hard cornering that would damage regular suspension parts.

• Compatible with #9080 Upgrade Kit — These blocks are specifically engineered as standard replacements for 9180 and 9181-series 2WD Extreme Heavy-Duty Upgrade Kits, ensuring perfect fitment and performance integration with your existing upgrade kit.
• Cross-Compatible with Non-EHD Parts — Beyond their primary compatibility with EHD kits, these caster blocks also work with non-EHD suspension parts as well as genuine Traxxas aluminium accessories, giving you flexibility in how you configure your RC car's suspension.
• Genuine Traxxas Component — As an official Traxxas spare part, you can be confident in the quality, fitment, and performance characteristics of this component, backed by the manufacturer's engineering expertise and reputation.
• Includes Essential Hardware — The package comes complete with 3x32mm hinge pins (2 pieces) and 3x20mm ball cup screws (2 pieces), providing all the fastening hardware needed for proper installation.
• Suitable for Multiple Traxxas Models — These caster blocks fit a range of popular Traxxas 4X4 vehicles, including the Hoss 4X4 VXL, Rustler 4X4 VXL, Slash 4X4, and Ultimate Slash 4X4 VXL, making this a versatile upgrade for various RC car setups.

Technical Performance

The engineering behind these extreme heavy-duty caster blocks centres on reinforced material density and strategic geometry that absorbs and dissipates impact forces more effectively than standard suspension components. Traxxas has added extra material throughout the design to create a structure that maintains its integrity under extreme driving conditions — whether that's high-speed bashing through rough terrain, aggressive jump landings, or the repetitive stress of competitive racing. The 3x32mm hinge pins (2 pieces) and 3x20mm ball cup screws (2 pieces) provided with these blocks are precision-engineered fastening hardware specifically selected to work seamlessly with the caster block geometry. The blocks themselves are designed to maintain perfect alignment characteristics across the front suspension, ensuring consistent handling whether you're running on grass, dirt, concrete, or asphalt. For RC enthusiasts across the UK who regularly compete or push their vehicles hard, the durability benefit is immediate and obvious — fewer broken components means more track time and less frustration dealing with repairs.

• What makes these extreme heavy-duty compared to standard caster blocks? — The extreme heavy-duty design features extra material strategically added throughout the block structure to provide significantly more strength and rigidity.

These are the fastening hardware specifically engineered to work with these caster blocks, so you can proceed with installation without needing to source additional components.
• Are these blocks compatible with other Traxxas suspension parts? — Beyond their primary use with the #9080 upgrade kit, these extreme heavy-duty caster blocks are also compatible with non-EHD parts as well as genuine Traxxas aluminium accessories. This gives you flexibility in customising your suspension setup and choosing which components to upgrade. You can use these blocks even if you haven't upgraded your entire front suspension to the extreme heavy-duty standard.
• What colour are these caster blocks? — These blocks come in grey, giving your RC car a distinctive appearance that clearly shows you've upgraded to the premium extreme heavy-duty suspension components. The grey finish is durable and designed to withstand regular use and the outdoor environment.
• How do I know if I need a caster block upgrade? — If you regularly experience broken caster blocks after crashes or hard driving, find yourself spending significant time repairing suspension damage, or simply want to drive with more confidence knowing your suspension can handle extreme impacts, these extreme heavy-duty blocks are for you. They're a popular upgrade among UK RC car bashers and racers who push their vehicles hard and want maximum durability between repairs.
