Overview
The Traxxas Steering Blocks and Caster Blocks (C-Hubs) TRX9732 are essential replacement chassis components designed for the TRX-4M series of 1/18 scale RC crawlers and trail trucks. Whether you're a dedicated RC enthusiast in the UK running Traxxas TRX-4M models or a serious basher who demands reliability from their RC car UK setup, these steering blocks and caster blocks are critical front-end components that determine your vehicle's handling, steering response, and overall trail performance. As genuine Traxxas OEM parts, they ensure perfect compatibility and maintain the original factory specifications of your TRX-4M platform.
The steering and caster blocks form the cornerstone of your RC crawler's front suspension geometry, directly affecting how your vehicle responds to steering inputs, maintains caster angle for stability, and performs over challenging terrain. If you've experienced worn steering response, loose handling, or visible damage to your front-end geometry, replacing these blocks will restore your TRX-4M to factory performance standards. These are not aftermarket alternatives—they're the exact components Traxxas designed and engineered specifically for their TRX-4M platform, guaranteeing seamless integration with all other chassis components.
Available now in the UK through RC Model Shop, this complete left and right steering block and caster block set represents an investment in your TRX-4M's longevity and performance. Whether you're preparing your ready to run RC truck for competitive trail courses or simply maintaining your bashable 1/18 scale crawler, these OEM components deliver the precision and durability Traxxas is renowned for.
Key Features
- Complete Left and Right Steering Blocks — This set includes both left and right steering blocks, allowing you to replace either or both sides depending on your maintenance needs. Steering blocks are the critical pivot points where your servo linkage connects to the wheels, and having matched OEM components ensures consistent steering geometry and response across both sides of your RC vehicle.
- Complete Left and Right Caster Blocks (C-Hubs) — The caster blocks, also called C-hubs, control the caster angle of your front wheels—the forward tilt that improves stability and steering feel. This complete set ensures your TRX-4M maintains perfect caster geometry, which is essential for predictable handling on rocks, roots, and technical trail terrain that characterises crawling courses across the UK.
- Genuine Traxxas OEM Components — These are official Traxxas factory parts, not aftermarket substitutes. When you purchase OEM steering and caster blocks, you're getting components engineered and tested by Traxxas to exacting standards, ensuring compatibility, durability, and performance identical to your vehicle's original specification.
- Perfect Compatibility with TRX-4M Series — These blocks are engineered specifically for all TRX-4M models, including the Ford Bronco, Land Rover Defender, Chevrolet K10 High Trail Edition, and Ford F-150 High Trail Edition variants, as well as the TRX-4MT Monster Truck versions. Whether your RC crawler features the Bronco body, Defender styling, or truck aesthetics, these components maintain perfect factory fit.
- Restores Factory Steering Precision — Over time, steering blocks and caster blocks experience wear from constant articulation, impact, and the stresses of crawling and bashing. Replacing them with OEM Traxxas components restores the precise steering geometry and front-end feel that makes your TRX-4M responsive and predictable on the trail.
- Durable Construction — Traxxas engineers these steering and caster blocks to withstand the demands of serious crawling and bashing, with reinforced geometry designed to handle impacts and sustained off-road use without flexing or wearing prematurely.
- Essential Maintenance Component — If you've bent a steering block, damaged a caster block, or simply want to refresh your TRX-4M's front-end assembly, this set provides everything needed to restore your chassis to like-new condition and eliminate any play or slop in the steering.
Technical Performance
The steering blocks and caster blocks represent the physical interface between your TRX-4M's suspension, steering servo, and wheels. These components are engineered from durable materials designed to resist the impacts and stresses inherent in 1/18 scale trail crawling and RC bashing. The steering blocks form the connection point where your servo linkage translates electrical servo commands into physical wheel movement, while the caster blocks establish the angular geometry that affects wheel camber and caster angle. Traxxas designs and manufactures these components to incredibly tight tolerances, ensuring that when you replace worn or damaged blocks with this genuine TRX9732 set, you're restoring your vehicle to original factory specifications. The geometry is crucial: proper caster angle (the forward tilt of the steering axis) improves steering feedback and stability, whilst correct steering block alignment ensures your wheels respond immediately and predictably to servo input. Whether you're tackling rocky terrain, crawling over roots, or bashing through rough ground, these OEM blocks maintain the structural integrity and responsive handling characteristics that make the TRX-4M platform so popular amongst UK RC enthusiasts. Each block is engineered to provide years of reliable service when properly maintained, and replacement is a straightforward maintenance task that any TRX-4M owner can undertake with basic tools.

Frequently Asked Questions
- Are these steering blocks compatible with all TRX-4M models? — Yes, the TRX9732 steering blocks and caster blocks are engineered to fit all TRX-4M variants, including the Ford Bronco (all colours), Land Rover Defender (all colours), Chevrolet K10 High Trail Edition (all colours), Ford F-150 High Trail Edition (all colours), and TRX-4MT Monster Truck versions. They maintain perfect factory compatibility across the entire TRX-4M platform.
- How do I know when my steering blocks need replacing? — Common signs that your steering blocks need replacement include loose or sloppy steering feel, visible cracks or bends in the plastic blocks, difficulty steering straight, uneven tyre wear caused by misaligned wheels, or obvious damage from impacts. If you've had a significant crash or noticed your TRX-4M's steering has become unpredictable, these blocks are the first components to inspect.
- What is the difference between steering blocks and caster blocks? — The steering blocks (also called steering knuckles) connect your servo linkage to the wheels and allow the wheels to turn left and right. The caster blocks (or C-hubs) control the caster angle—the forward tilt of the steering axis. Both are essential for proper steering and handling, and both are included in this complete TRX9732 set.
- Is this suitable for beginners? — Whilst this product is a spare part rather than a complete vehicle, replacing steering and caster blocks is well within the capabilities of any RC enthusiast, from complete beginners to experienced competitors. The installation is straightforward and requires only basic hand tools, making this an excellent maintenance task for learning more about your TRX-4M's chassis geometry.
- Are these genuine Traxxas parts? — Yes, the TRX9732 is an official Traxxas part number and represents genuine OEM components manufactured by Traxxas. Purchasing genuine OEM steering and caster blocks ensures perfect compatibility, exact fit, and performance characteristics identical to your vehicle's original specification.
- Can I use aftermarket steering blocks instead? — Whilst some aftermarket options exist, genuine Traxxas OEM components like the TRX9732 are engineered specifically for the TRX-4M platform and offer the most reliable fit, geometry, and durability. OEM blocks ensure your RC crawler performs exactly as Traxxas intended.
