Traxxas Steering blocks, 6061-T6 aluminium (dark titanium-anodised) (left & right)/ 2.5x12mm BCS (with threadlock) (2)/ 2x6mm SS (with threadlock) (4) TRX9737-GRAY

Overview

The Traxxas TRX9737-GRAY Steering Blocks represent a premium upgrade for your TRX-4M trail truck, delivering professional-grade durability and precision handling. Machined from tough 6061-T6 aluminium and finished in a striking dark titanium-anodised coating, these steering blocks are engineered to enhance your RC car's steering response whilst maintaining the factory trail-tuned geometry that makes the TRX-4M such a capable off-road performer. Whether you're running a Ford Bronco, Land Rover Defender, Chevrolet K10, or Ford F-150 variant, these heavy-duty steering blocks provide the strength upgrade your RC machine needs for serious trail work and aggressive bashing.

For RC enthusiasts in the UK seeking to maximise their TRX-4M's potential, this is one of the most popular hop-ups available. The steering blocks don't just look fantastic with their brilliant anodised finish—they fundamentally improve how your truck handles on technical terrain. By replacing the stock plastic components with machined aluminium, you're gaining a significant durability advantage whilst preserving the carefully calibrated suspension and steering geometry that Traxxas engineers have tuned into the TRX-4M platform. This makes them ideal for anyone who takes their ready-to-run RC truck seriously, from weekend bashers to trail enthusiasts who demand rock-solid performance.

Installation is straightforward, and the included hardware ensures a proper fit and long-term reliability. The threadlock-equipped fasteners mean your steering blocks will stay securely mounted even during aggressive driving sessions. If you're looking to build the ultimate TRX-4M trail setup, these aluminium steering blocks should be high on your upgrade list alongside other durability enhancements.

Key Features

• 6061-T6 Aluminium Construction — These steering blocks are machined from aerospace-grade 6061-T6 aluminium, one of the strongest and most reliable aluminium alloys available for RC applications. This material choice ensures exceptional durability without excessive weight, allowing your truck to maintain balanced handling whilst withstanding the punishment of serious trail driving and rock crawling.
• Dark Titanium-Anodised Finish — The brilliant dark titanium-anodised coating doesn't just add high-tech style to your off-road machine; the anodising process creates a protective layer that resists corrosion, oxidation, and wear from dirt, mud, and water exposure. This finish maintains its appearance even after extended use in harsh conditions typical of UK trail environments.
• Left and Right Steering Blocks Included — You receive a complete pair of steering blocks (left and right), eliminating the need for separate purchases and ensuring perfectly matched geometry on both sides of your truck's front end.
• Preserved Trail-Tuned Geometry — Rather than alter the carefully engineered steering and suspension geometry that Traxxas has tuned into the TRX-4M, these aluminium blocks maintain the factory specifications. This means you gain durability without sacrificing the truck's renowned handling characteristics and trail-capable suspension performance.
• Threadlock-Equipped Hardware — The complete fastener kit includes 2.5x12mm button-cap screws (BCS) and 2x6mm stainless steel (SS) screws, all pre-treated with threadlock compound. This feature prevents fasteners from vibrating loose during aggressive driving, ensuring your steering blocks remain securely mounted through extended trail sessions and intense bashing.
• Stainless Steel Fasteners — The 2x6mm stainless steel screws resist rust and corrosion, maintaining their integrity even when exposed to mud, water, and salt conditions common in UK trail driving. This attention to material quality ensures your upgrade maintains its reliability for years to come.
• Increased Steering Precision — By replacing plastic components with rigid aluminium, you're eliminating flex and deflection in the steering system. This delivers more direct, responsive steering feedback, allowing you to navigate technical terrain with greater accuracy and control—a noticeable improvement that serious RC drivers will appreciate immediately.

Technical Performance

These steering blocks represent a significant engineering upgrade over stock plastic components. The 6061-T6 aluminium construction delivers superior rigidity, eliminating the flex and movement inherent in plastic steering blocks. When you're navigating rocky trail sections or pushing your TRX-4M through challenging terrain, this increased stiffness translates directly into more precise steering response and faster correction capability. The machined construction ensures tight tolerances and perfect alignment, maintaining the truck's factory geometry whilst adding durability. The dark titanium-anodised finish provides more than aesthetic appeal; the anodised layer offers genuine protection against wear, corrosion, and the abrasive effects of dirt and mud exposure during UK trail driving. The complete fastener package—comprising 2.5x12mm button-cap screws with threadlock and 2x6mm stainless steel screws, also with threadlock—ensures your upgrade stays securely in place even during aggressive bashing sessions. Stainless steel fasteners resist corrosion far better than standard steel, maintaining reliability whether you're driving in dry conditions or the wet UK climate. Installation is straightforward and requires only basic tools; simply disassemble your truck's front steering assembly, remove the plastic blocks, and install the aluminium replacements using the provided hardware. The process takes approximately 20-30 minutes for someone with basic RC mechanical experience.

Frequently Asked Questions

• Will these steering blocks improve my TRX-4M's handling? — Yes, significantly. Plastic steering blocks flex and deflect during aggressive driving, which reduces steering precision and responsiveness. These machined aluminium blocks are substantially more rigid, eliminating that flex and delivering noticeably sharper, more direct steering feedback. You'll feel the improvement immediately when tackling technical terrain or making quick directional corrections during trail driving.
• Are these steering blocks suitable for beginners? — Absolutely. Whilst these blocks are a durability upgrade typically appreciated by experienced RC drivers, the installation process is straightforward enough for anyone with basic mechanical skills. If you're new to RC maintenance, this is an excellent first upgrade project to build your confidence—the process is simple, clearly documented, and requires only basic tools.
• How do these compare to stock plastic steering blocks? — Stock plastic steering blocks are designed for basic driving, but they flex under load and wear quickly in challenging conditions. These 6061-T6 aluminium blocks maintain their shape perfectly, providing superior precision and durability. They'll last significantly longer, maintain consistent steering geometry, and deliver better handling response. For serious trail driving or regular bashing, the upgrade is genuinely noticeable and worthwhile.
• Will I need to adjust anything after installing these blocks? — No, these steering blocks maintain the TRX-4M's factory-tuned geometry perfectly. Simply install them using the provided hardware and you're ready to drive. The threadlock-equipped fasteners ensure they'll stay secure through extended use without requiring regular re-tightening.
• What's the advantage of the dark titanium-anodised finish? — Beyond the striking appearance that adds high-tech style to your machine, the anodised coating provides genuine protection against corrosion, oxidation, and wear. It resists the abrasive effects of dirt, mud, and moisture exposure—particularly valuable for UK drivers dealing with damp trail conditions. The finish maintains its appearance and protective qualities for years of reliable use.
• Are these steering blocks compatible with aftermarket suspension upgrades? — Yes. These blocks integrate seamlessly with other TRX-4M durability upgrades. Many users combine them with heavy-duty shocks, aluminium caster blocks (with appropriate front arms), and reinforced linkages to build a comprehensive durability package. Consult the TRX-4M's exploded views documentation if you're planning multiple simultaneous upgrades.
• Do I need any special tools to install these blocks? — No special tools are required. A basic Phillips screwdriver or hex driver (depending on your truck's fastener style) and a screwdriver with a 2.5mm socket head size are all you'll need. The straightforward design allows installation without hydraulic presses or specialised RC workshop equipment.
