TRX9787

Overview

Upgrade your Traxxas TRX-4M with these premium aluminium axle covers, engineered to enhance both the appearance and performance of your 1/18 scale RC crawler. Whether you're a dedicated RC enthusiast in the UK looking to customise your trail truck or someone seeking genuine Traxxas spare parts to maintain your investment, these axle covers are an essential upgrade that delivers real functional benefits alongside high-tech styling. Made from tough 6061-T6 aluminium and finished in dark titanium anodised coating, these covers transform the look of your TRX-4M whilst providing measurable improvements to handling and climbing capability.

The TRX9787 axle covers are specifically designed for the Traxxas TRX-4M range, compatible with all Ford Bronco, Land Rover Defender, Chevrolet K10, Ford F-150 and TRX-4MT Monster Truck variants. These professional-grade upgrades represent the kind of attention to detail that separates serious RC rock crawlers from casual bashers. By adding strategic weight to the lowest point of your chassis, these covers improve your truck's centre of gravity and dramatically enhance anti-rollover stability, making them ideal for tackling challenging terrain and steep climbs.

RC enthusiasts across the UK who demand quality components for their ready to run RC vehicles will appreciate the engineering excellence Traxxas brings to every product. These axle covers are not just aesthetic upgrades—they're functional performance parts that make a genuine difference in how your TRX-4M handles difficult obstacles and uneven ground.

Key Features

• Premium 6061-T6 Aluminium Construction — These axle covers are manufactured from aerospace-grade 6061-T6 aluminium alloy, one of the strongest and most reliable aluminium options available for RC parts, ensuring they will withstand years of challenging trail driving without cracking, bending or degrading.
• Dark Titanium Anodised Finish — The professional dark titanium anodised coating provides a stunning high-tech appearance that catches light beautifully, whilst also offering enhanced corrosion resistance and durability compared to raw aluminium, meaning your upgrade will look fresh and maintain its appearance through countless driving sessions.
• Improves Anti-Rollover Stability — By adding 8 grams of weight precisely positioned at the lowest point of your chassis, these covers lower your vehicle's centre of gravity and significantly improve stability when navigating steep slopes, side hills and technical rocky terrain, reducing the risk of tip-overs on challenging trails.
• Enhanced Rock-Climbing Capability — The improved weight distribution and lower centre of gravity translate directly into superior climbing performance, allowing your TRX-4M to tackle steeper obstacles and maintain better traction and control when ascending rocky inclines and challenging vertical climbs.
• Genuine Traxxas OEM Parts — These are official Traxxas replacement parts engineered to exact specifications, ensuring perfect fitment and compatibility with your TRX-4M without modification or adjustment required.
• Complete Hardware Included — The package includes eight 1.6x12mm BCS screws with threadlock applied, giving you everything needed for immediate installation without hunting for separate fasteners.
• Professional Anodised Finish — The anodising process creates a hard, wear-resistant surface that resists scratches, UV fading and weather damage, maintaining the sophisticated dark titanium colour through seasons of outdoor RC driving.

Technical Performance

The Traxxas TRX9787 axle covers represent a carefully engineered approach to performance enhancement through strategic weight distribution. Manufactured from 6061-T6 aluminium, this specific alloy offers an excellent balance of strength-to-weight ratio, making it ideal for RC applications where durability must be maintained without excessive mass. Each pair of covers adds precisely 8 grams of weight, deliberately positioned at the lowest extremity of your TRX-4M chassis to create a measurable improvement in stability metrics and handling characteristics. The dark titanium anodised finish is not merely decorative—the anodising process creates a hardened oxide layer on the aluminium surface that significantly improves corrosion resistance, scratch resistance and overall longevity of the parts. This is particularly important for UK RC hobbyists who frequently drive in wet conditions and muddy terrain where untreated aluminium would quickly oxidise and deteriorate. The engineering behind these covers demonstrates Traxxas's philosophy of combining form with function, ensuring that upgrades enhance both the visual appeal and real-world performance of your TRX-4M. For serious rock crawlers and trail enthusiasts operating RC vehicles in demanding conditions, this type of precision engineering at the component level is what separates reliable platforms from those prone to frustration.

Frequently Asked Questions

• What is the weight added by these axle covers? — Each pair of TRX9787 axle covers adds 8 grams of weight to your TRX-4M, strategically positioned at the lowest point of the chassis to improve centre of gravity and stability without creating handling issues.
• Will these covers fit my TRX-4M? — Yes, the TRX9787 covers are specifically engineered for the complete Traxxas TRX-4M range, including the Ford Bronco (all colours), Land Rover Defender (all colours), Chevrolet K10, Ford F-150, and TRX-4MT Monster Truck variants. They require no modification for installation.
• Are these covers just for looks or do they actually improve performance? — These are genuine performance-enhancing upgrades, not just cosmetic additions. By adding weighted mass at the lowest point of your chassis, they meaningfully improve anti-rollover stability and rock-climbing capability—benefits you will notice immediately when driving technical terrain.
• What does anodised aluminium mean and why does it matter? — Anodising is an electrochemical process that creates a hardened oxide layer on the aluminium surface. The dark titanium anodised finish on these covers provides superior corrosion resistance (essential for UK weather conditions), enhanced scratch resistance, and improved durability compared to bare aluminium that would quickly oxidise and degrade when exposed to moisture and mud.
• How do I install these covers? — Installation is straightforward—the package includes all eight 1.6x12mm BCS screws with threadlock pre-applied, so you simply position the covers on your axles and secure them with the provided fasteners. Threadlock is already applied to prevent vibration loosening during driving.
• Can I use these on other Traxxas models? — These covers are specifically designed for the TRX-4M range. Whilst they may fit some other models physically, Traxxas engineers each product for specific platforms, so using them on incompatible models could affect performance or fitment.
• Do these need any maintenance? — The anodised finish is durable and low-maintenance. Occasionally rinse them with fresh water after muddy driving sessions and dry them to keep the finish looking pristine. The anodising provides excellent corrosion resistance, so they will maintain their appearance through extended use.
