TRX9787-BLUE

Overview

Elevate your TRX-4M trail truck with these premium Traxxas Axle Covers in striking blue anodised finish. Designed specifically for the TRX-4M series, including the Ford Bronco, Land Rover Defender, Chevrolet K10, and Ford F-150 variants, these aluminium covers are far more than cosmetic upgrades. They represent a strategic performance enhancement that serious RC enthusiasts and trail crawlers across the UK have come to rely on. Whether you are a dedicated rock crawler tackling technical terrain, a weekend trail basher exploring the great outdoors, or an RC enthusiast looking to fine-tune your TRX-4M for maximum capability, these axle covers deliver measurable benefits that directly improve how your vehicle performs on the trail.

Crafted from aerospace-grade 6061-T6 aluminium, these axle covers combine lightweight durability with impressive strength, ensuring they can withstand the rigours of serious off-road RC driving. The blue anodised finish not only looks fantastic and matches perfectly with various TRX-4M colour schemes, but also provides corrosion resistance and protection against the elements during extended outdoor use. Each cover weighs 8 grams, and the pair adds 16 grams of strategically placed weight to the lowest point of your chassis, creating a tangible improvement in vehicle dynamics and crawling performance.

If you are searching for TRX-4M upgrades in the UK, a performance-focused chassis tuning option, or simply want to enhance your RC trail truck with quality aftermarket components, these aluminium axle covers represent exactly what serious RC drivers are looking for. Ready to run RC vehicles benefit tremendously from weight distribution optimisation, and this Traxxas upgrade delivers that benefit with style.

Key Features

• 6061-T6 Aerospace-Grade Aluminium Construction — The covers are manufactured from premium 6061-T6 aluminium alloy, the same material specification used in high-performance aerospace applications, ensuring exceptional strength-to-weight ratio and durability that easily handles the demands of serious trail crawling and rock climbing.
• Blue Anodised Finish — The professional blue anodised coating provides both stunning visual appeal and genuine functional benefits including corrosion resistance, weather protection, and a premium appearance that complements most TRX-4M colour variants available in the ready to run RC market.
• Weight Distribution Optimisation — Each cover adds 8 grams of weight, with the pair totalling 16 grams, positioned at the lowest point of your TRX-4M chassis where it provides maximum benefit for anti-rollover stability and improved centre of gravity during technical climbing and traversal.
• Enhanced Anti-Rollover Stability — The strategic weight placement at the axle location dramatically improves your TRX-4M's resistance to rolling during steep climbs, side-slope navigation, and technical rock-crawling manoeuvres, giving you confidence and control on challenging terrain.
• Superior Rock-Climbing Capability — Lower centre of gravity combined with improved weight distribution translates directly to superior traction, articulation response, and climbing power, allowing your TRX-4M to tackle steeper gradients and more technical obstacles with noticeably better performance.
• Authentic Traxxas Engineering — These covers are genuine Traxxas parts, engineered and tested by the brand renowned for quality RC vehicles and accessories, ensuring perfect fitment, reliability, and performance benefits that third-party alternatives cannot match.
• Included Hardware Package — The set includes 8 pieces of 1.6x12mm BCS screws with threadlock, providing all fastening hardware needed for secure, vibration-resistant installation that will not come loose during aggressive RC driving.

Technical Performance

These axle covers exemplify Traxxas's commitment to precision engineering and performance optimisation. The 6061-T6 aluminium specification is not chosen arbitrarily; this particular alloy offers the ideal balance between weight and rigidity required for RC applications where every gram matters. The anodised finish undergoes a controlled electrochemical process that creates a protective oxide layer, making the covers resistant to corrosion, salt spray, and water damage—essential properties for any RC component exposed to outdoor elements and moisture during trail running sessions.

The weight distribution strategy is particularly clever. By positioning 8 grams per cover at the axle location, Traxxas engineers have identified the optimal point on the TRX-4M chassis where adding mass delivers maximum benefit. This lower centre of gravity directly counters the natural tendency of lightweight RC vehicles to roll during side slopes or steep angles. For trail crawlers and rock climbers, this translates to measurable improvements in stability, more confident line holding on technical terrain, and better power transfer during climbs. The 1.6x12mm BCS fasteners included with threadlock compound ensure that despite vibration and repeated impacts typical of serious off-road RC driving, the covers remain securely attached and will not work loose during a day at the trail.

Frequently Asked Questions

• Will these axle covers improve my TRX-4M's climbing ability? — Yes, absolutely. The strategic placement of 8 grams per cover at the lowest point of your chassis lowers the centre of gravity and improves weight distribution, which directly translates to better traction, improved articulation response, and noticeably enhanced climbing capability on steep and technical terrain. Many UK RC trail enthusiasts report measurable improvements in their ability to tackle previously challenging sections after fitting these covers.
• Are these covers suitable for all weather RC driving? — Definitely. The 6061-T6 aluminium construction combined with the blue anodised protective coating makes these covers resistant to corrosion, water damage, and salt spray. Whether you are driving in wet conditions, coastal environments, or storing your TRX-4M outdoors, the anodised finish provides excellent weather resistance that keeps the covers looking great and performing reliably.
• How much weight do these axle covers add to my TRX-4M? — The pair of covers adds a total of 16 grams to your vehicle (8 grams per cover). This is a carefully calculated amount that provides measurable performance benefits without making your RC truck sluggish or negatively impacting battery runtime or responsiveness.
• Will these covers fit my TRX-4M if I have already installed other upgrades? — These are direct OEM Traxxas parts designed specifically for the TRX-4M platform. They are engineered to integrate seamlessly with standard TRX-4M chassis components and do not conflict with typical upgrade options. However, if you have significantly modified your vehicle's suspension or axle geometry with non-standard parts, you may wish to verify compatibility before ordering.
• Is installation difficult? — Installation is straightforward for anyone with basic RC maintenance experience. The covers mount using the included 1.6x12mm BCS screws with threadlock, which secure directly to your TRX-4M's axles. The threadlock compound means you do not need to worry about vibration working the fasteners loose during aggressive driving. Most RC enthusiasts can complete installation in under 15 minutes per axle.
• Do I need any special tools to install these covers? — You will need a small Phillips head screwdriver or hex driver appropriate for 1.6mm fasteners. A set of metric hex keys or a basic RC tool kit (widely available in the UK RC hobby market) contains everything you need. No specialist tools or equipment are required.
• Will the blue anodised finish match my specific TRX-4M colour variant? — The blue anodised finish is a medium blue tone that complements all the blue-coloured TRX-4M variants beautifully. It also works well as a complementary accent on other colour variants like Black, White, Orange, Red, and the various Defender shades. Many UK RC drivers appreciate the visual consistency of matching blue covers with their blue TRX-4M bodies, while others use the contrast as a styling statement.
