TRX9787-RED

Overview

Transform your TRX-4M trail truck with premium Traxxas aluminium axle covers that deliver both stunning high-tech style and genuine performance benefits. These red-anodised covers are engineered to enhance your 1/18 scale RC crawler's handling characteristics whilst adding a striking visual upgrade to your rig. Whether you're tackling rocky terrain, climbing steep inclines, or simply want to elevate your TRX-4M's appearance, these aluminium axle covers are an essential upgrade for any serious RC enthusiast in the UK who demands both form and function.

Built from tough 6061-T6 aluminium alloy, these precision-machined covers represent the kind of quality engineering Traxxas is renowned for across their entire range of brushless RC trucks and crawlers. The red-anodised finish not only looks fantastic—it pairs perfectly with compatible TRX-4M models or provides striking contrast depending on your truck's colour scheme. These are genuine Traxxas parts, guaranteed to deliver the quality, precision and value you expect from The Fastest Name In Radio Control.

Beyond aesthetics, the axle covers serve a critical functional purpose by adding valuable weight to the lowest part of your TRX-4M chassis. This strategic weight distribution significantly improves anti-rollover stability, meaning your truck stays planted through aggressive cornering and technical rock-crawling sections. The improved low centre of gravity also enhances your TRX-4M's superior rock-climbing capability, giving you more confident control when tackling steep obstacles and uneven terrain. For RC car enthusiasts in the UK looking to squeeze every ounce of performance from their trail truck investment, these aluminium covers are a must-have upgrade.

Key Features

• Premium 6061-T6 Aluminium Construction — The axle covers are machined from aerospace-grade 6061-T6 aluminium alloy, the same material used in professional-grade RC racing components. This material choice ensures exceptional durability, corrosion resistance, and lightweight performance without compromising strength, making these covers suitable for intense bashing, rock-crawling, and competitive trail driving.
• Vibrant Red-Anodised Finish — The bright red anodised coating provides superior durability and weather resistance compared to painted alternatives, maintaining its vivid colour through countless runs in mud, water, and challenging terrain. The anodised surface also resists scratching and fading, ensuring your upgrade looks fresh season after season of RC driving.
• Improved Anti-Rollover Stability — By strategically adding weight to the lowest point of the chassis, these covers lower your TRX-4M's centre of gravity and dramatically improve resistance to rolling over during aggressive cornering, high-speed runs, or technical climbing manoeuvres. This is particularly valuable for UK RC trails where uneven ground and obstacle courses demand absolute stability.
• Enhanced Rock-Climbing Capability — The improved weight distribution provided by the axle covers gives your TRX-4M superior traction and control when climbing steep rock faces and vertical obstacles, translating to better grip and more consistent climbing performance that separates confident drivers from the rest.
• Complete with Fasteners — The package includes eight precision-engineered 1.6x12mm BCS screws with threadlock compound pre-applied, ensuring secure installation that won't work loose during aggressive off-road driving. No hunting for compatible fasteners—everything needed for installation is included in the box.
• Precision Fit Design — These covers are engineered specifically for TRX-4M models, guaranteeing perfect fitment without modification. The precision machining means bolt holes align perfectly and the covers sit flush against the axle carrier without gaps or misalignment.

Technical Performance

The Traxxas TRX-4M axle covers represent a masterclass in materials engineering for RC vehicles. Machined from 6061-T6 aluminium—a premium aerospace alloy prized for its strength-to-weight ratio—these covers deliver uncompromising durability whilst remaining lightweight enough not to burden your truck's acceleration or responsiveness. The 6061-T6 alloy is specifically selected because it offers superior machinability, excellent corrosion resistance, and maintains structural integrity even under extreme stress conditions that brushless RC crawlers regularly experience. The anodised finish provides a hard oxide layer that's far more durable than paint, resisting the abrasive effects of sand, mud, and rock contact that would quickly wear through conventional finishes. Each pair of covers includes eight 1.6x12mm stainless steel fasteners with applied threadlock, guaranteeing that your upgrade stays securely attached through thousands of kilometres of trail driving. The strategic placement of these covers on the lowest part of the TRX-4M chassis directly impacts performance by lowering the vehicle's centre of gravity, which fundamentally improves handling dynamics across all driving scenarios—from smooth technical rock-crawling to high-speed trail running where stability is paramount.

Frequently Asked Questions

• Will these axle covers fit my TRX-4M trail truck? — Yes, these covers are engineered specifically for all TRX-4M models, including the Ford Bronco variants, Land Rover Defender versions, Chevrolet K10 High Trail Truck, and Ford F-150 High Trail Truck configurations. They're also compatible with TRX-4MT Monster Truck variants. Simply verify your model number matches the compatible list provided, and installation is straightforward.
• What colour options are available? — The red-anodised finish shown here is the standard offering. Traxxas also manufactures these same aluminium axle covers in green-anodised and dark titanium-anodised versions, allowing you to coordinate with your TRX-4M's colour scheme or create striking contrast combinations that really make your rig stand out at UK RC trails and crawling events.
• How much weight do these covers add to my TRX-4M? — Whilst the source materials don't specify exact weight, the strategic placement of these aluminium covers on the lowest part of your chassis means they add valuable weight precisely where it benefits handling most—at the centre of gravity. This is far more effective than weight added higher up on the frame, which can negatively impact performance.
• Are these covers difficult to install? — Installation is straightforward and requires only basic tools—a hex key or screwdriver depending on your preferred fastener type. The covers simply bolt onto your TRX-4M's axle carriers using the eight included 1.6x12mm fasteners. The threadlock compound is already applied, so you simply need to position the covers and tighten the screws securely. Most users complete installation in under 15 minutes per side.
• Will these covers improve my TRX-4M's performance immediately? — Yes, the performance benefits are noticeable immediately after installation. The improved anti-rollover stability becomes apparent during the first run, particularly when navigating tight corners or climbing technical obstacles. You'll feel more confident pushing your TRX-4M harder because the vehicle feels more planted and controlled. The enhanced rock-climbing capability translates to better traction on steep inclines and obstacle courses.
• How durable is the anodised finish? — The red-anodised finish is significantly more durable than painted alternatives. The anodising process creates a hard oxide layer that's bonded at the molecular level to the underlying aluminium, making it resistant to scratching, chipping, and fading. After years of RC trail driving in mud, water, and rocky terrain, the anodised finish will maintain its vibrant appearance far better than any paint. The finish is also self-healing to some degree, as the oxide layer continues to protect the base metal even if minor scratches occur.
• Can I use these covers on other Traxxas models? — These covers are specifically engineered for TRX-4M scale trail trucks and are not compatible with other Traxxas platforms like the X-Maxx, Sledge, or Hoss models. Each Traxxas model has unique suspension geometry and axle carrier designs, so covers must be model-specific for proper fitment and performance benefits.
• Are genuine Traxxas fasteners really necessary? — Whilst the included fasteners are Traxxas-engineered and pre-treated with threadlock for reliability, standard M1.6x12mm stainless steel screws with threadlock compound applied would work as replacements if needed. However, using genuine Traxxas fasteners ensures perfect compatibility and guarantees the threadlock compound is correctly applied.
