TRX7787-GRAY

Overview

Elevate the appearance and performance of your X-Series Traxxas RC monster truck or truggy with this premium Traxxas Cover, gear in sleek grey. This is not just a cosmetic upgrade—it is a genuine Traxxas accessory engineered to deliver the perfect factory fit and finish that serious RC enthusiasts demand. Whether you are running an X-Maxx Ultimate, X-Maxx Belted, XRT Ultimate, or XRT VXL-8S, this gear cover transforms the look of your brushless RC vehicle whilst providing exceptional durability and protection.

If you are shopping for RC car upgrades in the UK, you know that quality aftermarket parts can make all the difference. This aluminium gear cover is machined from high-grade 6061-T6 aluminium, the same aerospace-grade material used in professional RC racing and competition builds. The brilliant anodised finish in grey not only looks fantastic but also provides superior corrosion resistance, meaning your RC truck will maintain its showroom appearance even after hard use on the bashfield or track.

Genuine Traxxas accessories are made by Traxxas, for Traxxas, to guarantee a perfect factory fit every time. This gear cover is no exception. It slots seamlessly into your existing X-Series vehicle without any modification or adjustment required, making it an ideal upgrade for weekend bashers, competitive racers, and collectors who demand nothing but the best for their RTR RC monster trucks and truggies.

Key Features

• Machined from 6061-T6 Aluminium — The cover is milled from tough, high-grade 6061-T6 aluminium, which offers maximum rigidity and strength-to-weight ratio, ensuring your gear box is protected whilst keeping overall vehicle weight down for better handling and acceleration in RC off-road racing and bashing applications.
• Brilliant Anodised Finish — The anodised grey surface provides a premium factory appearance with exceptional durability, resisting oxidation, scratches, and weathering far better than painted finishes, making it perfect for UK weather conditions and rough bashfield use.
• Laser-Etched Logo — Features precision laser-etched Traxxas branding that adds authenticity and visual appeal, setting your RC truck apart from standard models and confirming you are running genuine Traxxas parts.
• Premium Quality Construction — Every detail has been engineered to deliver factory fit and finish, with precise tolerances that ensure the cover aligns perfectly with your vehicle's chassis and gearbox without gaps or misalignment.
• Genuine Traxxas Component — As an official Traxxas accessory, this gear cover is designed and manufactured by Traxxas engineers specifically for X-Series vehicles, guaranteeing compatibility and performance that aftermarket alternatives cannot match.
• Enhanced Aesthetics — The sleek grey anodised finish complements virtually any colour scheme and adds a professional, polished appearance to your X-Maxx or XRT, whether you are displaying it at an RC club, at the track, or using it for high-speed bashfield runs across the UK.

Technical Performance

This aluminium gear cover represents a significant step up in build quality and protection for your expensive gearbox assembly. Machined from 6061-T6 aluminium, this material is renowned in aerospace and motorsport applications for its combination of strength, lightness, and machinability. The 6061-T6 alloy offers superior rigidity compared to standard cast aluminium, meaning minimal flex under high-torque conditions during acceleration and cornering on bumpy terrain. The anodised finish is not merely decorative—anodising creates a hard, corrosion-resistant oxide layer that protects the underlying metal from dirt, moisture, salt spray, and UV exposure, critical factors for maintaining your RC truck's appearance and functionality throughout extended UK seasons. The laser-etched logo remains visible and crisp even after months of use, unlike paint or decals that fade or peel. Installation is straightforward, requiring no modification to your X-Maxx Ultimate, X-Maxx Belted, XRT Ultimate, or XRT VXL-8S chassis. The tolerances are engineered to factory specifications, ensuring the cover seats flush with the gearbox without binding or rattling during high-speed runs or jumps. For serious RC enthusiasts running brushless motors with 8S LiPo power (as found in these high-performance X-Series vehicles), this upgrade provides tangible benefits in durability and appearance that justify the investment.

Frequently Asked Questions

• Which Traxxas X-Series models does this gear cover fit? — This cover is compatible with X-Maxx Ultimate, X-Maxx Belted 4WD Brushless RTR, XRT Ultimate, and XRT VXL-8S models. It fits all colour variants including red, green, orange, blue, and black models, making it a universal upgrade for the entire X-Series range.
• Is this aluminium gear cover durable for bashfield use? — Absolutely. The 6061-T6 aluminium is engineered for rigidity and toughness, and the anodised finish provides exceptional corrosion resistance and scratch protection. Whether you are bashing on rough UK terrain, sandy beaches, or muddy tracks, this cover will maintain its appearance and protective function through years of hard use.
• Will this upgrade improve my RC truck's performance? — Whilst this is primarily a protective and aesthetic upgrade rather than a performance-enhancing part, the rigid aluminium construction minimises gearbox flex, which can contribute to cleaner power delivery during acceleration and cornering. The lightweight design ensures no negative impact on overall vehicle dynamics or speed.
• How does this compare to other aftermarket gear covers? — Unlike third-party alternatives, this is a genuine Traxxas component manufactured to OEM specifications by the factory engineers who designed your X-Series vehicle. This guarantees perfect fit, superior material quality (6061-T6 aluminium), and the longevity of the anodised finish. Aftermarket covers may offer cost savings but often lack the precision engineering and durability of genuine Traxxas parts.
• Is installation difficult? — No, installation is straightforward and requires no modifications to your vehicle. The cover is engineered to factory tolerances, meaning it seats perfectly without adjustments. Simply position it over the gearbox and secure according to your vehicle's standard assembly procedure.
• What is the difference between anodised and painted finishes? — Anodising creates a hard, corrosion-resistant oxide layer integrated into the metal itself, whereas paint sits on the surface. Anodised finishes resist chipping, peeling, and oxidation far better than paint, especially in damp UK conditions and after exposure to dirt, salt, and UV light.
• Can I use this gear cover on other Traxxas models? — No, this cover is specifically engineered for X-Series vehicles (X-Maxx and XRT models). Traxxas manufactures different gear covers for other model ranges, so compatibility is limited to X-Series platforms.
