Traxxas Aluminium Motor Mount Washers Grey-Anodised 4 Pack TRX7759-GRAY

Overview

The Traxxas Washers, motor mount, aluminium (Grey-anodised) (4 pcs) / 4x18mm BCS (4 pcs) TRX7759-GRAY represents a premium upgrade option for serious RC enthusiasts running Traxxas X-Maxx and XRT platform vehicles. These specially engineered aluminium washers are designed to add additional strength and durability to your motor mounts whilst delivering an attractive grey-anodised finish that complements modern RC car UK builds. Whether you're upgrading a stock Traxxas X-Maxx Belted 4WD Brushless RTR monster truck or pushing the performance envelope with high-output brushless systems, these washers provide the structural reinforcement needed for long-term reliability during intense off-road action.

Motor mounts experience significant stress during acceleration, cornering and landing impacts, particularly on high-powered brushless RC vehicles. Standard plastic or basic metal components can flex or wear over time, compromising precision and alignment. By installing these genuine Traxxas aluminium motor mount washers, you're investing in the kind of chassis upgrades that separate weekend bashers from serious competitors. The grey-anodised finish isn't just cosmetic—hard-anodising provides corrosion resistance and surface durability, ensuring your upgrade maintains its appearance and protective properties through countless hours of driving.

These washers are part of Traxxas's comprehensive upgrade ecosystem, which allows you to progressively enhance your RC monster truck's performance, durability and aesthetics through phase-based improvements. Whether you're already running an upgraded suspension with heavy-duty arms and aluminium chassis components, or you're planning your next round of modifications, these motor mount washers represent a targeted precision upgrade that delivers both functional and visual benefits to your X-Maxx or XRT platform vehicle.

Key Features

• Premium Aluminium Construction — Manufactured from high-quality aluminium material, these washers provide superior strength-to-weight characteristics compared to plastic alternatives, ensuring your motor mounts remain rigid and properly aligned even under the extreme loads generated by brushless power systems.
• Grey-Anodised Finish — The hard-anodised grey coating offers exceptional corrosion resistance and durability, protecting against moisture, salt spray and UV degradation whilst maintaining a professional appearance that matches modern RC car aesthetics and coordinates with contemporary Traxxas colour schemes.
• Direct Replacement Design — These washers are engineered as bolt-on upgrades for Traxxas X-Maxx and XRT vehicles, requiring no modification to your existing chassis or motor mount components, making installation straightforward for anyone with basic RC maintenance knowledge.
• Improved Motor Mount Integrity — By distributing fastener loads more evenly across the motor mount surface, these aluminium washers reduce stress concentration and prevent the flexing or creeping that can occur with plastic components, maintaining precise motor alignment for optimal power transmission and acceleration response.
• Four-Piece Pack — The set includes four washers, providing complete coverage for motor mount fastening points on your Traxxas X-Maxx or XRT, with 4x18mm BCS (Bearing Cap Screws) specifications for compatibility with Traxxas motor mount systems.
• Upgrade Ecosystem Compatibility — These washers form part of Traxxas's modular upgrade programme, allowing you to combine them with other Phase 2 and Phase 3 enhancements including aluminium suspension blocks, big bore shocks, and brushless power systems for comprehensive performance maximisation.
• Enhanced Durability Path — Particularly beneficial if you've already upgraded to heavy-duty suspension arms or are planning a brushless power-up, these washers ensure your motor mounts can reliably handle the increased stress and rigidity of a fully upgraded chassis.

Technical Performance

The Traxxas TRX7759-GRAY motor mount washers are engineered specifically for the X-Maxx platform, which represents the company's flagship 4WD brushless monster truck capable of 60+mph performance when equipped with Velineon VXL-3s brushless systems and appropriate gearing. Motor mounts in this class of vehicle must withstand extreme forces—the combination of a powerful brushless motor, high-torque transmission, and rough terrain impacts places significant stress on fastener points and mounting surfaces. By upgrading from plastic to hard-anodised aluminium, you're dramatically improving the structural integrity and fatigue resistance of these critical components. The 4x18mm BCS fastener specification ensures compatibility with genuine Traxxas motor mount designs, whilst the hard-anodising process creates a surface layer measuring several thousandths of an inch thick, providing both corrosion protection and increased wear resistance. This is particularly important for UK RC enthusiasts who operate vehicles in varying weather conditions, where moisture exposure can degrade unprotected materials. The grey colour finish provides aesthetic appeal whilst the anodising process ensures the coating bonds metallurgically to the aluminium substrate, preventing peeling or flaking even after thousands of fastening cycles. When combined with other Phase 2 upgrades such as aluminium steering blocks, caster blocks, and rear uprights, these motor mount washers contribute to a cohesive improvement in chassis rigidity and precision that directly translates to more responsive handling and improved durability during intense off-road driving sessions.

Frequently Asked Questions

• Which Traxxas models are these motor mount washers compatible with? — These TRX7759-GRAY washers are designed for Traxxas X-Maxx and XRT platform vehicles, including the X-Maxx Belted 4WD Brushless RTR in red, green, orange and blue colour options, the X-Maxx Ultimate models, and the XRT VXL-8S and XRT Ultimate variants. They work with all X-Maxx and XRT chassis regardless of the body colour or specific sub-model variant.
• Do I need special tools to install these motor mount washers? — Installation is straightforward and can be completed with basic RC maintenance tools. The Traxxas 8712 tool kit includes premium hex bits and nut drivers suitable for this work, though standard metric hex keys and a small Phillips screwdriver may be sufficient depending on your motor mount fastener configuration.
• What is the advantage of aluminium motor mount washers over the stock plastic components? — Aluminium washers provide significantly greater rigidity, strength and durability compared to plastic. They distribute fastener loads more evenly, prevent flexing and creeping under motor stress, maintain precise motor alignment for optimal power delivery, and resist corrosion and UV degradation much more effectively, particularly in varying UK weather conditions.
• Are these washers suitable for high-performance brushless setups? — Yes, these aluminium motor mount washers are particularly recommended if you're running or planning to run Velineon brushless systems such as the VXL-3s power system on your X-Maxx or XRT. Brushless motors generate significantly more power and torque than brushed alternatives, placing greater stress on motor mounts, making quality aluminium components essential for reliability.
• What does hard-anodised grey finish mean? — Hard-anodising is an electrochemical process that creates a protective oxide layer on the aluminium surface. This coating provides excellent corrosion resistance, increases surface hardness to resist scratches and wear, and creates a durable finish that resists peeling or flaking. The grey colour provides a modern aesthetic whilst being more forgiving of minor marks than brighter anodised colours.
• Can these washers be used as part of a Phase 2 upgrade programme? — Whilst the manufacturer's Phase 2 upgrade focuses on aluminium steering blocks, caster blocks, bellcranks, rear uprights and servo upgrades, these motor mount washers complement Phase 2 modifications perfectly by ensuring your motor mounts are equally robust and durable as your other upgraded components.
• How many washers come in the pack? — The pack contains 4 aluminium motor mount washers plus 4x 4x18mm BCS fasteners, providing complete coverage for a full motor mount fastening setup on your Traxxas X-Maxx or XRT platform vehicle.
