Traxxas Motor Mount Washers Aluminium Red-Anodised 4x18mm BCS TRX7759R

Overview

The Traxxas Washers, motor mount, aluminium (Red-anodised) (4)/ 4x18mm BCS (4) TRX7759R are essential upgrade components for Traxxas X-Maxx and XRT RC monster truck enthusiasts looking to enhance both the performance and aesthetics of their vehicles. These specially engineered aluminium washers are designed to add additional strength and durability to the motor mount assemblies in the X-Maxx chassis, making them a perfect choice for serious RC car UK hobbyists who demand reliability and visual appeal. Whether you're upgrading an existing X-Maxx or XRT, or restoring a well-used machine, these red-anodised washers deliver the quality and attention to detail that Traxxas is renowned for.

This is a pack of four optional motor mount washers that provide genuine replacement and accessory compatibility across the entire X-Maxx and XRT range, including the Ultimate variants and various colour options. The red-anodised finish not only looks stunning but also provides corrosion resistance, ensuring your investment maintains its appearance and integrity through countless bashing sessions. For UK RC enthusiasts who take pride in their machines, these washers represent the perfect combination of form and function, reinforcing the motor mount area where stress and vibration are most concentrated during aggressive driving.

Traxxas has engineered these washers to precise specifications, ensuring they integrate seamlessly with your existing X-Maxx or XRT chassis without requiring modification. The anodised aluminium construction means they're lightweight yet incredibly strong, adding strength where it matters most without compromising the overall balance and performance of your brushless RC monster truck. Whether you're running your machine on gravel, tarmac, or grass, these washers will help maintain the integrity of your motor mounts for years to come.

Key Features

• Red-anodised aluminium construction — The bright red finish not only looks fantastic and matches the aggressive styling of modern X-Maxx and XRT builds, but the anodising process also provides a protective oxide layer that resists corrosion and oxidation, ensuring the washers maintain their appearance and integrity even after exposure to water and extreme weather conditions.
• Pack of four washers — This pack includes four individual washers, providing complete coverage for your motor mount assembly and ensuring you have spare components for future maintenance or multiple build projects without needing to purchase additional packs.
• 4x18mm BCS specification — These washers are engineered to the exact 4x18mm Ball Cup Socket specification, ensuring perfect fit and alignment with your X-Maxx or XRT motor mount hardware without any guesswork or modification required.
• Enhanced motor mount strength — By distributing loads across a larger surface area, these washers reduce stress concentration on individual fastening points, which is especially important in high-powered brushless RC applications where motor vibration and torque forces are significant.
• Direct replacement and accessory part — These washers are recognised as genuine replacement parts for X-Maxx Ultimate and XRT Ultimate models, and are official accessory upgrades for standard X-Maxx and XRT variants, meaning you're getting Traxxas-engineered components that are guaranteed compatible with your vehicle.
• Lightweight yet durable — Aluminium provides an ideal strength-to-weight ratio, meaning you gain structural reinforcement without adding unnecessary mass that could affect your RC monster truck's acceleration, handling, or battery runtime.

Technical Performance

These motor mount washers are engineered from high-grade aluminium and finished with red anodising, a process that converts the aluminium surface into a durable, corrosion-resistant oxide layer. The 4x18mm BCS (Ball Cup Socket) specification indicates these washers are designed to interface with the standard motor mount fastening system found on Traxxas brushless RC monster trucks. The anodising process not only provides aesthetic appeal but also offers practical benefits including improved wear resistance and enhanced durability in wet conditions commonly encountered during UK RC bashing sessions. The washers work by distributing the clamping force from the fastener across a wider surface area, which reduces pressure concentration and helps prevent damage to the plastic or composite components of the motor mount. In a high-performance 8S brushless RC monster truck like the X-Maxx with its substantial torque output, proper motor mount integrity is crucial for maintaining component longevity and consistent performance. These aluminium washers are significantly stronger than standard plastic washers and provide superior vibration damping characteristics, which contributes to improved component lifespan and more consistent handling characteristics during rapid acceleration and deceleration. The red-anodised finish is particularly popular in the competitive RC community as it provides a professional, finished appearance that complements modern X-Maxx and XRT bodywork whilst maintaining its appearance through exposure to dirt, mud, water, and UV radiation.

Frequently Asked Questions

• Which Traxxas RC models are these motor mount washers compatible with? — These TRX7759R washers are genuine replacement parts for the X-Maxx Ultimate and XRT Ultimate models, and are official accessory parts for the X-Maxx and XRT ranges. Specific compatible vehicles include the X-Maxx Belted 4WD Brushless RTR 8S Monster Truck (available in Orange, Blue, Red, and Green variants), X-Maxx Ultimate models, X-Monster Chassis, XRT VXL-8S models in Green, Black, Blue, and Orange, and XRT Ultimate variants, making them suitable for a wide range of Traxxas monster truck enthusiasts across the UK.
• Will these washers work on other Traxxas models? — These washers are specifically engineered for the X-Maxx and XRT chassis families. Whilst they feature the standard 4x18mm BCS specification found on many Traxxas vehicles, compatibility is guaranteed only with the models listed. If you own a different Traxxas model, we recommend checking your manual or contacting our expert team at RC Model Shop to confirm compatibility before purchasing.
• What is the benefit of upgrading to aluminium washers? — Aluminium washers provide several advantages over standard plastic washers: they distribute clamping force more effectively across a wider surface area, they resist corrosion and maintain their appearance longer, they provide superior vibration damping characteristics which can improve component lifespan, and they deliver a more professional, finished appearance to your build. For owners of expensive 8S brushless RC monster trucks like the X-Maxx, the modest investment in quality washers can help protect your motor mounts from premature wear and damage.
• Why is the anodising finish important? — The red-anodised finish serves both aesthetic and functional purposes. Functionally, the anodising process creates a hard, corrosion-resistant oxide layer that protects the underlying aluminium from oxidation, particularly important when your RC monster truck is exposed to water, mud, and moisture during UK bashing sessions. Aesthetically, the bright red finish looks stunning and complements modern X-Maxx and XRT styling, providing a professional, finished appearance that reflects the quality of your complete build.
• Are these genuine Traxxas parts? — Yes, part number TRX7759R is an official Traxxas genuine spare part, manufactured to Traxxas specifications and quality standards. When you purchase from RC Model Shop, you're guaranteed authentic components with full compatibility assurance and the peace of mind that comes from using manufacturer-approved parts in your RC vehicle.
• How many washers do I need? — This pack contains four washers, which is the standard quantity required to fully upgrade the motor mount assembly in a single X-Maxx or XRT vehicle. Each washer in the set is identical, allowing for complete uniform coverage of the motor mounting points.
• Can I use these washers as replacements for damaged components? — Absolutely. If your existing motor mount washers have become damaged, cracked, or corroded, these replacements will restore your motor mount to its original specification and performance characteristics. They're recognised as genuine replacement parts for X-Maxx Ultimate and XRT Ultimate models.
• Will these washers affect my vehicle's performance? — These washers will not negatively impact performance. In fact, by improving motor mount rigidity and stability, they may enhance your RC monster truck's consistency and handling characteristics during rapid acceleration and deceleration. The minimal weight addition is negligible on a vehicle of this scale and power.
