Overview
The Traxxas Washers, motor mount, steel (4), 4x18mm BCS (4) TRX7759-BLK is an essential upgrade component for owners of high-performance Traxxas RC models, particularly the X-Maxx and XRT series. If you're serious about maintaining your RC car UK setup and want to enhance both the durability and appearance of your motor mount assembly, this genuine Traxxas spare part delivers exactly what you need. These precision-engineered washers are specifically designed to reinforce the motor mount connection points, ensuring your brushless RC monster truck or truggy remains stable and secure during intense driving sessions.
Whether you're a seasoned RC enthusiast running a ready to run RC truck at the track or a weekend basher pushing your vehicle to its limits off-road, the integrity of your motor mount is absolutely critical. Motor mounts endure tremendous stress from the power output of modern brushless motors, and having quality washers in place means the difference between reliable performance and potential component failure. This genuine Traxxas product ensures perfect compatibility with your specific RC model and maintains the exact tolerances Traxxas engineers designed into your chassis.
The included 4x18mm socket cap screws (4) work in perfect harmony with these washers to create a secure, professional-grade fastening solution. By upgrading to these aluminium washers, you're not just improving structural integrity—you're also adding visual appeal to your motor mount area, giving your RC off-road truck or monster truck a more refined, quality appearance that reflects the care you invest in your hobby.
Key Features
- Steel Washers (Quantity: 4) — These durable steel washers provide additional load distribution and structural reinforcement for the motor mount connection points, helping to prevent fastener loosening and damage to the chassis material during aggressive driving or high-performance racing of your brushless RC car.
- 4x18mm Socket Cap Screws (Quantity: 4) — High-quality socket cap screws are included to work seamlessly with the washers, offering secure fastening that meets Traxxas specifications and maintains the professional appearance of your motor mount assembly on ready to run RC models.
- Genuine Traxxas Component — As an official Traxxas spare part, this product guarantees perfect fitment and performance on compatible vehicles, ensuring you're installing genuine components designed by the manufacturer specifically for your RC truck or buggy.
- Enhanced Durability — The addition of washers increases the contact surface area between fasteners and the chassis material, distributing stress more evenly and reducing the risk of fastener pull-through or component damage during intense RC driving sessions.
- Professional Aesthetics — Beyond functionality, these washers add a refined, quality appearance to the motor mount area of your RC model, enhancing the overall presentation of your investment and showing attention to detail in your setup.

Technical Performance
The Traxxas motor mount washer system represents precision engineering focused on reinforcing one of the most critical connection points in any high-performance RC vehicle. These steel washers are manufactured to exact specifications that match the original Traxxas design requirements, ensuring they work perfectly with the included 4x18mm socket cap screws. The material composition of steel provides excellent strength-to-weight ratio and superior durability compared to plastic or thin metal alternatives, making these washers ideal for the demanding environment of brushless RC cars. When installed properly, the washer assembly distributes the clamping force evenly across a larger surface area, which is essential when dealing with the torque and vibration generated by modern brushless motors in 1/10 scale and larger RC trucks. The socket cap screw design offers several advantages over standard fasteners: the hex socket provides superior grip and reduced risk of stripping, the flat top ensures a clean, professional appearance, and the specific 4x18mm dimensions are engineered to match perfectly with X-Maxx and XRT motor mount boss holes and thickness tolerances. This attention to material selection and dimensional accuracy ensures that your motor mount fastening system can handle the sustained power output of 8S LiPo configurations and the shock loads associated with jump landings and rough terrain navigation typical of serious RC off-road driving and racing.

Frequently Asked Questions
- What is the purpose of motor mount washers on RC trucks and buggies? — Motor mount washers serve a critical function in distributing the clamping load from fasteners across a wider surface area. This prevents the screw head from pulling through softer chassis materials and helps maintain secure connections even under the vibration and stress generated by powerful brushless motors. When driving high-performance RC vehicles like the X-Maxx or XRT, upgrading to quality washers is a smart maintenance and reliability upgrade.
- Are these washers compatible with my Traxxas model? — These washers are specifically engineered for Traxxas X-Maxx series models including the X-Maxx Belted 4WD in orange, blue, red, and green variants, the X-Maxx Ultimate in blue and green, and the XRT VXL-8S series in multiple colours, as well as the XRT Ultimate models. Check your model number against the compatibility list to confirm fitment before purchasing your RC spares.
- Can I use these washers to repair or maintain my existing motor mount? — Absolutely. These genuine Traxxas washers are supplied as replacement spares specifically for maintaining the motor mount assembly on compatible vehicles. If you've experienced loosening or damage to your motor mount fasteners, upgrading to these washers alongside new socket cap screws is an excellent way to restore and improve the integrity of this critical connection point on your RC model.
- What makes steel washers better than plastic or aluminium alternatives? — Steel offers superior strength, durability, and resistance to deformation under sustained load compared to plastic washers. Whilst aluminium can provide adequate performance, steel is the material of choice for load-bearing applications in high-stress environments like RC motor mounts. The investment in quality steel washers pays dividends in reliability and longevity, especially when running powerful brushless RC configurations.
- Do I need any special tools to install these washers? — Installation is straightforward and requires only a hex key (Allen key) that matches the 4x18mm socket cap screw dimensions. You'll need to remove the existing motor mount fasteners, slide the new washers onto the screws, position them in the motor mount holes, and tighten securely. Standard RC maintenance tools are all that's required.
