Traxxas Weight, portal housing, brass (34 grams) (2 pcs) / 2.5x8 CS (6 pcs) (requires #8251X, 8251R, 8251A, or 8251G outer portal housing) TRX8267

Overview

The Traxxas Weight, portal housing, brass (34 grams) (2 pcs) / 2.5x8 CS (6 pcs) is an essential upgrade for serious RC crawler enthusiasts looking to fine-tune their vehicle's performance. Designed specifically for Traxxas TRX-4 models and compatible chassis, these brass portal housing weights deliver significant mass directly to the lowest point of your RC car, dramatically improving off-road stability and handling characteristics without the drawbacks associated with weighted wheels. Whether you're a competitive RC car racer in the UK, a weekend basher tackling challenging terrain, or someone discovering the depths of RC customisation for the first time, this weight upgrade represents a smart investment in your vehicle's capabilities.

Manufactured by Traxxas, a name synonymous with quality and innovation in the RC hobby, these brass weights are engineered with precision to work seamlessly with your existing TRX-4 setup. The low centre of gravity achieved through portal housing weight placement provides superior balance and traction, allowing your RC crawler to navigate obstacles with greater confidence and control. This is particularly valuable when you're running your RC car through challenging terrain or competing in organised events where stability and predictable handling can mean the difference between success and failure.

For anyone investing in a high-quality RC crawler, understanding the importance of weight distribution is crucial. These genuine Traxxas weights represent the manufacturer's own solution to this fundamental aspect of RC car tuning, ensuring compatibility and reliability that aftermarket solutions simply cannot guarantee.

Key Features

• Brass Construction — Made from quality brass material, these weights provide dense mass in a compact footprint, allowing you to add significant weight precisely where it matters most without increasing your vehicle's overall dimensions or creating unwanted weight distribution issues.
• 34-Gram Weight Per Pair — The substantial 34-gram mass of each weight unit gives you meaningful mass addition to your chassis setup, which translates directly into improved stability during off-road driving and better traction control on challenging surfaces.
• Low Centre of Gravity Design — Portal housing placement positions the weights at the lowest possible point on your RC crawler, creating a dramatically improved centre of gravity that enhances cornering stability, reduces body roll, and improves overall handling characteristics compared to other weight placement methods.
• Stability Without Wheel Weighting — Unlike weighted wheels, which can negatively impact acceleration, braking performance, and tyre wear patterns, these portal housing weights improve stability whilst maintaining the responsiveness and efficiency of your drivetrain and suspension system.
• Included Hardware — Each package includes six 2.5x8 mm stainless steel machine screws, providing secure fastening that eliminates the need to source additional fasteners, saving you time and ensuring you have everything needed for a complete installation.
• Genuine Traxxas Product — As an official Traxxas component, these weights are engineered to exact specifications and tested to work perfectly with compatible portal housing units, guaranteeing fitment and performance you simply cannot get with third-party alternatives.

Technical Performance

These brass portal housing weights represent the culmination of Traxxas's extensive experience in RC vehicle engineering and chassis tuning. The material choice of brass is deliberate—brass offers superior density compared to aluminium or steel alternatives, allowing significant mass to be added in a compact volume. This density advantage means you get meaningful weight reduction in vehicle dimensions, critical when space inside portal housings is at a premium. The 34-gram weight per piece is precisely calculated to provide noticeable stability improvements without creating excessive strain on your suspension components, motor, or battery. The engineering principle is straightforward: by lowering your vehicle's centre of gravity through portal housing weight placement, you create a more stable platform that resists tipping during aggressive cornering, climbing obstacles, and navigating uneven terrain. The included 2.5x8 mm stainless steel fasteners are designed to withstand the vibration and stress of off-road RC driving, ensuring your weights remain securely fastened through countless sessions. This level of attention to detail—from material selection through to hardware specification—is what distinguishes genuine Traxxas components from aftermarket alternatives and explains why serious RC enthusiasts across the UK specify Traxxas upgrades for their vehicles.
