Key Features
- High-quality aluminium construction — This brace is precision manufactured from premium-grade aluminium, which provides an excellent strength-to-weight ratio, ensuring you get maximum structural support without adding unnecessary mass to your RC vehicle. Aluminium is the material of choice for competition-grade RC components because it offers superior rigidity compared to plastic whilst remaining significantly lighter than steel alternatives.
- Anodized ARRMA red finish — The anodized red coating serves both aesthetic and functional purposes. Aesthetically, it matches the distinctive ARRMA red branding and gives your vehicle a factory-built appearance. Functionally, the anodizing process hardens the aluminium surface, providing improved corrosion resistance and durability against the wear and tear of regular use and exposure to outdoor elements.
- High strength structural support — The rear center position of this brace is critical for maintaining chassis integrity during acceleration, braking and high-speed cornering. By reinforcing this area, you reduce chassis flex and improve overall handling precision, which is especially important when running brushless RC trucks and buggies capable of extreme speeds and acceleration.
- Laser-etched EXB logo — Beyond the visual appeal, the laser-etched logo demonstrates the precision manufacturing quality of this component. It's a detail that separates genuine ARRMA parts from lesser alternatives and serves as a mark of authenticity and professional engineering. This attention to detail is what you expect from a premium RC brand like ARRMA.
- Perfect fitment for ARRMA 6S models — This brace is engineered specifically for compatibility with ARRMA's 1/8 scale 6S brushless vehicles, including the KRATON 6S 4x4 range. The precise dimensions and mounting points ensure seamless integration without modification, making installation quick and straightforward for RC enthusiasts of any experience level.
Technical Performance
The Rear Center Aluminum Chassis Brace is engineered specifically for ARRMA's 1/8 scale 6S brushless platform, which includes high-performance models like the KRATON 6S 4x4 RTR brushless speed truck. At 140mm in length, this brace spans the critical rear-center section of the chassis where forces during acceleration, deceleration and lateral cornering are greatest. The precision-manufactured aluminium construction provides exceptional rigidity without the weight penalty of steel, making it an ideal upgrade for competitive drivers and weekend bashers alike. By reducing chassis flex in the rear section, this brace helps maintain consistent handling characteristics even when driving at high speeds or on challenging terrain. The anodized surface treatment hardens the aluminium, improving its resistance to corrosion and mechanical wear, which is essential for UK riders who may encounter wet conditions and variable weather. This is a genuine ARRMA component, manufactured to the same exacting standards as the complete vehicles, ensuring perfect integration with your existing setup.

Frequently Asked Questions
- Will this chassis brace improve my RC truck's handling and performance? — Yes, significantly. By reinforcing the rear-center section of your chassis, this brace reduces flex and improves structural rigidity. This translates to more consistent handling characteristics, especially during high-speed cornering, acceleration and heavy braking. If you're running a brushless RC truck and noticing any chassis flex or inconsistent handling, this is an excellent upgrade that will tighten up the overall feel of your vehicle.
- Is this suitable for beginners? — This is an optional chassis upgrade rather than a beginner-level component. However, installation is straightforward and requires only basic tools. If you're a beginner with an ARRMA 6S model and you're looking to enhance durability and performance, this is a worthwhile upgrade. It's not complex to fit, but it does assume you already have a complete ARRMA vehicle and some basic mechanical familiarity.
- What ARRMA models does this chassis brace fit? — This brace is designed for ARRMA's 1/8 scale 6S brushless vehicles, specifically including the KRATON 6S 4x4 range, which includes the RTR brushless speed truck, the roller versions and other variants in this platform. Always check your specific vehicle variant against the fitment list before ordering, though the 140mm rear center brace is a standard component for this model range.
- Will this brace work with my existing setup without modifications? — Yes. This is a genuine ARRMA component engineered for direct fitment with compatible models. No drilling, cutting or modification is required. The mounting points are already present on your chassis, making installation a simple bolt-on upgrade that any RC enthusiast can complete in minutes.
- Why is aluminium better than plastic for a chassis brace? — Aluminium offers several advantages: superior strength for a given weight, better rigidity to resist flex, improved corrosion resistance (especially when anodized as this brace is), and the ability to be precision-manufactured to extremely tight tolerances. For high-performance RC vehicles, aluminium chassis components are considered industry standard, particularly for brushless models that generate significant forces during acceleration and deceleration.
- How does this brace compare to the stock plastic equivalent? — The stock components on most ARRMA vehicles use reinforced plastic for weight savings and cost efficiency. This aluminium upgrade offers significantly greater rigidity and durability, particularly important if you drive at high speeds, bash aggressively, or compete regularly. The trade-off is a small increase in weight, but the performance and durability benefits typically outweigh this consideration for serious RC car enthusiasts.
