Z-ARA320757

Overview

The ARRMA Rear Brace and Wing Bracket Z-ARA320757 is a premium upgrade component designed specifically for high-performance RC monster trucks and stunt vehicles. This genuine ARRMA part delivers the strength and precision engineering that competitive RC enthusiasts and casual bashers alike demand from their RC car UK setups. Whether you're running a brushless speed truck at maximum velocity or pushing your RC vehicle through aggressive terrain, this rear brace mount ensures your chassis maintains structural integrity and alignment under extreme stress.

Built by GPM Racing using aerospace-grade 7075-T6 aluminium alloy, this component represents a significant performance upgrade over standard plastic alternatives. The engineering behind this part focuses on combining exceptional strength with lightweight construction, ensuring your brushless RC monster truck maintains optimal handling characteristics without sacrificing durability. This is the kind of upgrade that separates weekend bashers from serious RC enthusiasts who understand that chassis rigidity directly translates to better cornering, more predictable handling, and increased longevity of your investment.

Available in eye-catching red anodised finish, this rear centre brace mount is compatible with multiple ARRMA 1/8 scale platforms including the Kraton 6S EXB, Kraton 6S V6, and the Notorious 6S V6 stunt truck. Whether you're operating your ready to run RC truck on tarmac, grass, or rough terrain, this upgrade component delivers the chassis support needed to keep your vehicle performing at its peak.

Key Features

• 7075-T6 Aerospace-Grade Aluminium Alloy Construction — This premium material specification combines exceptional strength-to-weight ratio, providing long-lasting stability and durability that dramatically outlasts standard composite materials, making it ideal for high-performance RC car UK applications where reliability matters.
• Multi-Colour Anodised Finish — The red anodised surface treatment not only provides corrosion resistance and aesthetic personalisation for your RC vehicle, but also indicates the premium nature of the component, allowing enthusiasts to create visually striking and unique custom builds.
• Precision Engineered for ARRMA Compatibility — Every dimension and mounting point has been calculated to achieve a perfect fit with ARRMA 1/8 scale monsters trucks and stunt vehicles, ensuring safe and secure mounting in all driving conditions without modification.
• Increased Chassis Rigidity — By reinforcing the rear centre section of your RC monster truck chassis, this brace mount reduces flex during aggressive acceleration, cornering, and landing after jumps, directly improving handling precision and responsiveness.
• Grade 12.9 Steel Cap Head Screws Included — High-tensile fasteners are provided as standard, offering superior corrosion resistance and reliability compared to standard hardware, ensuring your upgrade remains secure through countless hours of RC action.
• Lightweight Design — Unlike heavier steel alternatives, the aluminium construction keeps unsprung weight to an absolute minimum, preserving your RC truck's suspension geometry and overall performance characteristics.
• Crash-Resistant Performance — The robust construction provides enhanced protection against chassis cracking and warping during impacts, extending the service life of your brushless RC speed truck even during intense bashing sessions.

Technical Performance

This rear centre brace mount represents cutting-edge engineering in RC chassis reinforcement. Manufactured from 7075-T6 aluminium alloy—the same material specification used in aerospace and high-performance racing applications—the component delivers uncompromising strength without the weight penalty of steel alternatives. The precise engineering ensures compatibility across the entire ARRMA 1/8 brushless RC monster truck platform, including the Kraton 6S EXB (model ARA8708V6 and ARA8708T1) and the Kraton 6S V6 (model ARA8608V6), as well as the Notorious 6S V6 stunt truck (model ARA8611V6). The anodised surface treatment provides both aesthetic appeal and corrosion resistance, whilst the pre-assembled mounting points require only the inclusion of Grade 12.9 black cap head screws (3x10mm) for installation. Installation is straightforward for experienced RC enthusiasts, though ARRMA recommends applying thread-locking compound to the fasteners to prevent vibration-induced loosening during high-speed operation. The component directly addresses one of the most common failure points in high-performance RC trucks—rear chassis flex during aggressive cornering and acceleration—making it an essential upgrade for anyone running their brushless RC vehicle at the limit of its performance envelope.

Frequently Asked Questions

• Which ARRMA RC trucks is this rear brace mount compatible with? — This component is designed for ARRMA 1/8 scale brushless vehicles including the Kraton 6S EXB (ARA8708V6 and ARA8708T1), Kraton 6S V6 (ARA8608V6 available in Black, Pink, Blue, Orange, and Green colour variants), and the Notorious 6S V6 stunt truck (ARA8611V6 available in Black and Blue). Check your specific model number to confirm compatibility before ordering.
• Is this a direct replacement part for my ARRMA RC monster truck? — Yes, this is a genuine ARRMA component (original part number ARA320757) engineered as a direct fit replacement. All mounting points, dimensions, and fastener specifications have been precision-calculated for your specific ARRMA platform.
• Will this upgrade improve my RC truck's performance? — Absolutely. By reinforcing the rear centre section of your chassis, this brace mount reduces flex during acceleration and cornering, resulting in more predictable handling, better weight distribution, and improved overall responsiveness from your brushless RC vehicle. Users typically notice improved cornering precision and reduced chassis twist during jumps.
• What makes 7075-T6 aluminium better than standard plastic? — 7075-T6 aluminium offers approximately 5-10 times greater stiffness than standard composite materials whilst maintaining a lighter overall weight than steel. This superior strength-to-weight ratio means your RC truck maintains precise handling characteristics whilst resisting the cracking and warping that affects plastic components under extreme stress.
• Do I need any special tools to install this component? — Installation requires only standard hexagon key tools compatible with the cap head screws provided. No special tools, welding, or modifications are necessary. ARRMA recommends using thread-locking compound on the fasteners to prevent loosening from vibration during high-speed operation.
• Will this fit my coloured variant of the Kraton or Notorious? — Yes. This rear centre brace mount is compatible across all colour variants of compatible ARRMA models. The red anodised finish of this component provides an attractive contrast with any ARRMA body colour.
• What is the difference between this GPM Racing upgrade and the original ARRMA plastic component? — The original ARRMA component is typically manufactured from reinforced composite material, whilst this GPM Racing upgrade uses aerospace-grade 7075-T6 aluminium alloy. The aluminium version offers superior rigidity, better corrosion resistance through anodised surface treatment, and increased durability under extreme conditions, making it the preferred choice for serious RC enthusiasts and competitive drivers.
• Is this suitable for beginner RC users? — Whilst this component is technically suitable for any ARRMA 1/8 owner, it represents an intermediate-to-advanced upgrade best appreciated by drivers familiar with chassis tuning and performance optimisation. Beginners can certainly install it without difficulty, but will benefit most from understanding how chassis rigidity affects vehicle handling characteristics.
