Overview

The Fastrax Arrma Aluminium Short Brace Rear for the 1/8 Kraton EXB 6S is an essential upgrade component designed to enhance the durability and performance of your high-powered RC buggy. Whether you're a seasoned RC enthusiast running a brushless 1/8 scale RC car or looking to reinforce your Kraton's chassis after intensive bashing sessions, this premium aluminium brace delivers the structural support needed to keep your vehicle performing at its best. Built by Fastrax, a recognised brand in the RC hobby community, this rear brace is engineered specifically for the demanding requirements of 6S LiPo-powered buggies, where chassis flex and component stress are critical concerns. As part of the growing ecosystem of RC tune-up options available in the UK, this component represents a smart investment in longevity and reliability.

The Kraton EXB 6S is one of ARRMA's most powerful and explosive off-road buggies, capable of extreme speeds and intense acceleration thanks to its brushless motor and 6S LiPo battery system. However, the sheer power generated at these performance levels places enormous stress on the chassis and suspension mounting points. This is where the Fastrax aluminium short brace becomes invaluable. By reinforcing the rear of the chassis, it helps to minimise flex during hard cornering, acceleration and deceleration, translating directly into improved handling, better weight distribution and extended component life. For RC car owners in the UK who demand performance and reliability in equal measure, this upgrade is a sensible choice that will keep your investment running stronger for longer.

Available in a striking red finish that complements the Kraton's aggressive styling, this short brace combines form with function. It's the kind of upgrade that experienced RC bashers and competition drivers reach for when they're serious about protecting their investment and maximising performance. Whether you're hitting the track, conquering rough terrain, or simply enjoying weekend recreational bashing, having quality tune-up components like this one makes all the difference between a vehicle that lasts and one that keeps breaking down.

Key Features

• Premium Aluminium Construction — Manufactured from high-grade aluminium alloy, this rear brace combines lightweight properties with exceptional rigidity and strength, ensuring minimal flex while avoiding unnecessary weight addition that could compromise acceleration and handling characteristics.
• Purpose-Built for Kraton EXB 6S — This component is specifically engineered and tested for compatibility with the Arrma Kraton EXB 6S platform, guaranteeing perfect fitment and optimal performance enhancement without modification or adaptation.
• Short Brace Design — The short brace configuration provides targeted reinforcement of the rear chassis area, addressing the stress points most affected by high-power 6S LiPo acceleration and cornering loads without adding excessive bulk or complexity.
• Enhanced Chassis Rigidity — By reducing chassis flex during aggressive driving, this brace improves suspension geometry consistency, leading to more predictable handling, better traction control and improved overall drivability across various terrain types.
• Protective Component Mounting — The brace helps stabilise and protect critical rear-end components including the transmission, suspension mounts and electronics, reducing stress fractures and extending the lifespan of expensive drivetrain parts.
• Competition-Grade Quality — Fastrax components are trusted by RC enthusiasts and competitive drivers throughout the UK and beyond, recognised for their engineering precision and contribution to vehicle reliability and performance.
• Easy Installation — As a direct fitment brace, installation is straightforward for anyone with basic RC knowledge, requiring standard tools and taking minimal time to install without requiring extensive chassis modification.
• Distinctive Red Finish — The vibrant red colour scheme enhances the visual appeal of your Kraton whilst providing excellent visibility during outdoor driving sessions, making your vehicle easier to track during high-speed manoeuvres.

Technical Performance

The Fastrax Arrma Aluminium Short Brace Rear represents engineering excellence in chassis reinforcement design. Constructed from precision-machined aluminium alloy, it delivers the rigidity needed to handle the immense forces generated by the Kraton EXB 6S's brushless motor system and 6S LiPo power delivery. The Kraton EXB 6S is capable of tremendous acceleration and speed, powered by a brushless system that generates substantially more torque and power than conventional brushed motors, making chassis reinforcement essential for reliability. This short brace specifically targets the rear end of the chassis, where suspension mounting points, transmission components and shock tower connections experience the highest stress loads during cornering, acceleration and deceleration cycles. By minimising chassis flex in this critical area, the brace ensures that suspension geometry remains consistent throughout driving conditions, improving traction and handling precision. The aluminium material choice is particularly strategic: it provides exceptional strength-to-weight ratio, meaning the performance gains from increased rigidity are not offset by significant additional mass that would reduce acceleration and speed. For RC enthusiasts in the UK who run demanding 6S LiPo systems and push their vehicles to the limits, this component is engineered to last and perform. The direct fitment design means no modifications or adaptations are required, allowing riders to install the brace and immediately experience the benefits of improved chassis stiffness and component protection.

Frequently Asked Questions

• Is the Fastrax Arrma aluminium short brace essential for my Kraton EXB 6S? — Whilst the Kraton EXB 6S will function without this brace, adding rear chassis reinforcement is highly recommended if you run 6S LiPo power regularly or engage in aggressive driving. The 6S system generates substantial power and torque that place stress on the chassis, and this brace significantly reduces flex and component fatigue, extending the vehicle's operational lifespan and improving reliability between service intervals.
• What is the difference between a short brace and full-length chassis brace? — A short brace provides targeted reinforcement to the rear chassis area specifically, where suspension mounts and transmission components experience the greatest stress. This approach minimises added weight whilst addressing the primary flex points. A full-length brace would reinforce the entire chassis length but adds more overall mass, which can slightly reduce acceleration. The short brace design offers the optimal balance for most drivers.
• Will this brace fit other ARRMA models? — No, this brace is specifically engineered and tested for the Kraton EXB 6S platform. Whilst other ARRMA buggies may have similar chassis designs, attempting to fit this component to alternative models could result in fitment issues or compatibility problems. Always verify that tune-up components are designed for your specific vehicle platform.
• How difficult is installation? — Installation is straightforward for anyone with basic RC maintenance experience. The brace uses standard fasteners and mounting points already present on your Kraton EXB 6S, requiring only common hand tools and approximately 15-20 minutes of work. No permanent modifications to the chassis are necessary.
• Can I use this brace with 3S or 4S LiPo batteries? — Whilst this brace is specifically rated and engineered for 6S LiPo systems, it will technically fit and function with lower voltage LiPo systems such as 3S or 4S. However, the primary benefit of chassis reinforcement becomes less critical with lower power outputs, as the stress loads on the chassis are proportionally reduced. The brace is optimally engineered for 6S performance.
• What material is this brace made from? — This component is manufactured from high-grade aluminium alloy, selected for its exceptional strength-to-weight ratio. Aluminium provides outstanding rigidity and durability whilst keeping weight addition minimal, ensuring that performance improvements from reduced chassis flex are not negated by additional mass.
• Does this brace improve handling? — Yes, by reducing rear chassis flex during cornering and acceleration, this brace helps maintain consistent suspension geometry. This directly translates to improved traction, more predictable handling characteristics and better overall control during aggressive driving manoeuvres, particularly noticeable on rough or uneven terrain.
