Built by Fastrax, a recognised name in RC performance parts and accessories, this aluminium brace delivers the precision engineering and build quality that competitive and serious hobbyists expect. The use of high-grade aluminium ensures the component is lightweight yet rigid, maintaining suspension geometry accuracy without adding unnecessary weight that could affect handling. This component fits ARRMA vehicles including the KRA, OUT, SEN, and TYP model ranges, making it compatible with popular ready to run RC cars and upgradeable platforms. The black anodised finish not only looks professional but also provides enhanced corrosion resistance and durability, ensuring your investment remains protected through countless hours of driving.

RC enthusiasts across the UK rely on Fastrax upgrade parts to extend vehicle lifespan, improve performance consistency, and maintain competitive edge. If you've experienced suspension flex, worn upper arm mounting points, or want to reinforce your ARRMA platform for more aggressive driving, this rear aluminium brace is an essential upgrade that delivers measurable improvements in handling precision and longevity.

Key Features

• High-Grade Aluminium Construction — Manufactured from premium aluminium material that provides superior rigidity compared to plastic alternatives, ensuring suspension geometry remains consistent even under high-speed cornering, jumps, and aggressive driving that would cause flex in standard components.
• Rear Upper Arm Reinforcement — Specifically designed to brace the rear upper arm mounting points, which are stress points during hard acceleration, deceleration, and lateral forces, preventing suspension flex and maintaining predictable handling characteristics.
• Black Anodised Finish — The professional black anodised surface treatment provides excellent corrosion resistance, protects the aluminium from oxidation and weathering, and delivers a premium appearance that looks great on any ARRMA platform.
• Universal ARRMA Compatibility — Engineered to fit multiple ARRMA model ranges including KRA, OUT, SEN, and TYP platforms, offering broad compatibility across the ARRMA lineup for maximum value and flexibility.
• Direct Performance Upgrade — This component directly addresses suspension rigidity and durability, making it an ideal upgrade for drivers who want to improve handling precision, extend component lifespan, and reduce maintenance frequency on their RC vehicles.
• Lightweight Yet Rigid Design — The aluminium construction balances strength with minimal weight addition, ensuring you gain rigidity benefits without negatively affecting your vehicle's acceleration, braking, or overall performance characteristics.
• OEM Quality Part — As an official Fastrax product, this brace meets the same quality standards and engineering tolerances as manufacturer specifications, ensuring perfect fit and reliable performance on compatible ARRMA vehicles.

Technical Performance

The Fastrax rear aluminium brace represents a thoughtful engineering solution to a real-world problem experienced by ARRMA owners worldwide. The rear suspension, particularly the upper arm mounting points, experiences significant stress during cornering, acceleration, and deceleration cycles. Standard plastic components can gradually flex or deform under repeated stress, leading to geometry changes that affect handling predictability and increase wear on other suspension components. By upgrading to this aluminium brace, you eliminate flex at the critical rear upper arm mounting area, maintaining suspension geometry precision throughout extended driving sessions. The aluminium material is approximately three times more rigid than the plastic alternatives found on standard ARRMA vehicles, providing measurable improvements in handling response and corner entry precision. The black anodised finish adds a protective oxide layer that resists corrosion from moisture, salt spray, and UV exposure, ensuring your investment maintains its structural integrity and appearance for years of reliable service. This component represents the kind of incremental upgrade that transforms an RC car from a leisure toy into a performance platform worthy of competitive driving and serious hobbyist attention.

Frequently Asked Questions

• What ARRMA models does this rear aluminium brace fit? — This brace is compatible with ARRMA vehicles in the KRA, OUT, SEN, and TYP model ranges. Check your specific ARRMA model designation to confirm compatibility before ordering.
• Will this upgrade improve my ARRMA handling? — Yes, by eliminating flex at the rear upper arm mounting points, this aluminium brace provides noticeable improvements in suspension geometry consistency, leading to more predictable handling, better corner entry response, and improved overall vehicle control during aggressive driving.
• Is this a difficult part to install? — The installation complexity depends on your mechanical experience, but this is a direct replacement/upgrade component. Standard Allen keys and basic tools are typically required. Consult your ARRMA manual or Fastrax installation guide for detailed procedures.
• Why choose aluminium over plastic components? — Aluminium provides approximately three times greater rigidity than plastic, preventing suspension flex that would otherwise cause geometry changes and accelerated wear on other components. The rigidity directly translates to improved handling precision and extended component lifespan.
• Is this suitable for all driving styles? — This upgrade is particularly beneficial for aggressive bashers, high-speed drivers, and competitive RC enthusiasts who demand maximum handling precision and durability. Casual recreational drivers will also benefit from improved durability, though the performance gains may be less noticeable at lower speeds.
• Will this part require any other modifications? — This is a direct fit upgrade component designed specifically for ARRMA upper arm mounting points. No additional modifications are required, though some users pair it with other Fastrax performance upgrades for a comprehensive chassis reinforcement package.
• What is the black finish? — The finish is black anodised aluminium, which provides excellent protection against corrosion, oxidation, and UV damage while delivering a professional appearance. The anodised layer is harder than bare aluminium and resists chipping and scratching better than paint.
