RPM Front Upper Lower A-Arms for ARRMA Kraton Talion Outcast Blue RPM81485

Overview

The RPM Front Upper & Lower A-Arms for ARRMA Kraton, Talion and Outcast represent a significant performance upgrade for RC enthusiasts in the UK looking to enhance their vehicle's handling and durability. These precision-engineered suspension components are designed with the same meticulous attention to detail that has made RPM a trusted name in the RC hobby. Whether you're a seasoned competitor pushing your RC monster truck to the limit or a weekend basher exploring the capabilities of your RC car, these A-arms deliver noticeable improvements in steering response, suspension geometry accuracy and overall reliability.

RPM has engineered these A-arms as a primary solution for strength and durability, but they've incorporated several advanced features that set them apart from stock components. The combination of reduced slop, alternative shock mounting positions and strategic weight reduction makes these arms an intelligent investment for anyone serious about their RC setup. Available in eye-catching blue, these suspension upgrades are compatible not only with ARRMA Kraton, Talion and Outcast models, but also with the Durango DEX8T, making them a versatile choice for various RC 4WD platforms.

RC Model Shop stocks genuine RPM components, backed by expert knowledge and a commitment to quality. These front A-arms are ready to replace your stock suspension geometry and unlock the full potential of your RC buggy or monster truck platform.

Key Features

• Slop Elimination Technology — These A-arms reduce the amount of movement at the inner mounts, providing significantly better steering response and more consistent camber, caster and toe angle settings throughout your driving session, which translates to more predictable handling characteristics and improved cornering performance.
• Dual Shock Mount Positions — The addition of a second shock mount hole further out on the arm enables a lower profile suspension set-up, allowing the shocks to lay down further and drop the ride height for a lower centre of gravity, improving weight distribution and handling dynamics.
• Weight Reduction — RPM front A-arms are roughly 10% lighter than stock components, weighing just 59.5g compared to 66g for original equipment, reducing unsprung weight and improving suspension response and overall vehicle agility.
• Chamfered Edge Design — Leading and trailing 30° chamfered edges provide smoother transitions over obstacles too tall for the suspension to clear, whilst also offering improved aerodynamics over stock components for enhanced high-speed stability.
• Engineering Grade Nylon Construction — All RPM A-arms are moulded from nearly indestructible engineering grade nylon, providing performance you can rely on in the worst conditions, whether you're bashing in wet terrain or racing at the track.
• Cross-Platform Compatibility — These arms fit ARRMA Kraton, Talion, Outcast and Durango DEX8T platforms, making them a valuable upgrade option across multiple RC 4WD vehicles in your collection.

Technical Performance

RPM has engineered these A-arms using a sophisticated blend of engineering grade nylons that deliver exceptional durability without compromising on performance. The 10% weight reduction compared to stock components—achieved through precision moulding and intelligent material selection—contributes to improved suspension responsiveness and reduced rotational inertia during directional changes. The slop elimination design works by minimising unwanted movement at the inner mount points, which is critical for maintaining consistent suspension geometry as you drive. This directly impacts your ability to maintain consistent camber, caster and toe angle settings, meaning your suspension tuning remains stable throughout your driving session rather than degrading as the suspension experiences wear and play. The dual shock mount hole design is a particularly clever engineering solution that allows experienced RC enthusiasts to fine-tune their suspension profile; the additional mounting position further out on the arm enables a geometry adjustment that lowers the ride height and centre of gravity without requiring additional components. The 30° chamfered edges are more than aesthetic; they provide a significant practical benefit by allowing smoother transitions over rough terrain and obstacles, whilst the aerodynamic profile of these edges contributes to improved high-speed stability. These A-arms replace ARRMA stock components AR330218 and AR330219, as well as Durango stock parts TD330709 and TD330710, making them a direct upgrade path for your existing RC vehicle.

Frequently Asked Questions

• Will these RPM A-arms fit my ARRMA RC vehicle? — Yes, these arms are specifically designed for ARRMA Kraton, Talion and Outcast models, and also fit the Durango DEX8T platform. They replace ARRMA stock parts AR330218 and AR330219. Always check your vehicle model before ordering.
• How much weight do these A-arms save compared to stock? — RPM front A-arms weigh 59.5g each, which is roughly 10% lighter than the stock components at 66g. This weight reduction improves suspension responsiveness and overall vehicle agility, particularly beneficial for competitive RC racing and high-speed bashing.
• What is slop elimination and why does it matter for my RC car? — Slop refers to unwanted movement and play in the suspension components at the inner mount points. RPM's design reduces this movement, which means your suspension geometry remains consistent throughout driving, providing better steering response and more predictable handling characteristics that are crucial for both track racing and competitive RC driving.
• How many A-arm packages do I need for my vehicle? — You need two packages for a complete front suspension upgrade, as each package contains one upper arm and one lower arm. This will fully replace both front A-arms on your RC vehicle.
• Can I use these A-arms with my existing shocks? — Yes, these A-arms are compatible with your existing shocks. The additional shock mount hole position allows for a lower profile suspension set-up if desired, but you can continue using your current shock setup with the standard mount position.
• Are RPM A-arms suitable for beginners? — Whilst RPM components are designed for durability and performance, A-arm replacement is a straightforward suspension upgrade suitable for any RC enthusiast. If you're comfortable with basic RC maintenance and have the necessary tools, installation should be manageable, though experienced drivers will benefit most from the performance improvements these components offer.
• What is the benefit of the chamfered edges? — The 30° chamfered edges on the leading and trailing surfaces provide smoother transitions over obstacles that exceed your suspension's travel limits, preventing sudden impacts that could damage components. Additionally, the aerodynamic profile of these edges improves high-speed stability compared to stock square-edged designs.
