Technical Performance

These Fastrax ARRMA Rear Aluminium Lower Suspension Arms represent a meaningful upgrade to your vehicle's suspension architecture. The use of aluminium as the primary construction material delivers several performance advantages over stock plastic components. Aluminium offers superior rigidity and strength-to-weight characteristics, which translates into improved suspension response and more consistent handling during aggressive driving. The arms are precision-manufactured to ensure accurate geometry that maintains proper suspension angles and prevents unwanted deflection under cornering loads or impact forces. When you're running your ARRMA Kraton or OutCast through challenging terrain, rock gardens, or competitive racing courses, these reinforced suspension arms provide the structural integrity needed to keep your vehicle performing consistently. The engineering behind these components means they're less susceptible to the bending and flexing that often occurs with plastic arms during high-speed manoeuvres or heavy landings. By upgrading to these aluminium arms, you're investing in longevity and reliability—components that will continue to perform perfectly lap after lap, bash after bash, without the degradation that plastic arms typically experience over extended use.

Frequently Asked Questions

• Will these Fastrax rear aluminium suspension arms fit my ARRMA Kraton or OutCast? — Yes, these arms are specifically engineered for compatibility with both ARRMA Kraton and OutCast models. They function as direct replacements for the stock suspension arms, so installation is straightforward and requires no modifications to your chassis or existing components.
• What are the advantages of upgrading to aluminium suspension arms from plastic originals? — Aluminium suspension arms provide significantly improved durability, rigidity, and strength compared to plastic alternatives. They resist bending during aggressive driving, reduce unwanted flex in the suspension geometry, and ultimately last considerably longer before requiring replacement, making them a worthwhile investment for serious RC drivers.
• Are these suspension arms suitable for competitive racing? — Yes, these aluminium suspension arms are suitable for both casual bashing and competitive racing applications. The enhanced durability and improved suspension geometry control make them an excellent choice if you're looking to improve your vehicle's performance and reliability in racing environments.
• Do I need any tools or modifications to install these suspension arms? — These arms are designed as direct replacements for stock components and require no chassis modifications. You'll need basic RC tools (hex wrenches and screwdrivers) to remove the old arms and install the new ones, but no drilling or cutting is necessary.
• What is the difference between these Fastrax arms and the stock ARRMA components? — The primary differences are material composition and durability. Stock ARRMA suspension arms are typically made from injection-moulded plastic, while these Fastrax upgrades use precision-engineered aluminium alloy. This results in superior strength, better resistance to bending and damage, and longer component lifespan, especially under demanding driving conditions.
• Are these suspension arms covered by warranty? — As genuine Fastrax components purchased from an authorised retailer, these arms come with manufacturer warranty coverage. Contact RC Model Shop if you have questions about warranty terms and conditions.
