If you're running an Arrma Grom or Granite and seeking to improve suspension performance without breaking the bank, this Fastrax aluminium rear lower arms kit represents outstanding value for money. The investment in quality suspension components directly translates to better vehicle control, improved cornering precision, and enhanced durability during extended bash sessions or competitive racing. Available now at RC Model Shop, these parts are in stock and ready to ship to RC enthusiasts across the UK.

Key Features

• Premium Aluminium Construction — Unlike standard plastic lower arms, these components are manufactured from high-grade aluminium alloy, providing exceptional strength-to-weight ratio and superior rigidity that directly improves suspension response and vehicle handling during aggressive driving manoeuvres.
• Pair Included — You receive a complete pair of rear lower arms, meaning both sides of the rear suspension are upgraded simultaneously, ensuring balanced geometry and consistent performance characteristics across the vehicle's entire rear axle assembly.
• Direct Fit Design — These arms are precision-engineered to fit Arrma Grom and Granite models without modification, allowing for straightforward installation by users with basic RC mechanical knowledge and standard hand tools.
• Reduced Flex and Deflection — The rigid aluminium construction minimises unwanted suspension flex under load, maintaining precise suspension geometry during cornering, acceleration and braking, which translates to more predictable vehicle behaviour and improved driver confidence.
• Enhanced Durability — Aluminium components resist the cracking and breaking that commonly occurs with plastic arms when subjected to impacts and aggressive driving conditions, significantly extending the service life of your suspension system.
• Performance Upgrade Path — These arms represent an ideal first suspension upgrade for Arrma owners seeking to improve handling without investing in complete suspension overhauls, making them perfect for progressive tuning approaches.

Technical Performance

The Fastrax Arrma Grom/Granite Aluminium Rear Lower Arms deliver measurable performance improvements through their engineering approach and material selection. Constructed from premium aluminium alloy rather than injection-moulded plastic, these components provide dramatically increased rigidity whilst maintaining a lightweight profile essential for responsive 1/10 scale RC vehicles. The aluminium material resists the deflection and flex inherent in plastic suspension arms, meaning the suspension geometry remains consistent even under the high lateral forces experienced during fast cornering manoeuvres or aggressive bash sessions. This geometric consistency translates directly to improved steering response, better traction characteristics, and more predictable handling behaviour—essential qualities whether you're enjoying casual RC bashing at home or competing at a UK RC track. The precision manufacturing ensures tight tolerances at bearing locations, eliminating play that would compromise suspension performance. Installation is straightforward, requiring only basic tools and mechanical knowledge, with bolt-on compatibility to existing Arrma Grom and Granite suspension systems. For RC enthusiasts seeking to elevate their vehicle's performance without major expense or complexity, these rear lower arms represent a targeted, cost-effective upgrade that delivers genuine handling improvements.

Frequently Asked Questions

• Will these Fastrax aluminium rear lower arms fit my Arrma Grom or Granite? — Yes, these arms are precision-engineered specifically for Arrma Grom and Granite models and require no modification for installation. They bolt directly onto your existing rear suspension assembly using standard hardware.
• What is the main advantage of upgrading to aluminium lower arms over the stock plastic components? — Aluminium provides significantly greater rigidity, eliminating the flex and deflection common in plastic suspension arms. This results in more consistent suspension geometry, improved handling predictability, and substantially longer component lifespan, especially during aggressive driving or competitive racing.
• Are these suitable for beginners or casual RC enthusiasts? — Absolutely. Whilst these components are high-quality performance upgrades, they are straightforward to install and deliver immediately noticeable improvements in vehicle handling. No special knowledge or tools are required beyond basic hex wrenches and screwdrivers, making them ideal for anyone looking to enhance their RC car UK setup progressively.
• Do I need to replace any other suspension components when installing these rear lower arms? — No, these arms are designed as a direct replacement for standard plastic rear lower arms. Existing bearings and hardware can typically be transferred to the new aluminium components, though inspecting bearings during installation and replacing them if worn is recommended best practice.
• Will installing these arms significantly improve my Arrma's performance? — Yes, you should notice improved cornering precision, better handling consistency, and enhanced overall vehicle responsiveness. The reduction in suspension flex means the vehicle maintains its intended geometry throughout aggressive manoeuvres, translating to more predictable and controllable handling characteristics.
• What tools do I need to install these components? — You'll need basic hex wrenches (likely sizes already in your RC toolkit) and potentially a small screwdriver depending on your specific Arrma model's hardware. No specialised tools or equipment are required for straightforward installation.
