Overview

The ARRMA Suspension Arm Rear (2): 4x4 Z-AR330516 represents an essential replacement part for serious RC enthusiasts in the UK who demand reliability and performance from their 4x4 RC vehicles. Whether you're running an ARRMA Granite, Senton, Big Rock, or Vorteks model, these rear suspension arms are engineered to withstand the punishment of aggressive off-road driving whilst maintaining precise handling characteristics. These replacement components are designed as direct replacements for worn or damaged suspension arms, making them an indispensable part of any RC hobbyist's spare parts collection.

If you've invested in a quality ready-to-run RC truck or monster truck, protecting that investment with genuine ARRMA replacement parts is crucial. The suspension arms are among the most frequently replaced components in RC vehicles, taking the full force of impacts, jumps, and aggressive terrain. Having a spare set of rear suspension arms on hand means less downtime and more hours enjoying your RC car UK experience. These arms are perfect for bashers, weekend racers, and those who push their vehicles to the limit.

ARRMA has built a reputation for creating robust, competition-grade RC vehicles and equally dependable spare parts. These rear suspension arms exemplify that commitment to quality, featuring composite construction that balances durability with weight considerations. Whether you're repairing after a crash or simply maintaining your vehicle, the Z-AR330516 delivers the authentic performance and reliability that ARRMA owners expect.

Key Features

• Tough Composite Material — These rear suspension arms are manufactured from tough composite material that provides increased crash resistance and long-lasting durability, meaning they'll withstand the rigours of off-road RC driving without cracking or breaking under normal use, saving you money on repairs.
• Precision Manufactured Shock Mounting Holes — The shock mounting holes are precision-engineered to ensure perfect alignment with your RC vehicle's shock absorbers, delivering added fit security and eliminating the sloppiness that can develop in inferior replacement parts, which directly translates to better handling and more predictable performance.
• Specially Designed Hinge Pin Capture Screw Holes — The hinge pin capture screw holes are specially designed for maximum reliability, preventing the hinge pins from shifting or becoming loose during aggressive cornering or high-impact landings, which keeps your suspension geometry consistent throughout your driving session.
• Includes Two Rear Suspension Arms — This package includes 2 rear suspension arms, giving you a complete replacement set for the rear axle of your 4x4 RC vehicle, eliminating the need to purchase multiple single arms separately.
• Wide Vehicle Compatibility — These arms are compatible with numerous ARRMA 4x4 models including the Big Rock 3S, Granite, Senton, and Vorteks ranges, making them an excellent spare to have on hand regardless of which ARRMA platform you're running.

Technical Performance

These rear suspension arms represent ARRMA's commitment to engineering excellence in the brushless RC truck and monster truck segment. The composite construction provides an optimal balance between weight savings and structural rigidity, ensuring that your vehicle maintains its intended suspension geometry even under extreme driving conditions. The precision-manufactured shock mounting holes are critical to maintaining the exact geometry that ARRMA engineers designed into each model, whether you're running a brushless 3S LiPo-powered monster truck or a brushed alternative. The specially designed hinge pin capture screw holes prevent movement of the suspension geometry during cornering and impact, which is particularly important in high-performance 4x4 RC buggies and short-course trucks that demand split-second handling response. These arms have been tested and validated across the full range of ARRMA 4x4 platforms, from the BIG ROCK through to the VORTEKS, confirming their suitability for the varying torque outputs and driving styles encountered in the ready-to-run RC car UK market. The composite material selection ensures that these arms won't shatter under the typical impacts encountered in RC bashing, whilst remaining light enough to maintain the suspension tuning characteristics for which your specific ARRMA model was engineered.

Frequently Asked Questions

• Which ARRMA models are these rear suspension arms compatible with? — These Z-AR330516 arms are compatible with a comprehensive range of ARRMA 4x4 models including the Big Rock 3S (all versions), Granite (brushed and brushless 3S variants), Senton (brushed and brushless 3S variants), and Vorteks 3S models. Check the manufacturer specifications for your specific model variant to confirm fitment.
• How often should I replace my RC suspension arms? — Suspension arms should be replaced when they become cracked, bent, or when excessive slop develops in the hinge pin attachment points. For regular bashers, you might expect to replace them every 6-12 months of active use, depending on your driving style and terrain. Having spare arms like this Z-AR330516 set on hand means you can swap them out quickly and get back to driving rather than waiting for replacements to arrive.
• Are these suitable for competition racing or just casual bashing? — These suspension arms are suitable for both casual bashing and competitive driving. ARRMA vehicles are raced competitively worldwide, and these genuine replacement parts are engineered to the same specifications as the original equipment on your RTR vehicle. Whether you're a weekend basher or competing in local RC club events, these arms will give you the reliability and performance you need.
• What is the difference between these composite arms and aluminium alternatives? — Composite arms like these offer excellent crash resistance and are less likely to crack under impact, whereas aluminium arms might bend permanently. The composite construction in these ARRMA arms makes them forgiving for aggressive driving and bashing, which is why they're specified as original equipment on many ARRMA 4x4 models. Some aftermarket aluminium upgrades are available, but these genuine ARRMA composites are perfect for replacement and repair.
• Can I install these arms myself or do I need a hobby shop? — These are straightforward replacement parts that any RC enthusiast can install with basic tools. You'll need a small screwdriver or hex key to remove the hinge pins and mounting screws, and installation typically takes less than 15 minutes per arm. The precision-manufactured mounting holes ensure a perfect fit without any modifications needed.
• Do these come with hinge pins and screws? — The Z-AR330516 includes the suspension arms themselves. Depending on your vehicle condition, you may be able to reuse your existing hinge pins and mounting screws, or you might want to order replacement hardware at the same time for a completely fresh setup.
