Overview
The ARRMA Front Lower Suspension Arms 135mm (Pr) Z-ARA330656 are precision-engineered replacement suspension components designed for serious RC enthusiasts who demand reliability and performance. These heavy-duty front lower suspension arms have been built with ARRMA's characteristic toughness, making them an essential upgrade or replacement part for your brushless RC monster truck or speed truck. Whether you're a weekend basher pushing your RC car UK setup to its limits, or a competitive racer who needs components that can handle extreme conditions, these suspension arms deliver the durability and precision you expect from a leading RC manufacturer.
Built from tough composite materials with strategic reinforcement, these 135mm suspension arms are engineered to absorb impacts and resist crashes whilst maintaining the responsive handling characteristics that make modern brushless RC vehicles so exciting to drive. The pair includes both left and right arms, giving you everything needed to refresh or repair the front suspension geometry of compatible ARRMA models. This is a genuine OEM component that maintains factory specifications and performance standards.
RC car suspension is critical to vehicle performance, handling and longevity. Over time, even the toughest suspension arms can develop cracks or wear from impacts, high-speed runs, and jumps. These replacement arms ensure your RC truck maintains factory-spec suspension geometry, keeping your vehicle handling predictably and safely whether you're driving across rough terrain or on the track.
Key Features
- Heavy-Duty Design with Strategic Material Placement — The suspension arms feature composite construction with material positioned specifically to increase crash resilience, meaning they can absorb impacts from high-speed crashes and rough terrain without snapping or cracking, keeping your RC vehicle on the track for longer between repairs.
- Tough Composite Material Construction — Built from durable composite materials engineered for long-lasting performance, these arms resist the wear and tear that comes from regular bashing, racing and competitive driving, providing extended service life compared to standard plastic components.
- Precision Moulded Hinge Pin Holes — The hinge pin mounting points are precision moulded to exact specifications, ensuring smooth, slop-free suspension action that translates directly into more responsive steering inputs and better overall handling characteristics from your brushless RC truck or buggy.
- Sway Bar Mounting Holes — Integrated sway bar mounting holes provide a wide selection of handling options, allowing you to fine-tune your suspension geometry and anti-roll bar setup to match your driving style, track conditions, or racing requirements.
- Separate Alloy Suspension Arm End-Caps — Rather than relying on the composite material alone at the critical pivot ball mounting area, these arms use separate aluminium alloy end-caps that significantly increase strength and durability where the suspension connects to the chassis, a feature that extends component lifespan and reduces maintenance costs.
- Provided as a Pair — Package includes both the left and right front lower suspension arms, so you have everything needed for a complete front suspension refresh without purchasing multiple items separately.
Technical Performance
These front lower suspension arms measure 135mm in length and are specifically engineered for ARRMA's range of high-performance brushless RC vehicles including the 1/8 scale KRATON 6S EXB, NOTORIOUS 6S, OUTCAST 6S EXB and TALION 6S EXB speed trucks, as well as 1/7 scale models like the BIG ROCK 6S and FIRETEAM 6S buggy. The precision-moulded construction ensures consistent performance across both arms, eliminating any variation that might cause handling inconsistencies. The composite material used throughout provides an excellent balance between weight, strength and impact resistance, critical properties for vehicles running powerful brushless motors on 6S LiPo battery systems. The separate alloy end-caps are particularly important for high-performance applications, as they reinforce the suspension mounting points that experience the greatest stress during acceleration, braking and cornering. The sway bar mounting holes allow for suspension tuning that can improve both on-road and off-road handling depending on your setup preferences. Whether you're bashing casually or competing seriously, these arms maintain the factory specifications that make ARRMA vehicles so capable out of the box.

Frequently Asked Questions
- What ARRMA models are these suspension arms compatible with? — These 135mm front lower suspension arms are standard parts for the 1/8 scale KRATON 6S 4X4, KRATON 6S EXB 4X4, NOTORIOUS 6S 4X4, OUTCAST 6S 4X4, OUTCAST 6S EXB 4X4, TALION 6S 4X4 and TALION 6S EXB 4X4 models. They also fit the 1/7 scale BIG ROCK 6S 4X4 and FIRETEAM 6S 4X4 models. Check your vehicle documentation or contact us to confirm compatibility with your specific RC truck or buggy.
- Why do I need replacement suspension arms? — Over time and with regular use, especially on rough terrain or at high speeds, suspension arms can develop stress cracks or break entirely from impacts. Even if not visibly damaged, they can wear and develop play that affects handling. Replacement arms restore your vehicle to factory specifications and ensure predictable handling and suspension geometry.
- What is included and what do I need to buy separately? — The package includes left and right suspension arms. To complete installation, you will need shock mount pins (ARA713032) and suspension arm end caps (ARA330645) as specified in the requires section. These are often sold separately and may be required depending on your application.
- Are these original ARRMA parts or aftermarket replacements? — These are genuine OEM ARRMA parts manufactured to exact factory specifications, ensuring they fit perfectly and perform exactly as your vehicle was designed to perform from the factory. This guarantees compatibility and reliability with your brushless RC vehicle.
- Can these arms be used on other RC car brands? — No, these suspension arms are designed specifically for ARRMA vehicles. They are not compatible with other brands such as Traxxas or Losi. Always check the model number to ensure you have the correct parts for your specific RC car.
- How difficult is it to install these suspension arms? — Installation requires basic mechanical knowledge and tools including hex keys and possibly a small hammer or impact tool. If you are experienced with RC car maintenance, the job should take less than an hour. If you are not familiar with suspension work, we recommend having them installed by an experienced RC technician at your local hobby shop.
