Overview

The ARRMA Steering Knuckles (1 Pair) Z-ARA330558 are essential replacement parts for owners of high-performance 1/5 scale RC vehicles. Whether you are a seasoned RC enthusiast running an ARRMA Kraton or Outcast 8S brushless model, or someone who has experienced a crash during intense RC action, these steering knuckles are the perfect solution to get your vehicle back in top condition. Designed and manufactured by ARRMA, a recognised leader in the RC hobby space, these components deliver the durability and precision engineering you expect from genuine OEM spare parts for your RC car UK.

Steering knuckles are critical suspension components that connect your vehicle's steering system to the suspension arms, allowing smooth and responsive steering control. When subjected to the extreme forces of high-speed running, jumps, and impacts typical of 1/5 scale RC buggies and trucks, these parts can become damaged or worn. Having a quality replacement set on hand means minimal downtime and the ability to keep your RC truck performing at its best. The ARRMA Steering Knuckles (1 Pair) represent genuine ARRMA engineering, ensuring compatibility and reliability with your specific model.

These composite steering knuckles are engineered to withstand the demanding conditions faced by RC vehicles in the UK and beyond. Built from tough composite material with integrated metal reinforcement, they combine lightweight construction with exceptional crash resistance. Whether you bash in the garden, race on the track, or explore challenging terrain, these replacement knuckles will help maintain your vehicle's handling characteristics and steering precision.

Key Features

  • Tough Composite Material — Constructed from a durable composite material, these steering knuckles deliver increased crash resistance and long-lasting durability during the most extreme RC action, helping your vehicle survive hard impacts without breaking or cracking easily.
  • Molded-In Metal Reinforcement — Strategic metal reinforcement is moulded directly into the composite structure, adding significant amounts of strength to the pivot ball cups and preventing premature wear or failure during aggressive driving.
  • Precision Pivot Ball Housings — The carefully engineered pivot ball housings ensure smooth suspension and steering operation in all conditions, maintaining responsive steering response whether you are driving on smooth tarmac, dirt tracks, or rocky terrain.
  • Specially Designed Composite Steering Plate Spacers — Included spacers are precision-engineered to maintain correct suspension geometry and steering alignment, ensuring your RC vehicle handles predictably and performs as intended by the factory engineers.
  • Genuine OEM Replacement Parts — As official ARRMA spare parts, these knuckles are designed specifically for compatibility with your vehicle, guaranteeing fitment and performance without compromise or modification.

Technical Performance

The ARRMA Steering Knuckles Z-ARA330558 represent a significant engineering achievement in RC spare parts design. Built from composite material rather than brittle plastic, they provide a superior balance of weight savings and impact resistance. The moulded-in metal reinforcement directly addresses one of the most common failure points in RC vehicles — the pivot ball cups where the steering linkages connect. By integrating metal inserts into the composite matrix, ARRMA has created a component that resists the crushing forces generated during high-speed direction changes and hard landings from jumps. The precision-engineered pivot ball housings maintain tight tolerances, which is essential for smooth, responsive steering operation across all driving conditions. This level of precision engineering is particularly important for 1/5 scale vehicles like the ARRMA Kraton and Outcast 8S, which are capable of extreme speeds and aggressive manoeuvres that place enormous stresses on suspension components. The included steering plate spacers are not mere afterthoughts; they are precision-engineered components that maintain the correct suspension geometry and ensure your vehicle's handling characteristics remain true to the factory specification.

Frequently Asked Questions

  • What vehicles are these ARRMA Steering Knuckles compatible with? — These Z-ARA330558 steering knuckles are specifically designed for the ARRMA 1/5 Outcast 4X4 8S BLX EXB Brushless Stunt Truck RTR. Always verify your model number before purchasing to ensure correct fitment with your RC vehicle.
  • Why would I need replacement steering knuckles for my RC truck? — Steering knuckles can become damaged from crashes, hard landings, or sustained use during competitive racing and bashing. They may develop cracks, stripped ball cups, or wear that compromises steering response. Having a replacement pair ensures you can quickly repair your vehicle and get back to driving without extended downtime.
  • Are these better than the plastic steering knuckles on stock RC vehicles? — Yes, these ARRMA genuine OEM knuckles feature moulded-in metal reinforcement that adds significant strength to the pivot ball cups compared to standard plastic components. This means they resist impact damage more effectively and maintain their precision geometry longer, particularly important for high-performance 1/5 scale brushless RC trucks.
  • What makes these knuckles different from aftermarket alternatives? — These are genuine ARRMA factory parts engineered specifically for your vehicle model. They are designed with the same specifications and tolerances as the original components, guaranteeing perfect fitment, compatibility, and performance. Aftermarket alternatives may vary in material quality, precision, and durability.
  • How difficult is it to fit these steering knuckles? — Replacement typically requires basic RC tools and mechanical knowledge. You will need to remove the steering linkages and suspension arms connected to the old knuckles, then bolt the new ones in place. If you are unfamiliar with RC vehicle maintenance, we recommend consulting your vehicle manual or seeking assistance from experienced RC enthusiasts in the UK RC community.
  • Will these knuckles improve my vehicle's handling? — If your original knuckles are damaged or worn, replacing them with these genuine ARRMA parts will restore your vehicle's handling to factory specification. New knuckles with tight tolerances in the pivot ball housings will provide smoother, more responsive steering compared to worn components, helping your RC car perform at its best.
