Technical Performance
The ARRMA Rear Suspension Arms represent the engineering standard for modern brushless RC truck performance. Manufactured from composite materials selected for their balance of strength and weight, these arms deliver responsive suspension geometry that translates driver input into precise vehicle movement. The hinge pin mounting system works in conjunction with ARRMA's carefully engineered suspension angles to provide optimal camber and toe-in characteristics, directly impacting how your Kraton or Outcast corners, accelerates and maintains stability during high-speed runs. The shock mounting holes are designed to accommodate standard ARRMA shock absorbers, ensuring proper damping characteristics and ride height. The precision manufacturing tolerances mean minimal play in the suspension linkage, which is critical for competitive performance in RC racing UK championships. Composite material offers an excellent strength-to-weight ratio compared to plastic alternatives, meaning your suspension responds faster to terrain changes while resisting the repeated impacts common in aggressive driving. Whether you're bashing jumps, running rock crawls or pushing lap times on a track, these suspension arms form the foundation of reliable, predictable handling that keeps your RC car performing at its best.

Frequently Asked Questions
- Will these suspension arms fit my ARRMA RC car? — Yes, these arms are specifically engineered for the ARRMA Kraton 4S V1 (ARA102690) and ARRMA Outcast 4S V1 (ARA102692). If you own either of these models, these suspension arms will fit perfectly. They replace the earlier AR330521 specification. Always verify your exact model before ordering to ensure compatibility.
- Why would I need replacement suspension arms? — Suspension arms experience wear and impact damage during normal RC car operation. Hard crashes, jumps and aggressive bashing can crack or break suspension components. Having spare arms on hand means you can quickly swap damaged parts and get back to driving without downtime. Many serious RC enthusiasts UK keep spares in their pit box for track days and races.
- Are these composite arms durable enough for serious driving? — Absolutely. ARRMA's composite suspension arms are designed for serious performance in both casual bashing and competitive racing. The material offers excellent impact resistance and maintains its structural integrity through countless driving sessions. However, like all suspension components, they will eventually wear or break with heavy use—having spares ensures continuous enjoyment of your RC truck.
- Do I need any tools to install these suspension arms? — Basic RC tools will be needed to remove and install the suspension arms, including hex drivers and possibly a shock tool to access mounting points. The installation is straightforward for anyone with RC experience, as it involves removing hinge pins and shock mounts from the damaged arms and transferring them to the new arms, or installing new mounting components if required.
- What is the difference between these arms and generic aftermarket versions? — These are genuine ARRMA parts engineered to exact OEM specifications. Generic aftermarket arms may have looser tolerances in the mounting holes, leading to poor suspension geometry, sloppy handling and premature wear. ARRMA genuine parts guarantee precision fit, proper suspension alignment and performance that matches your vehicle's original engineering standards.
