Overview
The Fastrax ARRMA Rear Aluminium Brace for Upper Arms is a premium upgrade component designed specifically for ARRMA's high-performance 4WD monster trucks and bashers. This precision-engineered aluminium brace is compatible with the ARRMA Kraton, OutCast, Senton, and Typhon model ranges, making it an essential upgrade for serious RC enthusiasts across the UK who demand reliability and durability from their RC vehicles. Whether you're a weekend basher pushing your RC truck to its limits or a competitive racer looking for chassis reinforcement, this rear upper arm brace delivers the structural support needed to handle aggressive driving conditions.
Manufactured by Fastrax, a recognised name in RC performance parts, this aluminium brace represents a smart investment in your ARRMA RC car's longevity and performance. The rear upper arm mounting points are subject to significant stress during off-road driving, particularly when landing jumps, navigating rough terrain, or executing high-speed manoeuvres. By upgrading to this reinforced aluminium brace, you're directly addressing one of the weakest points in your suspension geometry, ensuring your RC monster truck maintains consistent handling characteristics and resists chassis flex that can compromise handling precision.
This is the kind of upgrade that separates casual RC operators from dedicated enthusiasts who understand how chassis reinforcement translates to better performance, improved durability, and ultimately a more enjoyable RC driving experience. At RC Model Shop, we stock this component because we know ARRMA owners appreciate quality upgrades that make a measurable difference to their machines.

Technical Performance
This aluminium brace represents precision engineering at its finest for ARRMA RC vehicle upgrades available across the UK market. The use of aluminium as the primary material provides an optimal balance between weight savings and structural strength—critical factors for maintaining your RC truck's performance envelope. The rear upper arm brace directly addresses chassis deflection, which occurs when the aluminium chassis flex excessively under load. By providing additional triangulation and support at the upper arm mounting interface, this component significantly improves suspension response predictability and handling precision. The engineering behind this component considers the specific stress patterns experienced by ARRMA's suspension architecture during aggressive driving, off-road bashers sessions, and competitive racing scenarios. Installation integrates seamlessly with your existing ARRMA Kraton, OutCast, Senton, or Typhon platform without requiring any chassis modifications or drilling, making this an elegant solution for reinforcement that respects the original engineering while enhancing durability. The aluminium construction ensures this brace will endure repeated impacts, vibration, and the extreme forces generated during high-speed driving, landing jumps, and technical rock crawling sections that many UK RC enthusiasts encounter in their local driving areas.
