Overview
The ARRMA HD Chassis Brace Set (ARA320555) is an essential replacement and upgrade component for serious RC enthusiasts running high-performance brushless RC trucks and buggies. Whether you're a dedicated basher pushing your RC vehicle to its limits or a competitive racer looking to reinforce your chassis against the stresses of extreme driving, this heavy-duty brace set delivers the structural reinforcement your model needs. ARRMA has engineered this set specifically to address the high-stress points on your RC car's chassis, providing the durability and reliability that serious RC hobbyists demand when they're running 6S brushless power through demanding conditions.
This is not a cosmetic upgrade—it's a performance-critical component designed for those who understand that chassis integrity directly impacts handling, durability and overall RC car longevity. If you're running a 1/8 scale ARRMA brushless speed truck, stunt truck, or buggy at full throttle across rough terrain, the HD Chassis Brace Set transforms your vehicle's structural rigidity. The precision engineering ensures that every component fits perfectly with your existing ARRMA platform, maintaining the exact geometry your vehicle was designed for whilst adding significant strength where it matters most.
Available now at RC Model Shop, this is the genuine ARRMA component trusted by RC enthusiasts across the UK who refuse to compromise on quality or performance. Whether you're upgrading a new RTR (ready to run) model or refreshing a well-used basher, the HD Chassis Brace Set is the investment that keeps your RC truck or buggy performing at its absolute best.
Key Features
- Strategically Engineered Reinforcement — The braces are positioned to add strength in highly-stressed areas of the chassis, targeting the specific points where extreme RC driving generates the most mechanical stress and potential flex, ensuring your vehicle maintains structural integrity under demanding conditions.
- Tough Composite Material Construction — Manufactured from durable composite material specifically selected for RC applications, these braces offer long-lasting durability during extreme RC action, resisting the punishment of high-speed bashing, competitive racing, and rough terrain without cracking or warping.
- Precision Manufactured Mounting Holes — Every mounting hole is manufactured to exacting tolerances, guaranteeing a secure and reliable fit with your ARRMA chassis, with no wobble, movement, or alignment issues that could compromise handling or cause component failure.
- Integrated Wire Tidy Loop — A specially designed wire tidy loop is incorporated into the brace design, allowing you to neatly route and manage electrical wiring and servo leads, keeping your RC vehicle's internal layout clean, organised and protected from snagging during aggressive driving.
- Complete Multi-Piece Set — The set includes everything needed for a comprehensive chassis reinforcement upgrade with front and rear brace options, plus spacers for correct alignment and installation flexibility.
Technical Performance
The HD Chassis Brace Set represents ARRMA's commitment to engineering excellence in composite chassis reinforcement. Built from composite material proven to withstand the demands of brushless RC power delivery—whether you're running a 1/8 KRATON 6S Speed Truck at full acceleration, piloting a NOTORIOUS 6S Stunt Truck through technical courses, or racing a TYPHON 6S Buggy at competition speeds—these braces add measurable structural stiffness to your chassis platform. The composite material choice is critical: it provides the necessary rigidity to resist flex and twisting during aggressive cornering and acceleration, whilst remaining light enough that it doesn't adversely affect your vehicle's power-to-weight ratio or handling characteristics. The precision manufacturing of mounting holes ensures perfect alignment with your ARRMA chassis, maintaining the exact suspension geometry and weight distribution that ARRMA engineers designed into your vehicle. This is professional-grade reinforcement that performs equally well whether you're bashing at the local park or competing at organised RC events across the UK.
