The investment in quality suspension upgrades like these A-arms demonstrates a commitment to maximising your RC vehicle's potential and longevity.

Key Features

• 30-Degree Leading and Trailing Edges — RPM engineered unique 30-degree leading and trailing edges into these front A-arms to fundamentally change how your RC buggy interacts with obstacles and rough terrain. Rather than ploughing into or forcing through tall objects, these edges help the vehicle transition smoothly up and over them, improving ground clearance and reducing impact damage during aggressive off-road driving.
• Oversized Hinge Pin Bosses — The hinge pin mounting bosses are significantly enlarged to provide superior support in this high-stress area of the suspension. Oversized bosses mean greater surface area for load distribution, reducing stress concentration and dramatically improving component longevity during intense driving sessions.
• Oversized Shock Mount Bosses — RPM has enlarged the shock mounting points by at least 10% in diameter and as much as 65% in width compared to stock A-arms. This substantial increase in boss size at this critical junction where shocks connect to the A-arms ensures the suspension system can handle the forces generated during acceleration, braking and cornering without fatigue or failure.
• Oversized Screw Bosses — The bosses designed to accommodate fastening screws have been enlarged across the component. This extra material surrounding screw mounting points prevents the common failure mode of threads stripping out, ensuring your A-arms remain securely fastened throughout extended driving sessions.
• Optimised Rear Shock Mount Angle — Engineers at RPM tweaked the shock mount angle specifically for the EXO Terra Buggy to eliminate suspension bind that occurs at the lower shock pivot ball when the suspension reaches full droop. This refinement means smoother suspension action throughout the entire travel range and better overall handling characteristics.
• Reduced Unsprung Weight — A complete set of RPM front and rear A-arms weighs less than stock factory arms, shedding unsprung weight from your RC buggy. This reduction in unsprung mass improves suspension response, helps the tyres maintain better ground contact, and enhances overall vehicle agility and cornering behaviour.
• Precision Hinge Pin Holes — RPM has refined the hinge pin hole diameters to exactly 0.118 inches or 3mm, cutting nearly 0.004 inches (0.1mm) of slop from each hinge pin. This precision engineering eliminates play in the suspension and steering systems, resulting in tighter, more responsive handling that directly improves driving confidence and control.
• Advanced Material Blend — These A-arms are moulded from RPM's trademark blend of incredibly strong materials, the same formula that has earned the brand recognition for producing some of the toughest RC suspension components available. The material composition provides the optimal balance between impact resistance and weight efficiency.
• Limited Lifetime Warranty — All RPM moulded products, including these A-arms, are backed by the manufacturer's limited lifetime warranty against breakage. This demonstrates RPM's confidence in their engineering and provides peace of mind that your investment is protected against manufacturing defects.
• Black Colour Finish — The distinctive black colour finish provides excellent visual appeal whilst remaining practical for maintenance and inspection of the suspension components.

Technical Performance

These front A-arms are engineered with materials science and suspension geometry at the forefront of the design philosophy. The oversized mounting bosses—larger by at least 10% in diameter and up to 65% in width—address the high-stress zones where failures typically occur in stock suspension arms. The 0.118-inch hinge pin holes represent precision manufacturing that eliminates suspension slop, directly improving the responsiveness of your EXO Terra Buggy's steering and suspension systems. The 30-degree leading and trailing edges aren't merely aesthetic; they fundamentally alter how the suspension geometry works as the A-arm articulates, allowing your RC buggy to climb over obstacles rather than catch on them. The optimised shock mount angle prevents binding at full suspension droop, ensuring smooth action across the entire suspension travel envelope. When paired with the weight savings compared to factory components, the overall effect is a suspension system that responds more quickly, handles more predictably, and lasts considerably longer under the stresses of serious RC driving. The material blend used throughout these arms provides exceptional impact resistance whilst maintaining the lightweight characteristics that serious RC buggy enthusiasts demand.

Frequently Asked Questions

• Are the RPM Front A-arms compatible with my Axial EXO Terra Buggy? — Yes, these A-arms are specifically engineered for the Axial EXO Terra Buggy platform. They are designed to integrate seamlessly with the EXO Terra's suspension geometry and mounting points, making installation straightforward for anyone with basic RC maintenance knowledge.
• How much stronger are these A-arms compared to stock components? — RPM has enlarged the critical mounting bosses by at least 10% in diameter and as much as 65% in width compared to stock A-arms. These substantial increases in material around high-stress areas significantly improve durability without excessive weight penalty. The precision hinge pin holes cut nearly 0.004 inches of slop from the suspension, improving both durability and handling responsiveness.
• Will these A-arms improve my EXO Terra Buggy's handling? — Yes, in multiple ways. The reduced hinge pin hole slop means tighter steering response and less play in the suspension system. The optimised shock mount angle eliminates binding at full suspension droop, allowing smoother suspension action. The 30-degree leading and trailing edges improve how your buggy transitions over obstacles, and the weight savings enhance overall agility and cornering behaviour.
• What is the warranty on RPM A-arms? — RPM backs all moulded products, including these front A-arms, with a limited lifetime warranty against breakage. This warranty demonstrates the manufacturer's confidence in the engineering and materials used in their components.
• Are these suitable for beginner RC enthusiasts? — Whilst these are high-quality upgrade components, they are ideal for anyone owning an Axial EXO Terra Buggy who wants to improve durability and handling. Beginners benefit from the increased durability, whilst experienced drivers appreciate the refined geometry and reduced slop. Installation requires basic RC maintenance skills or can be performed by an experienced hobby shop.
• What makes RPM A-arms different from other suspension upgrades? — RPM's 30-degree leading and trailing edges are a unique design feature found only on RPM A-arms, helping vehicles transition over obstacles rather than ploughing through them. The oversized bosses at all critical stress points (hinge pins, shock mounts, screws) are substantially larger than on competing products. The precision 0.118-inch hinge pin holes cut slop more aggressively than most alternatives. Additionally, the optimised shock mount angle specifically eliminates bind issues found in stock EXO Terra suspension, showing RPM's deep understanding of this platform's requirements.
• Do I need any special tools to install these A-arms? — These A-arms use standard hinge pin and mounting points compatible with the EXO Terra Buggy platform. Basic RC tools such as hex drivers and screwdrivers are typically required, along with appropriate fasteners. Detailed installation guidance is recommended before beginning work.
