Overview

The RPM Front A-Arms Blue for Associated MT8 represent a significant upgrade over factory-standard suspension components, delivering the durability and reliability that serious RC enthusiasts demand. Whether you're running a competitive RC buggy or enjoying weekend bashing with your Associated MT8, these front A-arms are engineered to withstand the punishment that modern off-road RC racing and high-performance driving throws at your chassis. Built from RPM's renowned engineering-grade nylon blend, these suspension arms have been specifically designed to eliminate the weak points found in stock A-arm designs, giving you the confidence to push harder and bash faster without fear of suspension failure.

As an authorised retailer of premium RC components, RC Model Shop stocks this essential upgrade for drivers who refuse to compromise on durability. The MT8 is a capable platform, but its factory A-arms are vulnerable to the stresses of aggressive driving. RPM has identified every weakness in the original design and systematically reinforced each critical area, resulting in suspension arms that deliver measurably superior performance and longevity. If you're serious about keeping your Associated MT8 on the track or trail rather than on the workbench, this is the upgrade you need.

These blue front A-arms are sold as a pair and install directly in place of your stock Associated suspension components, making upgrading your RC car simple and straightforward. RPM's commitment to engineering excellence means you're not just buying replacement parts—you're investing in suspension components that will transform the durability and reliability of your RC driving experience.

Key Features

• 7% increased material at inner hinge pins — RPM engineers recognised that the inner hinge pin area is critical to A-arm longevity, so they increased the amount of material surrounding these pins by 7% to resist bending and stress concentration failures that commonly occur in this high-load zone.
• 40% wider inner hinge pin reinforcement — Not content with just adding material, RPM increased the width of the reinforced inner hinge pin area by nearly 40%, distributing stress more effectively across a larger surface area and dramatically improving durability under cornering loads.
• 28% improved material at outer hinge pins — The outer hinge pins also receive substantial reinforcement, with material thickness increased by 28% to withstand the lateral forces generated during aggressive turning and jump landings.
• 9% increased outer hinge pin width — Combined with the material improvements, RPM widened the outer hinge pin area by an additional 9%, creating a more robust mounting point that resists flex and cracking.
• Full-thickness support beams throughout — Stock A-arms are roughly 0.5 inches (12.7mm) thick at their centre but taper down significantly toward the hinge pins, losing nearly 30% of their thickness at critical stress points. RPM A-arms maintain a full 0.5-inch (12.7mm) thickness over nearly their entire length, only tapering slightly to 0.45 inches (11.43mm) at the innermost hinge pin bosses to match maximum allowable specifications.
• Four massive support beams instead of two — To compensate for the slight taper at inner hinge pins and to provide even greater reinforcement, RPM uses four substantial support beams rather than the two found on stock arms, making these the toughest A-arms available for the MT8.
• Engineering-grade nylon construction — All RPM A-arms are moulded from RPM's nearly indestructible blend of engineering-grade nylons, a material chosen for its exceptional strength-to-weight ratio, impact resistance, and reliability in demanding RC applications.
• Available in striking blue colour — These A-arms are moulded in vibrant blue, creating a sleek, modern aesthetic that looks professional both on the bench and on the track whilst being fully compatible with any MT8 colour scheme.
• Sold in pairs for complete front suspension upgrade — This package includes both left and right front A-arms, allowing you to upgrade your complete front suspension in one purchase and ensure perfectly matched components throughout.
• Direct replacement for stock Associated components — These arms are engineered to replace the factory A-arms from stock Associated part number 25911, ensuring perfect fitment without modification or additional parts required.

Technical Performance

RPM's engineering approach to front A-arm design represents a fundamental rethinking of how suspension arms should be constructed for modern RC racing and bashing. The comparison to stock A-arms is striking: where factory components sacrifice material thickness at the outer hinge pins to reduce weight or manufacturing cost, RPM maintains full thickness throughout, understanding that durability far outweighs marginal weight savings in real-world driving. The 7% increase in inner hinge pin material combined with the 40% width increase creates a substantially stronger stress-bearing surface that resists the bending loads generated during acceleration, deceleration, and cornering. Similarly, the 28% improvement in outer hinge pin material thickness paired with 9% additional width means these critical mounting points can withstand the lateral forces of aggressive turning and the shock loading from jumps and rough terrain.

The addition of four support beams instead of two fundamentally changes how forces distribute through the A-arm structure. This design philosophy, combined with the full-thickness engineering approach, means the RPM MT8 A-arms represent the most robust alternative to factory-supplied suspension components currently available. Built from nearly indestructible engineering-grade nylons, these arms deliver the kind of reliable performance that competitive RC enthusiasts and serious bashers depend on. Whether you're competing in organised RC racing events across the UK or enjoying high-speed weekend driving, these A-arms provide the structural integrity to handle sustained performance without failure.

Frequently Asked Questions

• Will these RPM front A-arms fit my Associated MT8? — Yes, these A-arms are specifically engineered as a direct replacement for the factory A-arms from stock Associated part number 25911 and will fit the MT8 without any modification or additional components required. Simply remove your stock arms and install these RPM components using the existing hinge pins and mounting points.
• How much more durable are RPM A-arms compared to stock? — RPM has made substantial improvements across every critical area: 7% more material at inner hinge pins with 40% greater width, 28% more material at outer hinge pins with 9% additional width, and a unique four-beam support structure instead of two. Most significantly, RPM A-arms maintain full 0.5-inch (12.7mm) thickness throughout their length rather than tapering down and losing 30% of their thickness like stock arms do, making them the toughest alternative to standard components available.
• Are these A-arms suitable for competitive RC racing? — Absolutely. These front A-arms are ideal for both competitive RC racing and recreational bashing. Their enhanced durability makes them particularly popular with racers who demand reliability during multiple heats and qualifying rounds, whilst bashers appreciate the confidence that comes from knowing their suspension can handle aggressive driving without breaking.
• What colour options are available? — RPM manufactures their MT8 A-arms in both black and blue, allowing you to choose whichever colour best matches your personal aesthetic or existing vehicle colour scheme. This product is the blue variant.
• Do I need any special tools to install these A-arms? — No, these arms use the same hinge pin system as factory components and install using standard RC model tools. If you can change your stock A-arms, you can install these RPM components without any difficulty.
• Are RPM A-arms a good first upgrade for my MT8? — Yes, front A-arm upgrades are an excellent first suspension modification. Many RC enthusiasts find that their stock A-arms are the first component to break under aggressive driving, making RPM A-arms one of the most practical and cost-effective upgrades available for the MT8 platform.
