RPM Traxxas X-Maxx Upper and Lower Suspension Arms Orange RPM82358

Overview

The RPM Traxxas X-Maxx Upper and Lower Suspension Arms represent a significant upgrade over the standard Traxxas components, engineered specifically for the massive X-Maxx monster truck platform. If you own or are planning to purchase a Traxxas X-Maxx RC monster truck in the UK, these premium replacement suspension arms are essential upgrades that will transform your driving experience and dramatically improve durability during aggressive off-road bashing sessions. The X-Maxx is an exceptionally large and powerful brushless 4WD monster truck that demands equally robust suspension components, and RPM has delivered exactly that with these battle-tested A-arms.

These suspension arms are engineered from the ground up to address the specific weaknesses identified in the original Traxxas stock components. RPM's engineering team conducted extensive analysis of real-world failures and studied damaged stock arms to pinpoint exactly where breakage occurs under extreme conditions. The result is a suspension upgrade that is both significantly stronger and noticeably lighter than the factory equipment, giving you the confidence to bash harder and jump higher without fear of costly repairs. For any serious X-Maxx owner looking to push their RC vehicle to its absolute limits, upgrading to RPM suspension arms is one of the smartest investments you can make.

Whether you're a weekend basher, a competitive RC enthusiast, or someone who simply wants the most robust setup for your ready-to-run brushless RC monster truck, these arms deliver the performance and reliability you need. Available in multiple colour options including orange, black, green, and blue, you can match your chosen scheme perfectly whilst benefiting from engineering-grade durability that far exceeds standard plastic components found on stock RC vehicles.

Key Features

• Stronger and Lighter Construction — RPM has engineered these suspension arms using a carefully formulated blend of ultra-tough, engineering-grade nylons that deliver superior strength compared to the original Traxxas #7729, #7730, and #7731 components, whilst maintaining a lighter overall weight that improves handling and reduces stress on other drivetrain components.
• Proven Upper A-Arm Design — The upper arms are built using RPM's battle-tested designs from previous high-impact RC platforms, creating an upper support structure with serious strength concentrated exactly where it matters most during aggressive jumps and hard landings.
• Improved Lower A-Arm Geometry — The lower arms feature enhanced ground clearance over stock components and incorporate a cross-section inspired by RPM's proven 1/5-scale HPI Baja A-arms, delivering big-scale toughness and durability to your X-Maxx suspension.
• Double Support Beam Technology — A revolutionary double support beam integrated into the lower arms spreads impact energy across a much wider area, dramatically reducing concentrated stress that would otherwise cause breakage during brutal landings and crash scenarios.
• Universal Fit Design — These arms are engineered to fit any corner of your X-Maxx truck, eliminating confusion and ensuring compatibility regardless of where you install them on your vehicle.
• USA Manufacturing and Premium Materials — Moulded from RPM's trademark blend of engineering-grade nylons and proudly manufactured in the United States, these components maintain the highest quality standards throughout production.
• Industry-Leading Warranty Protection — Every set is backed by RPM's industry-leading limited lifetime warranty against breakage, giving you complete peace of mind and worry-free performance you can absolutely rely on.
• Complete Package per Vehicle — Each package contains one upper and one lower A-arm; four packages are required to completely outfit your X-Maxx with upgraded suspension arms on all four corners.
• Multiple Colour Options — Available in black, green, orange, and blue, allowing you to select the colour that best complements your X-Maxx's body colour and personal style preferences.

Technical Performance

The RPM Traxxas X-Maxx Upper and Lower Suspension Arms represent a quantum leap in suspension durability for this incredible 4WD brushless monster truck platform. These components are engineered from engineering-grade nylon compounds that have been rigorously tested to withstand the enormous stresses generated by the X-Maxx's powerful brushless 8S LiPo drivetrain. The X-Maxx is an exceptionally large and heavy monster truck that can deliver tremendous punishment through its suspension during high-speed jumps, hard impacts, and aggressive off-road driving sessions typical of UK RC enthusiasts who push their brushless RC vehicles to their limits. RPM's upper arms utilise design principles proven across multiple high-impact platforms, ensuring maximum strength without unnecessary weight addition. The lower arms benefit from enhanced ground clearance compared to factory components, preventing unwanted drag and binding during extreme suspension articulation. The innovative double support beam design is particularly significant; by spreading impact forces across a larger structural area rather than concentrating them at single failure points, these arms can absorb the punishment that would destroy standard components. The engineering-grade nylon material used throughout provides superior impact resistance and flex characteristics compared to inferior plastics, whilst the USA manufacturing ensures consistent quality and precision moulding throughout production. These suspension upgrades are compatible with all X-Maxx variants and integrate seamlessly with the truck's existing suspension geometry and shock absorber systems. Heavy users, those performing big jumps, or those running extreme power setups should consider pairing these arms with RPM's threaded hinge pins (RPM #70510, sold separately) for maximum reliability under the most demanding conditions.

Frequently Asked Questions

• How many RPM A-arm packages do I need for my X-Maxx? — Each package contains one upper and one lower A-arm. Since the X-Maxx has four corners, you will need four complete packages to fully outfit your vehicle with upgraded suspension arms on all corners.
• Are these arms compatible with all Traxxas X-Maxx models? — Yes, these RPM suspension arms are compatible with all Traxxas X-Maxx variants including the standard X-Maxx, X-Maxx Ultimate, and all colour variations. They replace the factory upper arm from stock Traxxas #7729 and replace the lower arms from stock Traxxas #7730 and #7731.
• Can I fit these RPM arms on any corner of the truck? — Absolutely. RPM has engineered these arms with universal fit design, meaning they will fit on any corner of your X-Maxx without modification or confusion about left versus right installation.
• What is the advantage of the double support beam in the lower arms? — The double support beam spreads impact energy across a much wider structural area during crashes and hard landings, reducing concentrated stress at single points that would otherwise cause breakage in factory components. This technology is derived from RPM's proven 1/5-scale HPI Baja arms.
• Are these arms suitable for heavy bashing and jumping? — These RPM arms are specifically designed for heavy bashing and jumping applications. For extremely heavy use, big jumps, or extreme power setups, RPM recommends upgrading to their threaded hinge pins (RPM #70510) for maximum reliability.
• Do these arms fit without any additional modifications? — For most users, no additional parts are necessary. These arms integrate seamlessly with your existing X-Maxx suspension and chassis. Heavy users and those running extreme setups may benefit from optional RPM threaded hinge pins.
• What colour options are available for these suspension arms? — RPM offers these X-Maxx A-arms in four colours: orange, black, green, and blue, allowing you to select the option that matches your truck's body colour and personal preferences.
• Are these arms manufactured in the USA? — Yes, RPM proudly manufactures these X-Maxx A-arms in the United States using their trademark blend of engineering-grade nylons, ensuring premium quality and consistency throughout production.
• What warranty does RPM provide with these arms? — These arms are backed by RPM's industry-leading limited lifetime warranty against breakage, providing comprehensive protection and peace of mind during your RC bashing sessions.
