RPM Traxxas X-Maxx Upper and Lower A-Arms Black Suspension RPM82352

Overview

The RPM Traxxas X-Maxx Upper & Lower A-Arms in Black (RPM82352) represent a significant upgrade from stock suspension components for one of the most demanding RC monster trucks on the market. Immediately after Traxxas released the X-Maxx, RC enthusiasts across the UK and beyond demanded stronger A-arms capable of handling the massive weight and relentless punishment these giant 1/5 scale machines deliver. RPM listened to customer feedback, analysed countless photos of damaged stock A-arms to identify weak points, and engineered a completely redesigned suspension solution that is both stronger and lighter than the original equipment.

Whether you're a serious RC basher looking to tackle rough terrain, a competitive racer pushing your X-Maxx to its limits, or an experienced RC hobbyist in the UK seeking maximum durability and performance, these A-arms are engineered specifically for your needs. RPM's engineering team drew upon their extensive experience with proven suspension designs from successful past builds to create an upper support structure that can handle absolutely anything you throw at it. The result is a suspension upgrade that transforms the handling, reliability and longevity of your Traxxas X-Maxx.

Available in striking Black as well as Green and Blue colour options, the RPM 82352 A-arms come as a single upper and single lower arm package. Since your X-Maxx requires four arms total (one per corner), you'll need to purchase four of these packages to complete a full vehicle setup. These suspension components are manufactured in the United States from RPM's trademark blend of incredibly tough engineering-grade nylon, ensuring years of reliable performance backed by RPM's industry-leading limited lifetime warranty against breakage.

Key Features

• Stronger than Stock — RPM engineered these A-arms specifically to handle the weight and punishment of the X-Maxx, utilising reinforced structures and proven design principles to deliver dramatically improved durability compared to the standard Traxxas components you may have been running previously.
• Lighter than Stock — Despite being significantly stronger, these arms are also lighter than the original equipment, which improves your truck's acceleration, handling response and overall performance characteristics on track and off road.
• Proven Upper A-Arm Design — The upper A-arm benefits from RPM's experience with successful suspension designs refined through years of competitive racing and demanding RC use, ensuring an upper support structure capable of withstanding extreme impacts and stress.
• HPI Baja-Inspired Lower A-Arm — The lower A-arm employs a cross-section design derived from RPM's proven 1/5 scale HPI Baja A-arms, demonstrating this geometry has been battle-tested in one of the most demanding RC categories available, so you know they're genuinely tough.
• Enhanced Ground Clearance — These suspension arms offer better ground clearance than the stock Traxxas A-arms, which helps you navigate obstacles, bash over rough terrain and maintain consistent suspension geometry even when the truck gets fully compressed.
• Double Support Beam Construction — The lower arms feature a double support beam design that spreads impact energy over a larger surface area, preventing hard hits from causing catastrophic failure and significantly reducing the likelihood of breakage during aggressive driving.
• Universal Fit Design — These A-arms are manufactured as universal components, meaning they fit on any corner of your truck without concern about orientation or specific mounting points, eliminating confusion and reducing the need to purchase different parts for different positions.
• Engineering-Grade Nylon Construction — Moulded from RPM's signature blend of incredibly tough engineering-grade nylons, these A-arms deliver the perfect balance of strength, weight and resilience, allowing them to flex slightly under extreme loads rather than snapping completely.
• Made in the USA — These components are manufactured in the United States to RPM's exacting quality standards, ensuring consistency, reliability and support from a company deeply embedded in the RC hobby community.
• Industry-Leading Warranty — RPM backs every set of these A-arms with their industry-leading limited lifetime warranty against breakage, giving you complete peace of mind and worry-free performance you can genuinely count on.

Technical Performance

These suspension arms represent a carefully engineered solution to the durability challenges faced by X-Maxx owners. Each package contains one upper A-arm and one lower A-arm, requiring four packages total to outfit your complete vehicle with fresh suspension components on all four corners. The upper A-arm utilises design principles proven through years of successful RPM builds, providing reliable support for the steering geometry and vertical load of your X-Maxx. The lower A-arm benefits from engineering derived from RPM's 1/5 scale HPI Baja A-arms, cross-section designs that have proven themselves in one of the most demanding off-road racing categories available. The double support beam on the lower arms is a critical feature that distributes impact forces across a wider structural area, preventing concentrated stress points that would lead to breakage under hard landings, high-speed bashing and aggressive cornering. RPM's engineering-grade nylon formulation provides the ideal material properties for RC suspension components: sufficient strength to withstand the punishment delivered by an 8S LiPo powered monster truck, yet with enough flexibility to absorb impacts without shattering. These arms are also lighter than their stock counterparts, which directly translates to improved acceleration, better handling response and more precise steering inputs. The universal fit design means you don't need to worry about which arm goes where, simply install them on all four corners and enjoy immediate improvements in suspension durability and performance across your entire vehicle setup.

Frequently Asked Questions

• How many A-arm packages do I need to buy for my Traxxas X-Maxx? — You will need four packages of RPM82352 A-arms to completely outfit your X-Maxx, as each package contains one upper and one lower A-arm, and your truck has four corners. If you're replacing all suspension arms at the same time (recommended for consistency), ensure you purchase four of these packages.
• Can I mix and match RPM A-arms with stock Traxxas A-arms? — While RPM A-arms are engineered to be stronger and lighter than stock, it is recommended to upgrade all four corners simultaneously for optimal suspension geometry, handling characteristics and balanced performance across your entire truck.
• Will these A-arms fit my X-Maxx immediately or do I need to modify anything? — When used with the X-Maxx (using either stock or RPM A-arms), some minor modification of the A-arms is required for proper fitment. RPM includes detailed instructions with each package to guide you through the necessary adjustments, which are straightforward for most experienced RC builders.
• What makes these A-arms stronger than stock? — RPM engineers analysed extensive photographic evidence of stock A-arm failures to identify weak points, then completely redesigned the geometry and structure. The upper A-arm uses proven designs from successful RPM builds, whilst the lower A-arm incorporates cross-section engineering derived from RPM's 1/5 scale HPI Baja A-arms, which are battle-tested in extreme racing conditions. The double support beam on lower arms spreads impact energy over a larger area, preventing concentrated failure points.
• Are these compatible with my existing Traxxas suspension components? — Yes, RPM 82352 A-arms replace the upper A-arm from stock Traxxas #7729 and replace the lower A-arms from stock Traxxas #7730 and #773, making them direct replacements for your existing suspension. They are also compatible with other RPM A-arm variants including RPM #82354 and RPM #82355.
• What colour options are available for the RPM X-Maxx A-arms? — RPM offers these A-arms in three striking colours: Black (RPM82352), Green and Blue, allowing you to match your preferred colour scheme or coordinate with your truck's body colour and overall aesthetic.
• Are these A-arms lighter than stock and why does that matter? — Yes, RPM 82352 A-arms are lighter than stock Traxxas components whilst remaining significantly stronger, which improves your X-Maxx's acceleration response, handling characteristics and overall performance by reducing unsprung weight that the suspension must manage during cornering, acceleration and deceleration.
• Is this suitable for beginners to RC? — These A-arms are suspension upgrade components intended for owners of an existing Traxxas X-Maxx who are seeking improved durability and performance. They are not a complete RTR (ready to run) product, but rather replacement parts for users with basic to intermediate RC building and maintenance experience. If you're new to RC and considering an X-Maxx purchase, these represent an excellent upgrade to invest in after your initial purchase.
• What is RPM's warranty on these A-arms? — RPM backs these A-arms with their industry-leading limited lifetime warranty against breakage, providing comprehensive coverage for defects in materials and workmanship, giving you confidence in your purchase and long-term reliability.
