RPM Front Right A-Arms for Traxxas E-Revo 2.0 Blue RPM81465

Overview

The RPM Blue Front Right A-Arms for E-Revo Brushless (RPM81465) are premium suspension upgrades designed specifically for the Traxxas E-Revo 2.0 platform. Whether you're a dedicated basher, weekend racer, or serious RC enthusiast in the UK looking to enhance your brushless RC truck, these front right a-arms deliver a significant performance and durability upgrade over factory stock components. RPM has engineered these suspension arms to be tougher, lighter and more efficient than the original Traxxas specification, making them an essential upgrade for anyone serious about maximising their E-Revo 2.0's potential.

As a leading UK RC retailer, we recognise that suspension quality directly impacts handling, durability and overall performance in ready-to-run RC vehicles. RPM's commitment to manufacturing excellence—all parts are produced in the USA using engineering-grade nylon compounds—ensures that these a-arms will withstand the rigours of off-road bashings, competitive track sessions, and high-speed terrain work. The blue colour finish provides excellent visibility on track and stands out against soil and grass, making it easier to spot your RC car during intense driving sessions.

These front right a-arms replace the stock Traxxas #8631 components and are sold as one complete upper and one lower a-arm pair, giving you everything needed for a straightforward suspension upgrade on your E-Revo 2.0 brushless platform.

Key Features

• 5 Grams Per Side Weight Reduction — RPM a-arms weigh in at 5 grams less than stock per side, delivering a total weight loss of 10 grams when fitted to the front of your RC truck. This weight saving improves acceleration, reduces unsprung mass and helps optimise the vehicle's centre of gravity, resulting in sharper handling and quicker response to throttle input on demanding UK terrain.
• Superior Strength vs Stock Components — While Traxxas has beefed up the E-Revo 2.0 suspension arms compared to previous generations, RPM versions are considerably tougher and more durable. The engineering-grade nylon blend used in RPM's manufacturing process resists cracking, splitting and stress failure far better than factory plastic, meaning fewer broken a-arms during high-impact bashings or competitive racing.
• Optimised Angled Geometry Design — RPM's angled leading and trailing edges are not merely aesthetic; they cut through the air cleaner and more efficiently, reducing aerodynamic drag during high-speed runs. These same angled edges also allow the a-arms to slip up and over tall objects with reduced chance of direct impact, keeping your RC truck mobile when traversing rough terrain and avoiding sudden stops from catching obstacles.
• USA Manufacturing with Lifetime Warranty — All RPM a-arms are manufactured in the United States to strict quality standards and come with a limited lifetime warranty against breakage. This demonstrates the manufacturer's confidence in their product and provides peace of mind for UK buyers investing in suspension upgrades.
• Blue Colour Finish — The striking blue colour provides excellent visual contrast, making your RC car easier to spot during outdoor driving sessions and adding visual appeal to your Traxxas E-Revo 2.0 build.
• Deeper Pivot Ball Hole Design — RPM a-arms feature a deeper pivot ball hole than stock specifications to prevent the pivot ball from bottoming out, ensuring proper suspension geometry and longer component lifespan.
• Engineered Nylon Blend Construction — The indestructible blend of engineering-grade nylons provides the perfect balance of rigidity and impact absorption, ensuring these a-arms can handle the demands of aggressive driving without excessive flex or permanent deformation.

Technical Performance

The RPM81465 front right a-arms are engineered specifically for the Traxxas E-Revo 2.0 brushless platform, offering substantial performance improvements over stock suspension components. Constructed from an indestructible blend of engineering-grade nylons, these a-arms deliver superior strength whilst maintaining a 5-gram per side weight advantage over factory Traxxas parts—a total of 10 grams per pair. This weight reduction is particularly significant in RC vehicles, as it reduces unsprung mass and improves the truck's ability to respond to suspension movements and terrain changes. The angled leading and trailing edge geometry represents a significant engineering advantage: these edges don't simply reduce aerodynamic drag during high-speed runs, they also improve the a-arms' ability to traverse obstacles by allowing them to slip up and over tall objects with minimal risk of catching and stopping your truck mid-run. The deeper pivot ball hole design is a critical engineering feature that prevents the pivot ball from bottoming out during extreme suspension compression, maintaining proper suspension geometry and preventing stress-induced failures. RPM a-arms will not work with long travel (LT) style rockers, so ensure your E-Revo 2.0 is fitted with standard rocker geometry. Upper a-arms will not function in the lower roll-centre hinge pin hole and must be installed in their designated position. For optimal performance after installation, RPM recommends using their Camber Gauge (Part #70950) to verify camber angles, which should range from 0° to -3° depending on driving style and terrain, with front wheels matched to each other and rear wheels matched as a pair.

Frequently Asked Questions

• Will these RPM a-arms fit my Traxxas E-Revo 2.0 brushless RC truck? — Yes, the RPM81465 front right a-arms are designed specifically for the Traxxas E-Revo 2.0 and directly replace the factory Traxxas #8631 components. They are sold as one upper and one lower a-arm pair suitable for the front right position. Ensure your truck uses standard rocker geometry, not long travel (LT) style rockers, as RPM E-Revo 2.0 a-arms are not compatible with extended travel suspension setups.
• How much weight will I save by upgrading to RPM a-arms? — Each RPM a-arm is 5 grams lighter than the equivalent stock Traxxas component per side, delivering a total weight loss of 10 grams per pair. Whilst this may sound modest, weight reduction in RC vehicles has a measurable impact on acceleration, handling and the truck's ability to respond to suspension inputs.
• Are RPM a-arms more durable than stock Traxxas parts? — Absolutely. While Traxxas has upgraded the E-Revo 2.0 suspension arms, RPM versions are considerably tougher and more durable thanks to their engineering-grade nylon blend, which resists cracking and splitting far better than standard plastic. All RPM a-arms carry a limited lifetime warranty against breakage, reflecting the manufacturer's confidence in their durability.
• Do I need to buy both left and right a-arms, or can I buy them separately? — The RPM81465 is the front right a-arm. There is a separate part number for the front left a-arm (RPM81462). You can purchase them individually based on your needs, whether upgrading one side or completing a full front suspension replacement.
• What is the difference between RPM81462 and RPM81465? — RPM81462 is the front left a-arm, while RPM81465 is the front right a-arm. Both parts are designed to the same specification and performance standard; they are simply mirror images designed for their respective vehicle sides.
• Can I use the upper a-arm in any hinge pin hole position? — No. The upper a-arm must be installed in the upper roll-centre hinge pin hole only. Do not install the upper a-arm in the lower roll-centre hinge pin hole, as it will contact the outdrive of the axle and cause mechanical interference.
• How should I install the pivot ball correctly? — RPM a-arms feature a deeper pivot ball hole than stock. Thread the pivot ball into the a-arm until the pivot ball threads end exactly at the end of the a-arm. Do not bottom the pivot ball threads in the hole, as this will stress the a-arms and void your RPM warranty. Take care during assembly to follow this critical instruction.
• Should I adjust camber angles after installation? — Yes. Once your new a-arms are properly mounted on your truck, use an RPM Camber Gauge (Part #70950) to accurately check the camber angles of each wheel. Proper camber angles vary according to personal preference, ranging from 0° to -3°, but the front wheels should be identical to each other, and the same applies to the rear wheels. Make only slight changes at a time to the upper and lower pivot balls.
• Is this suitable for beginners? — These a-arms are suspension upgrade components designed to replace factory parts. While they are not difficult to install for anyone with basic RC mechanical knowledge, they are best suited to owners who are already familiar with their E-Revo 2.0 and want to enhance its performance and durability. Beginners may benefit from professional installation at an RC hobby shop.
• Are these a-arms available in other colours? — Yes, RPM81465 front right a-arms are available in blue. A black version is also offered under part number RPM81462, allowing you to choose the colour that best suits your RC truck's aesthetic.
• Will these a-arms improve my E-Revo 2.0's handling? — Yes. The weight reduction, superior durability, and optimised geometry of RPM a-arms combine to enhance handling response, improve acceleration, and provide more predictable suspension behaviour during aggressive driving and high-speed bashings.
