RPM Front A-arms for Traxxas Rustler Stampede Slash 2WD Blue RPM80245

Overview

The RPM Elec. Rustler & Stampede Front Arms in blue are precision-engineered suspension components designed specifically for electric Traxxas RC vehicles. Whether you're a serious RC competitor or a weekend basher looking to upgrade your RC car in the UK, these front A-arms represent a significant performance and durability enhancement over stock components. RPM has built a world-renowned reputation for producing some of the toughest aftermarket RC parts available, and these front arms exemplify that commitment to quality and performance.

If you own a Traxxas Slash 2WD, electric Rustler, electric Stampede 2WD, or Nitro Slash, upgrading to RPM front A-arms is one of the most impactful suspension modifications you can make. These parts are engineered to withstand serious abuse during high-speed runs, aggressive cornering, and hard landings that are inevitable in RC bashing. The front suspension is critical to your vehicle's handling, stability and durability, making it essential to use quality components that won't fail when you need them most. RC enthusiasts across the UK consistently choose RPM parts because they know they'll last longer and perform better than cheap alternatives.

What makes these front A-arms special is that RPM managed to reduce weight while actually increasing strength—a rare engineering achievement. These arms are nearly 25% lighter than the stock Traxxas components they replace, which means less unsprung weight affecting your suspension geometry and responsiveness. Less weight means faster acceleration, quicker deceleration, improved handling precision, and ultimately better lap times whether you're racing or just having fun at your local RC track.

Key Features

• Nearly 25% weight reduction over stock — RPM has engineered these front A-arms to shed unwanted unsprung weight compared to the original Traxxas #3631 components. This lighter design translates directly to improved suspension response, faster weight transfer during cornering, and better overall vehicle dynamics. Every gram matters in RC racing and bashing, and this significant weight saving gives you a genuine performance advantage.
• World-renowned breakage warranty — RPM stands behind their products with an industry-leading warranty that gives you peace of mind. If your RPM front arms break during normal use, RPM will replace them. This warranty protection demonstrates RPM's confidence in their engineering and materials, and means you can push your RC car hard without worrying about warranty issues when parts fail.
• Increased droop travel clearance — The outer portions of these A-arms feature enhanced clearance areas that allow dramatically increased droop travel when used with RPM oversized bearing carriers (RPM #80372 and RPM #80382). This means your suspension can extend further without binding, allowing for better compliance over rough terrain and more consistent handling across varied track conditions.
• Trademark angled leading and trailing edge design — RPM has moulded these A-arms with distinctive angled leading and trailing edges that reduce frontal edge mass. This clever design allows the A-arms to ride up and over tall obstacles smoothly instead of slamming into them and potentially breaking. The geometry helps your RC car maintain momentum through technical sections and reduces the shock loading on suspension components.
• Exceptional rigidity and stability — These A-arms are engineered to be extremely rigid, which means they flex minimally during aggressive driving. The rigidity translates to superior ride quality, consistent handling characteristics across the entire track, and stability during high-speed cornering. Rigid suspension arms maintain proper suspension geometry better than flexible alternatives, keeping your vehicle planted and predictable.
• Available in blue and multiple colours — These front A-arms come in blue as shown, but are also available in black, green, red, and pink. Having colour options means you can match your RC car's body colour scheme for a cohesive, professional appearance. The blue finish is a popular choice for Traxxas RC vehicles and looks particularly striking on Slash 2WD and Rustler models.
• Sold in pairs — Each purchase includes a complete pair of front A-arms (left and right), everything you need to upgrade both sides of your front suspension simultaneously. You don't need to buy two separate products or hunt for matching components—everything is included.
• Direct replacement for stock Traxxas #3631 — These RPM arms are engineered as a direct replacement for the original Traxxas front A-arms, meaning fitment is guaranteed. You can simply remove your stock arms and install the RPM versions without modification or additional parts required. This straightforward upgrade is perfect for anyone wanting to improve their RC car's suspension without complex modifications.

Technical Performance

The RPM front A-arms represent a substantial engineering upgrade over the stock Traxxas components. Built from durable composite materials, these arms are engineered to withstand the punishment of serious RC bashing and racing. The nearly 25% weight reduction compared to stock (#3631) arms is achieved through intelligent material selection and engineering design that maintains full structural integrity whilst shedding unnecessary mass. This weight saving occurs in the unsprung portion of the suspension, meaning it directly improves suspension response and vehicle handling characteristics. The increased clearance areas in the outer arm sections allow compatibility with RPM's oversized bearing carriers (RPM #80372 for Slash 2WD and RPM #80382 for electric Stampede and Rustler), enabling greater droop travel for more aggressive suspension setups. The trademark angled leading and trailing edge geometry reduces the frontal profile and edge mass, allowing the arms to compress and flex over obstacles rather than impacting them directly. The overall rigidity of these arms ensures consistent handling across all track conditions and driving styles. Whether you're bashing in muddy fields or competing on a smooth indoor track, these arms will maintain their geometry and provide predictable handling. The engineering philosophy behind these arms prioritises durability without compromise—these are genuine performance parts that will outlast multiple stock replacements, making them exceptional value for any serious RC enthusiast in the UK.

Frequently Asked Questions

• Will these RPM front arms fit my Traxxas Rustler or Stampede? — Yes, these arms are specifically designed for the electric versions of the Traxxas Rustler and Stampede 2WD. They replace the stock Traxxas #3631 front A-arms directly. However, they will not work on the nitro versions of the Rustler and Stampede, only the electric models. If you own a Slash 2WD or Nitro Slash, these arms are also fully compatible with those vehicles.
• How much weight do these RPM arms save compared to stock? — RPM front A-arms are nearly 25% lighter than the original Traxxas stock components. This significant weight reduction in the unsprung portion of your suspension improves handling response, acceleration, and cornering performance. The weight saving is achieved without sacrificing any structural integrity—these arms are actually stronger than stock despite being lighter.
• Are these front arms durable and backed by a warranty? — Absolutely. RPM front A-arms are backed by RPM's world-renowned breakage warranty, which means if your arms break, RPM will replace them.
