RPM Front Arms Suspension Kit Black Traxxas Slash Rustler Stampede RPM80242

Overview

The RPM Front Arms in Black are essential upgrade components for your Traxxas Slash 2WD, Nitro Slash, electric Rustler, or electric Stampede 2WD RC car. These suspension arms represent a significant performance enhancement over factory-standard parts, delivering improved durability, reduced weight, and enhanced handling characteristics that will transform your driving experience. Whether you're a dedicated RC enthusiast in the UK looking to optimise your stadium truck or short course truck setup, or a weekend basher seeking more reliable suspension components, these arms are engineered to withstand the toughest abuse whilst maintaining exceptional rigidity and stability across any terrain.

RPM has established itself as a leader in aftermarket RC suspension components, and these front A-arms exemplify that commitment to quality and performance. Built using advanced manufacturing techniques and premium materials, these arms are nearly 25% lighter than the original Traxxas stock components they replace, which directly translates to reduced unsprung weight—a critical factor in improving ride quality, handling precision, and overall vehicle responsiveness. The weight reduction doesn't come at the expense of strength; in fact, RPM's design is backed by their world-renowned breakage warranty, giving you complete peace of mind when pushing your RC car to its limits.

These arms are sold as a pair and are available in multiple colours including Black, Green, Blue, Red, and Pink, allowing you to customise your RC car's appearance to match your personal style or team colours. The engineering philosophy behind RPM suspension components focuses on real-world performance improvements that serious RC competitors and dedicated enthusiasts genuinely value.

Key Features

• Nearly 25% Weight Reduction — By removing unnecessary material and optimising the design, RPM has shaved significant unsprung weight from these arms compared to the stock Traxxas #3631 parts they replace. Reducing unsprung weight is one of the most effective ways to improve suspension compliance, traction, and overall handling characteristics, meaning your RC car will feel more responsive and planted through corners and over jumps.
• Trademark Angled Leading and Trailing Edges — RPM's distinctive design features precisely angled leading and trailing edges that reduce frontal edge mass whilst improving the arms' ability to ride up and over tall obstacles rather than slamming into them. This design philosophy translates to smoother handling over rough terrain, reduced shock loading on suspension components, and better overall durability in high-speed bashful driving scenarios.
• Exceptional Rigidity and Stability — These arms are engineered to be extremely rigid, which ensures superior ride quality and stability over the roughest tracks and terrain. The increased structural integrity provides consistent handling characteristics whether you're racing on prepared tracks or driving through rocky off-road environments, delivering the predictability and confidence that drivers demand.
• Increased Clearance and Droop Travel — The outer portion of these A-arms features increased clearance areas that allow greater droop travel when used in conjunction with RPM oversized bearing carriers (RPM #80372 and #80382). This enhanced suspension geometry gives you additional tuning flexibility and improved suspension performance, particularly in aggressive driving scenarios or when running on extreme terrain.
• World-Renowned Breakage Warranty — RPM backs these arms with their famous breakage warranty, which reflects the manufacturer's confidence in the product's durability and performance. This warranty provides essential peace of mind, knowing that if you experience any defects in materials or workmanship under normal use, RPM will support you.
• Compatible with Multiple Traxxas Models — These arms fit all versions of the Traxxas Slash 2WD, Nitro Slash, electric Rustler, and electric Stampede 2WD, making them a versatile upgrade option if you run multiple vehicles in this platform family. The direct replacement design (replaces stock Traxxas #3631) means installation is straightforward, with no modification required.
• Multiple Colour Options Available — Beyond this Black variant, you can choose from Green, Blue, Red, or Pink to match your personal aesthetic preferences or coordinate with other components on your RC car. Colour customisation allows you to build a truly personalised machine that reflects your style.

Technical Performance

The RPM Front Arms represent a comprehensive engineering solution to one of the most critical suspension components in short course trucks and stadium trucks. The manufacturing process utilises high-quality polymer materials that deliver an exceptional strength-to-weight ratio, enabling RPM to achieve that remarkable 25% weight reduction whilst actually improving durability compared to the original Traxxas parts. The angled leading and trailing edge design is not merely cosmetic—it's a functional element that reduces the effective mass of the arm's leading edge, allowing it to deflect more smoothly over obstacles and reducing the sharp impacts that cause suspension component failure. The increased clearance areas machined into the outer portions of the arms provide dedicated space for suspension droop, which is particularly important when upgrading to RPM oversized bearing carriers. This enhanced geometry allows the suspension to use its full range of travel more effectively, improving traction in rough conditions and providing better ground clearance during aggressive driving. The extreme rigidity of the arm structure ensures that suspension geometry remains consistent throughout the range of motion, preventing flex that would otherwise create unpredictable handling. These arms are engineered from the ground up to handle the demanding requirements of modern RC competition whilst remaining accessible to enthusiast-level drivers who enjoy reliable, durable components that simply work better than factory alternatives.
