RPM Traxxas Summit Revo Front Left A-Arms Black Suspension Component RPM70372

Overview

The RPM TRAXXAS SUMMIT/REVO FRONT LEFT A-ARMS BLACK (RPM70372) represent a significant upgrade for owners of the Traxxas Summit and Revo RC vehicles. These precision-engineered suspension components are specifically designed to overcome the unique challenges posed by the Summit's extended T-Lock differential, delivering dramatically improved durability and suspension travel compared to standard stock parts. If you're running a Traxxas Summit or Revo and tired of constantly replacing broken suspension components, these RPM front left A-arms offer an exceptional solution that will transform your RC experience.

RPM has responded to overwhelming customer demand by developing these front left A-arms specifically for the Summit platform. The existing RPM right front A-arms (reference RPM #80212 & #80215) have long been compatible with the Summit, but the left side presented a unique engineering challenge due to the extended T-Lock differential design. With this innovative new product, RPM has solved that problem entirely, allowing Summit and Revo owners across the UK to enjoy matching front left and right suspension components without compromise. These A-arms are manufactured to the same exacting standards that have made RPM a trusted name in the RC hobby sector for years.

Whether you're a serious RC racer competing at the weekend, a dedicated basher enjoying high-speed runs across varied terrain, or an enthusiast looking to build the ultimate Traxxas platform, these front left A-arms will elevate your RC car UK setup to the next level. The combination of advanced materials, superior engineering, and proven durability makes this an essential upgrade for any Summit or Revo owner seeking maximum performance and reliability.

Key Features

• Engineered for Traxxas Summit and Revo compatibility — These A-arms are specifically designed to work with both the Traxxas Summit and Revo platforms, with the left side engineering solved to clear the extended T-Lock differential that makes these vehicles unique. This precision fit ensures seamless integration without modification.
• Revamped cross-brace design — The innovative cross-brace geometry has been completely redesigned to clear the Summit's T-Lock differential while maintaining full suspension travel range. This breakthrough design delivers full articulation and flexibility that stock parts simply cannot provide.
• Full suspension travel capability — By accommodating the T-Lock differential design, these A-arms allow the complete range of suspension movement, enabling better traction, improved handling characteristics, and superior performance over rough terrain and obstacles.
• Exceptional durability improvement — A-arms are critical suspension components that take significant abuse during RC driving. These RPM components significantly improve overall suspension durability compared to stock plastic parts, meaning fewer replacements and more time enjoying your vehicle.
• Indestructible engineering-grade nylon construction — RPM uses a strictly formulated blend of engineering-grade nylons specifically developed for RC applications. These materials provide outstanding impact resistance, flexibility, and longevity far exceeding standard plastic compounds.
• Manufactured in the USA with lifetime warranty — Every single RPM front left A-arm is manufactured in the United States to exacting quality standards, and each part carries RPM's limited lifetime warranty against breakage. This warranty demonstrates RPM's complete confidence in the durability of their products.

Technical Performance

The RPM TRAXXAS SUMMIT/REVO FRONT LEFT A-ARMS BLACK RPM70372 represent a quantum leap in suspension component engineering for brushless RC vehicles in this category. Built from indestructible engineering-grade nylon materials that RPM has perfected over years of development, these A-arms deliver the kind of impact resistance and flexibility that standard plastic suspension components simply cannot match. The critical innovation lies in the revamped cross-brace design that clears the Summit's extended T-Lock differential—a feature that had previously prevented left-side installation of aftermarket A-arms. This engineered solution maintains complete suspension travel throughout the full range of motion, ensuring that your vehicle benefits from improved traction and handling across all driving conditions. The material composition provides superior durability under the extreme stresses encountered during high-speed running, terrain bashing, and competitive racing. Whether you're pushing your ready to run RC vehicle to its limits or building an elite competition setup, these A-arms will withstand repeated impacts and harsh conditions that degrade standard components. RPM's American manufacturing ensures consistent quality control and adherence to exact specifications, whilst the limited lifetime warranty against breakage provides peace of mind and demonstrates the manufacturer's confidence in their product. For owners of the Traxxas Summit or Revo looking to eliminate suspension component failures and achieve maximum performance, these front left A-arms represent essential engineering that transforms the vehicle's capability.

Frequently Asked Questions

• Will these A-arms fit my Traxxas Summit without modification? — Yes, these A-arms are specifically engineered for direct bolt-on installation on the Traxxas Summit without any modification required. The cross-brace has been redesigned to clear the extended T-Lock differential on the left side, solving the compatibility issue that prevented earlier RPM A-arms from fitting the Summit.
• Are these suitable for both Traxxas Summit and Revo vehicles? — These front left A-arms are compatible with both the Traxxas Summit and the Revo. The right side A-arms (RPM #80212 & #80215) have long worked with both platforms, and these left A-arms now provide matching left-side components for both vehicles, allowing you to upgrade your complete front suspension.
• What makes RPM A-arms better than stock plastic suspension components? — RPM A-arms are constructed from engineering-grade nylon that is far more impact resistant and durable than standard plastic. Stock suspension components frequently break under the stresses of RC driving, whereas RPM components significantly improve durability and reduce replacement frequency. The engineered materials provide better flexibility and shock absorption, protecting other suspension components from damage.
• Do I need to replace both left and right A-arms, or can I use these with stock right A-arms? — You can use these left A-arms with your existing stock right A-arms if desired, though for optimum performance and durability, upgrading both left and right sides simultaneously is recommended. The complete set of RPM A-arms (front left and front right) provides the most comprehensive suspension upgrade.
• What is the limited lifetime warranty coverage? — RPM's limited lifetime warranty covers breakage of the A-arms due to normal use. This warranty demonstrates RPM's confidence in their product durability and provides protection against manufacturing defects. Warranty terms should be reviewed at the point of purchase for specific coverage details.
• How do these A-arms improve my vehicle's performance? — By allowing full suspension travel range and resisting impact damage that would break stock components, these A-arms enable better traction, improved handling characteristics, and more consistent performance across varied terrain. You'll experience better articulation over obstacles, reduced suspension binding, and improved overall vehicle responsiveness compared to damaged stock components.
• Are these suitable for off-road bashing as well as competition racing? — Yes, these A-arms are engineered for both high-intensity competitive racing and aggressive weekend bashing. The durable materials and proven engineering make them ideal for any driving style, from serious competition to recreational terrain exploration with your ready to run RC vehicle.
• Where are RPM products manufactured? — All RPM molded suspension components, including these front left A-arms, are manufactured in the United States to exacting quality standards. American manufacturing ensures consistent quality control and adherence to precise specifications.
