Key Features

• Heavy-Duty Composite Construction — These suspension arms utilise Traxxas's latest proprietary composite material engineered specifically for extreme durability and high-load applications. This advanced composite offers the perfect balance of strength and flex, resisting breakage even in cold weather conditions when other materials become brittle. Whether you're landing hard jumps at the skate park or launching off ramps, these arms are built to absorb and withstand the punishment that RC vehicles endure during aggressive bashing sessions.
• Rear Left Position (Lower and Upper Combo) — This product includes both upper and lower suspension arm components for the rear left position of your vehicle, providing a complete replacement solution for one side of the rear suspension. The inclusion of both pieces in a single product means you get a matched pair engineered to work together perfectly, eliminating compatibility concerns and ensuring optimal suspension geometry.
• Adjustable Wheelbase Design — The adjustable wheelbase feature allows you to modify your vehicle's track width and suspension geometry to suit different driving conditions and personal preferences. This adjustability is invaluable for tuning your RC car's handling characteristics, whether you need more stability for high-speed runs or different handling for tight cornering and technical courses. Fine-tuning wheelbase geometry can dramatically improve your vehicle's performance on various terrains, from smooth tarmac to loose gravel and muddy off-road conditions.
• Genuine Traxxas Quality and Compatibility — As an official Traxxas component, these suspension arms are manufactured to exact factory specifications and are guaranteed to fit perfectly with compatible Traxxas vehicles. The red colour matches other Traxxas coloured accessories, allowing you to build a cohesive, professional-looking setup. You're not just buying a replacement part; you're buying peace of mind knowing you have factory-matched components that will integrate seamlessly with your RC vehicle.
• Designed for Extreme Performance — These arms are specifically engineered to handle the demands of extreme RC driving, whether that involves high-speed bashing, off-road adventures, or competitive track racing. The durability characteristics mean fewer broken parts and more time enjoying your hobby rather than troubleshooting equipment failures. For UK RC car enthusiasts who demand the best, these suspension arms deliver the reliability and performance you need.

Technical Performance

The TRX8634R suspension arms represent the pinnacle of Traxxas suspension engineering, employing proprietary composite materials that have been refined through years of competitive racing experience. The heavy-duty construction delivers exceptional durability without sacrificing the slight flex characteristics necessary to absorb impacts and prevent catastrophic breakage. This is particularly important in the variable UK climate, where cold weather can make standard materials brittle and prone to shattering. The composite material used in these arms maintains its structural integrity across a wide temperature range, making them suitable for year-round RC activities. The dual-component design (upper and lower arms) works together to provide optimal suspension geometry, and the adjustable wheelbase feature allows you to dial in the perfect setup for your driving style and the terrain you're tackling. Whether you're running a brushless or brushed RC vehicle, these suspension arms can be paired with any compatible Traxxas chassis to create a setup that performs at the highest levels. The engineering behind these arms reflects Traxxas's commitment to quality and performance, making them an essential upgrade for anyone serious about RC car performance and reliability. The rear left position design ensures perfect symmetry when paired with the right-side equivalent, creating balanced suspension geometry that translates directly into improved handling, stability, and predictability during driving.

Frequently Asked Questions

• What vehicles are these Traxxas suspension arms compatible with? — These TRX8634R rear left suspension arms are designed for specific Traxxas models featuring adjustable wheelbase suspension systems. To confirm compatibility with your specific vehicle, check your vehicle's documentation or contact RC Model Shop's expert team who can advise on fitment for your particular RC car.
• Can I use just one arm or do I need to buy both upper and lower? — This product includes both the upper and lower arm components together as a matched set for the rear left position. Traxxas manufactures them this way to ensure perfect compatibility and suspension geometry. If you need arms for both sides of your vehicle, you would need to purchase separate left and right kits.
• Why are these called heavy-duty suspension arms? — The heavy-duty designation refers to the advanced proprietary composite material Traxxas uses, which is specifically engineered for high-load applications and extreme durability. This material can withstand harder impacts, bigger jumps, and more aggressive driving than standard suspension arms, making it ideal for serious bashers and competitive drivers who want reliability they can depend on.
• Will these arms work in cold weather? — Yes, one of the key advantages of Traxxas's proprietary composite material is its ability to maintain flexibility and strength even in cold weather conditions. Standard materials can become brittle in low temperatures, but these arms are engineered to resist breakage year-round, making them perfect for UK RC enthusiasts who enjoy driving throughout the winter months.
• What is meant by adjustable wheelbase? — Adjustable wheelbase means these suspension arms allow you to modify the distance between your vehicle's front and rear wheels (the wheelbase). This tuning feature affects handling characteristics, stability, and cornering performance. A longer wheelbase typically provides more stability, whilst a shorter wheelbase can improve manoeuvrability—you can adjust these arms to find the perfect setting for your driving style and track conditions.
• How long do these suspension arms typically last? — With proper maintenance and care, these heavy-duty Traxxas suspension arms will last considerably longer than standard arms thanks to their advanced composite construction. However, they are wear items that may eventually need replacement depending on your driving intensity. The durability advantages mean you'll replace them far less frequently than cheaper alternatives, making them a smart long-term investment for serious RC car enthusiasts.
• Are these arms available in other colours? — These TRX8634R arms are available in red. Traxxas produces suspension arms in multiple colours across their range, allowing you to match your vehicle's overall aesthetic. If you're looking for alternative colours, RC Model Shop can advise on what's currently available in stock or can order alternatives through our Traxxas supplier relationships.
