Traxxas Long-Travel Rocker Arm Set 120-T Suspension Upgrade TRX5356

Overview

The Traxxas Rocker arm Set, Long travel (120-T) is a premium suspension upgrade designed for RC enthusiasts looking to dramatically improve their vehicle's off-road performance. Whether you're a dedicated basher exploring the rough terrain of the British countryside or a serious competitor pushing your RC car to its limits, this long-travel rocker arm set delivers the suspension travel you need to conquer the largest bumps and obstacles with confidence. Long-travel suspension systems are essential upgrades for anyone wanting to transform their ready to run RC car into a capable off-road machine that can handle extreme terrain with exceptional comfort and control.

This is a specialist suspension component that replaces the standard rocker arm assembly on compatible Traxxas models, significantly extending the suspension geometry to allow for greater vertical wheel movement. By increasing suspension travel, you gain the ability to maintain traction over rough ground, absorb massive impacts without bottoming out, and achieve the plushest ride quality possible from your RC vehicle. The engineering behind long-travel suspension is precisely what separates casual weekend bashers from serious RC hobbyists who demand maximum performance and reliability from their equipment.

The rocker arm set is engineered by Traxxas, a manufacturer renowned worldwide for producing high-quality RC cars and components trusted by competitors and enthusiasts across the UK and globally. This upgrade represents a straightforward yet transformative way to enhance your existing RC platform without requiring a complete chassis replacement, making it an economical choice for those seeking to unlock their vehicle's true potential.

Key Features

• Long-travel suspension geometry (120-T) — The long-travel rocker arm design increases overall suspension travel dramatically, allowing your RC car's wheels to move vertically through a much greater range of motion, which means bigger bumps are absorbed more effectively and you maintain better traction on uneven terrain.
• Plush ride quality — The extended suspension travel creates a smoother, more compliant riding experience that absorbs large impacts without harshness, protecting both your vehicle's components and maintaining consistent speed through rough sections that would otherwise cause loss of control.
• Larger bump absorption capability — The 120-T specification denotes the extended travel capacity, enabling the suspension to soak up the largest obstacles your local riding spots can throw at you, from rocky trails to heavily rutted ground and substantial jump landings.
• Increased ground clearance potential — With greater suspension articulation, your RC car achieves improved ground clearance during compression, reducing the risk of high-centering on rocks and obstacles that would normally get caught on the chassis.
• Straightforward installation — The rocker arm set is designed for bolt-on installation on compatible Traxxas platforms, making this upgrade accessible even to those without extensive mechanical experience, though basic tools and mechanical knowledge are recommended.
• Requires compatible push rods — The long-travel rocker arms work in concert with Traxxas push rods models 5318 or 5318X (sold separately), which are specifically engineered to match the extended suspension geometry and ensure proper suspension kinematics.

Technical Performance

The Traxxas Rocker arm Set, Long travel (120-T) represents a fundamental advancement in suspension engineering for compatible RC platforms. This component is manufactured to precise specifications using durable materials capable of withstanding the demanding forces created by high-speed running, aggressive driving, and landing impacts from jumps. The long-travel geometry significantly alters your vehicle's suspension kinematics, providing substantially greater vertical wheel travel than standard rocker arms whilst maintaining proper suspension progression and anti-squat characteristics. When paired with the correct push rods (5318 or 5318X), the suspension system delivers superior bump absorption across all terrain types, from smooth tracks to rocky trails and heavily wooded off-road courses throughout the UK. The extended travel capacity is particularly beneficial for high-speed running where suspension compliance becomes critical for maintaining speed through rough sections, and for aggressive rock crawling where maximum articulation is essential for scaling obstacles. The engineering allows your RC car to maintain better traction and stability in situations where standard suspension would compress fully and lose effectiveness. Build quality is consistent with Traxxas's reputation for manufacturing components that tolerate punishment from serious bashers and competitors alike, ensuring years of reliable performance when properly maintained.

Frequently Asked Questions

• What does 120-T mean on the long-travel rocker arm set? — The 120-T designation specifies the extended suspension travel capacity of this particular rocker arm configuration. This numbering indicates the geometry has been optimised for maximum vertical wheel movement compared to standard rocker arms, enabling superior bump absorption and a much plushier ride quality during aggressive driving.
• Which push rods do I need for this long-travel rocker arm set? — You must use either Traxxas push rod model 5318 or 5318X in conjunction with these long-travel rocker arms. These specific push rods are engineered to match the extended suspension geometry and ensure the suspension operates with correct kinematics. Using standard push rods with long-travel rocker arms will result in improper suspension geometry and poor handling characteristics.
• Is this suspension upgrade suitable for beginners to RC cars in the UK? — Whilst the rocker arm set itself is not particularly complex, this is an intermediate upgrade best suited to RC enthusiasts who already understand suspension geometry and have basic mechanical skills. If you're new to RC cars, it's recommended to become familiar with your vehicle's standard setup first before progressing to performance upgrades like this. Alternatively, seek advice from experienced RC shop staff who can explain the benefits and installation requirements.
• What vehicles are compatible with this rocker arm set? — The long-travel rocker arm set is designed for specific Traxxas platforms that utilise this suspension system. Check your vehicle's documentation or consult with RC Model Shop staff to confirm compatibility before purchasing, as using these rocker arms on incompatible platforms will not function properly and may damage your vehicle.
• How much does suspension travel increase with this upgrade? — Compared to standard rocker arms, the 120-T long-travel design provides a significant increase in suspension travel, though the exact measurement depends on your specific vehicle platform. The practical benefit is immediately noticeable during driving — larger bumps are absorbed more effectively, rough terrain becomes easier to traverse at higher speeds, and overall ride quality is noticeably plushier.
• Can I install this myself, or do I need a professional mechanic? — Installation requires basic mechanical knowledge and hand tools but is generally straightforward for anyone comfortable working on RC vehicles. The rocker arms bolt onto your existing suspension components using standard fasteners. If you're uncertain about the process, most UK RC shops including RC Model Shop can provide guidance or installation support.
• What is the difference between this long-travel set and standard rocker arms? — Standard rocker arms provide adequate suspension travel for general driving, but long-travel rocker arms like this 120-T set dramatically increase the available suspension movement. This translates to better bump absorption, improved traction on rough terrain, greater ground clearance during compression, and a more compliant ride quality that allows you to maintain higher speeds through rough sections without losing control or bottoming out.
