Overview
The Traxxas Suspension links, Front lower, Blue (2 pcs) represent a premium upgrade component specifically engineered for the TRX-4 Long Arm Lift Kit suspension system. These front lower suspension links are an essential part of maximising the performance and capability of your Traxxas TRX-4 crawler, whether you're tackling challenging terrain at your local trail site or exploring rocky landscapes across the UK. Built with precision engineering and robust materials, these suspension components are designed to withstand the demands of serious off-road RC crawling whilst providing the adjustability and durability that experienced enthusiasts demand from their kit.
If you're already running a TRX-4 with the Long Arm Lift Kit or planning to upgrade your setup, these front lower suspension links are a direct replacement or upgrade component that will enhance your truck's performance characteristics. The distinctive blue powder-coated finish not only looks great on your rig but also provides protection against corrosion and wear. Whether you're a weekend basher exploring green lanes, a competition crawler pushing your truck to its limits, or an RC enthusiast in the UK looking to dial in the perfect setup, these suspension links deliver the quality and performance you need.
Traxxas has built a reputation for engineering durability and precision into every component, and these front lower suspension links are no exception. As part of the TRX-4's legendary suspension architecture, these links work in harmony with the Long Arm Lift Kit to provide superior articulation, better weight distribution, and improved obstacle-climbing ability across all terrain types.
Key Features
- Precision-engineered steel construction — The suspension links are manufactured from high-quality powder-coated steel, which provides exceptional strength and rigidity whilst resisting corrosion and weathering during extended off-road use, ensuring your investment remains protected and performs consistently over time.
- Hollow ball assemblies — Each link features hollow ball joints pre-assembled at the factory, which reduces unsprung mass and improves suspension responsiveness, allowing your TRX-4 to react more quickly to terrain changes and maintain better control over obstacles and uneven ground.
- Optimised 5x104mm dimensions — The specific sizing of these front lower links is precisely calculated for use with the Long Arm Lift Kit, ensuring perfect geometry and ride height that maximises the suspension's intended performance envelope and articulation capability.
- Blue powder-coat finish — The vibrant blue colour matches Traxxas' premium aesthetic whilst the powder coating provides a durable protective layer against dirt, mud, water, and UV exposure, keeping your TRX-4 looking sharp whilst maintaining component longevity.
- Complete pair included — You receive two suspension links in this package, which is exactly what you need for the front axle of your TRX-4, eliminating the need to purchase multiple items and ensuring matched components for balanced suspension performance.
- Direct compatibility with Long Arm Lift Kit — These links are specifically engineered for the Traxxas #8140X TRX-4 Long Arm Lift Kit, guaranteeing perfect fitment and optimal geometry integration with your existing suspension system.
Technical Performance
These front lower suspension links are engineered with the same precision and attention to detail that characterises all Traxxas upgrade components. The powder-coated steel construction provides the ideal balance between strength and weight, with the hollow ball assemblies minimising unsprung mass to improve suspension response and articulation. The 5x104mm dimension specification is not arbitrary—it has been precisely calculated to work seamlessly with the Long Arm Lift Kit geometry, ensuring correct suspension angles, ride height, and articulation characteristics across the full range of off-road terrain. The hollow ball joints are pre-assembled at the factory, saving you setup time whilst guaranteeing proper assembly and geometry. The powder coat finish is applied using industrial-grade processes that create a hard, corrosion-resistant surface capable of withstanding mud, water, stones, and all the punishment that UK trail running can deliver. Whether you're crawling rocky moorland, tackling forest tracks, or pushing your TRX-4 through extreme obstacles, these suspension links deliver the durability and performance you need. The blue finish is colour-matched to other Traxxas components, allowing you to create a cohesive, professional appearance across your entire rig.

Frequently Asked Questions
- Will these suspension links fit my standard TRX-4? — These front lower suspension links are specifically designed for use with the Traxxas #8140X TRX-4 Long Arm Lift Kit. If you have the Long Arm Lift Kit installed, these links will fit perfectly. If you're running a standard TRX-4 without the lift kit, you'll need to install the lift kit first to use these components.
- What makes hollow ball assemblies better than solid alternatives? — Hollow ball joints reduce the overall unsprung mass of the suspension system, which improves how quickly the suspension can respond to terrain changes. This lighter, more responsive suspension translates to better articulation, improved grip, and more precise vehicle control when navigating challenging obstacles and rough terrain.
- Are these suspension links compatible with other Traxxas models? — No, these links are engineered specifically for the TRX-4 in combination with the Long Arm Lift Kit. They are not compatible with other TRX models such as the TRX-6 or TRX-8, as those vehicles use different suspension geometries and component specifications.
- How do the powder-coated steel links compare to aluminium alternatives? — Steel provides superior strength and durability compared to aluminium, and the powder coating offers excellent corrosion resistance. Steel also provides better flex characteristics for rock crawling applications, allowing the suspension to absorb shock loads without permanent deformation. The powder coating adds a protective layer that shields the steel from mud, water, and UV exposure during extended off-road use.
- What's the difference between the hollow ball pre-assembly and standard ball joints? — The hollow ball design pre-assembled at the factory eliminates the need for you to assemble this critical component, ensuring proper fitment and geometry right out of the box. The hollow design reduces weight while maintaining rigidity, contributing to better overall suspension performance.
- Can I install these myself or do I need professional help? — Most RC enthusiasts with basic mechanical knowledge and standard RC tools can install these suspension links. However, if you're unfamiliar with suspension work, it's worth consulting Traxxas installation guides or visiting a local RC hobby shop in the UK where experienced staff can help you get everything set up correctly.
