Key Features
- Precision Engineering for TRX-4 Long Arm Lift Kit Compatibility — These rear upper suspension links are specifically engineered to work seamlessly with the #8140X TRX-4 Long Arm Lift Kit, ensuring perfect fitment and optimal performance. This dedicated design means you get the exact geometry and specifications needed to maximise your suspension upgrade investment and achieve the handling characteristics the kit was designed to deliver.
- Premium Powder-Coated Steel Construction — The links are manufactured from high-quality steel with a durable powder-coat finish in eye-catching blue. This construction method provides excellent strength-to-weight ratio whilst the powder coating offers superior corrosion resistance compared to bare metal or simple paint finishes, making these links suitable for serious trail use in all UK weather conditions.
- Hollow Ball Joints for Precise Movement — Assembled with hollow ball connections, these suspension links deliver precise articulation and smooth movement through your suspension travel. Hollow ball joints are preferred in high-performance RC applications because they allow unrestricted rotation whilst minimising binding, which translates to better handling, improved traction, and more responsive steering feel on challenging terrain.
- Optimal Dimensions for Suspension Geometry — At 5x115mm, these suspension links are engineered to the exact specifications required for the Long Arm Lift Kit system. The specific dimensions ensure proper suspension angles and geometry, which directly impacts how your truck climbs obstacles, maintains traction, and responds to steering input. Correct suspension geometry is fundamental to unlocking the full potential of your TRX-4 crawler.
- Complete Pair Included — You receive two suspension links in this package, providing the complete rear upper suspension link set for your TRX-4. This ensures you have all the components needed for a proper suspension upgrade without the inconvenience of ordering multiple packages.
- Professionally Assembled — The links come pre-assembled with the hollow ball joints already installed, saving you assembly time and ensuring professional-quality installation. This is particularly valuable if you're working on multiple upgrade projects or want to get your TRX-4 back on the trail quickly with confidence in component quality.
Technical Performance
These Traxxas rear upper suspension links represent the engineering excellence that has made Traxxas the choice of RC crawler enthusiasts throughout the UK and beyond. The 5x115mm dimension provides the correct suspension geometry for the Long Arm Lift Kit system, which dramatically increases suspension travel and ground clearance compared to stock setups. The powder-coated steel construction delivers the strength required for aggressive trail use whilst remaining lightweight enough to maintain optimal weight distribution.

When combined with the #8140X TRX-4 Long Arm Lift Kit, these suspension links help your TRX-4 achieve superior obstacle-climbing ability, improved ground clearance for technical terrain, and the suspension geometry necessary for professional-level trail performance. The blue finish matches perfectly with upgraded suspension packages and delivers the visual style that serious RC builders appreciate. These components are thoroughly tested and proven in the field by professional RC drivers and serious hobbyists who demand nothing less than Traxxas quality and performance.

Frequently Asked Questions
- Are these suspension links compatible with my TRX-4? — Yes, these rear upper suspension links are specifically engineered for use with the #8140X TRX-4 Long Arm Lift Kit. They are not designed for use with standard TRX-4 suspension geometry, so compatibility is assured when used with the correct Long Arm Lift Kit. If you're running stock suspension, you would need the standard suspension links rather than these rear upper links.
- What is the advantage of the Long Arm Lift Kit suspension upgrade? — The Long Arm Lift Kit system significantly improves your TRX-4's capability on challenging terrain by increasing suspension travel, raising ground clearance, and improving suspension geometry. The kit helps your truck climb steeper obstacles, navigate rough ground with better articulation, and maintain traction in extreme conditions. These rear upper suspension links are essential components that work together with the rest of the kit to deliver these performance improvements.
- Why choose powder-coated steel instead of aluminium? — Steel provides superior strength and durability for suspension components that experience constant stress during trail use. The powder-coat finish offers excellent corrosion resistance whilst maintaining the strength characteristics needed for reliable performance. Steel construction is the professional choice for trail trucks and crawlers that see serious use.
- Do these links come pre-assembled? — Yes, these suspension links arrive fully assembled with the hollow ball joints already installed. This saves you assembly time and ensures professional-quality installation, allowing you to focus on installation rather than component preparation.
- What is the difference between hollow ball joints and standard connections? — Hollow ball joints allow unrestricted rotation and movement without binding, delivering smoother suspension articulation and more responsive handling. This design is preferred in high-performance RC applications because it minimises friction and allows your suspension to work more efficiently through its full range of motion.
- Will these links improve my TRX-4's trail performance? — When used as part of the #8140X Long Arm Lift Kit system, these rear upper suspension links contribute to significant performance improvements including better obstacle climbing, improved ground clearance, enhanced suspension articulation, and more predictable handling. The correct suspension geometry delivered by these components is essential for unlocking the full potential of the Long Arm Lift Kit upgrade.
