This genuine Traxxas replacement part is engineered to exacting standards and is the only specification guaranteed to work perfectly with your Long-Arm Lift Kit setup.

Technical Performance
The Traxxas TRX-4 Front Upper Suspension Link TRX8144 is engineered with precision and built to handle the demanding requirements of modern RC crawling. The blue powder-coated steel construction provides exceptional durability whilst maintaining a professional appearance that complements your crawler's aesthetics. The 5x68mm dimension is specifically optimised for front upper suspension geometry when running the Long-Arm Lift Kit, a popular upgrade choice for UK RC enthusiasts looking to improve ground clearance, approach angles, and overall trail capability. The hollow ball joints come pre-installed, meaning the component is immediately ready for installation without requiring any additional assembly, tools, or adjustment. This level of engineering attention to detail is characteristic of Traxxas as a manufacturer, and it means you can have confidence in both the performance and longevity of this suspension component. The powder coating provides a protective layer that resists corrosion from moisture, mud, and the elements, which is particularly important for crawlers regularly used in varied weather conditions common across the UK. The hollow ball design is superior to solid alternatives because it reduces unsprung weight whilst maintaining full strength and articulation, contributing to more responsive handling and better trail feedback.

Frequently Asked Questions
- Is this suspension link compatible with my standard TRX-4 without the Long-Arm Lift Kit? — No, this part is specifically engineered for use with the Traxxas TRX-4 Long-Arm Lift Kit (part #8140). If you are running a standard TRX-4 without this lift kit, you will need a different suspension link specification. Always verify which suspension kit you have installed before ordering replacement components.
- How do I know when my suspension links need replacing? — Suspension links should be inspected regularly for visible cracks, bending, or damage to the ball joints. If you notice loose steering, unusual suspension behaviour, or visible wear on the hollow balls, it's time to replace the affected links. Regular inspection after heavy use or crashes will help you catch problems before they affect handling.
- Can I use suspension links from other TRX-4 models? — No, the correct dimension specification is critical for proper suspension geometry. The 5x68mm specification in this product is specifically for the Long-Arm Lift Kit setup. Using incorrect lengths will result in poor handling, improper ride height, and potentially dangerous suspension geometry issues. Always use the exact specification for your particular suspension configuration.
- Do these suspension links come assembled? — Yes, absolutely. These suspension links arrive completely pre-assembled with hollow ball joints already installed and ready to use. You do not need to perform any assembly work, and this eliminates any possibility of incorrect installation of the ball joints.
- What is the difference between this and standard TRX-4 suspension links? — The primary difference is the dimension specification. The 5x68mm size is optimised for the geometry of the Long-Arm Lift Kit, which raises the suspension mounting points to accommodate the taller lift kit design. Standard TRX-4 models use different length specifications that would result in poor geometry if used with the lift kit.
- Is this part suitable for beginners? — Yes, this is a straightforward replacement component suitable for TRX-4 owners of any experience level. Installation involves removing the old link and installing the new one, which is a basic maintenance task. If you are unfamiliar with TRX-4 suspension service, the Traxxas manual for your specific model will provide clear installation instructions.
- How many of these do I need? — Each vehicle has one front upper suspension link per side, meaning two suspension links are needed for a complete front upper suspension setup. This product contains one link, so you may wish to order two if you need to replace both sides.
