Key Features

• Complete 8-Piece Link Set — This comprehensive upgrade includes front lower arms (1 pair), front upper arms (1 pair), rear lower arms (1 pair) and rear upper arms (1 pair), allowing you to completely overhaul your TRX-4's suspension linkage in one purchase. Having all four link positions upgraded ensures consistent geometry and performance across the entire suspension system rather than mixing factory and upgraded components.
• CNC-Machined Aluminium Construction — Each component is precision CNC-machined from high-quality aluminium, delivering superior accuracy and repeatability compared to injection-moulded plastic alternatives. This manufacturing method ensures each arm is identical to its pair, critical for maintaining balanced suspension geometry that translates directly to predictable handling on the trail.
• Premium Silver Anodised Finish — The silver anodised coating provides multiple benefits including enhanced visual appeal, superior corrosion resistance against moisture and salt, and improved durability against the wear and tear of regular use. This finish protects the underlying aluminium from oxidation whilst maintaining the professional appearance of your build.
• Enhanced Durability Under Load — Unlike plastic links that can flex, crack or bend under the extreme articulation demands of serious crawling, these aluminium components maintain rigid geometry throughout full suspension travel. This is particularly important when your TRX-4 is navigating extreme obstacles, tight rock gardens or high-stress technical terrain where suspension geometry precision is essential for traction and control.
• Optimised Suspension Geometry — The precision engineering of the Vitavon links allows for more accurate suspension geometry throughout the full range of articulation, improving weight distribution, maintaining consistent contact patch pressure and enhancing your vehicle's ability to climb steep inclines and navigate challenging obstacles with superior stability.
• Easy Installation — These drop-in replacement arms utilise standard TRX-4 mounting points, making installation straightforward for anyone with basic RC mechanics knowledge. The compatibility with existing TRX-4 hardware and geometry means you don't need to source additional components or modify your chassis to achieve a complete upgrade.
• Scalable Platform for Further Upgrades — By upgrading to quality Vitavon components, you establish a foundation for additional CNC upgrades across your TRX-4 build. Many Vitavon owners expand their upgrades to include axle housings, suspension mounts and other drivetrain components, creating a completely optimised crawler platform.

Technical Performance

The Vitavon VITTRX9749SL link set represents a significant step up in build quality and engineering precision compared to the factory TRX-4 components. Each arm is manufactured using CNC machining processes that achieve tolerances measured in fractions of a millimetre, ensuring perfect symmetry between paired components. The aluminium material selected provides an optimal balance between weight savings and structural rigidity; it's significantly lighter than steel while maintaining the strength required for serious off-road use. The silver anodised finish is applied through an electrochemical process that creates a protective oxide layer on the aluminium surface, enhancing corrosion resistance and durability. For serious crawlers running factory TRX-4 diffs and transmissions, these upgraded links immediately improve articulation control, reduce suspension binding and enhance overall trail-handling characteristics. The precision engineering means that when your TRX-4 is flexed to its maximum articulation during difficult climbs, the suspension geometry remains consistent rather than degrading as plastic links flex and twist. This is particularly noticeable when attempting extreme obstacles where even small variations in geometry can mean the difference between successful completion and getting stuck. The upgrade is compatible with all standard TRX-4 hardware and requires no chassis modifications, making it an ideal component for phased platform development where builders upgrade critical suspension components over time.
