TRX5355X

Overview

The Traxxas Hollow Ball Set (TRX5355X) is an essential upgrade and maintenance component for RC enthusiasts in the UK who demand precision steering and suspension performance from their Traxxas RC vehicles. Whether you're a competitive racer, weekend basher, or serious hobbyist, this comprehensive hollow ball set provides everything you need to maintain, repair, or upgrade your RC car's suspension geometry and steering linkage. High-grade aluminium construction ensures durability whilst maintaining the lightweight characteristics that serious RC car UK builders and drivers rely on for optimal performance and handling.

Hollow balls are critical components in RC suspension systems, forming the connection points between your steering rods, suspension links, and chassis. Over time, these wear out through regular use, causing play in the steering and suspension that degrades handling precision and responsiveness. The Traxxas Aluminium Hollow Ball Set addresses this by providing a complete replacement kit with premium aluminium construction that delivers smooth, even steering and suspension action for pure performance. This is the kind of upgrade that separates weekend bashers from serious competitors, making it an investment in your RC car UK setup that will pay dividends in handling and longevity.

Specifically designed for Traxxas vehicles, particularly Revo models and other vehicles using standard Traxxas suspension geometry, this set combines practical replacement components with advanced tuning options in a single package. The inclusion of bump steer adjustment shims means you can fine-tune your suspension geometry for different track conditions, racing styles, and terrain types—something that ready to run RC beginners often don't realise is possible, but which experienced builders and competitors use constantly to dial in their vehicles.

Key Features

• 30 Aluminium Hollow Balls — This generous quantity ensures you have plenty of replacement components on hand for maintenance, repairs, or complete suspension rebuilds without having to wait for reordering, which is essential for keeping your RC car UK setup running at peak performance between races or sessions.
• High-Grade Aluminium Construction — Made from premium aluminium with protective coating, these hollow balls resist corrosion and wear whilst remaining lightweight, which is crucial for maintaining precise suspension geometry and steering response that directly impacts how your RC vehicle handles on track or terrain.
• 2 Tall Centred Hollow Balls — These precision-engineered balls provide standard suspension geometry for balanced handling characteristics, ensuring that your steering feel and suspension compliance remain predictable and responsive across all driving conditions.
• 2 Tall Offset Hollow Balls — These geometry-adjusting components allow you to modify your suspension linkage angles and steering geometry without replacing entire suspension arms, offering significant tuning flexibility for track-specific setups or experimenting with handling characteristics.
• Bump Steer Adjustment Shims (3.5mm, 2 pcs) — These precision shims enable fine-tuning of bump steer characteristics, allowing you to eliminate or adjust how your suspension geometry changes during compression, which directly impacts how your RC car UK handles over rough terrain or during aggressive cornering.
• Bump Steer Adjustment Shims (1.17mm, 2 pcs) — The inclusion of multiple shim thicknesses provides granular tuning control, allowing experienced builders to make micro-adjustments to suspension geometry for competition-level setup precision.
• Ready-to-Install Design — All components are supplied in a complete set with everything needed for maintenance or upgrade work, eliminating the frustration of having to source individual parts from multiple suppliers and getting your RC car UK back to action quickly.
• Enhanced Steering Precision — The aluminium hollow ball design delivers smooth, consistent steering feel without flat spots, binding, or play, which means your inputs translate directly into vehicle response without delay or uncertainty.

Technical Performance

The Traxxas Aluminium Hollow Ball Set represents the culmination of decades of Traxxas engineering expertise in RC suspension systems. Each hollow ball is precision-manufactured from high-grade aluminium alloy and features a durable protective coating that resists corrosion from dirt, moisture, and the wear that comes from extended use. The hollow design reduces unsprung weight whilst maintaining structural rigidity, which is fundamental to maintaining precise suspension geometry and steering response. At the heart of RC performance—whether you're running a brushless RC buggy, RC monster truck, or any other Traxxas vehicle—is the suspension geometry and steering system, and every component in this set plays a critical role. The 30 hollow balls provide a comprehensive replacement set covering front and rear suspension linkages, steering rods, and suspension arms across typical Traxxas four-wheel-drive and two-wheel-drive vehicles. The tall centred and tall offset options allow you to adjust suspension geometry precisely, critical for dialling in your RC car UK setup for different terrain conditions, driving styles, or competition requirements. The inclusion of bump steer adjustment shims in two different thicknesses (3.5mm and 1.17mm) demonstrates Traxxas's commitment to enabling serious builders and competitors to achieve professional-level setup tuning. Bump steer—the tendency for suspension geometry to change during compression—is one of the most subtle yet impactful aspects of RC vehicle setup, and having these shims allows you to eliminate negative bump steer characteristics that cause unpredictable handling during aggressive driving or over rough ground.

Frequently Asked Questions

• What is a hollow ball in RC suspension? — A hollow ball is a spherical joint component that connects suspension arms, steering rods, and linkages together, allowing them to move and flex whilst maintaining precise geometry. The hollow design reduces weight compared to solid balls whilst maintaining strength. Over time, these wear out and develop play, degrading steering precision and suspension response, which is why replacement sets like this are essential maintenance items.
• How often should I replace hollow balls on my RC car? — This depends on how frequently and aggressively you drive. Casual weekend bashers might replace them every few months, whilst competitive drivers at RC racing UK events might replace them every few weeks. When you notice play or sloppiness in the steering or suspension, it's time to replace them. Having a spare set on hand means you can perform maintenance immediately without downtime.
• What's the difference between centred and offset hollow balls? — Centred hollow balls maintain standard suspension geometry, whilst offset balls allow you to adjust the mounting height of suspension links and steering rods without replacing entire arms. This enables geometry tuning for track-specific setups or experimenting with how your RC car UK handles different conditions.
• Can I use these on any Traxxas vehicle? — These components are specifically designed for Traxxas vehicles with standard Traxxas suspension geometry. Confirm compatibility with your specific model (particularly common on Revo and similar models), though most modern Traxxas four-wheel-drive and two-wheel-drive vehicles use these standard components. Contact our team if you're unsure about compatibility for your specific setup.
• What are bump steer shims and why do I need them? — Bump steer refers to unintended changes in your vehicle's steering geometry as the suspension compresses over bumps or during aggressive cornering. Bump steer shims adjust the steering linkage mounting angles to minimise or eliminate this effect, resulting in more predictable, controllable handling that's particularly noticeable at high speeds or on rough terrain. The two different thicknesses allow micro-adjustments for fine-tuning.
• Do I need special tools to install these? — Installation is straightforward with basic RC hobby tools. You'll need a hex wrench or Allen key to remove and install the hollow balls on your existing rods and suspension arms. No special tools are required, making this a maintenance task that even intermediate RC builders can handle themselves.
• Is this suitable for beginners? — Whilst hollow ball replacement is a fundamental maintenance skill that every RC hobbyist should develop, this particular set is most valuable for builders and drivers who are familiar with their vehicles' suspension geometry and are ready to invest in precision tuning. Absolute beginners might start with a ready to run RC car and learn these maintenance skills as they progress, but any RC enthusiast committed to serious performance will find this set invaluable.
