Key Features
- Tall Centred Hollow Balls (2 pcs) — These components maintain the standard suspension geometry and are ideal for vehicles running stock suspension settings or for drivers who prefer neutral handling characteristics without bias towards either compression or extension.
- Tall Offset Hollow Balls (2 pcs) — The offset design allows you to adjust your suspension's geometric properties, enabling fine-tuning of your vehicle's handling balance and response to terrain changes, making them invaluable for competitive setup optimisation.
- Bump Steer Adjustment Shims 3.5mm (2 pcs) — These precision shims allow you to adjust bump steer correction by a larger increment, perfect for vehicles that require significant geometry adjustments or for drivers experimenting with different setup configurations.
- Bump Steer Adjustment Shims 1.17mm (2 pcs) — These finer adjustment shims provide incremental bump steer tuning capability, allowing you to dial in your suspension geometry with precision for that perfect balance between responsiveness and stability.
- Genuine Traxxas Manufacturing Quality — Every component in this kit is manufactured to Traxxas's stringent quality standards, ensuring reliability, durability and perfect fitment with your TRX-4 scale crawler platform.
- Universal TRX-4 Compatibility — Designed specifically for the entire TRX-4 range including the 2021 Ford Bronco crawler series, TRX-4 Defender 4WD RTR models, and TRX-4 Sport variants, providing drop-in compatibility across the platform.
- Essential Replacement and Upgrade Component — Whether you're replacing worn suspension components or upgrading your setup for improved handling, these hollow balls and shims are fundamental to maintaining and optimising your TRX-4's suspension performance.
Technical Performance
The Traxxas Hollow Ball kit represents precision engineering at the suspension level, delivering the components necessary for serious TRX-4 platform optimisation. Hollow ball suspensions are critical connection points in any RC crawler, responsible for maintaining suspension geometry whilst allowing articulation and travel. The tall centred hollow balls maintain standard suspension geometry, providing a baseline setup suitable for general crawling and standard driving conditions. The tall offset variants shift the suspension's geometric properties, enabling experienced builders and competitors to adjust ride height, anti-squat, anti-dive and overall handling bias. The bump steer adjustment shims work in conjunction with these hollow balls to fine-tune the amount of toe-in change that occurs during suspension compression and extension—a critical parameter for maintaining traction and predictable handling across technical terrain. The 3.5mm shims provide gross adjustment capability for significant geometry changes, whilst the 1.17mm shims enable precise micro-adjustments for dialled-in setup tuning. All components are manufactured from durable materials engineered to withstand the stresses of scale crawling, rock crawling competitions, and consistent bashng. For UK RC car enthusiasts building or maintaining a TRX-4 scale crawler, this component kit delivers the precision and versatility required to extract maximum performance from the platform.

Frequently Asked Questions
- What is the difference between centred and offset hollow balls? — Centred hollow balls maintain your TRX-4's standard suspension geometry and are ideal for stock setups or drivers preferring neutral handling. Offset hollow balls shift the suspension's geometric properties, allowing experienced builders to adjust ride height, anti-squat, anti-dive and overall handling bias for customised performance tuning.
- What do bump steer adjustment shims do? — Bump steer shims fine-tune the amount of toe-in change that occurs during suspension compression and extension. The 3.5mm shims provide larger adjustments for significant geometry changes, whilst the 1.17mm shims enable precise micro-adjustments for dialled-in competition setups.
- Why would I need replacement hollow balls? — Hollow balls are suspension connection points that experience constant wear during crawling, bashing and competition use. Over time they can develop play or wear, affecting suspension precision and handling. This kit provides replacements to restore your TRX-4's suspension performance.
- Is this suitable for beginners? — Whilst hollow balls are essential suspension components, replacing them requires basic mechanical knowledge and proper tools. Beginners new to RC car maintenance may find these parts easier to install with guidance from experienced RC enthusiasts or online build guides. These components are essential whether you're a beginner or experienced builder.
- Will these parts fit my TRX-4 immediately? — Yes, these genuine Traxxas components are engineered for drop-in fitment on all compatible TRX-4 models listed. No modifications are required, though you may need basic tools such as hex drivers and a suspension tool to remove old components and install new ones.
- Can I mix and match centred and offset hollow balls? — Yes, this is a common tuning strategy in competitive RC crawling. Many drivers run asymmetrical suspension setups using combinations of centred and offset hollow balls to fine-tune handling bias, responsiveness and terrain adaptation across different driving conditions.
