For hobbyists chasing smoother handling, the 3Racing blue ball end rear-end stiffener helps firm up the rear of the chassis. It is intended to limit flex and produce a more consistent rear axle behaviour during varied track conditions.
The ball end design promotes reliable alignment of the rear links, cutting slack that can upset balance. The result is a more predictable rear end that can help with lap time consistency or club event tuning.
This component fits many common rear link arrangements and installs with standard tools, making it a straightforward upgrade for weekend tuners and regular club racers.
