5mm plastic ball joints

The detail that brings precision back to your slot car steering

The ball joints are one of the most silent wear points of a slot car: they work in every corner, absorb vibrations, and when their plastics deteriorate, the steering loses consistency without us always knowing exactly why. These 5 mm ball joint plastics (reference TA50596) are the direct replacement to restore that original fit.

Function and performance

The ball joint plastic acts as a connecting and damping element between the metal ball joint and the part to which it is anchored. With continued use —especially in cars that run on abrasive tracks or that frequently experience crashes— this component wears out, cracks, or loses its fit. The result is unwanted play in the steering that directly affects the line.

• Diameter: 5 mm
• Contents: 6 units per pack
• Reference: TA50596

Installation and preparation

The change is straightforward: simply remove the worn plastic from the ball joint, clean the area, and place the new one ensuring it is well seated without play. It is advisable to check the condition of the ball joints every few sessions, especially in competition cars where the front geometry is critical for cornering performance.

Having a spare pack in the workshop drawer prevents interruptions in the middle of a setup or just before a club day.

Common mistakes

• Forcing the installation if the plastic does not seat naturally: it may crack immediately.
• Ignoring wear until the steering becomes completely loose, which can damage other parts of the front end.
• Using an incorrect diameter: always check that the ball joint of your car accepts the 5 mm size before installation.

Frequently asked questions

Which cars are compatible with these 5 mm ball joint plastics?

Compatibility depends on the ball joint installed in the car. It is necessary to verify that the diameter of your model's ball joint is 5 mm before placing the order. Consult the manufacturer's manual or measure the existing ball joint directly.

How many units does the pack include?

The pack contains 6 units, sufficient for several maintenance interventions or to have spares on hand during a racing season.

How often should I check or change these plastics?

It depends on the use of the car. In regular competition, it is recommended to inspect them every few race days. If you notice play in the steering or imprecise behaviour in corners, it is the first point to check.

Do I need special tools for the change?

In most cases, a pair of fine-tipped pliers and a small screwdriver are sufficient. No specialised machinery is required, although a clean work surface and good lighting greatly facilitate the task.
