The bearings in the swingarm allow it to move smoothly and without friction. Over time, these bearings can wear out, which can lead to a variety of problems, such as:
- A loose or wobbly swingarm
- Difficulty turning the vehicle
- Decreased performance
- Increased wear and tear on other suspension components
Some kits also include other parts, such as dust caps and grease nipples.
It is important to note that arm bearing kits are not universal. Each vehicle has its own unique swingarm bearing assembly, so it is important to purchase a kit that is specifically designed for your vehicle.
