FK Bearings has earned its reputation as one of the world's leading manufacturers of precision spherical bearings, supplying components trusted throughout professional motorsports including desert racing, NASCAR, IMSA, off-road racing, road racing, and many other forms of competition.

Why Choose a Uniball?

Unlike conventional ball joints, uniballs are designed for applications requiring greater suspension travel, increased articulation, and higher load capacity.

Benefits include:

• Increased suspension travel
• Greater angular misalignment
• Reduced binding throughout suspension movement
• Exceptional radial and axial load capacity
• Smooth, precise articulation
• Easily serviced and replaced
• Ideal for fabricated control arms and long-travel suspension systems

For these reasons, uniballs have become the preferred suspension pivot in professional motorsports and high-performance off-road vehicles.
