Product Details

QA1 Precision Products bearings are spherical bearings and rod end bearings built for suspension, steering, and linkage use. They give smooth, controlled articulation in performance street, racing, and off-road builds. The line is also known as spherical rod ends, heim joints, and rod end bearings.

Key Features:

  • Spherical bearing design allows misalignment and smooth multi-directional movement
  • Made from high-strength steel, including chromoly and 52100 bearing steel, depending on the variant
  • Precision-machined for tight tolerances and consistent fit
  • Commercial Series (COM) construction for durable, reliable performance
  • Suited to control arms, trailing arms, panhard bars, linkages, and other suspension and steering applications

QA1 is a well-known American manufacturer of suspension components for motorsports and performance vehicles. Pick the variant in this family that matches the bore, thread, and style your build needs.
