QA1 H Series 3-Piece Alloy Rod End

The QA1 H Series 3-Piece Alloy Rod End (also called a heim joint or rod end bearing) is a precision spherical rod end for suspension links, steering linkages, and other motion-control uses. It uses a traditional three-piece design: a ball, a race, and a body. QA1 builds its suspension components for muscle cars, classic trucks, race cars, and industrial applications.

Key Features:

• Three-piece construction: The ball, race, and body are separate parts, a traditional design for precision rod ends.
• Alloy/chromoly steel body: The body is heat treated and has a protective coating for corrosion resistance.
• Precision-ground ball: The ball is made of 52100 bearing steel. It is heat treated, precision ground, and hard chrome plated.
• Tight tolerances: The design has high ball-to-race conformity, which suits precision applications where tight tolerances matter.
• Thread options: The series is offered in right-hand and left-hand threads, with male and female configurations.
• Optional configurations: Depending on the part number, versions with a self-lubricating PTFE liner, greaseable designs, and stud-mounted designs are available.

The H Series gives builders and fabricators a durable, precise rod end for chassis and suspension work.
