Product Details

The QA1 HMR12 is a precision-engineered H Series male rod end featuring traditional three-piece chromoly steel construction for superior strength and durability. Designed for high-performance automotive and racing applications, this rod end delivers tighter tolerances through enhanced ball-to-race conformity, making it ideal for precision builds where exact specifications are critical.

Key Specifications:

  • 3/4 inch bore diameter
  • 3/4-16 right-hand male thread
  • Three-piece alloy/chromoly steel construction
  • Heat-treated body for maximum strength
  • Available with optional grease fittings and stud configurations

Construction Details:

  • Ball: 52100 bearing steel, heat treated, hard chrome plated, and precision ground for smooth articulation
  • Race: Chromoly heat-treated steel with corrosion and wear-resistant properties
  • Body: Heat-treated chromoly steel with protective coating for corrosion resistance

QA1's H Series rod ends utilize a proven three-piece design where the ball is pressed into a sleeve and swaged to create the insert. This manufacturing process ensures better ball-to-race conformity compared to standard designs, resulting in tighter tolerances and more precise operation. The rod end is ideal for suspension linkages, steering connections, and other applications requiring precision articulation and heavy-duty reliability.
