Product Details

The QA1 KFL7SZ is a K Series 3-piece carbon steel female rod end featuring a left-hand thread, stud mounting configuration, and an integrated Zerk (ZRK) grease fitting for easy lubrication maintenance. Designed for high-load suspension, steering, and linkage applications, this rod end delivers precision performance and long-lasting durability.

The K Series is QA1's traditional three-piece carbon steel rod end line, built to exacting tolerances for use in racing, custom fabrication, and performance street applications. The stud (S) configuration simplifies installation in applications where a standard threaded shank is not practical.

Key Features:

  • Thread: 7/16 in.-20 Left-Hand Female Thread
  • Bore: 7/16 in. (0.4375 in.)
  • Configuration: Stud-type with Zerk grease fitting
  • Construction: Traditional 3-piece design
  • Body: Carbon steel with protective coating for corrosion resistance
  • Ball: 52100 bearing steel, heat treated, precision ground, hard chrome plated
  • Race: Alloy steel, corrosion and wear resistant
  • Available in left-hand thread for use with adjustment sleeves and tie rod assemblies

The included Zerk fitting allows for periodic re-greasing to extend service life, making the KFL7SZ well-suited for street-driven vehicles and applications subject to regular maintenance intervals. Left-hand thread models are commonly paired with right-hand counterparts in adjustable tie rod and suspension link assemblies.
