Product Details

The QA1 KFL8 is a KF Series three-piece carbon steel female rod end featuring a 1/2 in. bore and 1/2-20 left-hand thread. Built for precision and high-load applications, this rod end delivers tighter tolerances through a higher ball-to-race conformity design — making it an excellent choice for demanding suspension, steering linkage, and performance fabrication work.

Key Features:

  • Three-piece construction with female mounting and 1/2 in. bore
  • 1/2-20 UNF left-hand thread for use in applications requiring reverse-threaded fasteners
  • Ball: 52100 bearing steel — heat treated, hard chrome plated, and precision ground for strength and wear resistance
  • Race: Alloy steel, corrosion and wear resistant
  • Body: Carbon steel with protective coating for corrosion resistance
  • Higher ball-to-race conformity for tighter tolerances in precision applications
  • Open, non-relubricatable enclosure (metal-to-metal style)
  • Available individually (sold each)

QA1's KF Series rod ends are engineered for both street and motorsport applications where consistent performance and dimensional accuracy are critical. The hard chrome plated ball and protective body coating extend service life even in harsh operating environments.

Thank You!! Good price!

easy

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

Had by far the cheapest place on the internet for the part I was looking for! Shipping was extremely fast as well! A++

All pieces ordered were shipped promptly and arrived in very great shape. I will be ordering from this site again.

Good prices. Good communication.
