QA1 KFR5 K Series 3-Piece Carbon Steel Female Rod End 5/16-24 RH — image 1

Product Details

The QA1 KFR5 is a K Series three-piece carbon steel female rod end designed for high-load, precision suspension and steering applications. Built to tighter tolerances than standard two-piece designs, the KF Series features a higher ball-to-race conformity that makes it well-suited for performance builds where precision is critical.

The body is constructed from carbon steel with a protective corrosion-resistant coating, while the ball is made from 52100 bearing steel — heat treated, precision ground, and hard chrome plated for long-lasting durability. The alloy steel race is engineered for wear resistance. This metal-to-metal rod end accepts right-hand threads and features female mounting with a 5/16" bore and 5/16-24 thread pitch.

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.
