QA1 KMR12SZ K Series 3-Piece Carbon Steel Rod End 3/4 Bore Male Right-Hand Stud with Zerk

The QA1 KMR12SZ is a K Series three-piece carbon steel male rod end featuring a 3/4 in. bore, 3/4 in.-16 right-hand male thread, pre-attached stud, and a Zerk grease fitting for easy field lubrication. Engineered for high-performance automotive, racing, and street rod applications, this rod end delivers precise articulation and long service life in demanding environments.

QA1's KM Series rod ends are built using a traditional three-piece construction with a higher ball-to-race conformity, resulting in tighter tolerances and more precise movement compared to two-piece designs. The carbon steel body receives a protective coating for corrosion resistance, while the 52100 bearing steel ball is heat-treated and hard chrome plated for exceptional wear resistance.
