QA1 KML5-6TS K Series 3-Piece Carbon Steel Rod End 5/16in Bore 3/8-24 LH Male Thread PTFE Lined with Stud

The QA1 KML5-6TS is a K Series three-piece carbon steel male rod end featuring a self-lubricating PTFE liner and a pre-attached stud. Engineered for precision and durability, this rod end is built for high-load applications in racing, performance, and custom fabrication environments. The left-hand male thread configuration makes it ideal for use in adjustable linkage systems such as steering tie rods, control arms, and clutch linkages.

The pre-attached stud uses right-hand threads for easy connection and provides greater misalignment capability compared to standard bolt-mounted rod end applications. The carbon steel body receives a protective coating for corrosion resistance, while the precision-ground, hard chrome plated 52100 bearing steel ball ensures smooth articulation and long service life under demanding conditions.
