QA1 K Series 3-Pc Rod End - Female/Left Hand - .3125in Bore x 5/16-24 w/Stud - Carbon Steel w/PTFE

This is a QA1 K Series 3-piece rod end, specifically a female, left-hand threaded unit with a .3125 inch bore. It's designed for applications where a precise connection and smooth movement are needed, often found in custom suspension setups or steering linkages. The carbon steel construction offers a solid foundation, while the PTFE liner helps reduce friction for improved articulation.

The .3125 inch bore means it's intended for a 5/16 inch diameter shaft or bolt, and the 5/16-24 thread size is common in many automotive and performance applications. Having the stud integrated into the rod end simplifies installation in certain scenarios, as it provides a direct attachment point. This type of rod end is a well-built component for building or repairing linkages that require a pivot point with controlled movement.
