QA1 EXFL16-1 EX Series Carbon Steel Rod End Female Left Hand 1in Bore 1-14 UNS Thread

The QA1 EXFL16-1 is an EX Series Endura carbon steel female rod end featuring a loader slot design with a 1-inch bore and 1-14 UNS left-hand threads. As an economical alternative to chromoly and alloy steel rod ends, QA1's EX Series carbon steel construction delivers excellent strength and durability across a wide range of suspension applications including control arms, trailing arms, and panhard bars.

The body features increased cross-sectional thickness for greater tensile strength, while the reinforced Nylon 12 race is injection molded with self-lubricating PTFE to resist dirt and debris intrusion without pounding out like conventional race styles. This dual-mode design provides metal-to-metal support under heavy shock loads while ensuring smooth, low-friction operation under lighter loads.
