The QA1 XFR10 is an XF X-Series female rod end, a heavy duty chromoly steel rod end commonly used on four-link and ladder bar setups where strength and durability matter. The injection molded race is self-lubricating and self-sealing, which helps keep dirt and debris out. The ball is 52100 bearing steel that is heat treated, hard chrome plated and precision ground, and the body is heat treated chromoly steel with a protective coating for corrosion resistance. Metal to metal support handles heavy shock loads, and added cross-sectional thickness increases tensile strength.
