It provides a 10,000 lb capacity per spring and serves as a direct replacement for the original Fruehauf spring, part number UCD000511‑001. Springs like this are changed out when leaves fatigue, crack, or lose their arch, leading to sagging or poor ride height. Always recommended to replace in pairs to keep even suspension performance.
