It serves as the primary load-carrying spring on the rear axle, working alongside the air bags to support the trailer and cargo. With a combined capacity of roughly 19,000–20,000 lbs per spring, it is designed to be replaced in pairs when the original springs sag, crack, or break to restore proper ride height, alignment, and ride quality.
