It measures 3-1/2 inches wide by 20-5/8 inches long on each side and uses a hook-style eye on one end and a standard eye on the other. Typically rated at 9,000 lbs capacity, this spring is designed for Trailmobile's parallelogram and short rocker cast suspensions. Leaf springs can weaken or break over time, leading to trailer sagging, uneven tire wear, or a harsh ride, so replacing worn springs helps maintain proper ride height and load stability.
