OTR Premium High Arch Tapered Trailer Leaf Spring 3.00 in Width 11,200 lb Capacity. This single-leaf, high-arch tapered trailer spring is engineered to restore and maintain designed ride height and load-bearing capability for heavy-duty trailer suspensions. Built to the TRA-023 profile, the springs 3.00 in width, 1.375 in pack thickness and approximately 7.06 in free arch provide the vertical support needed to retain axle alignment under rated loads. For fleets, a spring replacement that returns a trailer to its rated 11,200 lb capacity reduces overloaded-axle events, prevents premature tire and brake wear, and preserves handling characteristics critical for safe, efficient operations. Specified long and short end lengths along the leaf surface (approximately 24.18 in and 22.50 in respectively) match common OEM mounting geometries used on Hutch, Binkley and similar trailer applications, simplifying parts selection and minimizing installation time when replacing like-for-like components. Using a direct replacement spring with documented arch, length, and load-rate attributes addresses operational issues such as sagging suspension, inconsistent trailer height during coupling, and altered load distribution that lead to increased maintenance cycles and unscheduled downtime. Measurable fleet-level benefits include restoration of rated payload capacity, reduction in axle overload occurrences, and improved service interval predictability by returning the suspension to specified ride characteristics. The component is manufactured under controlled production standards and is offered with standard parts coverage, providing traceable quality for maintenance planners. This leaf spring is intended for professional installation; matching spring arch class and pack configuration across an axle is advised to maintain balanced suspension performance and predictable handling in loaded and unloaded conditions.
