OTR Premium High Arch Trailer Leaf Spring, 3-Leaf, 11,200 lb Capacity, 3.00" Width, 6.00" Arch. This heavy-duty replacement leaf spring is engineered to restore trailer suspension height and load-bearing capability for Binkley, Hutch and similar trailer suspensions. Rated for 11,200 lb at the pad and specified with a 6.00" arch and 3.00" width, the assembly replaces worn or damaged springs to reestablish designed axle geometry and axle-to-frame spacing. Installing a matched high-arch spring addresses sagging suspension that otherwise shifts load distribution, increases tire wear, and raises the risk of uneven brake loading. The three-leaf construction and listed arch dimension provide a direct approach to recover spring capacity and reduce progressive overload on adjacent components, helping maintain consistent ride height under rated loads. For fleet operations, predictable spring capacity and repeatable arch measurement translate into measurable operational value: more consistent tire life, fewer premature hanger and shackle repairs, and reduced downtime from unexpected suspension failures. The springs long and short end lengths and hook/slipper end types are manufactured to the TRA2726 replacement geometry specified by trailer OEM interchange references, enabling fitment where that geometry is required. This leaf spring is offered as a single assembly for targeted replacement during asset maintenance cycles or as part of scheduled axle-level spring set renewals. Specified attributes support decisions for preventive maintenance planning, life-cycle cost calculations, and parts staging to minimize trailer out-of-service time.
