Made from low carbon steel with a plain finish, each perch is shaped to fit over a 2-3\/8\" outside-diameter axle tube and accept common leaf spring widths. The parts are precision punched with a central 5\/8\" bolt hole and two 1\/2\" bolt holes to match standard U-bolt and center-bolt layouts, simplifying alignment and installation when building or repairing trailer suspension systems.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these perches attach to my axle and spring?\u003c\/h3\u003e\n\u003cp\u003eEach perch is a weld-on saddle sized to sit flush against a 2-3\/8\" OD axle tube and cradle the leaf spring leaves.
