Made from low-carbon steel with a 7\/32\" (5.6 mm) thickness, each perch accepts a center 5\/8\" bolt and two 1\/2\" fasteners, fitting 1-3\/4\" or 2\" leaf springs. The plain finished, weld-on design lets fabricators and DIYers secure spring packs to OD 3\" round axles without custom machining.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these perches install on a 3\" round axle?\u003c\/h3\u003e\n\u003cp\u003eInstallation is welded directly to the axle tube: the perch wraps the OD 3\" axle and is tack-welded in place, then fully welded for permanent attachment.
