Each saddle is designed for weld-on installation to a 2-3\/8\" outer diameter axle tube and provides a stable platform for 1-3\/4\" or 2\" wide leaf springs. The dimensional design and bolt-hole pattern let you line up center and retainer bolts precisely for safe spring positioning and repeatable alignment during axle rebuilds or custom trailer builds.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these spring perch seats attach to the axle?\u003c\/h3\u003e\n\u003cp\u003eThe seats are meant to be welded directly to a 2-3\/8\" OD round axle tube. Their curved underside matches the axle diameter for a secure weld fillet, and the flat top accepts the leaf spring's contact area. Proper welding by a competent fabricator ensures long-term stability under towing loads.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eWeld-on design tailored for 2-3\/8\" outer diameter round axle tubes\u003c\/li\u003e\n  \u003cli\u003eCurved base promotes consistent weld penetration and fit-up\u003c\/li\u003e\n  \u003cli\u003ePlain finish ready for welding and post-weld coating\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the exact dimensions and bolt patterns?\u003c\/h3\u003e\n\u003cp\u003eEach saddle measures 4\" long, 1-7\/8\" wide and 1-3\/16\" high, made from 7\/32\" thick low carbon steel.
