Each shackle measures 9\" long by 2\" wide with 1\/4\" thick steel construction, a 1\/2\" bolt hole, and hole centers spaced 1\" apart—giving you room to fine-tune alignment or lift while keeping installation straightforward. The powder-coated finish helps protect against rust from road spray and weather, and packaging includes four matching shackles so you can replace a full axle set in one job.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these shackles change ride height or leaf spring angle?\u003c\/h3\u003e\n\u003cp\u003eAdjustable shackles alter the mount point of the leaf spring relative to the axle, which shifts the static ride height slightly and can change spring arch tension. By selecting a different hole position you can achieve incremental lift or re-center the axle when springs sag.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFour-position spacing allows small, controlled height changes.\u003c\/li\u003e\n  \u003cli\u003e1\/4\" steel thickness balances strength with manageable weight.\u003c\/li\u003e\n  \u003cli\u003e1\/2\" bolt hole matches common U-bolt and shackle hardware sizes.\u003c\/li\u003e\n  \u003cli\u003eWorks best for minor lift needs, trim adjustment, or replacing worn shackles.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these fit my vehicle or trailer?\u003c\/h3\u003e\n\u003cp\u003eThese are universal shackles not tailored to a specific make or model; fit depends on your spring eye width and bolt diameter.
