Product details:

Available in both greaseable and non-greaseable versions, Daystar Super Shackles can handle anything you care to throw at them. Constructed of heavy-duty plate steel, they include a fully welded center bar that reduces deflection and axle shift while cornering or when the suspension is articulating. There are stock replacement versions as well as versions that provide up to 2-1/2 of lift; check the product description to see what's available for your application.
