Our 1/4" offset shackle allows you to have a difference of a 1/2" between your leaf spring and spring hanger. These shackles are laser cut from 3/8" thick plate steel and have 1/2" bolt holes. We offer these shackles in three different lengths to better suit your application. Shackles are measured from the center of bolt hole to center of bolt hole. These shackles are sold individually, you will need two of these to make one complete shackle. Like all of our products, they are made in the USA from USA steel.
