Leaf spring parts FAQ
What’s the difference between a perch, hanger and shackle?
A perch is the spring seat on the axle. A hanger attaches at the frame. A shackle pivots at the spring eye as the leaf pack moves. Start with the attachment point you’re replacing and then match the dimensions.
How do I pick a leaf spring perch?
Match spring width and axle tube outside diameter, then check front or rear application and any offset. For example, MB4002 is an offset front spring-over perch for the YJ’s 2½-inch tube and 2½-inch-wide spring. A straight perch may put the spring in a different position.
How do I size a spring hanger or shackle?
For a hanger, measure the width of the spring eye and bushing assembly, and confirm bolt diameter. For a shackle, use pivot-hole center-to-center length. MB1538 universal hangers offer multiple inside widths, so select the matching variant before checkout.
Should I buy a stretch kit or separate spring hardware?
For a planned CJ or YJ rear stretch, start with the matching kit to get the bumper and shackle locations together. For a repair or custom axle layout, select the individual perch, hanger, shackle or bushing you need.
