Spring Perches/Mounts
Leaf Spring Perches are welded on top or below your axle tube. Your leaf springs rest on top of the spring perch. Stock perches can collapse or get bent out of shape over time and need to be replaced. Also, if you are going to swap to a different axle, do a spring over conversion, install wider leaf springs, or relocate your springs, you will need spring perches to do the job right.
