Leaf spring perch

weld-on leaf spring plates fit 3" diameter axles but can be modified to fit 2-3/4" to 3-1/4" diameter axles. They have multiple center pin styles to fit a variety of 2" to 2-1/2" wide leaf spring packs. 

The front and back edges of the plates have a radius so they can be used in a spring under or spring over application. On a spring over application, if you launch your truck and bend the leafs all the way into a negative arch, the plates won't dig into your leaf.
